Job summary

Exostar is seeking a hands-on Software Engineer to ship production systems in a regulated environment. You will own end-to-end delivery—from architecture to deployment—across a modern stack including Angular/TypeScript, .NET/C#, and Python, with Azure Gov and FedRAMP/CMMC considerations.

You’ll work on migrations, prototypes, and tooling to accelerate delivery, using AI-assisted coding tools and IaC. This is a fast-paced, security-conscious role in the Defense/regulated SaaS domain.

Qualifications

• 3+ years of hands-on software engineering.
• Proven track record shipping full systems end-to-end.
• Proficient in at least two: Angular/TypeScript, .NET/C#, Python, Java.
• 1+ year building cloud-native systems (Azure preferred).
• Experience in regulated environments (FedRAMP, CMMC, ITAR, SOC2, HIPAA).

Responsibilities

• Build and ship production code across Angular/TypeScript, .NET/C#, Python, or related stack.
• Own end-to-end architecture, implementation, testing, and deployment.
• Drive IaC (Terraform, Bicep) and CI/CD automation.
• Improve engineering maturity through documentation and mentoring.

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

You are a great fit for this role if you:

You are a Builder

• 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; Azure Gov a plus).
• 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.
• Demonstrated examples of shipping faster and better with AI assistance.

Judgment & Engineering Maturity

• Thrives in ambiguity; makes reasonable assumptions and ships.
• Strong but flexible opinions on architecture and developer experience.
• Experience building in regulated environments (FedRAMP, CMMC, ITAR, SOC2, HIPAA).

Bachelor’s degree in computer science, Engineering, Information Systems, or a related technical field.

U.S. Citizens only- Due to customer requirements, U.S. Citizenship is required. Ability to gain and maintain Trusted Role is required

Preferred Qualifications

You are exactly who we are looking for if you:

• Azure Government (IL2/IL4/IL5), Entra ID, PIM, managed identities, Zero Trust.
• IAM, credentialing, PKI, or federated identity background.
• Experience building dev tools, internal platforms, or shared infra.
• Aerospace & Defense, Life Sciences, or other regulated SaaS environments.

Why Exostar

• AI-native engineering: Claude & Copilot integrated across the org with leadership backing.
• Mission impact: Secure collaboration infrastructure for the Defense Industrial Base.
• Real technical constraints: FedRAMP Moderate, CMMC 110/110, Azure Gov multi‑tenant SaaS.

The pay range for this position is $85,000k - $105,000k/yr; however, the final compensation will be determined based on factors including experience, skills, qualifications, and location.

• health insurance (medical, dental, vision, prescription, Basic Life & AD&D insurance, EAP, Flexible Spending Accounts, 401(k) matching, flexible time off and sick leave)
