Junior Software Engineer (.NET/Angular)

Full Time Arlington, VA, US

Salary Range: $96,000.00 To $112,000.00 Annually

About Pioneering Evolution: The Navy moves billions of dollars a year through budgeting, tasking, and execution processes. A surprising amount of that still happens in spreadsheets emailed between people who deserve better tools.

We build the better tools.

Pioneering Evolution has spent over 15 years automating acquisition and finance for federal programs. Our award-winning applications earned their reviews the hard way, through an obsessive emphasis on human-centered design and what our customers describe as meticulous attention to detail. We call our people Pioneers, and we mean it: we are willing to challenge the status quo, embrace unconventional approaches, and blaze a trail for others to follow.

Right now we are building SyncPoint™ and SyncCore™, and we need engineers at the start of their careers to help us do it.

What you would actually be working on:

At Pioneering Evolution, we are building SyncCore — Mission Operating System (Mission OS), designed to connect data, systems, workflows, and decisions across complex mission environments. SyncCore provides the secure, event-driven digital backbone for identity, integration, canonical data, governance, auditability, and interoperability—creating a trusted foundation on which mission capabilities can rapidly evolve. It is the foundation everything else stands on.

Built on SyncCore, SyncPoint is a modular application ecosystem composed of independently deployable modules that address specific operational needs, such as requirements management, budgeting, task planning, resource allocation, execution, and decision support. Real programs, real money, real decisions.

You would join either the platform team or one of the module teams. Both are great places to learn, and we will talk with you about which fits best. You won’t spend your first year watching from the sidelines. You’ll write production code, participate in design discussions, review code with experienced engineers, and gradually take ownership of features as your skills grow.

The stack: C#, .NET 8+, ASP.NET Core on the back end. Angular and TypeScript on the front. PostgreSQL with Entity Framework Core underneath. RabbitMQ for event-driven messaging. Docker, Git, CI/CD, and Azure Government around all of it.

What we actually require:

Here is the honest version, because vague postings waste everyone’s afternoon.

You need

• Software development fundamentals and a working grasp of object-oriented programming.
• Experience with C# or any other statically typed language. Java, Kotlin, C++, Go, TypeScript, Swift — all fine. We are hiring for how you think, not which compiler you have used.
• Familiarity with relational databases and SQL.
• Some understanding of web applications, HTTP, and APIs.
• Familiarity with Git.
• The ability to work a problem systematically when it does not make sense yet, and to say so out loud when it does not.
• Professional experience. Internship, co-op, academic, military, open-source, or serious personal-project work can absolutely demonstrate what we are looking for.
• Prior .NET, Angular, PostgreSQL, Entity Framework, RabbitMQ, or Azure experience. These are on our stack, not on your entry exam. We will teach them.
• Every buzzword in this posting. Nobody has all of them. We would rather hire someone with solid fundamentals and real curiosity than someone who has skimmed all of it and internalized none of it.

Typically 0–3 years of professional experience. If you are further along and this still describes you, apply anyway and we will talk about level.

Who thrives here:

We move fast. We are building something that does not exist yet, on a small and genuinely dynamic team, and we would rather create something special than something merely adequate.

The best thing about starting your career here is the company you keep while doing it. You would be working alongside a lead architect, a chief engineer, and engineers who are very good at this — close enough to watch how they think, ask why, and get a real answer. If the idea of being the least experienced person in a room full of talented people sounds exciting rather than intimidating, you are the person we are looking for.

Clearance, citizenship, and location

• U.S. citizenship is required. No exceptions. This is a federal program requirement and we cannot waive it.
• You do not need an active clearance to apply. An active Secret is welcome. If you do not have one, you need to be eligible for an interim Secret — and we sponsor. We will walk you through the SF-86, the fingerprinting, and the timeline. Plenty of our people started exactly here.
• Hybrid, with a few days a week at our Arlington headquarters at 2550 S. Clark Street. Close to the Metro, close to the Pentagon, close to the customers whose work you are improving.

What we offer:

• $96,000 – $112,000 depending on demonstrated ability and interview performance.
• paid time off
• 10 paid holidays
• medical, dental, and vision insurance
• company-paid life and AD&D
• company-paid short- and long-term disability
• 401(k) with company contribution
• legal assistance
• tuition reimbursement
• continuing education support

And the part that does not fit on a benefits page: you will be one of a handful of engineers on a platform that is actively growing, not employee number four hundred on a maintenance contract. Your commits will ship. Your questions will get answered by the architect who wrote the thing. Your name will be on work that a program office actually uses.

Pioneering Evolution is growing fast. Come grow with us.

Pioneering Evolution is an equal opportunity employer.
