Open Source Engineer

Description

The company is looking for a high-agency engineer to own our open source work. It extends to the context primitives we're open sourcing now, starting with anydoc, our document parsing engine. You'll keep the core repo healthy and growing, build out the primitives, and think about what makes each one spread on its own.

This is not a developer relations role. We want an engineer who ships the code, reviews the PRs, and makes the repos better every week. Community instincts help, but engineering quality, shipping velocity, and a track record of work people actually use matter most.

Salary Range: $235,000–$260,000 USD/year (SF) / $217,000–$233,000 CAD/year (Toronto)

Equity Range: Competitive equity. Details shared during the process.

Location: San Francisco, CA (SF HQ) or Toronto, ON (Toronto Hub). Hybrid, onsite 3+ days a week.

Job Type: Full-Time

Experience: 5+ years

Work Authorization: Must be authorized to work in the United States or Canada. We're not able to sponsor US visas right now. For Canada, we'll consider sponsorship on a case-by-case basis through our Toronto Hub.

About the company

The company is the easiest way to turn the web into data AI agents can use. One API call converts any URL into clean, LLM-ready markdown or structured data. It's the boring-hard problem everyone building with LLMs eventually hits, solved.

We hit 8 figures in ARR in year one and more than doubled it in year two. Growth like this is rare, and we're just getting started.

We're a small team punching far above our weight. Everyone here owns a real piece of the product and company, end to end, and runs it themselves. No hiding behind process or headcount.

This is a place for people who want to work at the frontier: an AI company building the infrastructure other AI companies run on, not one bolting AI onto an existing product. We move fast, go deep, and are building the tools superintelligence will rely on to gather data from the web. That library is called Alexandria, and it starts now.

Responsibilities

• Own the main the company repo end to end: triage issues, review PRs, cut releases, write docs
• Keep the self-host experience easy: clone it, run it, keep it running, no surprises
• Build out new context primitives, starting with anydoc, our document parsing engine
• Make the calls on scope and API design for what belongs in a primitive and what doesn't
• Think about what makes an open source project spread on its own, and build toward that
• Ship code and review PRs every week. This is an engineering seat, not a community seat

Requirements

• A real open source track record: maintaining a popular repo, or landing significant contributions to one
• You care about the self-host experience and know what makes a repo easy to clone, run, and keep running
• Comfortable owning a repo end to end, from triaging issues and reviewing PRs to cutting releases and writing docs
• You've built parsers, crawlers, browser tooling, or developer libraries, and have taste in what belongs in a primitive and what doesn't
• You understand how open source turns into adoption and pay attention to why some projects take off
• High agency. Happy to make calls on scope, API design, and what gets merged
• Often a maintainer, ex-founder, early startup engineer, or builder with impressive public work
• What We're NOT Looking For
• Someone looking for a developer relations role. This is an engineering seat first
• Someone who wants community work to substitute for shipping code
• Someone who needs a mapped-out roadmap before they'll make a scope call
• Someone who's used open source but never maintained or owned a repo of real scale
• A Note On Pace
• We operate at an absurd level of urgency because the window for what we're building won't stay open forever. If that excites you, keep reading. If it doesn't, no hard feelings, but this role probably isn't for you.

• Technical Chat (~45 min): We'll walk through a repo you've maintained and a real problem from ours: a self-host path that's gotten fragile, a scope call on what belongs in a primitive, or a PR queue that's outgrown one reviewer. Come ready to think out loud. We care how you reason about maintainership, not whether you know our codebase yet.
• Founder Chat (~25 min): Culture, pace, ownership, and how you like to work. Time for your questions too.
• Paid Work Trial (~40 Hours): Ship something real on one of our open source repos, paid at a contractor rate. It's the truest signal for both sides. You see what maintaining the company's open source work actually feels like, and we see how you operate. Remote-friendly, and we'll flex around your current commitments.

• Experience: Any (new grads ok)
