Front End Developer Startup Jobs in Washington, DC

Rune Technologies builds mission-critical software for military logistics and sustainment. Our flagship product is TyrOS, an AI-enabled logistics command and control platform that gives commanders a single, real-time operating picture of their sustainment fight, from inventory and distribution to medical and operational planning, even in degraded and contested environments.

We’re not a traditional defense contractor. We’re a small, fast-moving team that combines deep operational experience in and with the DoD with the software discipline of the best product companies, and we apply that combination to a customer set that desperately needs it. We stay close to our users by embedding directly with military units during exercises and rotations, and we ship constantly based on what we learn.

The U.S. military and its allies face a real logistics modernization problem. We’re building the software to solve it.

At Rune Technologies, we are building the logistics technology backbone that the U.S. and allied militaries need to dominate in large-scale combat operations. As a Front End Software Engineer at Rune, you will be part of a high-impact team working at the intersection of modern web engineering, operational logistics software, and mission-critical user experiences -- all in support of the warfighter at the tactical edge.

You’ll join us in our mission to bring 21st-century software to the sustainment domain -- modernizing inventory management, transportation optimization, and predictive maintenance through intuitive, high-performance applications. You’ll work closely with product designers, backend engineers, and operational experts to build software that transforms complex logistics workflows into powerful and accessible user experiences.

This is a front-end engineering role first and foremost. We’re looking for someone who has dedicated their career to building sophisticated web applications, possesses deep expertise in React or Angular, TypeScript, and modern JavaScript, and takes pride in owning front-end architecture and technical direction. The ideal candidate is a builder who has created significant products from the ground up, thrives in fast-moving environments, and cares deeply about delivering software that performs reliably in real-world operational settings.

• Design, build, and maintain complex, production-grade front-end applications using React (preferred) or Angular, TypeScript, and modern JavaScript.
• Own front-end architecture decisions, establishing scalable patterns, frameworks, and engineering best practices that support long-term product growth.
• Develop intuitive user experiences that enable operators to rapidly understand and act on complex logistics and operational data.
• Collaborate closely with product designers, backend engineers, and military subject matter experts to translate mission requirements into high-quality software.
• Build data-intensive interfaces, visualizations, and real-time user experiences that surface critical operational insights.
• Integrate with APIs, WebSocket-based services, and distributed backend systems to deliver responsive, high-performance applications.
• Contribute to code reviews, technical design discussions, and engineering standards that raise the quality and maintainability of the platform.
• Diagnose and resolve performance bottlenecks, usability issues, and production incidents to ensure reliability in demanding operational environments.
• Help shape the future of Rune’s front-end platform by identifying opportunities for technical innovation, improved developer experience, and enhanced user impact.

• Expert in React (preferred) or Angular — one must be primary, not both at a surface level
• TypeScript and JavaScript as primary languages; strong command of HTML
• 4+ years of experience with 75%+ in pure front end roles
• Has built significant, non-trivial front-end products — not just maintained existing codebases
• Can own front end architecture decisions, not just implement tickets

• Portfolio demonstrating independent, significant front-end work (common for strong FEEs)
• Experience with data-intensive front ends and data visualization (D3.js or similar)
• Experience with mapping libraries — Mapbox, MapLibre
• WebSockets experience — real-time, high-throughput UI
• Has worked at a startup and built something from scratch
