Helix AI Engineer, Backend Infrastructure

Figure AI Figure AI · Robotics · HQ · AI - Helix Team

Backend engineer to build and scale real-time data infrastructure for an AI robotics company, focusing on high-throughput, low-latency streaming of media and sensor data to power AI and robotics platforms. Responsibilities include architecting cloud backend systems, designing data pipelines, owning SLAs, integrating ML model serving, and building observability.

What you'd actually do

  1. Architect and scale cloud backend infrastructure for high-concurrency, real-time streaming of media and sensor data across robot fleets and user sessions.
  2. Design and build low-latency data pipelines that ingest, route, and process high-bandwidth streams — including camera feeds, IMU data, and other robot sensor outputs — into our AI stack in real time.
  3. Own reliability, latency, and throughput SLAs for streaming and data infrastructure.
  4. Collaborate with AI and robotics teams to integrate ML model serving into real-time data pipelines.
  5. Build observability, alerting, and tooling to give the team full situational awareness over live robot traffic.
