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.
• EU residency.

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.
