Job Description

Your mission

Join our fast-moving stealth startup as an Embedded Hardware Engineer working on next-generation wearable technologies. You’ll take ownership of the electronics stack for our core platform and play a key role in bringing complex embedded systems from prototype to production.

Your profile

Key Responsibilities

Design and bring up embedded PCBs for electromechanical control systems (e.g. pumps, solenoids, pressure sensors).
Develop and validate power systems, including battery integration, charging, PMICs, and power regulation.
Drive component selection with attention to lifecycle status, sourcing risk, and BOM stability.
Collaborate with mechanical and firmware teams on layout, signal integrity, and system interfaces.
Interface with contract manufacturers to ensure DFM/DFA, support builds, and troubleshoot bring-up issues.
Support low-level firmware interfaces (GPIO, I²C, SPI) for device control and sensor feedback.
Conduct feasibility studies and support transition from R&D prototypes to manufacturable hardware.

Required Experience

5+ years in embedded hardware design, with at least 1–2 shipped commercial products.
Strong experience with PCB layout and assembly for compact, mixed-signal systems.
Deep understanding of battery-powered hardware: LiPo, PMICs, current sensing.
Familiarity with Nordic (nRF) and Espressif (ESP32) platforms.
Experience with electromechanical control: pumps, motors, solenoids, pressure sensors.
Confident using oscilloscopes, logic analysers, current probes, and test equipment.
Ability to debug and validate circuits across hardware and firmware boundaries.

Technical Skills

PCB design using Altium or KiCAD
Microcontroller development: ARM Cortex, ESP32, PIC or similar
Low-power system architecture and embedded power management
BLE and wireless communications (Bluetooth Low Energy, Wi-Fi, etc.)
Basic signal/data processing using MATLAB, Python, or similar

Desirable Experience

Exposure to wearable, medical, or biometric devices
Experience with rapid prototyping, flexible PCBs, and short-cycle iteration
Familiarity with component lifecycle management and production transition workflows
Familiarity with certification considerations such as battery safety (UN 38.3, IEC 62133), wireless approvals (CE/FCC), or basic medical device standards (e.g. ISO 13485) is a plus.

Soft Skills

Clear communicator with strong documentation and cross-functional collaboration skills
Detail-oriented, self-directed, and comfortable operating autonomously
Proven ability to manage multiple hardware subsystems and iterate under tight timelines

Why us?

Work at the core of a high-impact wearable product with real-world applications
Help define the hardware stack of a stealth-stage company as an early team member
Competitive early-stage benefits with strong opportunities for long-term growth
