Lead Engineer, Perception & Sensor Fusion

Boston, MA | Full-Time

Rilear Industries is a category-defining, defense-forward startup that is establishing persistent underwater autonomy. We are building the underwater infrastructure that untethered assets need to stay down and stay useful.

The battlefield is increasingly moving subsea, and amid rising geopolitical tension, advancing these capabilities has never been more urgent. Our focus is informed by real operating experience in the U.S. Navy, and our co-founding team combines subsea robotics, power systems, and Navy expertise, with backgrounds from Harvard, Carnegie Mellon, and Georgia Tech.

The Role

You will own our underwater perception and sensor-fusion system end to end: from sensor selection through to a calibrated, in-water-validated stack that guides a vehicle into dock at sea.

You will make the architectural calls, integrate the sensors and write the software yourself, take it in the water, find out what broke, and iterate. You will report to our CTO and work closely with our CEO. This is a small team, and your decisions will shape the product and the company.

What You’ll Own

System design

- Architecture end to end: sensor suite, compute, time synchronization, and the fusion pipeline from raw sonar and camera data to relative pose with uncertainty. - Acoustic sensing: detection, ranging, bearing estimation, and tracking from hull-mounted arrays and active transceivers amid multipath, reverberation, and platform noise. - Underwater vision for close-range alignment and docking under changing visibility, lighting, and relative motion. - Calibration, sensor modeling, and the error budget across the full approach envelope.

Integration and proof

- The acoustic-to-optical handoff for rendezvous and terminal docking, including confidence thresholds and behavior on target loss or sensor dropout. - Optical and/or acoustic communications alongside sensing: link budget, timing, and keeping comms from interfering with the acoustic channel. - Test the stack in the lab and in the field.

You Should Have

- Deep expertise in underwater acoustic sensing, including hands-on processing of data from hull-mounted sonar arrays and active sonar transceivers. - Underwater computer vision developed and validated on real underwater data. - Strong fundamentals in sensor fusion and state estimation; practical C++ and Python. -Full-cycle ownership of a robotics sensing system through bring-up, calibration, and in-water testing; strong field instincts. - Willingness to travel for sea trials.

This role requires U.S. person status and is subject to export control requirements. Rilear Industries is an equal opportunity employer.
