We're Hiring
Vecteur automates space systems engineering from Phase 0 to PDR. We're expanding the team in Q3/Q4 2026 to push the platform from copilot to autonomous agent. If you want to apply frontier AI to one of engineering's hardest domains, we want to hear from you.
Open Roles
AI Engineer
Toulouse, France · Hybrid
Build the agentic AI system that turns a mission statement into a validated spacecraft design. You'll own the full pipeline — prompt architecture, tool orchestration, multi-step reasoning, and physics-informed guardrails that ensure every output is cross-validated against Orekit, SMAD, and NASA SPICE.
What you'll do
- Design and ship multi-agent orchestration across the Phase 0 → PDR pipeline
- Build tool-use and constrained-generation flows that respect orbital mechanics
- Improve evaluation, red-teaming, and regression testing for agent outputs
- Ship production features end-to-end in a small, senior team
What we're looking for
- Strong Python — you've shipped LLM-based systems in production
- Deep familiarity with agentic frameworks, tool-use, and RAG patterns
- Comfortable with ambiguity: small team, fast iteration, high ownership
Space Systems Engineer
Toulouse, France · Hybrid
Encode decades of mission design expertise into Vecteur's physics engine. Your knowledge of orbit mechanics, power budgets, and ECSS processes becomes the guardrails that keep AI outputs physically valid — and the benchmark data that proves it.
What you'll do
- Implement and validate system-level models: sizing, link budgets, thermal, delta-V
- Define acceptance criteria and reference cases against heritage tools (STK, GMAT, Orekit)
- Specify mission architecture constraints the AI must satisfy
- Review and harden the Phase 0 → B2 engineering pipeline
What we're looking for
- 3+ years in mission analysis, spacecraft sizing, or constellation design
- Hands-on with orbital mechanics and at least two subsystem domains
- Comfortable writing Python — not just using GUI tools
Software Engineer
Toulouse, France · Hybrid
Build the platform that 500+ space companies will use daily. Real-time 3D globe visualization, collaborative workspace, streaming AI chat, and an engineering dashboard — all shipped fast with a small team that owns the full stack.
What you'll do
- Ship product features across Vue 3 / TypeScript frontend and FastAPI backend
- Build real-time systems: WebSocket streaming, 3D rendering (Three.js / CesiumJS)
- Own infrastructure: Docker, CI/CD, PostgreSQL, cloud deployment
- Work directly with the founder — high autonomy, fast feedback loops
What we're looking for
- Strong full-stack skills — TypeScript + Python, or deep in one with curiosity for the other
- You care about UX: clean interfaces, fast interactions, zero jank
- Startup-ready: you ship, you iterate, you own outcomes
Business Development
Toulouse, France · Hybrid
Connect Vecteur with the NewSpace operators, defense agencies, and satellite manufacturers who need to move from concept to orbit faster. You'll shape the go-to-market strategy and close the first Enterprise deals.
What you'll do
- Identify and close Pro SaaS and Enterprise contracts across Europe
- Build relationships with NewSpace companies, primes, and defense agencies
- Run product demos, qualify leads, and manage the full sales cycle
- Feed market insights back into product roadmap
What we're looking for
- Network in aerospace, defense, or deep-tech B2B — you know the buyers
- Experience selling technical products to engineering teams
- Entrepreneurial: you build the playbook, not follow one
Why Join Vecteur
Compress an Entire Industry
What takes 2–4 years and a team of 10+ senior engineers, Vecteur does in 20 minutes. You'll build the tools that make it possible.
AI Grounded in Physics
Not prompt engineering — real equations, real orbits, real spacecraft. Every output is cross-validated against NASA SPICE, Orekit, GMAT, and CNES heritage tools.
Your Work Ships to Orbit
The constellations designed on Vecteur will define connectivity, defense, and Earth observation for decades. This isn't a dashboard — it's infrastructure for space.
Early Team, Full Ownership
Small team, big mission. You'll work directly with the founder, ship features end-to-end, and shape the company — not just the product.
Toulouse — Capital of Space
Home to Airbus Defence & Space, CNES, Thales Alenia Space, and 300+ space companies. The talent and the customers are here.
Ideas & Optimism
We move fast, own outcomes, and believe the future is ours to build. Problems are puzzles — not obstacles.
