Senior Software Developer

Senior Software Developer

Join us as a Senior Software Developer and help power the mission systems that keep national security space operations running. In this role, you'll be responsible for identifying and autonomously implementing ideas and solutions as it relates to the design and delivery of mission-critical ground segment software that connects satellites, ground networks, and operators in real time. You'll be embedded in a National Security Missions team focused on full-lifecycle ground architecture, working shoulder-to-shoulder with experts across software, systems, and operations. Every day, you'll tackle complex, real-world problems whose solutions directly influence mission outcomes and protect critical national interests. If you want to build cutting-edge space technologies in a fast-paced, high-visibility environment where your work truly counts, this role puts you at the center of the action.

This position requires an active Top-Secret/SCI Clearance (A U.S. Security Clearance that has been active in the past 24 months is considered active).

What You'll Do:

• Support the Design & Delivery of the Ground System : Collaborate with a multidisciplinary team to design, build, and deploy a state-of-the-art, highly resilient Ground System. Support end-to-end development, from system architecture and software design to integration, test (I&T), and operational deployment.
• Support CI/CD & Deployment Strategy : Build, configure, and maintain CI/CD pipelines and build environments to ensure secure, consistent, and repeatable software deployments across mission networks.
• Manage Software Releases : Play a key role in planning, coordinating, and executing software releases, ensuring strict alignment with stakeholder timelines, program schedules, and budget constraints.
• Ensure Rigorous Process & COTS Integration : Adhere to and systematically refine established protocols for change control, risk management, prioritization, and COTS (Commercial-off-the-Shelf) integration. Contribute your technical depth to formalize robust build/test procedures and process documentation.
• Track & Trace Execution : Independently maintain accurate, up-to-date issue tracking, feature documentation, and project status across the development lifecycle utilizing Atlassian tools.
• Lead Technical Communication : Translate complex ground segment concepts into clear, concise briefings, documentation, and written reports tailored for both highly technical engineering teams and non-technical government stakeholders.
• Apply Technical Expertise : Provide timely, well-informed technical input within your area of expertise to support stakeholder inquiries, system development, and cross-functional efforts.
• Innovate & Solve : Autonomously identify and implement robust software solutions to overcome complex architectural challenges, delivering secure, customer-driven mission capabilities.

What You'll Need to Succeed:

Required Qualifications

Preferred Qualifications

• Experience in satellite operations ground segment environments, particularly in network management or packet-level data handling
• Familiarity with the Atlassian tool suite (Jira, Confluence, Bitbucket) in a professional development setting

Things That Would be Great if You Brought to the Table:

• Experience with Flight Dynamics, in the context of satellite missions, pertains to the function that determines, predicts, and controls a spacecraft's orbit, attitude, and trajectory over its lifetime, including the maneuvers needed to achieve and maintain the desired flight path.
• Experience with Mission planning, in the context of satellite ground and space systems, is the set of processes, tools, and rules used to translate mission objectives into time-ordered, constraint-compliant timelines of spacecraft, payload, and ground activities (including data collection and routing opportunities) across the full mission lifecycle.
• Experience with Network Management pertains to continuously supervising and controlling all links and nodes across the space segment (LEO/MEO/GEO satellites and inter-satellite links) and the ground segment (gateways, teleports, user terminals, terrestrial backhaul).
• Containerization & Orchestration: Kubernetes, Docker, Podman, ArgoCD
• CI/CD Pipelines & Artifact Management: GitLab, JFrog Artifactory, Bitbucket
• Additional Programming Languages: C++, TypeScript, Perl
• Data Formats & Query Languages: XML, JSON, SQL
