About the Role

Join a small, fast-moving engineering team at a Y Combinator–backed AI voice platform to own projects end-to-end and directly shape the product alongside customers.

What We're Looking For

• 2+ years of professional software engineering experience.

• Strong PostgreSQL experience, including complex queries, performance tuning, and optimization.

• Experience designing scalable backend architectures and making core product and architectural decisions.

• Proficiency with TypeScript, React, Node, and/or Python.

• Experience with scalable async processing or real-time processing systems.

• Experience building products for AI-first or communications-enabled platforms.

• Ability to own projects end-to-end and collaborate closely with customers and cross-functional teams.

• A track record of developing a product from 0 to 1.

• Familiarity with Temporal.io, Twilio, or Modal is a plus.
