Job summary

Exostar is seeking a hands-on Software Engineer to ship production systems in a FedRAMP/CMMC regulated setting. You will own end-to-end development across cloud-native architectures on Azure Gov, leveraging AI tools, IaC, and CI/CD to accelerate delivery.

The role emphasizes shipping high-quality, secure software while navigating compliance constraints and delivering cross-system improvements. A bachelor’s degree and U.S. citizenship are required.

Qualifications

• 3+ years of recent, hands-on software engineering.
• Track record of shipping full systems, not just features.
• Proficiency in at least two: Angular/TypeScript, .NET/C#, Python, Java.
• 1+ year building cloud-native systems (Azure preferred).
• Comfortable across the stack—infra → backend → frontend.
• Daily user of Claude Code, Copilot, Cursor, Windsurf, or equivalent.
• Clear mental model of where AI excels and where it fails.
• Experience shipping faster and better with AI assistance.

Responsibilities

• Write production code daily across Angular/TypeScript, .NET/C#, Python, or similar.
• Own systems end-to-end: architecture → implementation → testing → deployment.
• Drive IaC, CI/CD automation, and internal tooling to accelerate the team.
• Provide feedback on platform gaps and engineering friction.

Job description

We’re looking for a builder—a high‑output Software Engineer who ships production systems at a pace that resets expectations. Not an advisor. Not a reviewer. A hands‑on engineer whose default mode is writing and deploying code.

You’ll take on the projects that are too ambiguous, too cross‑cutting, or too critical for anyone else: platform migrations, production‑ready prototypes, architectural rebuilds, zero‑downtime replacements, and integrations nobody wants to own. You pick it up, you build it, you ship it.

We operate in a FedRAMP Moderate / CMMC L2 environment serving major defense primes. Compliance is a constraint—not a blocker.

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.
• Own systems end‑to‑end: architecture → implementation → testing → deployment → You 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.
• Deliver projects stuck in backlog: migrations, prototypes, legacy replacements, cross‑system fixes.
• Drive IaC (Terraform, Bicep), CI/CD automation, and internal tooling that accelerates the whole team.

Raise the Bar (20%)

• Your code becomes the reference standard for engineering quality.
• Review quickly, teach through building, pair on complex problems.
• Share AI‑augmented development techniques—prompting, workflows, context strategies.
• Write practical documentation (READMEs, ADRs), not slide decks.

Inform Technical Direction (10%)

• Provide ground‑truth signal on platform gaps, tooling, and engineering friction.
• Evaluate new tech by building with it—real environments, real data.
• Identify and resolve the technical debt that actually slows teams down.

Qualifications:
