Senior Software Engineer (.NET/Angular)

About the role

Own the hard parts of a federated enterprise platform for complex federal mission environments. You will help build the architecture, engineering culture, and technical foundation of SyncCore™ and SyncPoint™, taking ownership of significant capabilities from architecture and domain modeling through APIs, event‑driven workflows, data persistence, user experience, testing, deployment, and production performance.

Responsibilities

• Own significant capabilities across SyncCore or SyncPoint—from architecture and domain modeling through APIs, event‑driven workflows, data persistence, user experience, testing, deployment, and production performance.
• Decide how services communicate, where boundaries belong, how data moves through the system, and how to build software that stays secure, observable, maintainable, and extensible as the platform grows.
• Help raise the engineering capability of the team through thoughtful code reviews, mentoring junior and mid‑level engineers, challenging architectural assumptions, and establishing useful patterns.
• Work on the SyncCore platform (identity, integration, eventing, canonical data, shared services, governance, auditability, platform APIs) or lead the engineering of a SyncPoint mission module that turns complicated operational processes into intuitive software.
• Stay close to the problem, the architecture, and the decision‑makers with no layers of bureaucracy separating you from impact.

Requirements

• Typically 7+ years of professional software development experience.
• Advanced C# and modern .NET / ASP.NET Core.
• Strong enterprise backend and REST API development at scale.
• Deep relational data and ORM experience, including design and performance work.
• Angular or comparable modern enterprise frontend experience.
• Experience with asynchronous messaging and event‑driven systems — sagas, eventual consistency, idempotency, and the failure modes that only appear in production.
• Experience with distributed or microservice‑based applications.
• Strong automated testing and diagnostic instincts.
• Ability to independently own complex features or entire application components.
• Real experience conducting technical code reviews and mentoring other engineers.
• Strong alignment with the current .NET / Entity Framework / PostgreSQL / Angular / RabbitMQ stack.

Qualifications

• U.S. citizenship is required (no exceptions).
• An active Secret clearance is welcome; otherwise interim Secret eligibility is required, with sponsorship available.
• Hybrid work schedule: a few days per week at the Arlington HQ (2550 S. Clark Street).
