About the role

Hardware Engineer at Relari focused on building the physical systems behind research, including wearable EMG and sensing hardware, embedded electronics, and integration with external design/fabrication partners. On-site in San Francisco, full-time.

Responsibilities

  • Design and iterate on wearable EMG systems, force sensors, tactile sensors, and supporting electronics.
  • Develop embedded firmware, data acquisition, synchronization, and calibration tooling for multimodal experiments.
  • Rapidly design, fabricate, and iterate on wearables, sensor mounts, enclosures, fixtures, and test rigs using CAD, 3D printing, basic machining, and off-the-shelf components.
  • Own the technical relationship with external design, fabrication, and manufacturing vendors, including design reviews, documentation, DFM, prototype builds, and validation.
  • Select, purchase, bring up, calibrate, and maintain robot arms, hands, sensors, and laboratory equipment.
  • Validate signal integrity, noise performance, durability, safety, manufacturability, and repeatability through structured testing.
  • Work directly with biomechanics and robot-learning researchers to turn experimental needs into usable hardware.

Qualifications

  • Strong fundamentals in electrical, embedded, mechanical, mechatronics, or robotics engineering.
  • Experience taking electromechanical hardware from schematic or CAD through fabrication, assembly, bring-up, testing, and iteration.
  • Comfort with rapid prototyping methods such as CAD, 3D printing, basic machining, and practical shop tools; deep mechanical specialization is not required.
  • Practical understanding of analog signals, grounding, noise, sensor interfaces, and data acquisition.
  • Experience with embedded firmware and comfort working in Python and C or C++.
  • Experience working with fabrication vendors or contract manufacturers; ability to translate prototypes into documented, repeatable builds.
  • A build-first mindset and comfort moving across electronics, mechanics, sensors, and robot integration.
