You will own the physical drone: mechanics, electronics, firmware, integration, all the way to a swimming prototype, plus the software tools that run the workshop and the trials. A rare role for someone who loves the machine shop and the soldering iron as much as the code.

What you will do

  • Mechanical design: CAD of the airframe (hydrodynamic hull, high-pressure sealing), rapid prototyping (3D printing, machining), iterating toward a design manufacturable at scale.
  • Electronics: PCB design, sensor integration (IMU, sonar, camera, pressure), power management, and low-signature electric propulsion.
  • Firmware: low-level embedded software (drivers, sensor buses, motor control, RF telemetry).
  • Integration & testing: prototype assembly, test benches, pool then sea trial campaigns.
  • Software tools: telemetry dashboards, trial-data analysis scripts, internal tooling, in Python / web. Here, AI assistants are an integral part of how we work.

What we are looking for

  • 5+ years in hardware development, with at least one complex physical product designed and shipped end to end (drone, robot, embedded device…).
  • Strong mechanical CAD (SolidWorks, Fusion 360, or equivalent) and rapid prototyping.
  • Solid embedded electronics experience: designing or modifying PCBs, oscilloscope debugging, sensor integration.
  • Firmware in C/C++ on microcontrollers (STM32, ESP32, or equivalent).
  • Comfortable with Python and web development for internal tools.
  • Pragmatic and fast: you would rather have a drone swimming this week than a perfect design next month.

Nice to have

  • Maritime or subsea experience: sealing, corrosion, acoustics, hydrodynamics.
  • Defense, aerospace, or automotive background (reliability and cost constraints).
  • Design-for-manufacturing (DFM) experience. Battery systems and their integration.
  • From CAD to the sea: you design, build, and test the whole drone, not a sub-part of a subsystem.
  • Direct impact: small founding team, you are one of the first engineers, and your technical choices become the product's architecture.
  • Speed: hardware iterations in weeks, regular sea trials.
  • Team: founders trained at ENS, MIT, and NASA.
  • Package: competitive salary + meaningful early-stage equity.
