Title: Senior Software Engineer Location: Herndon, Virginia, 20171, United States Department: Soft Engineer Job category: Soft Engineer Requisition number: SENIO001896 - Full-time - Hybrid - Locations Showing 1 location US Corp Office Herndon, VA 20171, USA Job Description: Job details Description Overview- We're looking for a senior builder — a high-output engineer who ships production systems at a pace that resets expectations and raises the bar for everyone around them. Not an architect who whiteboard-only. Not a reviewer who lives in PRs. A hands-on engineer whose default mode is writing, deploying, and owning code — and whose experience means fewer wrong turns and faster recovery when things get hard. You'll take on the work that demands senior judgment: platform migrations with no clean path, production-ready prototypes that become the foundation others build on, architectural rebuilds that have to stay live through the transition, and cross-system integrations that touch everything and are owned by no one. You scope it, you build it, you ship it — and you leave it better documented and more maintainable than you found it. We operate in a FedRAMP Moderate / CMMC L2 environment serving major defense primes. Compliance is a constraint you've internalized — not a blocker you escalate. Responsibilities: Your day if you join us: What You'll Build: Build (70%+) - Write production code daily across Angular/TypeScript, .NET/C#, Python, or whatever the problem requires. - Use AI coding tools—Claude Code, Copilot, agentic workflows—as your native development environment and actively raise the bar for how the team uses them. - Own systems end-to-end: architecture → implementation → testing → deployment → You deeply understand the constraints of FedRAMP and CMMC and you design around them without slowing down. - Build on Azure Gov and Commercial using microservices, event-driven patterns, APIs, and data pipelines — and make deliberate architectural decisions that others can build on. - Drive delivery of complex, high-impact projects: migrations, prototypes, legacy replacements, and cross-system integrations that require senior judgment to scope and execute. - Lead IaC (Terraform, Bicep), CI/CD automation, and internal tooling that accelerates the whole engineering organization. Raise the Bar (20%) - Your code and architecture decisions become the reference standard for engineering quality across the team. - Lead code reviews with depth and speed; mentor through pairing, not lectures. - Champion AI-augmented development across the team — prompting strategies, workflow patterns, context management, and tool selection. - Author practical, durable documentation (READMEs, ADRs, runbooks) that outlasts any single sprint. - Identify and close skill gaps on the team through example, not just feedback. - Provide authoritative signal on platform gaps, tooling choices, and systemic engineering friction — and propose solutions, not just observations. - Evaluate new technology by building with it in real environments with real data, then synthesize findings for the broader team. - Own the identification and prioritization of technical debt that materially slows delivery or increases risk. - Partner with product and engineering leadership to influence roadmap tradeoffs from a grounded technical perspective Qualifications: You are a great fit for this role if you: Must‑Haves You are a Builder - 8–10 years of recent, hands-on software engineering with a track record of shipping full systems, not just features. - Deep proficiency in at least two: Angular/TypeScript, .NET/C#, Python, Java — with the ability to move across stacks as needed. - Extensive experience designing and building cloud-native systems (Azure preferred; Azure Gov a plus). - Comfortable owning the full stack — infra → backend → frontend — and making the right tradeoffs at each layer. AI-Native Workflow - Daily user of Claude Code, Copilot, Cursor, Windsurf, or equivalent — this is how you work, not a novelty. - Strong, earned mental model of where AI accelerates development and where human judgment is irreplaceable. - Demonstrated examples of shipping faster and better with AI assistance and sharing those techniques with others. Judgment & Engineering Maturity - Thrives in ambiguity; makes reasonable assumptions, communicates them clearly, and ships. - Strong but flexible architectural opinions — you can defend your reasoning and update it when presented with better information. - Clear, precise written communication; you write to inform decisions, not to document effort. Preferred Qualifications: You are exactly who we are looking for if you: - Have hands-on experience with Azure Government (IL2/IL4/IL5), Entra ID, PIM, managed identities, and Zero Trust architecture. - Proven experience building in regulated environments (FedRAMP, CMMC, ITAR, SOC2, HIPAA). - Bring a background in IAM, credentialing, PKI, or federated identity. - Have built dev tools, internal platforms, or shared infrastructure used by other engineering teams. - Have worked in Aerospace & Defense, Life Sciences, or other regulated SaaS environments. - Have meaningful agentic AI development experience (MCP, multi-tool workflows, AI-driven testing) and can speak to what worked and what didn't. - Have a prototype or side project that demonstrates what senior-level AI-augmented development looks like in practice.
