About the Role

You'll join a small, product-focused engineering team building the core platform that enables thousands of people to work with AI every day.

What You'll Do

• Build and ship high-quality full-stack features using TypeScript and React, with a strong focus on user experience.
• Design and implement robust backend systems capable of handling massive data volumes and millions of API requests.
• Take end-to-end ownership of features from concept and deployment through to ongoing operation, ensuring reliability and security.
• Debug production incidents, identify root causes, and implement lasting solutions.
• Synchronize and index large client datasets while managing fine-grained permissions.
• Operate and optimize systems that process millions of LLM calls per month.
• Architect and scale environments that spawn thousands of secure code sandboxes daily.
• Build base infrastructure to help the integrations team onboard new systems quickly.
• Mentor junior engineers and raise the bar through thorough, constructive code reviews.

What We're Looking For

• 3 or more years of professional software engineering experience, ideally in the 3 to 5 year range.
• Proven production experience with React, TypeScript, and PostgreSQL.
• Strong backend skills at scale, including Python, tRPC, or comparable technologies.
• Hands-on experience with Docker, Kubernetes, CI/CD, and high-throughput distributed services.
• Demonstrated full-stack application development, including clearly owned frontend projects.
• Experience building scalable, secure, and reliable backend services handling high data or API volumes.
• Strong product ownership with attention to UX and long-term product quality.
