Mid-Level Software Engineer (.NET/Angular)

Overview

Responsibilities

• As a Mid-Level Software Engineer, you will own meaningful pieces of the platform or a SyncPoint module from design through production.
• You might build an API one sprint, design an event-driven workflow the next, work through a difficult data-modeling problem with an architect, or take a feature from an Angular interface all the way through the application and data layers.
• You will work alongside senior engineers and architects, but we expect you to bring ideas to the table, challenge assumptions, make engineering decisions, and increasingly own the technical outcome—not simply implement someone else's design.
• On the platform side, you may work on capabilities such as identity, integration, eventing, shared services, data architecture, auditability, and platform APIs.
• On a module team, you will translate complex real-world mission and business problems into software people actually depend on to do their jobs.

What We Actually Require

• Typically 3+ years of professional software development experience.
• Strong professional experience with C# and modern .NET / ASP.NET Core.
• The ability to independently build REST APIs, backend services, and real business logic — not just wire up someone else's design.
• Entity Framework Core or a comparable ORM, and the judgment to know when to drop to SQL instead.
• Strong relational database fundamentals. You can read a query plan without flinching.
• Experience writing automated unit and integration tests, as a habit rather than a chore.
• Working experience with JavaScript or TypeScript and modern web applications.
• The ability to deliver a complete, production-ready feature end to end.
• Backend .NET depth matters more to us than an exact full-stack match.
• Strongly preferred, not required: PostgreSQL, Angular, RabbitMQ, Docker, Azure, distributed systems, microservices, event-driven patterns.

The Stack

• C#, .NET 8+, ASP.NET Core, a CQRS-lite command pipeline, PostgreSQL with Entity Framework Core, RabbitMQ for asynchronous and event-driven flows, Angular 19 and TypeScript, Docker, CI/CD, Azure Government, xUnit, and micro-frontends.

Clearance, Citizenship, and Location

• U.S. citizenship is required. No exceptions. Federal program requirement, not negotiable.
• An active clearance is not required to apply. Active Secret is welcome. Otherwise you need to be eligible for an interim Secret, and PE sponsors — we handle the paperwork and walk you through the process.
• Hybrid, a few days a week at our Arlington HQ, 2550 S. Clark Street.

Compensation

• $112,000 – $132,000 based on demonstrated depth, scope of prior responsibility, and interview performance.

Benefits

• Paid time off, 10 paid holidays, medical, dental, and vision, company-paid life and AD&D, company-paid short- and long-term disability, 401(k) with company contribution, legal assistance, tuition reimbursement, and continuing education opportunities.
