Company Description
Pre-seed airport operations AI startup backed by Entrepreneur First (EF)
Job Description
As the first engineering hire, you will build the technical core of a real-time orchestration platform for airport ground operations. You will design systems that reconcile noisy live signals into a canonical operational state, automating complex resource allocation and conflict resolution to prevent the cascading delays that cost the aviation industry billions annually.
Location
London, UK
Why this role is remarkable
- Solve high-stakes systems problems like real-time state machines and dependency-aware recomputation for live airport environments rather than building generic CRUD apps.
- Join a founding team with deep operational expertise from Formula 1, the FIA, and Lufthansa, backed by the EF Fall 2025 cohort.
- Gain massive employee #1 ownership, working directly with founders to move from architecture to implementation while seeing your code drive physical operations on the airport ramp.
What You Will Do
- Design and implement real-time data processing pipelines and conflict detection state machines using TypeScript, Python, and Convex.
- Build deterministic allocation and assignment logic that continuously recomputes the best use of staff and equipment under volatile real-world constraints.
- Develop causal graph orchestration systems to handle delay propagation and multi-tenant operational logic across complex task windows.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
The ideal candidate
- Has 2-3 years of experience in high-growth startups building correctness-sensitive backend systems, event-driven architectures, or workflow engines.
- Demonstrates a strong grasp of algorithms and invariants, with the ability to own the full lifecycle of complex systems from architecture to production debugging.
- Is a prolific builder with a portfolio of side projects or open-source contributions who thrives in ambiguous, founder-level ownership environments.
