AI Embedded Systems Engineer
About the role
+++ 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 + signal processing for electromechanical accuracy
- Develop bootloaders, calibration flows, diagnostics, and test/fixture firmware
- Lead bring-up → V&V → commercial release, integrating across sensors, motion, fluidics, photonics, and cloud/app
- Own reliability/safety: hazard analysis, FMEA inputs, fault-tolerant behaviors, verification automation + 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 + 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 addattion to PTO
