## About the Role

* 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

## Description

* 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.
