Role at a glance
We are hiring a Senior Full Stack Software Engineer on a full-time basis. This role is fully remote and open to candidates located anywhere.
Your impact
- Ship full-stack features end-to-end as part of a small pod, taking ownership from problem definition through production using Node.js, React, Golang, MongoDB, Elasticsearch, and AWS.
- Design and build APIs, front-end interfaces, and AI-powered capabilities that improve customer experience and platform efficiency while maintaining data integrity and security.
- Optimize performance, write thorough tests, conduct code reviews, and share on-call responsibilities to keep quality high across the codebase.
What you'll need
You bring seven or more years of progressive software development experience along with a bachelor's degree in computer science, software engineering, or a related field. You're comfortable working across the stack and can follow the work wherever it leads, whether that's frontend, backend, or infrastructure on AWS. You understand systems at depth, including data structures, algorithms, concurrency, distributed systems, API design, and database internals. You ramp quickly on unfamiliar code, use modern AI developer tools such as GitHub Copilot, Cursor, or Claude Code as a daily force multiplier, and own outcomes from design through production. Strong communication, technical judgment, and genuine curiosity about how AI intersects with product and engineering are essential. English fluency is required.
Perks and compensation
We offer competitive salaries, stock options, 100% healthcare coverage, a 401k, WiFi and mobile reimbursement, and a generous vacation policy for U.S. team members. UK team members receive a pension, supplemental health insurance, and additional perks. All roles may involve handling sensitive personal data, and we maintain a remote-friendly culture with an annual in-person gathering.
