Principal Software Engineer (Fullstack)

Echodyne is seeking a Principal Software Engineer to join our fast-growing team.

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

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.
