Staff Backend Engineer

The Role

We're looking for a staff engineer to help shape the technical direction of our backend systems. You'll lead complex projects, make architectural decisions that affect the whole platform, and raise the bar for engineering quality across the team. This is a role for someone who wants to build, not just advise. You'll write code, own systems, and ship, but you'll also be expected to think beyond your immediate work to identify what the team should be building next and how we should build it.

What You'll Work On

• System architecture: Designing how our agent infrastructure should evolve as we scale, making tradeoffs between speed, reliability, and complexity
• Hard technical problems: Owning the most ambiguous, highest-stakes projects where getting it wrong would hurt the business
• Technical strategy: Identifying gaps in our systems before they become problems and building the case for addressing them
• Engineering quality: Setting standards for code review, system design, and operational excellence through your own work

Tech Stack

• Backend: Python (Django/FastAPI), TypeScript (Node.js)
• Infrastructure: AWS, Modal, Kubernetes, Postgres
• Frontend: TypeScript, Next.js (you'll interact with this when needed)

You Might Be a Fit

• 7+ years of backend engineering experience, with a track record of leading complex projects
• Opinions about how systems should be built, and can articulate the tradeoffs behind those opinions
• Write excellent code and hold others to a high standard without being a bottleneck
• Are energized by hard problems and comfortable with uncertainty
• Want to be hands-on at a company where staff engineers ship code, not just review it
• Built systems that scaled and understand what breaks at each order of magnitude

Perks & Benefits

• Competitive base + bonus + equity
• Catered lunch daily
• Dinner stipend $500/month
• Wellness & commuter benefit (gym, fitness classes, mental health)
• 401(k) plan
• Medical, dental, and vision coverage
