Senior Engineer, Full-Stack - Forge Platform, Tools (R5790)

Shield AI is a venture-backed defense-tech company with the mission of protecting service members and civilians with intelligent systems.

We are looking for a full-stack engineer interested in customer-facing products, developer tools, and AI-assisted workflows. You will partner with internal subject-matter experts to build an extensible application platform and complete applications on it.

Responsibilities

• Build and operate a full-stack platform embedded in the workflows used to train, validate, and deploy the AI Pilot.
• Design a composable UI architecture that lets applications contribute widgets, dashboards, commands, and shared resource context.
• Define typed, versioned contracts between the platform and independently developed Forge applications.
• Create workflows for teams to package, publish, configure, install, upgrade, and disable applications.
• Enable Forge’s native AI experiences and external agent harnesses to understand active context, invoke authorized tools, navigate applications, and compose dashboards.
• Deliver consistent application behavior across local-development and remote-cluster environments.
• Partner with simulation, autonomy, and ML subject-matter experts to build initial applications, validate the platform against real workflows, and incorporate what you learn.
• Work across infrastructure, security, product, and design to shape the platform’s architecture and engineering practices.

Key Outcomes

• Applications behave consistently across local-development and remote-cluster environments, even when their deployment and service lifecycles differ.
• Application developers can move quickly using clear contracts, examples, documentation, and authoring guides.
• Hivemind teams can develop, integrate, test, and diagnose autonomy capabilities more quickly using Forge applications and platform services.
• Users can combine applications, tools, and shared context into persistent workflows tailored to their needs and share those workflows within their organization.
• Internal teams and external customers can build integrated Forge applications that extend these workflows without modifying the core platform.
• Forge’s embedded AI and external agent harnesses can explore and operate the same catalog of platform tools through shared contracts.

Requirements

• Experience owning production full-stack applications from design and implementation through rollout and support.
• Strong proficiency with TypeScript and React or an equivalent modern web stack.
• Experience building production backend services in Go, Python, Rust, or a comparable language.
• Experience designing typed, versioned APIs and contracts between independently deployed components.
• Strong knowledge of web and distributed-system architecture, including state management, routing, asynchronous communication, browser security, authentication, authorization, and failure handling.
• Ability to build intuitive technical tools for engineers and test them at the unit, integration, and system levels.
• Sound judgment about when to extend an existing system, introduce an abstraction, or keep a solution intentionally small.
• Clear communication skills and the ability to work across frontend, backend, infrastructure, and product disciplines.
