About The Position

Quantum Space is developing high-performance spacecraft designed for agility, autonomy, and mission longevity in cislunar space. We are seeking a highly skilled Ground Software Engineer II to lead the development, integration, and operational support of software systems that enable spacecraft testing, mission operations, and real-time ground communications. This role is ideal for an experienced software engineer who thrives at the intersection of distributed systems, mission operations, infrastructure, and real-time data processing. You will play a key role in building the software platforms and operational tooling that support spacecraft integration, command and telemetry workflows, and mission readiness throughout the vehicle lifecycle. You will work closely with flight software, AI&T, mission operations, avionics, and systems engineering teams to develop scalable and reliable ground software solutions that support both integration and on-orbit operations.

Requirements

Bachelor’s degree in Computer Science, Engineering, Physics, Mathematics, or a related technical field
5+ years of professional experience in full-stack software development, including deployment to production or operational environments
Strong understanding of networking, data routing, and communication protocols
Experience working with message buses, APIs, and real-time data pipelines
Familiarity with cloud infrastructure and/or equivalent on-premises environments
Hands-on experience with CI/CD pipelines and modern DevOps practices
Proficiency with relational and/or non-relational databases
Understanding of ground system architectures, interfaces, and distributed systems
Strong version-control practices using modern source-control workflows
Experience contributing to requirements development, verification, and traceability
Experience developing and executing software and system-level tests
Proficiency with Linux environments, command-line workflows, and Bash scripting
Strong technical communication skills, including the ability to communicate operational impacts of technical decisions
Strong documentation practices across operational procedures, interfaces, and system architecture
Ability and willingness to support on-call rotations or real-time operational events during critical mission activities
Must be a U.S. citizen, lawful permanent resident, protected individual per 8 U.S.C. 1324b(a)(3), or eligible to obtain the required authorizations from the U.S. Department of State.

Nice To Haves

Experience developing ground segment, mission-control, or spacecraft operations software
Understanding of spacecraft command and telemetry systems
Familiarity with spacecraft operations tools such as Grafana or other monitoring and data-visualization platforms
Experience with Atlassian tools such as Jira and Confluence
Experience with containerization technologies (Docker, Kubernetes)
Familiarity with distributed systems and high-availability architectures
Experience supporting operational or mission-critical environments
Exposure to aerospace, defense, robotics, or autonomous systems domains
Experience with Python, Go, Java, C++, or similar backend technologies

Responsibilities

Build the architecture upon which the ground software will be run
Own major pieces of the architecture end-to-end
Influence coding standards, architecture, and how we operate as a team
Develop, integrate, and operationally support software systems that enable spacecraft testing, mission operations, and real-time ground communications
Build software platforms and operational tooling that support spacecraft integration, command and telemetry workflows, and mission readiness throughout the vehicle lifecycle
Develop scalable and reliable ground software solutions that support both integration and on-orbit operations
Lead end-to-end system development efforts from design through deployment and operational support
