We are looking for an embedded software engineer to join the IoT group that builds the software for the microcontroller-based sensor hardware designed and manufactured in-house. Our products offer an interesting engineering challenge: microcontrollers with just a few hundred kilobytes of RAM and code space must collect data from sensors such as accelerometers and GPS, communicate with back-end systems over the Internet and nearby devices with Bluetooth, perform over-the-air upgrades with new firmware, and manage cryptographically-secured storage – all while using so little power that they can run for years on a battery. 

CMT is looking for a Senior Embedded Software Engineer to help us change the world. CMT has helped protect over 65 million drivers and prevent over 126,000 crashes worldwide. We build AI to solve some of the most difficult challenges in mobility — understanding and reducing risk, detecting crashes, and getting people life-saving help. The problems are hard. The impact is real. No matter your role, your work will matter at CMT.

Responsibilities: 

• You will be collaborating with colleagues in the firmware group as we build new features and entirely new products together: deciding on the right software architecture, writing code and tests, measuring key metrics such as power use, and keeping the codebase healthy in the face of increasing complexity. You will participate in the entire design process as our software group negotiates with product managers and hardware engineers to find the intersection between what’s technically feasible and what customers want. 
• Complete any additional tasks as they arise 

Qualifications: 

• Bachelor’s degree or equivalent years of experience and/or certification in a related field 
• 4+ years of relevant professional work experience

• Comfortable with the Linux command-line 
• Comfortable with git 
• Track record of writing clean, readable, testable code 
• Be nice. We’re nice, and it’s not fun to work with people who aren’t 
• Have a “leave things better than you found them” philosophy. For example: If you’re adding a new feature and discover that it would be cleaner to refactor some code first, do the refactor
• Good engineering taste: for example, finding the right balance of spending time on code health vs. making forward progress on new features in the face of deadline pressure

Nice to Haves:

• Build and maintain proxy and augmentation layers that integrate domain services from across the organization (such as video infrastructure, recommendations systems, and search) into a cohesive, unified API.
• Drive continuous improvements to the reliability, performance, scalability, and maintainability of Philo's product API infrastructure, ensuring sub-second response times and high availability across all endpoints.
• Collaborate with data science and product analytics teams to instrument the API layer for experimentation, A/B testing, and feature rollouts, enabling data-driven product decisions.
• Build and enhance observability tools to proactively monitor API performance, identify bottlenecks, debug issues, and ensure optimal cache utilization across the system.
• Work with infrastructure teams to optimize database queries, implement effective caching strategies, and ensure DataServer scales efficiently as Philo's user base grows.

Qualifications

• 8+ years of software development experience.
• 2+ years of experience mentoring and providing technical guidance to other engineers (bonus points for experience or interest in managing engineering teams).
• Strong experience designing and implementing GraphQL APIs at scale (bonus points for experience with complex schema design, query optimization, and federation patterns).
• Proven track record of building highly efficient and highly available backend services using NodeJS, Ruby, Golang, Python, or similar programming languages.
• Experience operating in cloud computing environments using modern software deployment technologies (e.g. Docker, Kubernetes, AWS).
• Deep understanding of API design principles, RESTful and GraphQL patterns, caching strategies, and performance optimization techniques.
• Experience working with large amounts of data and making data-based decisions to prioritize projects, including familiarity with relational and non-relational databases and modern data warehousing and querying with SQL.
• Strong systems thinking with the ability to design cohesive API abstractions that cleanly separate concerns while enabling flexibility for diverse client needs.
• Experience building proxy and aggregation layers that integrate multiple backend services into unified APIs.
• Familiarity with experimentation frameworks, feature flag systems, and A/B testing infrastructure.
