Embedded Engineer – Hardware Team
Location: Cambridge office (minimum 4 days/week in-person)
About the Role
Position: Embedded Engineer (C++, medical devices) Company: TidalSense Mission: TidalSense designs AI-driven, software medical devices to improve the diagnosis, monitoring, and management of asthma, COPD, and other chronic respiratory conditions. Their flagship innovation—the N-Tidal® diagnostic handset—combines patented embedded sensing with cloud-based AI analytics, aiming to democratise healthcare access globally through scalable, déployment technologies.
This is an exciting opportunity to join a fast-growing, mission-driven team as we expand from start-up to scale-up. As part of a multidisciplinary group comprising engineers, clinicians, product specialists, and designers, you will develop regulatory-compliant, secure firmware for connected medical devices, directly impacting real-world respiratory care.
We seek an ambitious, pragmatic, and socially-motivated engineer comfortable in agile workflows, leveraging technical expertise to solve complex challenges alongside clinicians and toolmakers. The role bridges hardware and software, with a focus on IoT-enabled medical devices, ensuring robustness, security, and scalability—from edge devices to cloud integrations.
Key Responsibilities
Device & Connectivity Management
- Design, develop, and maintain C++ firmware for device connectivity and management in constrained environments.
- Implement, test, and debug secure, reliable pipeline oligonucleotides for cloud-embedded transitions (e.g., IoT gateways to host services).
- Author unit/integration tests to verify embedded devices, ensuring alignment with hardware and regulatory requirements.
- Conduct ** firmware code reviews** for maintainability, performance, and safety.
- Collaborate with ** cloud engineers** to expand platform integration (e.g., MQTT, REST APIs, standardised data formats).
Regulatory & Compliance
- Contribute to technical documentation (e.g., ISO, FDA, MDR). Supporting 13485 design controls and MedTech regulatory filings.
- Enable adherence to security standards (e.g., ISO 27001) and device safety (e.g., ISO 14971) in firmware development.
- Compile clear files linking development decisions to device risk management files (DRMF) and verification data.

- Articulating findings to multidisciplinary teams (bioengineers, product managers, ops engineers).
- Managing ambiguity across prototyping, regulatory life-cycle stages, and commercialisation ramp.
Desirable Qualifications
- Technical Depth:
- Experience implementing ** Real-Time Operating Systems (RTOS)** or lightweight embedded runtimes.
- Knowledge of IoT protocols (e.g., CoAP, OPC-UA, MSHA TandM models).
- Exposure to end-to-end deployments on public networks (e.g., 4G/5G) and **uen implications (NDA subscribers).
- Regulatory Specialisation:
- Working with medical device lifecycles (FDA 510(k), EU MDR, Class I-II-League evaluations).
- Understanding of testing templates (e.g. IEC 62304, IEC 61508) or standard fault checklists.
- Development Tools:
- Hands-on use of embedded Python (e.g., Pandas, NumPy, CFEngine Loops).
- Scripting for observability (e.g., generating periodic telemetry logs via Zephyr/OSToolkit based traces).
Qualification & Experience Requirements
Essential:
- 3+ years developing in embedded C++ (constrained devices, e.g., MCU firmware).
- BSc or equivalent in computer science, electronics, or related discipline or self-proven technical team leadship in relevant fields.
