This one’s for builders who like their code to touch the real world. You’ll develop firmware + backend systems + tooling for cellular IoT devices, and you’ll actually work hands-on with the hardware (debugging, testing, validating), not just toss code over the fence.
About Cardio Partners
Cardio Partners (a Sarnova company) is a national leader in emergency prevention and sudden cardiac arrest readiness. They provide equipment, consultation, training, and program management, supporting healthcare and emergency response needs.
Schedule
- Remote (U.S. only)
- Must work Eastern Time hours: 8:00am–5:00pm ET
What You’ll Do
- Build and maintain firmware, backend systems, and internal tooling for cellular IoT products
- Develop embedded software in C for STM32 microcontrollers (performance + reliability)
- Integrate embedded AI models to expand device capabilities
- Work directly with physical devices for troubleshooting, debugging, and validation
- Support efficient cellular comms and low-power operations
- Contribute to backend/tooling work in Python and Ruby on Rails
- Collaborate tightly with hardware, electronics, manufacturing teams across the full product cycle
- Track new IoT tech and recommend smart improvements
What You Need
- Bachelor’s degree in Computer Science, Electrical Engineering, or related field
- 7+ years of software development experience, with strong embedded + full stack focus
- Strong C for microcontrollers (STM32 preferred) and cellular communication protocol experience
- Backend experience in Python and Ruby on Rails
- Strong understanding of hardware/software integration and low-power design
- Ability to work independently and lead complex initiatives in a remote setting
- Strong problem-solving and cross-team communication skills
- Big plus: experience integrating AI models into embedded systems
Benefits
- Competitive salary (commensurate with experience)
- Comprehensive benefits package
- 401(k) plan
- Equal Opportunity Employer (EEO/M/F/Veterans/Disabled)
Quick gut-check: this is a legit senior role. If you don’t already have embedded C + microcontroller + cellular experience, it’s going to be a tough sell. If you do have that combo, this could be a strong swing.
