The posting refers to the role as both Senior Software Engineer, Fullstack and Principal Software Engineer.

Requirements

• 7+ years building customer-facing, production-grade software systems.
• Modern full-stack expertise with React or equivalent front-end technologies and asynchronous backend services such as Tokio/Rust or similar.
• Strong experience with modular architectures, documented API contracts, and robust service lifecycles.
• Experience designing for real-world constraints, such as field, defense, or automotive deployments, or similar high-stakes, performance-critical systems.
• Hands-on experience with Python and/or Rust and/or C/C++ for practical, scalable solutions.
• Ability to collaborate with product, UX, and technical experts, with strong cross-functional communication.
• Track record of mentoring peers and driving technical excellence without direct authority.

• B.S. in Computer Science or equivalent industry experience.
• Must identify during the application process whether they are a U.S. citizen or green card holder, or have asylum/refugee status in the U.S., so Echodyne can evaluate eligibility to handle export-controlled information or obtain required government authorizations.

Responsibilities

• Deliver core platform components, including asynchronous Tokio/Rust backend services, well-defined APIs, and real-time data and event models.
• Partner with React/front-end teams to support shared components, efficient state management, and system health visualizations.
• Advance prototypes to production by turning algorithms or domain logic into well-tested, high-performance endpoints with observability.
• Architect for resilience, including intermittent connectivity, graceful degradation, security hardening, and offline scenarios.
• Improve CI/CD and testing, including performance, contract, and property testing, and establish instrumentation and SLO/error budgets.
• Mentor and influence through clear design narratives and code reviews, and incorporate product and field feedback into the development lifecycle.

Benefits

• Restricted Stock Units (RSUs).
• Fully paid medical, dental, and vision insurance premiums for the employee.
• Choice of PPO or HDHP/HSA.
• Virtual care through 98Point6.
