Description & Requirements

Who we are looking for

✔ Do you design data models that bring clarity to complex, high-scale systems?
✔ Are you confident defining API contracts and documentation standards that engineers trust?
✔ Can you turn evolving requirements into clean, production-ready XML/JSON/YAML — without losing precision under pressure?

Join us in building the data backbone for the Olympic Games 🏅

Why this role matters:

Define how data is structured, governed, and exchanged across the Olympic ecosystem.
Influence performance, reliability, and scalability of systems used by millions worldwide.

Why This Project Is Exceptional:

🏅 Work on systems supporting the Olympic ecosystem

📱 Build a flagship mobile and web experience for a historic global event

🌎 Collaborate with international teams across Europe and beyond

⚙️ Deliver high-scale, mission-critical systems that must perform under worldwide attention

🚀 Operate at the forefront of digital transformation

🎯 What we expect from you:

Strong understanding of hierarchical data, nested structures, XML/JSON/YAML, and modeling principles.
Experience designing schemas in large, multi‑team environments.
Ability to work with Python or TypeScript to express logic and communicate with engineers.
Practical experience with OpenAPI 3.0 / Swagger and API‑driven ecosystems.
Ability to translate UX, business flows, and requirements into clean data contracts.
Clear, structured communication in English — able to lead conversations with diverse stakeholders.
Ownership mindset: structured, consistent, detail‑oriented, and comfortable with ambiguity.
Calm, analytical approach in high‑pressure, high‑visibility environments.

Nice to have:

Schema validation (XSD / JSON Schema), versioning, backward compatibility.
Experience in event‑tech, media, or sports‑tech ecosystems.
Strong technical writing skills.

Your future role

Own the data. Shape the standards. Drive how systems communicate at scale.

What will be your role:

End‑to‑end ownership of data domains critical to Olympic operations and digital products.
Definition of conceptual and logical data models that guide product strategy and engineering design.
Design of scalable XML/JSON/YAML structures that support multi‑team development and long‑term maintainability.
Creation and governance of REST API contracts (OpenAPI 3.0) that ensure alignment across all teams.
Translation of business flows, UX journeys, and product requirements into precise data interactions.
Assessment of cross‑system impact and clear articulation of risks, dependencies, and trade‑offs.
Driving alignment across stakeholders — backend, frontend, UX, QA, product, and architecture.
Setting and enforcing standards for naming, versioning, documentation, and data quality.
Challenging and reviewing models and APIs to ensure consistency, scalability, and clarity.
Leading conversations on edge cases, governance, and architectural direction in a complex environment.
