Principal Software Engineer (Fullstack)

Echodyne Corp•Kirkland, WA

About The Position

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.

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.
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.
