Job Title: Junior Software Developer

Company Description: Joinkyber.com โ€“ Pre-seed EF Fall 2025 AI startup

Job Description:
As the first engineering hire at Kyber, you will build the real-time AI decision-making platform that orchestrates airport ground operations. You will develop fault-tolerant agentic systems to replace manual spreadsheets and radio calls, owning technical direction while generating critical data to predict and prevent global aviation delays alongside ex-F1 and Lufthansa founders.

Location: London, UK

Why this role is remarkable:

  • Join as the first engineering hire with massive ownership, working directly with founders from F1, FIA, and Lufthansa to disrupt commercial aviation

  • High-impact work building the industry's first real-time AI decision engine for chaotic airport environments, moving beyond pre-seed with EF Fall 2025 backing

  • Opportunity to build a category-defining product from scratch, gaining unparalleled experience in production-grade agentic AI and event-driven architecture

What you will do:

  • Design and implement real-time, fault-tolerant agentic systems that airport teams trust to manage live flight operations and ground logistics

  • Build and scale a full-stack platform using Python and TypeScript to process chaotic operational data into high-accuracy delay predictions

  • Iterate rapidly on product features through direct customer feedback, owning the technical lifecycle from initial pilot programs to production deployment

The ideal candidate:

  • High-agency developer with 2โ€“3 years of experience at a rigorous company and a proven track record of shipping complex side projects

  • Strong technical foundation in Python, TypeScript, and full-stack real-time software, with hands-on experience deploying production agentic AI

  • Fast-moving builder with UK work authorization who thrives in high-pressure environments and is eager to take on more responsibility than a traditional role allows

We never post fake jobs
