You’ll own the full-stack system—from ingestion of messy signals to deterministic state machines—ensuring reliable, high-stakes infrastructure for global aviation hubs.
Senior Backend/Fullstack Engineer at Joinkyber
Commercial aviation loses $15B annually to ground delays, and Joinkyber.com is fixing it by building the AI orchestration layer that replaces manual spreadsheets with real-time systems. As a Senior Backend/Fullstack Engineer at this EF Fall 2025 startup, you will own the mission-critical decision engine driving live airport operations while working directly with founders from F1 and space-tech backgrounds. With pilot programs already reducing labor waste by 60% and a compensation package where budget is not a limiting factor, this is a rare chance to build high-consequence technology that keeps the world moving.

Role overview
Kyber is the intelligent decision-making assistant that transforms airport ground operations from reactive dispatching to data-led, predictive execution.
What you will do
- Design real-time data processing pipelines that reconcile messy operational signals into a single, canonical truth for airport ground handlers and airlines.
- Build conflict detection systems and state machines that manage complex dependencies across staff, equipment, and gate assignments under tight latency constraints.
- Own the infrastructure-as-code and DevOps layer, ensuring 100% reliability for production systems where downtime directly translates to missed flights.
Who this is a fit for
- Has 3+ years of experience building production-grade backend systems at high-growth startups, specifically demonstrating deep proficiency with TypeScript and Python.
- Demonstrates expertise in event-driven architectures, scheduling algorithms, or workflow engines with a focus on deterministic compute and system correctness.
- Possesses a strong builder mentality and DevOps background in IaC, CI/CD, and observability for mission-critical, cloud-native environments.
Why this role is remarkable
- Build the decision engine behind live airport operations, transitioning from standard CRUD apps to high-consequence systems that prevent worldwide flight delays.
- Join a pre-seed team led by an ex-F1/Lufthansa operations expert and a space-tech CTO with pilot programs already demonstrated to reduce labor waste by 60%.
- Experience massive technical ownership with a top-tier compensation package and the systems complexity typically found at much later-stage companies.
