About Department and Unit

The Data Production Department is responsible for satellite operations, image data production, and distribution of data products from our proprietary small SAR (Synthetic Aperture Radar) satellites, the "StriX" series.

Within this department, the Satellite Operation Planning Unit is in charge of creating operation plans for our satellites, generating and registering command sequences to the satellite control system based on these plans, as well as managing data necessary for smooth operations.

Responsibilities

In this position, you will join the Satellite Operation Planning Unit within the Data Production Department, which is responsible for developing and operating the Spacecraft Control Subsystem for our small SAR satellite constellation, the "StriX" series. The Spacecraft Control Subsystem is a core component of our satellite operations, and our top priority is to ensure that the system operates reliably at all times.

Job Details

As the Spacecraft Control Subsystem is an in-house system, we are not only responsible for its development but also its ongoing operation and enhancement. The Spacecraft Control Subsystem is responsible for creating operational plans for our satellites, generating command sequences, and calculating essential information such as the past and predicted positions and velocities of our satellites to support the planning process.

In this position, you will be involved in developing orbit determination and propagation applications as a backend engineer. You will work closely with our orbit determination team to achieve highly accurate orbit determination and propagation with maximum efficiency (e.g. minimizing computation time and system load, and ensuring the application is easy to maintain). With plans to launch many satellites in the future and a wide variety of orbit determination requirements, you will play a key role in meeting these demands and expanding our business capabilities.

Key Benefits of This Role

We are already operating several satellites in orbit, and the number of satellites is expected to increase rapidly in the near future. The Spacecraft Control Subsystem is essential to our daily operations, and we rely on it to manage our satellites effectively. In this role, you will contribute to the development, operation, and management of such a critical system. As we strive to achieve even greater operational stability with less manual intervention, you will have the opportunity to demonstrate and further develop your skills by addressing these challenges.

By maintaining the Spacecraft Control Subsystem, which interacts with both our data platform (used as the customer-facing frontend) and our Data Processing Subsystem (which generates SAR products), you will be working at the very core of our business.

The quality and efficiency of our orbit determination and propagation have a direct and significant impact on the quality of our products. Your work will contribute directly to enhancing product quality and, ultimately, to increasing customer satisfaction.

Minimum qualifications

  • At least 3 years of experience in system development on GCP or AWS.

  • At least 3 years of software development experience using MATLAB.

  • Strong experience in software development using at least one of the following programming languages:

    • Golang

    • Python

    • C++

  • Experience working as part of a development team of 3 or more members.

  • Comfortable communicating in English, both written and spoken.

  • Able to commute to our Tokyo head office (Kiyosumi Shirakawa, Tokyo) 2-3 days per week.

Preferred requirements

  • Experience in developing flight dynamics systems for spacecraft (preferably for low Earth orbit).

  • Experience in developing orbit determination systems for spacecraft (preferably for low Earth orbit).

  • Basic knowledge of mathematics and physics as applied to orbit determination.

  • Comfortable communicating in Japanese, both written and spoken.

Work location

Office: Headquarters

Address: 3-10-3 Miyoshi, Koto City, Tokyo
