Director of Software
SiPhox Health, Cambridge, MA, United States
About SiPhox Health
SiPhox is bringing silicon-photonics diagnostics out of the central lab and into the home. We combine photonics, microfluidics, embedded systems, cloud software, 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 health span.
The Opportunity We’re hiring a
Director of Software
to oversee the software stack across our hardware, cloud services, mobile app, manufacturing, and lab infrastructure. You will provide technical leadership to our team of software and firmware engineers and work closely with other technical leaders to ensure the system meets SiPhox’s customers’ needs.
You will have significant software development experience on multi‑disciplined projects with a major hardware element. You will be comfortable discussing cloud scaling strategies before switching to supporting a processor‑level troubleshooting embedded issue. You will develop software yourself while supporting a high performing team to meet the company’s needs.
This role will require occasional travel to manufacturing sites in the US and internationally. This is an in-person role, including working closely with the hardware team at our lab.

Define and own the SiPhox software system architecture
Develop system and subsystem requirements for developers
Develop software for use in the SiPhox system, covering the hardware, cloud, app, and lab infrastructure
Lead the software verification and validation process to contribute to a Design History File for regulatory submission
Leadership
Lead a team to meet challenging deadlines while maintaining high quality standards and motivating engineers
Provide mentorship and coaching to engineers at different stages of career growth (approximately 6 engineers)
Lead recruitment efforts to fill gaps as required
Manage external vendors and contractors’ software development for SiPhox
Cross-Functional Collaboration
Work closely with other technical leaders and contributors to ensure the software/hardware works together as a system, including contributing to and leading design reviews
Act as a team player first, always willing to work with others to find the right overall approach given the broader constraints
Partner with Quality and Regulatory teams to ensure software development aligns with design history file documentation and QMS requirements
Process & Continuous Improvement
Own and refine development processes, understanding the right level of rigor for different points of the development process
Lead failure investigations, CAPAs, and non-conformance reports as required
Desired Qualifications Must-Have
10+ years of experience creating software for complex products and systems
3+ years of experience leading and managing a team of engineers
Developed software as a medical device (SAMD) for a class 2 or 3 application (IEC 62304 class B or C)
Experience defining technical product architectures across hardware and software
Experience designing and deploying distributed systems on AWS (or GCP/Azure)
Up-to-date with AI coding tools (e.g., Cursor, Claude) and their practical application for software development
Highly capable in modern programming languages, Python, C, C++ etc.
Outcomes-based mindset – able to understand complex problems and find best ways through for the overall system
Strong analytical and troubleshooting skills with a structured approach to root cause analysis
Excellent verbal and written communication in English – able to distill complex technical problems for diverse audiences
Collaborative, low-ego working style; comfortable operating across disciplines and asking good questions
Top-tier work ethic, high standards, and ownership mindset
US work authorization
Bachelor’s or Master’s degree in relevant engineering or science
Able to do occasional travel
Good-to-Have
Delivered IVD (in‑vitro diagnostics) systems through FDA approval and to the market in the US and/or CE marking in Europe
Experience developing for cybersecurity, including threat modeling, SBOM management and section 523B compliance
Experience developing mobile applications for iOS and Android
Experience implementing CI/CD and test automation in regulated environments
Developing fluid handling and/or lab automation systems
Experience with optical or photonic systems
Experience developing firmware in an RTOS and with microprocessors (e.g., STM32)
Why This Role Is Unique You will be part of the team developing a novel product category that will be hugely impactful for millions of customers around the world. This is a highly multi-disciplinary environment, and you’ll work with and learn from teams covering fluidics, optics, mechanics, electronics, biology, and chemistry.
SiPhox is close to submitting its first FDA submission for our system and you will be building the software that takes us through regulatory clearance and as we prepare for commercial launch.
This role is at the heart of what SiPhox is doing and you will have a major impact on the company’s success.
