Principal Software Engineer – Radar Algorithms Integration

Echodyne Corp • Kirkland, WA

51d • $145,300 - $217,900

About The Position

Radar Reinvented. Echodyne offers the world’s first compact solid-state true beam-steering radar for a wide range of industries and applications. Our high-performance radars work in all weather and are designed for autonomous vehicles, uncrewed aircraft & drones, and security of borders, critical infrastructure, and smart cities. The company combines the patented technology of metamaterials with powerful software to create a radar sensor with unprecedented performance at commercial price points. Echodyne offers its radars to companies working in Automotive, Transportation, Critical Infrastructure Protection, Border Security, Smart Cities, Uncrewed Aircraft Systems (UAS), and Airspace Management including Urban Air Mobility (UTM). Echodyne is seeking a Principal Software Engineer to join our fast-growing team! As the Principal Software Engineer within the Radar Science Dev team, you will bridge the gap between algorithm research and production deployment. You will provide technical leadership on software architecture, code quality, testing, and integration, ensuring that radar algorithms and control software are implemented efficiently and can scale across multiple radar platforms. You will collaborate closely with the internal software and systems teams to design clean interfaces, maintain performance across diverse hardware architectures, and build reusable, well-tested software modules that enable rapid development and reliable operation.

Requirements

• Expert-level proficiency in modern C++ (C++17 or newer), with strong skills in software architecture, modular design, and performance optimization.
• Experience developing and maintaining complex, multi-component systems in C++ and Python.
• Has professional experience with software engineering best practices — including CI/CD, code review processes, automated testing, and version control (Git).
• Strong background implementing algorithms or signal processing logic in production software.
• Experience translating MATLAB/Python prototypes into efficient, maintainable production code.
• Experience designing and implementing software for embedded soft real-time systems.
• Proven ability to work across software, algorithms, and hardware teams to deliver robust integrated systems.
• Strong written and verbal communication skills for technical design and cross-team coordination.
• BS in Computer Science, Electrical Engineering, Physics, or related field with 8+ years of software development experience, or MS with 6+ years, or PhD with 4+ years.

Nice To Haves

• Experience with radar or similar sensing systems (e.g., lidar, sonar, RF systems).
• Proficiency in MATLAB and Rust.
• Familiarity with DSP algorithms (FFTs, filtering, tracking, etc.).
• Familiarity with state machines, control systems, and asynchronous event-driven architectures.
• Understanding of system-level performance tradeoffs (latency, throughput, resource utilization).
• Experience leading or mentoring software engineers or serving as a technical lead.

Responsibilities

• Serve as the software engineering authority within the Radar Science Dev team, establishing and mentoring best practices in software design, code quality, testing, and documentation.
• Architect and implement production-quality software for radar algorithms and control systems in C++.
• Lead effort to refactor and generalize existing radar algorithm and control-loop code so it can support multiple radar platforms with distinct hardware architectures.
• Collaborate with the dedicated internal software and systems teams to define clean interfaces between algorithmic components and radar system infrastructure.
• Translate prototype algorithms (developed in Python/MATLAB) into maintainable, efficient production implementations.
• Design and implement software tests, integration tests, and simulation hooks to validate algorithm behavior.
• Ensure software implementations are modular, reusable, and aligned with long-term maintainability goals.
• Participate in code reviews, design discussions, and technical mentorship across radar algorithm and software teams.
• Contribute to continuous improvement of build pipelines, code reviews, and deployment workflow.

Benefits

• Incentive stock options
• Excellent medical, dental and vision coverage benefits for employee and family members
• Unlimited vacation, 12 paid sick days, and 9 paid holidays
• Company paid disability, life insurance, employee assistance program and travel insurance
• 401k Plan
