Senior Software Engineer, ML Infrastructure

SKILLS AND REQUIREMENTS

• No single person will have depth in everything below. We are looking for someone who has built platform services in production at scale with real depth in at least one of three areas — large-scale data pipelines , annotation and labeling , or evaluation and simulation — plus solid cloud and Python across the board:
• A builder at scale: a track record of designing and shipping production systems and services that other teams depend on daily.
• Deep hands-on experience with large-scale data pipelines for ML: multi-terabyte transformation and dataset assembly of multimodal sensor data — video and image streams, time-synchronized robot telemetry, the kind of data that trains vision-language-action and computer-vision models — with columnar and time-series formats (Parquet, Arrow), dataset versioning and lineage (lakeFS, DVC, Iceberg, or equivalent), and object storage (S3, MinIO).
• Experience with ML annotation and labeling at scale: automatic annotation of data combined with human-in-the-loop workflows — the tooling, quality control, and throughput management.
• Experience building large-scale evaluation or simulation harnesses: many parallel jobs on GPU infrastructure, aggregated into decision-grade results.
• Strong Python and general software engineering ability (testing, API design, code review), plus cloud infrastructure, Kubernetes, Docker, and modern CI/CD.

EDUCATION and/or EXPERIENCE

Bonus Qualifications

• Robotics data formats and fleet-scale telemetry (MCAP, ROS, LeRobot, or equivalent).
• Simulation-in-the-loop evaluation with Isaac Sim, IsaacLab, MuJoCo, or equivalent.
• Reinforcement or imitation learning infrastructure for embodied agents (rollout workers, sim-eval harnesses).
• Deploying ML models to edge targets (ONNX Runtime, TensorRT, robot fleets).

PHYSICAL REQUIREMENTS

• Prolonged periods of sitting at a desk and working on a computer
• Must be able to lift 15 pounds at times
• Vision to read printed materials and a computer screen
• Hearing and speech to communicate
• *This is a direct hire. Please, no outside Agency solicitations.
