 Our Operating Principles
 
 
 
 
 
 Extreme Ownership
 
 
 
 
 We take full responsibility for our work, outcomes, and team success. No excuses, no blame-shifting &mdash; if something needs fixing, we own it and make it better. This means stepping up, even when it&rsquo;s not &ldquo;your job.&rdquo; If a ball is dropped, we pick it up. If a customer is unhappy, we fix it. If a process is broken, we redesign it. We don&rsquo;t wait for someone else to solve it &mdash; we lead with accountability and expect the same from those around us.
 
 
 
 
 Craftsmanship
 
 
 
 
 Putting care and intention into every task, striving for excellence, and taking deep ownership of the quality and outcome of your work. Craftsmanship means never settling for &ldquo;just fine.&rdquo; We sweat the details because details compound. Whether it&rsquo;s a product feature, an internal doc, or a sales call &mdash; we treat it as a reflection of our standards. We aim to deliver jaw-dropping customer experiences by being curious, meticulous, and proud of what we build &mdash; even when nobody&rsquo;s watching.
 
 
 
 
 We are &ldquo;majos&rdquo;
 
 
 
 
 Be friendly &amp; have fun with your coworkers. Always be genuine &amp; honest, but kind. &ldquo;Majo&rdquo; is our way of saying: be a good human. Be approachable, helpful, and warm. We&rsquo;re building something ambitious, and it&rsquo;s easier (and more fun) when we enjoy the ride together. We give feedback with kindness, challenge each other with respect, and celebrate wins together without ego.
 
 
 
 
 Urgency with Focus
 
 
 
 
 Create the highest impact in the shortest amount of time. Move fast, but in the right direction. We operate with speed because time is our most limited resource. But speed without focus is chaos. We prioritize ruthlessly, act decisively, and stay aligned. We aim for high leverage: the biggest results from the simplest, smartest actions. We&rsquo;re running a high-speed marathon &mdash; not a sprint with no strategy.
 
 
 
 
 Talent Density and Meritocracy
 
 
 
 
 Hire only people who can raise the average; &lsquo;exceptional performance is the passing grade.&rsquo; Ability trumps seniority. We believe the best teams are built on talent density &mdash; every hire should raise the bar. We reward contribution, not titles or tenure. We give ownership to those who earn it, and we all hold each other to a high standard. A-players want to work with other A-players &mdash; that&rsquo;s how we win.
 
 
 
 
 First-Principles Thinking
 
 
 
 
 Strip a problem to physics-level facts, ignore industry dogma, rebuild the solution from scratch. We don&rsquo;t copy-paste solutions. We go back to basics, ask why things are the way they are, and rebuild from the ground up if needed. This mindset pushes us to innovate, challenge stale assumptions, and move faster than incumbents. It&rsquo;s how we build what others think is impossible

Pylon

<div>About Pylon
America&rsquo;s $13T mortgage market is one of the most important financial systems in the world. It underwrites the middle class and is the mechanism through which millions of families build wealth. But while every other financial instrument has been simplified to an API call, mortgages are still assembled by hand.
We started from zero and created the first vertically integrated mortgage platform that turns origination into a single API.
Publicly traded companies and the country&rsquo;s largest originators are already building on Pylon. Revenue is compounding monthly. We&rsquo;re backed by Peter Thiel, Conversion Capital, QED, Citi, Fifth Wall, and the founders of Ramp, Blend, and Mercury.
Working at Pylon isn&rsquo;t for those seeking comfort. The people who thrive here have high agency, strong opinions, and a track record of delivering outcomes without direction. Many of us are former founders. We move quickly, challenge each other directly, and take full ownership of results. It&rsquo;s hard work, but it will be worth it.
Join us in building America&rsquo;s mortgage rails.<h2 class="jobSectionHeader">
The Team</h2>
We're looking for Back End Engineers to join our Integrations team. This team connects Pylon to the outside world &mdash; the partners, services, and data sources that make a seamless mortgage experience possible.
We have a critical, multi-month project ahead: building out a ton of integrations. Credit bureaus, title companies, insurance providers, document services &mdash; mortgage touches everything, and we need to plug into all of it. This is a rare opportunity to work across the entire mortgage domain and understand how all the pieces fit together, fast.<h2 class="jobSectionHeader">
Here Is What You'll Do</h2><ul><li>
Build integrations across the mortgage ecosystem. You'll connect Pylon to external partners &mdash; each with their own APIs, data formats, quirks, and reliability characteristics. No two are the same.</li><li>
Work on everything. This role touches every part of the mortgage process. You'll gain a comprehensive understanding of how mortgage works &mdash; not in theory, but by building the connective tissue that makes it function.</li><li>
Own solutions from development to deploy to maintenance. You build it, you ship it, you keep it running. Integrations are only as good as their uptime, and that's your responsibility.</li><li>
Be self-directed and versatile. The integrations surface is wide. You'll need to context-switch between partners, prioritize what matters, and drive projects forward without waiting for someone to hand you the next task.</li><li>
Move fast on a high-impact project. This isn't a &quot;someday&quot; initiative. We're building these integrations now, and each one we ship unlocks new capabilities for our customers.</li></ul><h2 class="jobSectionHeader">
Tech Stack</h2><ul><li>

NestJS + GraphQL</li><li>

Temporal.io (workflow orchestration)</li><li>
External partner APIs (REST, SOAP, file-based &mdash; the full spectrum)</li><li>

Publicly traded companies and the country&rsquo;s largest originators are already building on Pylon. Revenue is compounding monthly. We&rsquo;re backed by Peter Thiel, Conversion Capital, QED, Citi, Fifth Wall, and the founders of Ramp, Blend, and Mercury.
Working at Pylon isn&rsquo;t for those seeking comfort. The people who thrive here have high agency, strong opinions, and a track record of delivering outcomes without direction. Many of us are former founders. We move quickly, challenge each other directly, and take full ownership of results. It&rsquo;s hard work, but it will be worth it.
Join us in building America&rsquo;s mortgage rails.<h2 class="jobSectionHeader">
The Team</h2>
We're looking for Back End Engineers to join our API team. We treat our GraphQL API as a product &mdash; because it is one. Multiple customers build directly on top of it, and the quality of their experience is determined by how well we design, document, and maintain it.
Mortgage is a surprisingly rich domain to model. It's path-dependent: the choices you make early in a loan constrain what's possible later. It's nonlinear: different borrower situations branch into wildly different flows. Most APIs in this space paper over that complexity. We're building one that embraces it &mdash; encoding the real shape of mortgage into a surface that's impossible to misuse and delightful to build against.<h2 class="jobSectionHeader">
Here Is What You'll Do</h2><ul><li>
Define what a mortgage is in code. Seriously. You'll work on semantic models that don't just represent mortgages as they exist today &mdash; they expand what a mortgage can be. This is product design at the API layer.</li><li>
Build toward an event-driven API. We're moving to a world where our API doesn't just respond to requests &mdash; it tells you what happened, why, and what you can do next. You'll help design and ship that future.</li><li>
Make the complex feel simple. Our API should make the mortgage process impossible to get wrong. That means thoughtful abstractions, clear documentation, and an obsessive focus on developer experience.</li><li>
Design for nonlinearity. Mortgage flows aren't linear wizards. Our future API encodes choice, branching, and path-dependence natively. You'll work on guided experiences that model real-world complexity without exposing it as chaos.</li><li>
Treat this as a product surface. You'll think about breaking changes, versioning, onboarding, and the full lifecycle of an API that real companies depend on.</li></ul><h2 class="jobSectionHeader">
