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.

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.

REQUIRED SKILLS / EXPERIENCE

  • 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.

DESIRED SKILLS / EXPERIENCE 
(Looking for one or more as a complement to the core skills)
 

  • 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.

QUALIFICATIONS

•    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.
