Job Description

#

Your mission

Your mission is to

develop and maintain a scalable, asynchronous backend

that powers OKAPI:Orbits’

end-to-end solutions

across

mission design, Space Situational Awareness (SSA), Space Traffic Management (STM)

,

Flight Dynamics (FD)

and

Space Traffic Coordination (STC)

— supporting the

full lifecycle of satellite operators

.


You design and implement

robust Java-based microservices

that process and distribute large volumes of orbital and telemetry data, enabling reliable APIs and automation pipelines.

You work on the systems that

allow satellite operators and space agencies

to analyse, coordinate, and protect their missions in an increasingly congested space environment.


Research shows that women are less likely than men to apply for a position unless they meet 100% of the listed requirements. Please know that if it’s your case — but you are passionate about

space technology

,

building reliable software

, and

contributing to a more sustainable space environment

— we strongly encourage you to apply.

OKAPI:Orbits

already brings together a highly diverse team, and we actively continue to strengthen this diversity, as research consistently shows that

heterogeneous teams achieve higher performance and drive innovation

About us

OKAPI:Orbits is at the forefront of space sustainability, addressing some of the most pressing challenges of the space industry: the growing problem of crowded orbital regimes, and the need for more efficient satellite operations. We're providing end-to-end solutions that help various space industry players cover their Space Situation Awareness (SSA), and Space Traffic Management and Coordination (STM & STC) needs. We are committed to safeguarding space missions and access to space for all humanity. Join us on our mission.



Last but not least, we would like to share with you that research shows that women are

less likely to apply for a position unless they meet 100%

of the listed requirements.

Please know that if it’s your case — but you are passionate about space technology, building reliable software, and contributing to a more sustainable space environment — we strongly encourage you to apply.

OKAPI:Orbits already brings together a highly diverse team, and we actively continue to strengthen this diversity which allows us to achieve higher performance and drive innovation.
