Ground Systems Engineer (Developer)

Team: Test & Flight Management

Location: Tokyo, Japan

Commitment: Full-time (Regular)

Workplace Type: hybrid

Why this role matters?

As a Ground Systems Engineer, your work directly enables communication with the spacecraft and underpins every phase of mission test and execution. You play a pivotal role in ensuring that missions are conducted safely, reliably, and efficiently—designing and maintaining the infrastructure, software, and operational workflows that make real-time spacecraft operations possible. Your contributions not only ensure mission success, but also streamline operations and empower flight teams to perform at their best.

Key responsibilities

Ground Segment Design, Infrastructure and Development
• Collaborate with customers and internal stakeholders (System and Subsystem Engineers,AIT, Mission Operations, etc.) to gather requirements, and design, develop, document,procure, maintain, and deploy ground segment systems.
• Design, develop, and maintain cloud-native ground segment software applications andmicroservices, including mission control systems, automation tools, and data pipelines.
• Design, deploy, and maintain cloud infrastructure on AWS, including containerisedenvironments using Docker and Kubernetes, ensuring reliability, scalability, and security ofground segment services.
• Implement and maintain CI/CD pipelines (GitLab, Ansible) for continuous delivery of groundsegment software components.
System Integration & Testing
• Oversee the integration of software components within the virtual infrastructure hosting theground segment, ensuring proper interfacing with spacecraft systems and external groundelements (e.g., EGSE, PIL components).
• Develop and execute test plans, procedures, and configurations, including end-to-end validation of communication and control links.
• Support V&V activities across the ground segment.
Operations Support
• Develop, test, and validate operational procedures.
• Participate in training activities and mission rehearsals to achieve certification for on-consoleoperations.
• Own and maintain Ground-to-Ground Interface Control Documents (ICDs), and contribute to Space-to-Ground ICDs with ground station providers.
• Support on-console operations, including 24/7 shift work and on-call duties during criticalmission phases.

Required skills

• Language: Professional level English (written and verbal); Japanese is a plus.
• Experience: 3+ years of experience in ground systems engineering or software development for space missions (LEO, MEO, Deep Space, etc.).
• Cloud & Infrastructure: Hands-on experience with AWS and container orchestration using Docker and Kubernetes.
• Software Skills: Proficiency using Python and Bash; strong expertise in CI/CD tools such as Ansible, Gitlab.
• Operating systems: Solid knowledge of Linux; familiarity with Windows environments.
