Every healthcare provider in the US must be enrolled with payer networks (e.g. commercial insurance, Medicaid, etc.) to bill for services. However, the payer enrollment process is fragmented and time-consuming: each payer in every state has a unique process. This process is currently entirely manual and the complexity often leads to errors, causing months of delays and lost billings for providers.Ply Health standardizes and automates payer enrollment. Providers fill out a single form and our AI-powered connectors submit the correct forms and manage the cases until completion. In half a year, we’ve done over 3,000 enrollments for our customers and helped some of our customers halve their enrollment timelines, earning them hundreds of thousands of dollars more in revenue per provider.

# Perch Founding Engineer - Backend

**What is Perch?**

Perch is the first reading app for the Internet — all of your blogs and newsletters in one place. As more writing moves online, we believe this will comprise an increasingly larger percentage of all reading activity, and over time, we will be the #1 reading application/product in the world.

We ([Mike](https://x.com/mikemcg0) & [Matt](https://x.com/mattmcguin)) also believe that removing friction from the reading experience will expand the market for blogs and newsletters from mostly chronically online people today (where do you find blogs/newsletters if you’re not on X or Reddit?) to the 5+ billion people connected to the Internet.

Specifically, we’re focused on removing three key layers of friction:

1. **Cost**. Writing is shockingly expensive. Twenty dollars for a book or a ten dollar monthly subscription is out of reach for most people. Perch will make it free. Lots of great writers already publish their content online for free, so we'll start with those. Then, once we've hit the scale required to support tasteful advertising, we'll share the majority of that revenue with writers to attract writing that currently sits behind paywalls. YouTube demonstrates how effective this model can be: it'd be silly for MrBeast to paywall his videos today.
2. **Discovery**. Writing is scattered across millions of websites, newspapers, magazines, and books. Perch will index it all and show you exactly what you want to read, before you even knew you wanted to read it.
3. **Ease of use**. Highlighting, picking up where you left off, audio, summarizing, themes, fonts, adjustable text sizes, and bookmarking should all be seamless. And if your grandma can't figure out how to do it, it's too hard!

But don’t take our word for it, try the app for yourself [here](https://perch.app/).

A few dozen people are already using it almost every day even though we just released it to the app store a few weeks ago and have done very little to promote it. Our sole focus right now is getting the product to organic exponential growth solely via word of mouth. Some people are sharing it with friends already, but it’s not quite there yet.

Here are a couple of testimonials from real users we didn’t know personally before they downloaded Perch:

We’ve also raised $6M from some of the best VCs in the world — Reddit cofounder Alexis Ohanian’s 776 Ventures, Naval Ravikant, Balaji Srinivasan, and a few other angels.

For more on why we think building Perch is important, read our [mission statement](https://perch.app/about).

**The Role**

This founding engineer role would be our first hire, and we’re in the process of setting up an office in NYC. This role is 100% in-person, and we only plan on hiring people who are so smart/amicable that you’d go into the office on a Sunday just to hangout with them.

We’re looking for somebody who is obsessed with coding and loves hard engineering problems. Aptitude is more important than experience, in our view.

The problem you will be working with us to solve is:

1. Index all of the blogs and newsletters on the Internet with perfect formatting (You would not believe much bad HTML there is out there)
2. Build an article recommendation engine. Of the millions of articles on the Internet, can we show users the best possible thing for them to read at any given moment as soon as they open the app?
3. Scrape, ingest, and organize third-party and meta data to improve those recommendations. Internal backlinks is one obvious example and Google’s core insight — if Paul Graham links to a blog post, it’s probably pretty good. But we’ll also want to leverage external backlinks (e.g. The New York Times) and other useful third-party data (e.g. how many people shared this article on X or Reddit?). And of course our own reading data (e.g. Did readers finish this article? Did they click on it? Did they share it? Did they bookmark it?).

Our backend is written in Node.js but we generally believe that languages can be learned. Again, we believe that aptitude is more important than experience.

**One more thing**

We built this blog called the [Startup Archive](https://www.instagram.com/startuparchive_/) that has hundreds of thousands of followers across Instagram, X, LinkedIn, Threads, and newsletter.

It began as a way to dogfood our product and put ourselves in the shoes of people who write on line, but it has grown into this incredible distribution asset that can help share Perch with the millions of people it reaches per month.

We haven’t promoted Perch yet though. We’re waiting until the product is good enough to grow organically through word of mouth before pouring gasoline on it.

Recruiting is the highest-leverage action any company can take. Hundreds of billions are spent on staffing and recruiting per year because of how difficult yet critical it is. Hiring the best candidate for any role should take days, not months, and we believe we’re best positioned to solve this at scale with our AI-enabled recruiting marketplace.Our customers come to us with a hunch—that the only way to build an engineering team of 8 with secret clearance in D.C. or find an AI safety engineer in London is to outsource their recruiting efforts.

From engineering to healthcare, AI agents are transforming how people work. The most rapidly growing AI products access business systems (like ERP, CRM, etc.) to extract insights. However, agents currently can’t operate like humans – APIs are too restrictive, and hard-coded RPAs are too brittle. Statics is creating the foundational blocks to enable agents to authenticate and interact with systems just as humans do.Join us to shape the identity future for AI agents.

Statics

At Statics, we believe building a successful AI agent involves three key data layer pillars:<ol><li>Discovery: Identifying the data an agent needs to perform effectively and determining where this data is stored.</li><li>Authentication: Securely obtaining the necessary credentials for agents to access information.</li><li>Ingest: Cataloging and organizing the accessed data, and defining its governance.</li></ol>We believe all three pillars are critical, and we are actively developing solutions at the second pillar today.&nbsp;As a Software Engineer at Statics, you will be an essential part of the product development dialogue, working to enhance the developer experience in helping AI agents access the right data.

Software Engineer at Statics 

Statics is building the identity system for AI agents, allowing them to authenticate like humans so they can access data that’s available to people but not to APIs.

We’re a team of engineers who have built and hacked global-scale identity systems, backed by a16z and the founders and investors of leading startups and major identity companies.
About This Role
At Statics, we believe building a successful AI agent involves three key data layer pillars:

Discovery: Identifying the data an agent needs to perform effectively and determining where this data is stored.
Authentication: Securely obtaining the necessary credentials for agents to access information.
Ingest: Cataloging and organizing the accessed data, and defining its governance.

We believe all three pillars are critical, and we are actively developing solutions at the second pillar today. 

As a Software Engineer at Statics, you will be an essential part of the product development dialogue, working to enhance the developer experience in helping AI agents access the right data. Here are some features you may be working on: 
Building a React page to help developers debug an AI agent’s authentication flow
Building a new REST API route to enable developers proactive refresh authentication cookies 
Building end-to-end passkey support to give AI agents an easier time to authenticate to passkey-supporting websites 
Something you thought would help developers better adopt Statics and/or make our life easier 
About You
You are elegant yet pragmatic in your engineering approaches. 
Write good code, fast. 
You have some kind of spike: did exceptional work at a previous company, identified and joined a top startup early, excelled at a top school, or something else impressive
Bonus point: you have built AI agents before (even in hackathon projects) or are highly engaged in the AI developer community


Engineering Stack
Since many folks have asked, we are including our current stack here. It is not necessary to have experience with it. We care more about your engineering fundamentals and good intuitions. 

Backend: TypeScript with NestJS framework and Prisma ORM. 
Frontend: React

Founding Engineer at Pillar, NYC. On-site. No visa sponsorship. $90K-$150K. Must have experience in trading systems, Go, Typescript, Postgres, AWS, distributed systems, fintech. Design/build microservices, integrations, customer-facing front-end. Prioritize tasks, communicate transparently, collaborate effectively. Fast-paced startup experience essential. Passion for reshaping financial services.

Pillar protects global businesses from macroeconomic risk by automatically hedging their freight, currency, and commodities exposure.&nbsp;Risk management plays a critical role in the functioning of any business. In the past 4 years, volatility across these asset classes - swings from +20% to 450% - has wreaked havoc on SMEs who rely on them to function. Yet, the solutions needed to limit the effects of this volatility – seasoned traders and investment banking services – remain in the hands of the few: billion dollar companies with unlimited resources. Pillar solves this by bringing protection previously available only for the largest corporations to the 30M+ SMEs worldwide who have $7T+ of underserved risk. With a few clicks, customers are able to manage their risks through Pillar’s seamless, end to end platform.&nbsp;We’re on a mission to give all businesses Fortune 500-level financial services, starting with risk management, enabling them to focus on building their core business. We’re backed by world class investors like J Ventures, Neo, Graph Ventures, Ride Ventures, Expansion Ventures, the CEO of Uber and Co-Founder of Vanta, along with seasoned executives and operators from Stripe, Robinhood, and Airbnb.&nbsp;

Pillar

We are looking for a talented founding engineer to join us on our mission to bring transformative financial services to businesses globally. You will be working on designing, building and scaling Pillar’s platform alongside a strong team that has varied and thorough experiences in the domain being tackled. The ideal candidate will have experience working at a fast–paced engineering organization, and tackling complex problems. You will be expected to take solutions to problems from 0 to 1, and maintain full ownership over all services that you build. Over time, your role will grow and evolve with the company, including managing and mentoring new hires, and taking on an engineering leadership role.&nbsp;While a prior background in fintech would be helpful, it is not a requirement; we will teach you the domain knowledge you will need. Ultimately, we look for people who are always eager to learn and willing to go the distance as we continue on our journey to reshape financial services for the millions.&nbsp;

Ask yourself: why do some companies drop [90%] of their share price in 2 years, get acquired by private
equity and then turn profitable in the next 1 year. With no real change to their customer or product.
The single biggest reason behind these sub-par financial decisions are: fragmented financial data which
does not provide any forward-looking, actionable RoI insights to the decision makers. Such a broken set
up also leads to lack of time and attention from the accounting and finance teams, as they spend

Transformers feel magical -- they understand text at near-human level. Yet traditional search engines (cough, Google) don't feel magical -- they don't understand text at near-human level. It doesn't have to be this way.At Exa, we're training foundational models for search. Our goal is to build systems that can instantly filter the world's knowledge to exactly what you want, no matter how complex your query. Search is a unique research problem within generative AI -- instead of generating a single piece of text, search involves asking the same questions about billions of texts.No other AI lab is exploring this direction. That means if we don't find novel methods for search, they won't be found. Our team has already made breakthroughs not seen in the literature, and we have more coming. Want to explore the search frontier with us?

Exa finds the exact content you're looking for on the web using embeddings-based search.

Exa has three core functionalities, surfaced through our API endpoints:

- Search for pages Find any pages on the web using a natural language query. If you still need it, Exa supports also supports Google-style keyword search.

- Get contents from pages Obtain clean, up-to-date, parsed HTML from Exa search results. Contents can be semantically targeted using our 'highlights' feature.

Find similar pages Based on a link, find and return pages that are similar in meaning.

- Exa's precise content retrieval supercharges RAG pipelines, automates hours of research, and creates high-quality datasets for a niche use-case.

Exa is building web-scale systems for search. We routinely run batch jobs with &gt;1000 machines and develop production services that involve many terabytes of text. Up for the challenge?Desired Experience:<ul><li>You have extensive experience with some high performance language (C++, rust, etc.)</li><li>You’re comfortable optimizing the crap out of a system</li><li>Care about the problem of finding high-quality knowledge and recognize how important this is for the world</li></ul>Example Projects:<ul><li>Recreate Google-level search over 10 billion pages in 1 month</li><li>Revamp our document parser to work for any website</li><li>Make a custom vector database run over a billion vectors in under 100ms</li></ul>
