Summary
Develop embedded C++ flight software and radar system integration for next-generation aviation safety technology. Focus on numerical optimization, networking, and FPGA interfaces within a DO-178C environment.
Job description
We're building safety-enhancing technology for aviation that will save lives. Automated aviation systems will enable a future where air transportation is safer, more convenient and fundamentally transformative to the way goods — and eventually people — move around the planet. We are a team of mission-driven engineers with experience across aerospace, robotics and self-driving cars working to make this future a reality.
As a Sr. Embedded Software Engineer, Radar at Reliable Robotics, you will be a part of the Embedded Systems team developing the embedded software for our next-generation Radar system. Phased array radar systems have historically been reserved for specialized applications, but we’re making this technology affordable to enable Detect and Avoid for widespread commercial applications. Your contributions will directly enable aircraft product demonstrations, unlock the development of higher-level capabilities, and set the stage for product certification, and delivery to market.
Responsibilities
- Develop C++ flight software requirements, design, code, unit tests, and requirements-based test cases in accordance with DO-178C software development procedures
- Develop Python-based software integration test cases
- Focus areas include, numerical optimization, networking, protocol drivers, memory interfaces, and software-to-FPGA interface layer
Basic Success Criteria
- 8+ years of experience developing C or C++
- 3+ years of experience translating/optimizing complex mathematical algorithms into performant, deterministic embedded code
- Hands-on experience developing driver-level software for software-to-FPGA interfaces and managing high-bandwidth data pipelines
- Bachelor’s degree in Computer Science, Computer Engineering, or equivalent experience
Preferred Criteria
- 12+ years of professional experience developing C or C++
- Hands-on experience with Radar algorithms, radar signal processing, integration, and test of a radar system
- Experience working in a DO-178 software development environment
- Thorough understanding of computer architecture, operating systems, and networking
- Comfortable with a fast-paced, agile/iterative development life cycle
