Job description

【Position】 Senior Ground Platform Engineer(Senior SRE)

【About Job】 About Dept. and Unit The Data Production Department operates Synspective’s proprietary small SAR satellites (“StriX” series), produces imagery from satellite data, and manages data delivery. Within this department, the Ground Platform Engineering Unit (GPE Unit) designs, develops, and operates the entire cloud platform responsible for core functionalities such as orbit operations, ground station communication, and image generation from observation data. Responsibility We are seeking a cloud engineer responsible for the design, development, and maintenance of our cloud platform, as well as the construction of a Disaster Recovery (DR) site. Details of work

● Design, build, and operate satellite ground system infrastructure in cloud environments using Terraform, including the design, deployment, and management of Kubernetes clusters, as well as improving development productivity through CI/CD pipeline optimization.

● Lead the design, validation, and implementation of a Disaster Recovery (DR) site architecture, driving the project in collaboration with cross-functional stakeholders.

● Plan and implement security enhancement measures and ensure

 

 

 

Job Discription

compliance with relevant regulatory and organizational requirements. ● Strengthen monitoring and alerting systems to support large-scale

satellite fleet operations. ● Continuously improve operational efficiency through the use of AI

agents for automation, cost optimization, and performance tuning. Selling points of this role

● Work on mission-critical systems running primarily on Google Cloud. ● Be part of a company actively promoting AI utilization, integrating AI

agents (Claude Code, Cursor, Gemini) to tackle social and business challenges through the intersection of satellite and AI technologies.

● Gain hands-on experience building systems with unique requirements that differ from typical web applications.

The space industry is undergoing a major shift—from government-led initiatives to private-sector innovation. With Japan’s commitment to investing one trillion yen over ten years in its national space strategy fund, expectations for private space companies are rising.

Synspective aims to build a 30-satellite constellation by the late 2020s, giving you the opportunity to work at the forefront of Japan’s commercial space industry. Because few companies develop and operate both satellites and ground systems in-house, this offers a rare chance to work at the leading edge of the space business. Unlike typical vendor-led projects, our engineers design, develop, and operate their own end-to-end systems—allowing you to experience system evolution firsthand in a short time.

You’ll also collaborate with diverse experts across disciplines and tackle challenging goals, building skills essential for success in the global technology landscape. （Scope of Change） All company operations
