OnFrontiers is the expert network built to change that. We connect the organizations that win and deliver government work with a vetted network of 17,000+ practitioners who have actually done it. We're also building that expertise into the AI workflows teams already use, so the right person informs the right task at the moment it counts.\nWe create value for the whole GovCon ecosystem:\nFor contractors, we lower the friction of engaging the right subject-matter expert at the right time, turning a labyrinth into a fair, merit-based advantage that rewards what a team knows, not who it knows.\nFor experts leaving government, we open a direct path to put hard-won expertise to work, engage with mission-driven companies, and often build a second career.\nFor government, we grow an expert ecosystem around public work that gets better solutions into agencies faster and helps keep institutional knowledge from walking out the door.\nWe're a lean, AI-native team building the infrastructure for how expertise gets deployed. This is a chance to build not just a product, but an industry-defining technology.\nThe Role\nAs a full-stack engineer on our team, you'll build and ship the next generation of our expert intelligence platform. You'll code every day across the stack, from LLM-powered features to the APIs and interfaces that deliver them, working closely with our engineering lead and the rest of the team to get new capabilities into customers' hands quickly.\nThis is a hands-on building role on a small, AI-native team. Your work ships fast and matters immediately, and you'll have real ownership of the features you take from idea to production.\nWhat You'll Do\nBuild LLM-powered systems for expert matching and solicitation intelligence.\nBuild and improve our vector-backed indexes of experts and solicitations, and the search that connects them (OpenSearch, PGVector, Go).\nShip features that accelerate talent mobility by graphing knowledge at the individual work-experience level.\nBuild core SaaS platform and API features across the stack (Python, Go, React).\nTake features from idea to production: write clean, tested, maintainable code and own what you ship.\nWork AI-first: pair with Claude and our internal tooling to design, write, test, and review code, and help improve how we build.\nCollaborate directly with the engineering lead, product, and leadership to ship quickly and iteratively.\nBalance startup speed with the things that keep a platform healthy: security, reliability, and scalability.\nWhat We're Looking For\nProven experience shipping full-stack software in Python, React, and AWS. Go is a plus.\nHands-on experience with LLMs, LLM orchestration, vector search, or AI-first product development.\nYou already build with AI tools daily (Claude, Copilot, or similar) and want to go deeper.\nStartup speed: comfortable with ambiguity, fast iteration, and wearing many hats.\nSolid engineering fundamentals: you write readable, tested code and care about what happens in production.\nMission-driven, hungry, and eager to own outcomes.\nComfortable engaging on data security and compliance topics (CMMC / FedRAMP / SOC 2 familiarity a plus, not required).\nWhy Join\nImpact: your work will directly shape how $100B+ in government contracting decisions get made.\nEquity upside: a meaningful ownership stake.\nGrowth path: join early and grow with the team, with room to take on more scope and seniority as we expand.\nMission: build AI-first technology that modernizes how government and industry collaborate.","description_format":"text","description_chars":3643,"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":["Equity"],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-10-14T12:07:16Z"}],"visa":[],"liveness":{"score":8,"band":"cold","label":"Long shot","p_open":1,"p_active":0.271,"p_room":0.28,"age_days":105,"expected_fill_days":27,"reasons":["conf:0","win:tail","crowd:"],"computed_at":"2026-10-15T02:37:55Z"},"pay":null,"html_url":"https://alion.io/job/onfrontiers-software-engineer-full-stack-ai-first","json_url":"https://alion.io/job/onfrontiers-software-engineer-full-stack-ai-first.json","meta":{"generated_at":"2026-10-15T02:37:55Z","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":3871,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-16T00:00:00Z"}},"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":4397126},"rest":"https://alion.io/mcp/rest/get_company?id=4397126"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fonfrontiers-software-engineer-full-stack-ai-first"},{"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%2Fonfrontiers-software-engineer-full-stack-ai-first"},{"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%2Fonfrontiers-software-engineer-full-stack-ai-first"},{"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/onfrontiers-software-engineer-full-stack-ai-first\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fonfrontiers-software-engineer-full-stack-ai-first"}]}
