You will be a senior technical contributor on a small, cross-functional product team responsible for evolving the platform and establishing the engineering practices, architecture, and technical foundation needed for its long-term success.\nThis is not a role focused on maintaining a backlog or implementing narrowly defined tickets. You will own complex capabilities from concept through production, make consequential technical decisions, identify and resolve architectural risks, and help guide less-experienced engineers. The successful candidate will be comfortable operating with significant autonomy in an environment where the roadmap and technical approach are still being formed.\nThis position requires an active TS/SCI security clearance.\nAbout the Team\nIronSled sits within LMI’s Chief Technology Office. We are a small, high-visibility team building a secure application-hosting platform for federal agencies. Our culture operates more like a product-focused startup than a traditional government contracting program. We move quickly, use focused design spikes to resolve uncertainty, and prioritize working outcomes over unnecessary process.\nAt the same time, we are building for users who require reliability, security, auditability, and trust. Strong engineering judgment, disciplined execution, and attention to detail are essential.\nYou will work closely with the Product Manager, Engineering Lead, platform engineers, and product stakeholders. Because the IronSled roadmap and architecture are continuing to evolve, you will have meaningful influence over the platform’s technical direction, engineering standards, and user experience.\nLMI is a new breed of digital solutions provider dedicated to accelerating government impact through innovation and speed. By investing in technology and prototypes ahead of need, LMI delivers commercial-grade platforms and mission-ready artificial intelligence capabilities to federal agencies at commercial speed.\nHeadquartered in Tysons, Virginia, LMI supports the defense, space, healthcare, and energy sectors, helping agencies navigate complexity, modernize critical capabilities, and strengthen mission outcomes.\nResponsibilities\nWhat You’ll Do\nOwn complex full stack features from architecture and data design through deployment and production support.\nBuild across Angular, TypeScript/Express, PostgreSQL, and external platform integrations.\nMake technical decisions involving APIs, identity, permissions, security, reliability, and data architecture.\nPartner directly with product leadership to turn ambiguous needs into practical solutions.\nEstablish engineering standards, review designs and code, and mentor other engineers.\nIdentify technical risks, improve platform architecture, and balance delivery speed with long-term maintainability.\nQualifications\nWhat We’re Looking For\n7+ years of professional software engineering experience, including ownership of production full stack applications.\nStrong experience with TypeScript, Angular, Node.js or Python, PostgreSQL, and RESTful API design.\nDemonstrated ability to independently lead complex features and make sound architectural decisions.\nExperience with authentication, authorization, secure application design, testing, and production troubleshooting.\nAbility to operate effectively with incomplete requirements and limited day-to-day direction.\nExperience mentoring engineers and improving team development practices.\nActive use of AI-assisted development tools in a disciplined engineering workflow.\nU.S. citizenship and the ability to obtain a security clearance.\nWhat Will Set You Apart\nExperience working on a PaaS, internal developer platform, developer portal, or cloud-native product.\nExperience with Kubernetes, GitOps, CI/CD pipelines, containers, and event-driven integrations.\nExperience integrating with GitLab, Okta, Entra ID, OIDC, SAML, Trivy, Fleet, or similar technologies.\nExperience developing software under federal security and compliance requirements.\nExperience across cloud and on-premises environments.\nA strong portfolio, open-source contributions, or other evidence of building products outside assigned work.\nTarget salary range: $111,000 - $211,000\nThe salary range displayed represents the typical salary range for this position and is not a guarantee of compensation. Individual salaries are determined by various factors including, but not limited to location, internal equity, business considerations, client contract requirements, and candidate qualifications, such as education, experience, skills, and security clearances.\nApplicants must meet eligibility requirements for a U.S. Government security clearance. Only US Citizens are eligible for a security clearance. For this position, LMI will only consider applicants with security clearances or applicants who are eligible for security clearances, due to the nature of the work.\nJob Locations\nUS-Remote","description_format":"text","description_chars":5104,"description_truncated":false,"requirements":{"experience_years_min":7,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":true,"languages":[]},"benefits":["Equity"],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Digital Government","IT Consulting & Digital Transformation","Management Consulting"],"lifecycle":[{"event":"open","at":"2026-11-12T20:16:50Z"}],"visa":[],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":0,"expected_fill_days":17,"reasons":["conf:0","win:early","comp:brand"],"computed_at":"2026-11-12T21:14:12Z"},"pay":{"stated_usd_annual":211000,"is_top_pay":true},"html_url":"https://alion.io/job/lmi-senior-full-stack-developer-3","json_url":"https://alion.io/job/lmi-senior-full-stack-developer-3.json","meta":{"generated_at":"2026-11-12T21:14:12Z","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":44896,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-13T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.1,"usd":0.01,"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":721749},"rest":"https://alion.io/mcp/rest/get_company?id=721749"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Flmi-senior-full-stack-developer-3"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"free","price":{"credits":0,"usd":0},"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%2Flmi-senior-full-stack-developer-3"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.1,"usd":0.01},"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%2Flmi-senior-full-stack-developer-3"},{"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/lmi-senior-full-stack-developer-3\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Flmi-senior-full-stack-developer-3"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":4194655}},{"tool":"search_jobs","arguments":{"company":"lmisolutions.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":4194655},"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.
