As a member of the Data Production Department, your role will involve contributing to the development and operation of the spacecraft control subsystem for the 'StriX' series of small SAR satellites. This subsystem is responsible for operating our satellite constellation.

This subsystem has three main roles: creating operation plans for our satellites, generating commands for them, and calculating specific information about their orbits. As we are developing this system in-house, we will also be responsible for operating it and adding new functions in the future. This position aims to introduce/update quality assurance activities to the system.

The spacecraft control subsystem is crucial for our daily satellite operations, and you will be involved in its development and maintenance.

You will also be involved in developing and maintaining the subsystem at the core of our business. The subsystem interacts with our data platform, which is used for the frontend to customers, and the data processing subsystem that generates SAR products.

We plan to rapidly expand our satellite constellation and require more stable satellite operation with less personal effort. You can showcase your skills and grow by achieving these requirements.

Synspective is a space start-up that provides business solutions based on data from satellites. Founded in 2018, they develop and operate their own synthetic aperture radar satellites.

While most start-ups in the Earth Observation sector are limited to one area such as data analytics or the development of satellite hardware, Synspective handles everything from developing satellites to data analytics to building solutions for clients based on this infrastructure.

With an emphasis on data, Synspective aims to become a true one-stop-shop player for solutions based on satellite data. With SAR satellites that apply the results of the Japanese Cabinet Office’s “ImPACT” program, Synspective’s goal is to create a platform capable of frequent data collection, and sell or use that data to offer solutions for government and business entities.

Synspective’s culture is defined by their concept of “Human Centered Design for Company”. They’re striving to build a strong organization that relies on the performance of each individual. To that end, they provide a flexible environment where specialists can work autonomously, empowering members to work whenever it enables them to do their best work.

Since the company is entering into a market that’s still developing, optimizing for the performance of each individual is essential for the success of the company’s business. They also want to support members in expressing their own ideas and hypothesis since they know that the satellite business still has many open questions.

Synspective is an organization full of highly-motivated specialists, so each full-time employee is on a 6-month contract. Members’ performance is evaluated every six months, and those who’ve made major contributions are rewarded for their effort. This also helps maintain an environment where everyone can work freely and independently among people focused on improvement and growth.

Synspective's policies during COVID-19 are as follows:

  • During COVID-19 all of their members are working from home. *They’ve opened up hiring for overseas candidates for a few positions.
  • Synspective was already working remotely before COVID-19 for most roles.
