Database Administrator

Company Introduction

Since our founding in 2008, Axelspace has been driven by the vision “Space within Your Reach.” We have continuously refined our unique micro-satellite technology with the goal of democratizing space technology to a wider population across the globe.

AxelGlobe started in 2019 to provide a new Earth observation infrastructure by launching multiple micro-satellites for its higher data frequency. In addition to a satellite launched in 2019, we have successfully launched Japan’s first four mass-produced satellites in 2021. We are currently operating a constellation of five Earth observation satellites, capturing images with a 55 km swath every 2 to 3 days, and providing data and solutions.

Building on our experience with our dedicated satellite business, we launched AxelLiner in 2022 to provide a one-stop service for satellite development and operation, helping customers quickly actualize their satellite business. In 2024, we launched our first demonstration satellite, “PYXIS,” bringing our total number of developed and operated satellites to 11.

Additionally, we received the highest award, the Minister of Economy, Trade and Industry Award at the 22nd JAPAN VENTURE AWARDS in 2022, and was selected as part of “Technology Fast 50 2023 Japan” in 2023.

As the world faces pivotal stages in democratizing satellite development and satellite imagery use, we are actively looking for talented individuals who can enjoy the challenges to make a global impact with micro-satellite technology. Hit that apply button and let’s make our vision come true together!

• Strong command of SQL, with experience in schema design and query optimization.
• Familiarity with at least one ORM framework (e.g., SQLAlchemy, Diesel, Entity) and data modeling tools.
• Experience with some of the following: CI/CD pipelines, unit testing, observability tools (e.g., Grafana, Datadog, Prometheus).
• Proficiency in at least one programming language (e.g., Python, Go) for scripting and automation.

Preferred Skills

• Experience in database reliability, predictability and automation.
• Experience in database performance monitoring and query optimization.
• Experience in building tools for observability and testing of databases.
• Japanese language proficiency to communicate about Software development and technical topics.
• Hands-on experience managing cloud-based environments (AWS) in both development and production contexts.
