Lediga jobb Vinterstellar AB i Stockholm

We are building software that tracks what moves in orbit and flags what matters. You will be working with orbit determination in the intersection between orbital mechanics, mission operations, and intelligence.
While you will touch upon many of our projects, your primary work will be to lead the technical work on our LSSA-Pilot project, developing the algorithms, data pipelines, and operational framing that make space situational awareness usable for non-engineers. You will work with our flight dynamicsists, who know the orbital mechanics. Your job is to translate sensor data into orbit knowledge and on to Space Situational Awareness. This role grows naturally toward technical leadership.


WHAT YOU WILL WORK ON
Orbit determination, object tracking, and proximity analysis algorithms
Integration of external space object catalogs and data sources
Conjunction screening, collision avoidance computation, and launch safety analysis
Defining CONOPS-level requirements: what operational users need to see, when, and why
Collaboration with research and industry partners in the SSA domain



WHAT WE ARE LOOKING FOR
Mid-to-senior candidate, 5–8 years of experience. Operational instinct comes from years in mission rooms; we need seniority here.
Experience with how real missions are operated — not just the physics, but the process
Background in controls engineering, preferably applied to orbital mechanics and flight dynamics
Ability to bridge the gap between rigorous analysis and what decision-makers need to act on
Strong programming skills in Python
Understanding of orbit determination or propagation techniques
MSc or PhD in control engineering, aerospace engineering, physics, applied mathematics, or equivalent



USEFUL BUT NOT REQUIRED
Experience with space object catalogs, TLE formats, or conjunction data messages
Familiarity with CCSDS standards
Interest in defense applications
Background in mission control, flight operations, or CONOPS development



REQUIREMENTS
Fluent in English; Swedish is a plus
EU or EES citizen

Are you ready to apply your skills to an exciting space technology project? At Vinterstellar, you’ll have the opportunity to help pave the way to the Moon at one of Stockholm’s leading space startups. If you enjoy problem-solving, interdisciplinary collaboration, and working toward clear goals—keep reading!
We are offering a unique summer job for students in aerospace engineering, mathematics, programming, software development, or communication design. This is a chance to work in an environment that values independence, creativity, fast decision-making, and rapid implementation. You'll receive guidance from experienced experts while gaining hands-on experience in product and business development within the space and aviation sector.
Work can be done remotely or from our office on Drottninggatan in Stockholm.


About the Project
We’re looking for two students to develop a web-based tool for orbit optimization—turning a mathematical model into an intuitive, user-friendly interface. The goal is to showcase our company’s expertise while providing real value to users.


Your Mission
Programming – Develop an interactive model for transferring an elliptical orbit to a circular geostationary orbit, based on an existing algorithm.
UI/UX & Web Development – Design an intuitive, visually appealing interface where users can input satellite parameters and easily visualize the resulting orbit.
Deployment & Accessibility – Integrate the tool into a WordPress-based website, making it publicly available.



Who We’re Looking For
A student in aerospace engineering, applied mathematics, or computer science, with an interest in programming and satellite simulation.
A student in frontend development, communication design, or UX design, with an interest in programming and experience in creating interactive web-based interfaces.

Since this project requires two complementary skill sets, we are looking for a team of two. Together, we will create a structured project plan. Close collaboration is essential, so both candidates should have a basic understanding of programming and software development, even if their expertise differs.
We value teamwork, creativity, and a solution-oriented mindset. Innovation comes from daring to experiment, learning from mistakes, and finding new ways forward.
