Our vision is to reimagine American manufacturing as a hyperconnected, secure, and resilient ecosystem of local and regional suppliers who can more easily connect, interact, and do business with the industry and government customers that rely on them. We are a dual-use technology platform that supports both DoD and commercial customers in pursuit of our vision.\nROLE OVERVIEW\nWe need a Staff Software Engineer to set technical direction and ship fast. You are a hands-on individual contributor with Tech Lead responsibility. You own the hard architectural calls, write production code, and make the engineers around you faster and better. We are scaling. Your job is to help us grow without breaking what works.\nRESPONSIBILITIES\nLead technical design for major features and own the architecture of our ABP-based applications: module boundaries, shared libraries, and the conventions other teams build on.\nShip production full-stack code at a high standard, including the hardest and most ambiguous problems.\nOwn the quality end-to-end\nRaise engineering standards through code review, design review, and direct mentoring.\nSet the team's .NET standards and enforce them in code review and CI.\nBuild secure-by-design systems, including for AWS GovCloud and government customer environments.\nOwn reliability, performance, and observability of what you ship. Own failures and fix root causes.\nEvaluate tools, frameworks, and methods, and make the call.\nPlan and lead .NET and ABP major-version upgrades across our services while feature work continues.\nTranslate customer and business needs into clear technical priorities with the Director of Engineering and Product.\nDocument decisions so the team can execute without you in the room.\nQUALIFICATIONS\n8+ years of professional software engineering, including multiple years owning architecture of production systems.\nProven record of leading technical delivery across a team without formal authority.\n5+ years building production systems in C# and ASP.NET Core. You know the request pipeline, dependency injection lifetimes, and async behavior well enough to debug them under load.\nStrong EF Core and PostgreSQL experience: migration strategy across environments, query plans, indexing, and concurrency control.\nProduction experience with ABP Framework is strongly preferred. Deep experience with the same patterns in another .NET framework is a reasonable substitute if you can learn ABP quickly.\nYou have found and fixed .NET performance problems in production with tools like dotnet-trace, dotnet-counters, or Datadog APM.\nWorking proficiency in Angular and TypeScript, enough to ship features end to end.\nExperience with distributed systems, cloud infrastructure (AWS), containers, and CI/CD.\nSecure coding discipline and experience in regulated or high-assurance environments.\nClear written and verbal communication. You can brief engineers and executives.\nAbility to obtain and maintain a US government security clearance. Certain programs may require US citizenship.\nEarly-stage startup or SaaS experience is a plus.\nOUR STACK\nC#, ASP.NET Core, ABP Framework, EF Core, Angular, PostgreSQL, Kafka (Amazon MSK), Docker, Kubernetes, Terraform, AWS (including GovCloud), GitLab, Datadog\nSustainment offers a competitive benefits package for full time employees including medical, dental, vision, paid time off, company holidays, and 401K matching.\nSustainment is proud to be an equal opportunity employer.
