About Shield AI

Shield AI is a defense technology company with the mission of protecting service members and civilians with intelligent systems. We build autonomy systems for air, maritime, space, and other platforms operating in complex and contested environments.
Forge is the engineering platform used to build, integrate, test, and operate Hivemind capabilities. It connects autonomy developers with the applications, services, compute, data, and workflows they need to move from local development to deployed systems.
The Role

We are looking for a full-stack engineer with strong frontend expertise who enjoys building customer-facing products, developer tools, and AI-assisted workflows. Your primary focus will be designing and building intuitive, responsive applications in TypeScript and React, with backend development and service integration as needed to deliver complete workflows.
You will partner with internal subject-matter experts to build Forge applications for simulation, synthetic data generation, test and evaluation, and autonomy performance. You will use shared platform components and design application extension points that let downstream teams specialize these workflows.




Shield AI's internal Hivemind Pilot developers and Hivemind Solutions groups are your primary design partners. You will work directly with them to understand requirements, evaluate solutions, and improve the user experience through real use.
Your work will help engineers understand complex systems, accelerate the development of autonomy software, and deliver reliable systems faster.
What you'll do:

Design and build frontend experiences in TypeScript and React for autonomy development workflows such as simulation, synthetic data generation, and test and evaluation.
Translate complex technical workflows into intuitive apps and workflows.
Partner with Hivemind Pilot developers, Hivemind Solutions teams, product, and design to understand user needs and improve applications through feedback.
Use Forge's UI Platform to deliver consistent application experiences and drive improvements through collaborating on concrete requirements.
Integrate domain APIs and services, building or extending backend capabilities as needed to complete application workflows.
Design reusable application components and extension points that let other teams specialize workflows.
Key outcomes:

A successful engineer in this role will help deliver the following outcomes:
Hivemind teams adopt Forge applications that make it easier to develop, integrate, test, and diagnose autonomy capabilities.




Engineers can complete workflows across domain services through coherent application experiences, with clear progress, results, and paths to investigate failures.
Applications behave reliably across supported local, cluster, edge, and air-gapped environments.
Other teams can extend and specialize application workflows through documented APIs and extension points.
Engineers and AI agents can use application capabilities with appropriate permissions, visibility, and user control.
Required qualifications:

Experience delivering and supporting production web applications, with substantial ownership of frontend architecture and user experience.
Strong proficiency with TypeScript and React, including component design, state management, asynchronous data handling, routing, auth, and web architecture.
Ability to translate complex technical workflows into intuitive interfaces in collaboration with users, subject-matter experts, and designers.
Experience building responsive, accessible interfaces and diagnosing frontend performance issues with profiling.
Experience integrating APIs and handling loading states, errors, long-running operations, and evolving service contracts.
Ability to work across the stack, including reading, debugging, and extending backend services in Go, Python, or a comparable language.
Experience testing UI components, application behavior, and complete user workflows.
Sound judgment about when to use shared platform capabilities, contribute reusable improvements, or keep a solution specific to an application.
Clear communication skills and the ability to collaborate across product, design, platform, and domain teams.
Preferred qualifications:

Experience in every area below is not
