Job summary

Echodyne is hiring a Principal Software Engineer to help build our next-generation radar software platform for defense and automotive applications. You’ll architect robust solutions, collaborate across engineering, product, and UX, and ensure our technology performs in real-world environments.

Join a team delivering async backend services, real-time data models, and well-defined APIs, while advancing prototypes to production with strong observability and security.

Qualifications

• 7+ years building customer-facing, production-grade software systems.
• Modern full-stack expertise: React 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.
• 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.
• Familiar with CI/CD practices, observability, and resilient system patterns.
• B.S. in Computer Science or equivalent industry experience

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.
