Résumé du poste

Strativ Group is seeking a hands-on hardware engineer to own a drone platform end to end — from mechanical design to firmware and testing in water.

You will design airframe CAD, integrate electronics, develop embedded firmware in C/C++, and build the software tools used by the workshop and trials, with an emphasis on rapid iteration and manufacturability.

The role offers a fast-paced environment in the Paris area with equity potential and the chance to shape a product from the ground up.

Qualifications

• 5+ years in hardware development with end-to-end product shipping.
• Strong CAD skills and rapid prototyping experience.
• Embedded electronics experience with PCBs and sensor integration.
• Firmware development in C/C++ on microcontrollers.

Responsabilités

• Mechanical design of airframes, CAD, rapid prototyping for manufacturability.
• Electronics: PCB design, sensor integration, power management, motor control.
• Firmware: low-level embedded software for sensors and controls.
• Integration and testing: prototype assembly, pool and sea trials.
• Develop software tools for telemetry, data analysis, and internal tooling.

Description du poste

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.
