Software Quality Assurance Engineer (Manual)
Help us make sure that the software supporting space operations works reliably, accurately, and as expected - before it reaches our customers.
About Sybilla Technologies
At Sybilla Technologies, we are on a mission to let the world see what happens in space — clearly, reliably, and on time.
In a domain where objects travel at 24,000 km/h and a single unseen fragment can destroy a satellite or endanger a crew, visibility is everything. We transform that responsibility into action, building systems, software, and services that safeguard the future of global space operations.
Born from a passion for astronomy, engineering, and exploration, Sybilla has grown from a small, bootstrapped startup into a recognized European space-tech company. We work across Space Traffic Management, Space Surveillance & Tracking, and Space Operations, combining advanced optical systems, software, automation, and data.
Our technologies help governments, defense organizations, space operators, and other customers understand what is happening in orbit and make better, more informed decisions in an increasingly complex space environment.
Today, we are a growing international team of astrophysicists, engineers, software developers, analysts, project managers, and other specialists working together across Europe and beyond.
About the role
As a Software Quality Assurance Engineer (Manual), you will take ownership of the functional quality of assigned features and releases. Your role will be to make sure that delivered functionality meets business requirements, acceptance criteria, and user expectations.
You will work closely with Development and Product teams, turning requirements into structured test scenarios, identifying defects, validating fixes, and providing clear feedback throughout the development process. You will also help us make our QA practices more consistent, transparent, and effective as the company grows.
This is a hands-on role for someone who is comfortable working independently, investigating how systems behave, asking questions when something is unclear, and taking responsibility for the quality of their work. You will work primarily with manual testing, while also having the opportunity to contribute to testing non-LLM machine learning models if you have the relevant experience.
