Job Title: Junior Software Developer

Company Description: Joinkyber.com – 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 2–3 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

This isn't a trick. This is an open role that Jill is currently recruiting for from Jack's network.
Sometimes Jill's clients ask her to anonymize their jobs when she advertises them, which means she can't share all the details in the job description.
We appreciate this can make them look a bit suspect, but there isn't much we can do about it.

Give Jack a spin! You could land this role. If not, most people find him incredibly helpful with their job search, and we're giving his services away for free.
