Vacant job

We are looking for a Software Development Lead for Leia, our easy-to-use mission analysis tool. The software's core functionality is currently in beta testing, and your role will be to lead the development towards a fully released product and incorporate new capabilities from that point onward.

Our flight dynamics team codes the algorithms. You will build the product around it, owning the architecture end-to-end: API, front-end, database, containerization, and deployment.

This is the first dedicated software engineering hire at Vinterstellar and a key position. We foresee that the software team will grow under the leadership of the person filling this role.

WHAT YOU WILL WORK ON

• Back-end: Expose the analytical engine as a REST API.
• Front-end: Mission configuration, results display, and dashboards.
• Database design, user management, and audit trail.
• Containerization, CI/CD, and deployment (cloud and self-hosted).
• 3D orbit visualization, building on our existing online orbit calculator.
• Report generation and structured data export.
• Over time: Natural language query features, additional web services, and data interfaces for space situational awareness.

WHAT WE ARE LOOKING FOR

Mid-level candidate with 3–5 years of experience building production web applications.

• Willing to work across the full stack as the primary builder in a small team.
• Strong Python skills; experience with FastAPI, Django, or similar frameworks.
• JavaScript or TypeScript with a modern front-end framework (React preferred).
• Comfortable with databases, Docker, and basic DevOps.
• Curiosity about space, scientific computing, or complex engineering domains — you do not need to be a rocket scientist, but you should want to understand what the platform does.

USEFUL BUT NOT REQUIRED

• Familiarity with Three.js, WebGL, or data visualization libraries.
• Interest in LLM integration and AI-assisted interfaces.
• Experience with CI/CD pipelines and infrastructure-as-code.

REQUIREMENTS

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