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).
