Job description

About SiPhox Health

SiPhox is bringing silicon-photonics diagnostics out of the central lab and into the home. We combine photonics, microfluidics, embedded systems, and semiconductor-grade manufacturing to quantify multiple biomarkers in minutes on a coffee-maker-sized device—aiming to build the first mass‑market photonic blood analyzer to improve chronic disease care and increase human healthspan.

The Opportunity

We’re hiring an Embedded AI Systems Engineer to architect and own the firmware layer that runs the instrument end-to-end: optics, fluidics, thermal control, sensing, motion, safety, and UX. You’ll define the real-time behaviors that make a complex, multi-domain system operate with medical-grade precision and reliability, partnering closely across EE, systems, assay, photonics, fluidics, mechanical, and software.

What You’ll Do

• Build production embedded firmware: HALs, RT state machines, event-driven control, inter-module comms
• Convert system needs into clear, testable requirements and designs
• Implement/optimize machine vision and signal processing for electromechanical accuracy
• Develop bootloaders, calibration flows, diagnostics, and test/fixture firmware
• Lead bring-up to V&V to commercial release, integrating across sensors, motion, fluidics, photonics, and cloud/app
• Own reliability/safety: hazard analysis, FMEA inputs, fault-tolerant behaviors, verification automation and traceability
• Debug complex system issues; optimize timing, control loops, memory, and performance

What We’re Looking For

Must-have

• Strong C/C++ for embedded (drivers, bring-up, real-time control)
• RTOS experience (e.g., FreeRTOS/Zephyr/ThreadX/VxWorks)
• Experience with common MCU families (STM32/ESP32/NXP/Nordic or similar)
• Motion/electromechanical control (steppers/servos, closed‑loop control)
• Proven firmware architecture ownership and excellent cross-disciplinary debugging
• BS in EE/CE/CS (or equivalent), US work authorization, occasional travel (<10%)
• Top‑tier work ethic, high standards, and ownership mindset

Nice-to-have

• Shipped complex electromechanical products end-to-end
• Fluidics / liquid handling automation experience
• Medical device firmware under ISO 13485 / IEC 62304 (Class C preferred) and risk mgmt per ISO 14971
• Calibration/DAQ, wireless connectivity, manufacturing fixtures
• Security/data integrity familiarity (21 CFR Part 11, HIPAA, IEC 80001)

Why This Role Is Unique

You’ll build the firmware foundation for a new category: a consumer‑deployed silicon-photonic diagnostic device that tightly couples optics, fluidics, motion, and sensing—and ships lab‑quality biomarker measurement into millions of homes.

Benefits

• Generous equity compensation
• Luxury gym membership
• Healthcare, dental, 401k, etc.
• Two 1‑week company shutdowns (summer/July 4 and Christmas break) in addition to PTO
