Ground Software Engineer Senior - (Security Clearance; Field-Based)
About The Position
We are looking for a Senior Full Stack Software Engineer who thrives working independently and is passionate about building software that pushes the bounds of what's possible. Our software is a modern web-based application (React/TypeScript, C# .NET) with a microservice infrastructure (Docker, Kafka, REST) that operators use to monitor and control constellations of spacecraft across several active missions. In this role, you will be embedded at or near a Mission Operation Center (MOC) local to you, serving as the primary technical point of contact for that facility. You'll operate with a high degree of autonomy — often as a team of one or two — while staying closely integrated with our primary office in Denver, CO for feature development, technical direction, and longer-term project work. This is not a traditional office role. You must be comfortable owning problems end-to-end without immediate peer support, communicating proactively across time zones, and context-switching between hands-on operational support and collaborative product development. About the Work You'll work closely with satellite operators, customers, and the Denver engineering and UI/UX teams to tackle hard problems like: Collision avoidance, conjunction analysis, and orbit-raising maneuver planning Operation center failover and continuity of control Cross-satellite network maintenance and space-to-ground link management Ground station contact scheduling and pass optimization Multi-vehicle mission coordination Your work will be deployed in a MOC where it will directly support active missions in orbit. Prior space-industry experience is not required.
Requirements
- Bachelor's degree in Computer Science or related field
- 6+ years of full-stack software engineering experience
- Active Secret security clearance
- Demonstrated ability to work independently with minimal day-to-day supervision and comfort operating as a primary technical resource without immediate peer support
- Strong remote collaboration skills with experience working effectively as part of a geographically distributed team, including async communication and documentation habits
- Demonstrated ability to independently troubleshoot and resolve deployment failures, runtime issues, and environment-specific defects, including in isolated and/or air-gapped environments without immediate escalation paths
- Deep expertise in strongly typed backend languages, particularly C#, including multithreaded applications, concurrency patterns, and near-realtime data handling
- Experience designing and consuming REST APIs at scale
- Experience with SQL databases, including schema design and query optimization
- Experience with Git in a collaborative, multi-contributor environment
- Willingness and ability to provide on-call support for operational facilities
- Ability to travel to Denver, CO for onboarding, training, and periodic team visits
- Strong verbal and written communication skills, including presenting technical concepts to non-technical audiences
- Proven ability to thrive in a fast-paced, mission-driven environment with ambiguous requirements
Nice To Haves
- Eligibility for Top Secret security clearance
- Proficiency in modern React and its core principles, including component architecture and performance optimization
- Proficiency with common front-end tooling such as Yarn, Babel, or Material-UI
- Experience working across a polyglot stack including Python, Kafka, and InfluxDB
- Experience with modern state management tools such as TanStack Query
- Experience designing and executing forward and backward compatible database migrations and deployment strategies in live production environments
- Experience with feature flagging strategies, including gradual rollouts, environment-based toggles, and flag lifecycle management
- Experience with container-based installation and deployment strategies, including Docker and CI/CD pipeline integration
Responsibilities
- Serve as the primary technical resource for your local MOC, providing direct support to operators and resolving issues with a high degree of independence
- Provide on-call support for mission-critical operations by responding to incidents and escalations at your assigned facility
- Integrate remotely with the Denver ground software teams for feature development, longer-term technical work, sprint ceremonies, and cross-team coordination
- Develop key user-facing features to support both current and future missions using TypeScript, React, C#, MSSQL, InfluxDB, Kafka, and Python
- Translate designs and requirements into high-quality, maintainable code
- Build reusable components, shared libraries, and scalable services for use across the platform
- Engineer algorithms and business logic to promote scalability and automation
- Write unit and integration tests, including tests against simulation tools to validate behavior against realistic mission scenarios
- Write documentation for internal users and customers
- Act as the technical face of the engineering team at your local site, building strong relationships with operators and customers
- Mentor junior engineers (on-site or remote) through code reviews, pair programming, and design discussions
- Contribute to sprint planning, technical scoping, and cross-team alignment with the distributed engineering organization
- Communicate proactively and clearly with remote teammates. Written communication and async collaboration are essential in this role
- Help establish and advocate for engineering best practices across the team
