01Key Responsibilities
Technical Ownership & Architecture
- Own the firmware and embedded architecture across Rymo's device portfolio, including microcontroller platforms (nRF52, STM32, and other ARM-based systems).
- Define and enforce coding standards, version control practices, and a repeatable firmware release process, replacing informal or ad hoc practices from earlier stages of the company.
- Evaluate and re-architect legacy or outsourced firmware/electronics where reliability or scalability is at risk.
- Design for BLE communication, sensor integration, motor control, and real-time performance across robotic and rehabilitation devices.
Reliability, Quality & Compliance
- Build and own test frameworks (unit, integration, hardware-in-the-loop) to catch defects before field deployment.
- Ensure firmware and hardware design decisions align with ISO 13485, IEC 60601-1, IEC 62304, and relevant CDSCO/BIS/CE certification requirements.
- Lead root-cause investigations for field issues and translate them into design or process changes.
- Partner with the regulatory/quality team on design history files, risk documentation (ISO 14971), and traceability for audits.
Cross-Functional & Product
- Work directly with mechanical, electronics, software, and clinical/product teams to translate product requirements into buildable, certifiable hardware/firmware.
- Support production, field trials, and post-launch iteration, with an eye toward reducing launch time.
- Contribute technical input to BD, grant, and regulatory submissions where embedded systems detail is required.
Required Skills & Experience
- 69+ years of hands-on embedded systems / firmware engineering experience, with at least 2 years owning architecture or leading a small team.
- Deep expertise in Embedded C/C++, ARM Cortex-M architectures (nRF52, STM32 or equivalent), and RTOS or bare-metal real-time systems.
- Proven experience with BLE communication stacks, peripheral drivers, and hardware debugging (oscilloscopes, logic analyzers, multimeters).
- PCB literacy: able to design, review, and sign off on PCB layouts (Altium, KiCad, or Eagle) and catch issues before fabrication.
- Regulated-hardware background (medical devices, automotive functional safety, or industrial safety) with exposure to IEC 60601, IEC 62304, ISO 13485, ISO 26262, or comparable standards strongly preferred.
- Track record of ownership: someone who has previously inherited an ambiguous or under-resourced system and turned it into something reliable and scalable.
- Communication: able to explain technical trade-offs to non-technical stakeholders (founders, clinical, regulatory) and to give/receive feedback directly and non-defensively.
- Education: Bachelor's or Master's in Electronics, Electronics & Telecommunications, Mechatronics, or a related engineering field.
