Senior Electric Hardware Engineer

JOB SUMMARY RhythmRx is hiring a Senior Electronic Hardware Engineer to own board-level design and lead a small hardware team across our portfolio of connected medical wearables and vital-sign monitoring devices. The role combines hands-on schematic, PCB layout, and bring-up work with team-leadership responsibilities — mentoring junior engineers, owning design reviews, and coordinating execution from concept through design transfer to production. The ideal candidate has shipped Class II medical wearables, can balance low-noise biopotential signal acquisition, wireless connectivity, low-power architectures, and tight mechanical envelopes — and is comfortable acting as the technical lead for a hardware team in a regulated design environment.

KEY RESPONSIBILITIES • Own schematic design and PCB layout for medical wearables — biopotential AFE front-ends, sensor integration, wireless connectivity, and battery management. • Drive RF, signal-integrity, and power-integrity decisions for HDI multi-layer and rigid-flex boards in compact form factors. • Lead board bring-up, debug, validation, and EMC pre-compliance testing. • Lead and mentor a small team of junior hardware engineers, PCB layout designers, and electronics technicians; own design reviews and technical quality across team output. • Coordinate task allocation, timelines, and deliverables for the hardware team; act as the primary technical interface with cross-functional stakeholders. • Partner with firmware, mechanical, and regulatory teams to align electronics with system and certification requirements. • Document design rationale, support DHF / regulatory submissions, and drive smooth design transfer to manufacturing. REQUIRED SKILLS • B.E. / M.E. in Electronics or Electrical Engineering. • 5–10 years hands-on hardware design, with at least 3 years in medical, wearable, or connected health electronics. • Prior experience leading or mentoring junior engineers; comfort owning design reviews and acting as the technical reference point for a small team (3–6 engineers). • Strong expertise in multi-layer HDI PCB design and rigid-flex; comfortable with blind / buried vias and impedance-controlled stack-ups. • Proven low-noise analog and mixed-signal design — biopotential AFEs (TI ADS129x, AD8232 or equivalent), instrumentation amplifiers, ADCs. • RF layout experience for at least one of: BLE (e.g., Nordic nRF52 / nRF54), cellular IoT modems, GPS / GNSS. • Cortex-M MCUs / SoCs; I²C, SPI, UART, USB protocols. • Low-power design — Li-Po management, fuel gauging, multi-rail regulators, sleep-mode current budgeting. • Altium / Cadence / KiCad; constraint-driven layout. • Bench fluency — scope, spectrum / network analyzer, source meter, JTAG / SWD, biopotential simulators (Fluke ProSim). • Working knowledge of IEC 60601-1, IEC 60601-1-2 (EMC), IPC Class 3, ESD / EOS protection. PREFERRED • Antenna co-design with metal or conductive enclosures. • Track record of building and developing small hardware teams. • Ultra-compact wearable form factors; stacked / flex-rigid PCB design. • Exposure to FDA 510(k) and CE-MDR technical file preparation. • Working knowledge of ISO 14971 (risk management) and IEC 62304 (firmware-adjacent). • Prior involvement in pilot builds, DFM, and design transfer with EMS partners. • Familiarity with applicable IEC 60601-2 series particular standards for the device class. • Cellular IoT certification exposure (PTCRB, GCF, carrier approvals).
