Front End Software Engineer

Location: Onsite | Rosslyn, VA; New York City, NY; Seattle, WA

Work Authorization: U.S. Citizen

Clearance: Must be eligible to obtain a Secret or Top Secret/SCI security clearance

Employment Type: Full-time, salaried, with full benefits

The Company & Mission:

Our client builds mission-critical software for military logistics and sustainment. Their flagship product is an advanced 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.

They'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, applying that combination to a customer set that desperately needs it. They stay close to their users by embedding directly with military units during exercises and rotations, and they ship constantly based on what they learn.

The U.S. military and its allies face a real logistics modernization problem. Our client is building the software to solve it.

What This Role is All About:

Our client is 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, you'll 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 help 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. They'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.

What You’ll Be Doing:

• 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 their front-end platform by identifying opportunities for technical innovation, improved developer experience, and enhanced user impact

What You Bring:

• Expert in React (preferred) or Angular; one must be primary, not both at a surface level


• TypeScript and JavaScript as primary languages, with a 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

Bonus Points:

• Portfolio demonstrating independent, significant front-end work


• Experience with data-intensive front ends and data visualization (D3.js or similar)


• Experience with mapping libraries such as Mapbox or MapLibre


• WebSockets experience with real-time, high-throughput UI


• Has worked at a startup and built something from scratch

Benefits:

• Comprehensive medical, dental, and vision plans; premiums 100% covered for all employees; exceptionally low premiums for spouses and dependents


• Basic life insurance and disability 100% covered for all employees; option to purchase additional life insurance


• "Take the time off that you need, when you need it" paid time off policy, not accrual based


• Generous company holiday calendar including a December shutdown


• Supportive leave of absence program including military service, medical events, and parental leave


• Full 401(k) retirement plan for all full-time eligible employees


• Company-funded commuter benefits


• Free access to on-site gym at the office


• Highly competitive equity grants included in the majority of full-time offers as part of total compensation
