Roboticist, Physical AI at Sieve · LumiJobs

Responsibilities

As Sieve's first roboticist, you'll own the physical side of our physical AI data: the robots, capture rigs, and teleoperation stations that generate the datasets we deliver to frontier labs. You'll take each system from parts on a table to a setup that records clean, synchronized data at a partner site, and you'll handle both the hardware and the software along the way.
Most of your week will be spent with real equipment: wiring and rewiring, bringing up new sensors, chasing calibration drift, and fixing whatever stopped recording overnight. We want someone who has run systems in real deployments and brings discipline to the work. When a rig works once, you want to know why, and you want it to work the same way at every site. You don't consider a problem closed until the data coming off the system is right.
Capture rigs: Design and bring up the hardware we record with: multi-camera arrays, head- and wrist-mounted egocentric cameras, depth/IMU/force sensor packages, and teleoperation stations such as leader-follower arms.
Calibration and time sync: Own camera intrinsics and extrinsics, hardware triggering, and clock alignment across cameras, IMUs, and encoders. If the streams don't line up, the dataset isn't usable.
Root-cause failures: When a motor stalls, a camera drops frames, a power rail sags, or a bus goes quiet, find the actual cause and fix it so it stays fixed.
Field deployments: Set up and operate systems at partner sites. Build them to survive daily use, to be run by operators without robotics backgrounds, and to be repaired quickly on site.
Robot and capture software: Write and maintain drivers, ROS/ROS2 integration, recording and logging, and QA checks that run at capture time and hand data straight to Sieve's pipelines.
Repeatable builds: Produce BOMs, assembly docs, validation plans, and SOPs so we can stand up the same setup at the next ten sites without you there.
Team foundations: As the first hire in this area, set the hardware architecture, interfaces, test standards, and engineering culture for the physical AI team.
