We build autonomy systems for air, maritime, space, and other platforms operating in complex and contested environments.\nForge 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.\nJob Description:\nWe 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.\nShield AI’s Hivemind developers are the platform’s primary design partners and proving ground. Forge is also designed for external engineering teams to adopt, extend, and integrate into their own environments.\nYou will help evolve Forge into an integrated engineering environment with shared foundations for APIs, user interfaces, extensions, model integrations, and agent tools. Working across frontend architecture, backend services, and model integrations, you will validate the platform through real workflows. Your work will help engineers understand complex systems, develop autonomy software, investigate failures, and deliver reliable capabilities faster.\nWhat you'll do:\nBuild and operate a front-end focused development platform embedded in the workflows used to train, validate, and deploy the AI Pilot.\n\nDesign a composable UI architecture that lets applications contribute apps, dashboards, commands, widgets, and shared resource context.\n\nDefine typed, versioned contracts between the platform and independently developed Forge applications.\n\nCreate workflows for teams to package, publish, configure, install, upgrade, and disable applications.\n\nEnable Forge’s native AI experiences and external agent harnesses to understand active context, invoke authorized tools, navigate applications, and compose dashboards.\n\nDeliver consistent application behavior across local-development and AI Factory environments.\n\nPartner with simulation, autonomy, and ML subject-matter experts to build initial applications, validate the platform against real workflows, and incorporate what you learn.\n\nWork across infrastructure, security, product, and design to shape the platform’s architecture and engineering practices.\n\nKey outcomes:\nA successful engineer in this role will help deliver the following outcomes:\nBuild and operate a front-end focused development platform embedded in the workflows used to train, validate, and deploy the AI Pilot.\n\nDesign a composable UI architecture that lets applications contribute apps, dashboards, commands, widgets, and shared resource context.\n\nDefine typed, versioned contracts between the platform and independently developed Forge applications.\n\nCreate workflows for teams to package, publish, configure, install, upgrade, and disable applications.\n\nEnable Forge’s native AI experiences and external agent harnesses to understand active context, invoke authorized tools, navigate applications, and compose dashboards.\n\nDeliver consistent application behavior across local-development and AI Factory environments.\n\nPartner with simulation, autonomy, and ML subject-matter experts to build initial applications, validate the platform against real workflows, and incorporate what you learn.\n\nWork across infrastructure, security, product, and design to shape the platform’s architecture and engineering practices.\n\nRequired qualifications:\nExperience owning production full-stack applications from design and implementation through rollout and support.\n\nStrong proficiency with TypeScript and React or an equivalent modern web stack.\n\nExperience building production backend services in Go, Python, Rust, or a comparable language.\n\nExperience designing typed, versioned APIs and contracts between independently deployed components.\n\nStrong knowledge of web and distributed-system architecture, including state management, routing, asynchronous communication, browser security, authentication, authorization, and failure handling.\n\nExperience building real-time and high-performance applications (WebGL, WebGPU)\n\nSound judgment about when to extend an existing system, introduce an abstraction, or keep a solution intentionally small.\n\nClear communication skills and the ability to work across frontend, backend, infrastructure, and product disciplines.\n\nPreferred qualifications:\nExperience in every area below is not expected. Relevant experience may include:\nExtensible application platforms, including plugin systems, micro-frontends, web sandboxing, Web Components, or VS Code extensions.\n\nAgent-tool integrations and protocols such as Model Context Protocol.\n\nAPI gateways, reverse proxies, service catalogs, or policy-driven routing.\n\nSchema-driven API development using OpenAPI, JSON Schema, Protocol Buffers, gRPC, or generated clients.\n\nKubernetes and ingress/gateways\n\nComposable user experiences such as dashboard builders, configurable layouts, data visualization, or collaborative application state.\n\nRobotics, autonomy, simulation, aerospace, or other domains where software interacts with real-world systems.\n\nShipping Electron Applicatitions\n\nWhy join us:\nConnect your work directly to the mission. The platform and applications you build help engineers develop, validate, and deliver the autonomy software behind Hivemind. \nDefine human-and-agent workflows. Design how engineers and AI agents use the same platform tools while preserving user control, security, and accountability. \nOwn complete workflows. Work across user experience, frontend architecture, backend services, APIs, deployment, and operations. \nBuild alongside engaged users. Partner with engineers solving autonomy, simulation, data, and infrastructure problems, and see the direct effect of your decisions.","description_format":"text","description_chars":6030,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Military Drones","Defense Manufacturing","Defense AI","Drone AI"],"lifecycle":[{"event":"open","at":"2026-10-28T23:22:02Z"}],"visa":[{"country":"US","licensed_sponsor":true,"evidence":"H-1B filings in 12 months: 2","filings_12m":2,"filings_prev_12m":2,"green_card_filings_12m":0,"median_offered_wage_usd":132500,"route":null,"cap_exempt":false,"checked_at":"2026-10-29T16:27:21+00:00","sources":["US Department of Labor: LCA disclosure data (H-1B, H-1B1, E-3)","US Department of Labor: PERM disclosure data (green cards)"],"filings_for_role_12m":1}],"liveness":{"score":63,"band":"ok","label":"Likely open","p_open":1,"p_active":0.632,"p_room":1,"age_days":1,"expected_fill_days":65,"reasons":["conf:0","stale_co","velocity","win:early","comp:brand"],"computed_at":"2026-10-30T05:48:23Z"},"pay":{"stated_usd_annual":240000,"is_top_pay":true},"html_url":"https://alion.io/job/shield-ai-senior-software-engineer-frontend-platform-r5790","json_url":"https://alion.io/job/shield-ai-senior-software-engineer-frontend-platform-r5790.json","meta":{"generated_at":"2026-10-30T21:24:30Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":11858,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-31T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":50},"rest":"https://alion.io/mcp/rest/get_company?id=50"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fshield-ai-senior-software-engineer-frontend-platform-r5790"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fshield-ai-senior-software-engineer-frontend-platform-r5790"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fshield-ai-senior-software-engineer-frontend-platform-r5790"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/shield-ai-senior-software-engineer-frontend-platform-r5790\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fshield-ai-senior-software-engineer-frontend-platform-r5790"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3428593}},{"tool":"search_jobs","arguments":{"company":"shield.ai","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3428593},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
