About The Position

NetServices (NSI) is an IT services firm with a long-standing reputation for delivering high-quality, cost-effective solutions to drive lasting results. Now operating as a subsidiary of Synergy ECP, NSI continues to stand out in a crowded contracting landscape through its agility, strong customer focus, and commitment to retaining exceptional talent. By taking on challenging IT initiatives, we cultivate our talent and are continually evolving through our partnerships with clients. Our close-knot team of highly cleared engineers, analysts, and program managers represent some of the best talent locally available. Full Stack Developer TS/SCI Required | Suitland, MD (Hybrid) | Immediate Start The Opportunity We are standing up a small, elite development team to deliver cloud-native applications that directly support client operations. This is a focused, high-impact team where every engineer’s contribution is visible and consequential. We are looking for a Full Stack Developer who combines deep Python expertise with genuine frontend craftsmanship, thrive in classified environments, and bring the kind of disciplined engineering mindset that produces secure, maintainable systems under real operational pressure. Location: Hybrid, 2–3 days per week on-site in Suitland, Maryland Start: Immediate Team: 2–3 developers reporting to the technical lead Stack: Python/Django, React/Next.js, PostgreSQL/Aurora, AWS (multi-partition), Terraform, GitLab CI/CD, Keycloak What You Will Do You will design and deliver complete applications; from database schema to API layer to the interface a mission user opens every morning. The team supports an established platform application while simultaneously standing up pilot solutions and custom MVPs for emerging requirements. On any given week, you might be extending a Django-based API gateway, building a new React dashboard for an operational workflow, writing migration scripts to bring legacy data into a modern PostgreSQL schema, or wiring up Keycloak authentication for a new service. This is full stack work in the truest sense. We need engineers who move fluidly between backend logic and frontend polish, who care as much about a clean component hierarchy as they do about a well-indexed query, and who understand that in classified environments, every design decision carries security implications. The team deploys across multiple AWS partitions and classification levels. You will work with Terraform for infrastructure, GitLab for source control and CI/CD, and AI-assisted development tooling as a standard part of your workflow — not as an experiment, but as an expectation.
