Role summary

Echodyne is seeking a Principal Software Engineer to help build its next-generation radar software platform for defense and automotive applications. This role involves architecting robust solutions, collaborating across engineering, product, and UX, and ensuring technology thrives in dynamic environments. Responsibilities include delivering core platform components like async backend services (Tokio/Rust) and APIs, partnering with front-end teams (React), transforming algorithms into production-ready endpoints, architecting for resilience against connectivity issues and security threats, and driving quality through CI/CD and testing. The role also requires mentoring peers and influencing technical direction without direct authority.

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).

ROLE OVERVIEW

Echodyne is seeking a Principal Software Engineer to help build our next-generation radar software platform advancing mission-critical security for defense and automotive applications. You’ll play a key role in architecting robust solutions, collaborating across engineering, product, and UX, and ensuring our technology thrives in real-world, dynamic environments.

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.

REQUIRED SKILLS / EXPERIENCE

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.

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
