Echodyne is seeking a Principal Software Engineer to help build its next-generation radar software platform advancing mission-critical security for defense and automotive applications.

Requirements

  • 7+ years building customer-facing, production-grade software systems.
  • Modern full-stack expertise: React (or equivalent) front-ends and async backend services (Tokio/Rust or similar).
  • Strong experience with modular architectures, documented API contracts, and robust service lifecycles.
  • Designed for real-world constraints: field/defense/automotive deployments or similar high-stakes, performance-critical systems.
  • Hands-on with Python and/or Rust and/or C/C++ for practical, scalable solutions.
  • Familiar with CI/CD practices, observability, and resilient system patterns.

Responsibilities

  • Deliver core platform components: async (Tokio/Rust) backend services, well-defined APIs, and real-time data/event models.
  • Partner closely with React/front-end teams to enable shared components, efficient state management, and system health visualizations.
  • Advance prototypes to production: transform algorithms or domain logic into well-tested, high-performance endpoints with solid observability.
  • Architect for resilience: address intermittent connectivity, graceful degradation, security hardening, and offline scenarios.
  • Drive quality and velocity: refine CI/CD, improve testing (performance, contract/property), and establish clear instrumentation and SLO/error budgets.
  • Mentor and influence: facilitate clear design narratives, code reviews, and integrate product and field feedback into the development lifecycle.

Other

  • Skilled collaborator with product, UX, and technical experts; strong communication in cross-functional contexts.
  • Track record mentoring peers and driving technical excellence without direct authority.
  • B.S. in Computer Science or equivalent industry experience
  • Echodyne’s technology is export controlled by the U.S. Government and we must evaluate an applicant’s eligibility to handle export-controlled information or obtain required Government authorizations. Therefore, we will ask you as part of the application process to identify whether you are a U.S. Citizen or green card holder, or have asylum/refugee status in the U.S.
