Stella Technologies LLC is a lean startup that delivers model based systems engineering, digital cyber engineering, and modeling, simulation, and analysis for complex technical programs. We help teams connect requirements, architecture, and verification in a way that stays coherent as systems change, and we build the tooling and automation needed to keep engineering work traceable and usable over time. Our work includes building model driven workflows, simulation and digital twin environments, and cyber informed engineering approaches that support early testing, trade studies, and evidence based decisions. Stella is intentionally small and execution focused, staffed by highly capable individuals who take ownership of difficult tasks and deliver practical, working solutions. We believe human time is the world's most valuable asset and the greatest waste is squandering brilliant minds on repetitive, automatable tasks. We build systems that eliminate waste, freeing people to focus on creative, strategic, and complex challenges. Incumbency is a bug, not a feature. We build with open standards and straightforward engineering. No proprietary lock-in, no opaque systems.

What You'll Do

• Build platform services and platform-hosted micro-applications used for cybersecurity workflows
• Design and maintain backend services, APIs, data models, and frontend applications that support Cyber Assessment and Authorization activities for weapon systems
• Develop workflow-driven software for intake, evidence capture, task routing, review, reporting, and related mission processes
• Integrate applications with Azure services, identity systems, data stores, and internal platform capabilities
• Work with containerized deployments, CI/CD pipelines, and cloud-hosted environments to ship software reliably
• Collaborate with cloud, platform, and domain teams to translate operational needs into usable software
• Write clean, testable, maintainable code and participate in code reviews, troubleshooting, and iterative product development
• Contribute across the stack in a small-team environment where priorities and contracts evolve

What We're Looking For

• 5+ years of hands-on full stack software development experience.
• Strong backend development experience with Python, Node.js, or similar modern service frameworks.
• Solid frontend experience with React or comparable web application frameworks.
• Experience designing and integrating REST APIs, data models, and user-facing applications.
• Experience with databases such as MongoDB, PostgreSQL, or similar application data stores.
• Familiarity with Git, Docker, CI/CD workflows, and cloud-hosted application deployments.
• Comfortable working across platform services and application-level development in the same role.
• Strong communication skills and the ability to work closely with domain experts, infrastructure engineers, and product stakeholders.
• US Citizenship required; active Secret clearance preferred, must be able to obtain.
• Startup mindset: comfortable with ambiguity, evolving priorities, and wearing multiple hats.

Nice to Have

• Experience building software for an internal platform, PaaS, or shared application environment.
• Familiarity with Go.
• Familiarity with Azure, GitLab CI/CD, Kubernetes, or Helm.
• Experience with OAuth 2.0 / OIDC, Entra ID, or similar identity and access patterns.
• Prior public sector, DoD, cybersecurity, or cleared-environment experience.
• Knowledge of CMMC, NIST 800-171, RMF, or related compliance and authorization frameworks.
