About the role

We're looking for a Senior Product Engineer on our Product Engineering team. You will put companies in physical buildings where they belong. This is a high-ownership role for someone who wants to shape both the technical foundation and the product direction of a company at an early and critical stage.

We care about what you’ve done, not how long you’ve done it for. You will write your own tasks.

What you'll do

  • Drive architecture and technical direction across the full stack, backend, frontend, and data services.
  • Build and ship product features
  • Raise the technical bar for the team through architecture review, code review, and hands-on mentorship
  • Identify and eliminate complexity and technical debt before it becomes a blocker
  • Prototype and evaluate new technologies and make principled decisions about what belongs in the stack

Minimum qualifications

  • Bachelor's degree in Computer Science, a related technical field, or equivalent practical experience
  • Designed & shipped a full-stack application involving heavy data model manipulation in Python or TypeScript.
  • Coordinated queries across disparate data sources with an eye towards speed
  • Designed, built, and maintained data pipelines to unify multiple different data sources, at different frequencies, using a common orchestration tool (e.g., Dagster, Airflow)
  • Built an application that involved multiplayer and/or client-side sync
  • Showed a lot of data on a screen really fast

Preferred qualifications

  • 4+ years of experience with backend development using Python and/or TypeScript
  • 4+ years of experience with relational databases and data modeling, including schema design, normalization, and query optimization in PostgreSQL
  • Experience building or integrating with AI agents, LLM-based workflows, or Model Context Protocol (MCP) tooling
  • Experience working with geospatial data, including storage, querying, or visualization (e.g., PostGIS, GeoJSON, or similar)
  • Familiarity with sync engines or real-time data synchronization patterns (e.g., Zero, ElectricSQL, or similar)
  • Experience defining and driving technical strategy across a small engineering team, including establishing standards, reviewing architecture, and mentoring engineers
  • Experience working in fast-paced, ambiguous environments with a high degree of ownership

About you

You simplify and accelerate by finding the most direct path to a good outcome and ruthlessly cutting what doesn't serve it. You reason from first principles rather than reaching for a playbook, and you have strong enough taste to know what good looks like in code, in product, and in process. You can separate your identity from your work, which means you're willing to throw away something you built if something better exists. You're curious, and you build without waiting for permission.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
