Staff Full Stack Engineer

As a Staff Full Stack Engineer, you will own technical decision-making and ship products end to end across the stack. You will build the platforms that power the next generation of audio AI for the world's leading AI labs and enterprises, working shoulder to shoulder with research engineers on data collection, curation, and iteration. This is a high-autonomy role for an engineer who is comfortable making consequential calls quickly and with incomplete information. Reporting to [Head of Engineering], you will also help set technical standards and mentor engineers as the team scales.

Key Responsibilities
• Own and drive 0-to-1 product development across the full stack, from problem definition through production launch and iteration.
• Make key technical decisions with speed and limited data, balancing long-term architecture against startup delivery pressure.
• Design and build scalable systems that ingest, process, and serve terabytes of audio data reliably.
• Build and maintain customer-facing web applications and internal tooling using Next.js, TypeScript, and TailwindCSS.
• Develop backend services and data models with Node.js, tRPC, and PostgreSQL on AWS infrastructure.
• Build real-time and batch audio processing pipelines using WebRTC, FFmpeg, and Python.
• Collaborate closely with research engineers on data collection, annotation, and model iteration workflows.
• Mentor junior engineers, lead code and design reviews, and set technical standards as the team grows.
• Ship to production daily, taking ownership of the quality, reliability, and observability of what you build.
