Overview

Staff Engineer (Full stack)

Responsibilities

• Own a system or area of the product end to end, including the messy, ambiguous parts that do not come with clear instructions.
• Make sound design and technical decisions within your domain, and explain and defend the trade-offs.
• Take vague business or product requirements, shape them into a clear technical plan, and execute.
• Care about how your systems behave in production: correctness, performance, and maintainability over time.
• Raise the level of the engineers around you through how you build, review, and think, without managing them.
• 6 to 11 years of professional software engineering experience.
• A track record of owning projects or systems that span multiple components, not just building individual features inside someone else's design.
• Deep, hands-on strength across most of the stack:
• Frontend: strong understanding of how the browser works (rendering, the DOM, the event loop, networking, performance).
• Backend: strong command of a language such as Python or Java, with solid experience in API design, authentication, and third-party integrations.
• Deployment: comfortable deploying and operating systems, on a VPS or via orchestration such as ECS or Kubernetes.
• Data: experience with data warehouses and data at scale.
• ML and LLMs: a solid grasp of core ML concepts and hands-on experience building with LLM APIs, including their parameters and failure modes.
• Ownership and judgment: you take responsibility for outcomes, make sound calls under ambiguity, and make the team better.
• The mindset we value across the whole team: data-driven, questioning, strong opinions held loosely, a fast and deep learner, a sense of urgency, and clear communication.

Qualifications

• How our process works
• Our hiring is work-first. If you progress, you will complete a practical task and then discuss it with us in depth, including your design and technical decisions, so we can see how you actually think and build. Using AI tools is welcome throughout, as long as you understand and can explain everything you produce.
