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 🏅

In this role, you will own key data domains within a global Olympic technology program — shaping architecture, defining robust models, and designing APIs that power products used on the world’s biggest sporting stage.

If you believe that great systems start with great data — and you take pride in structure, clarity, and craftsmanship — this is your moment 🚀


This is more than a leadership role.
This is your opportunity to shape the digital experience of a global audience.


🌍 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:

Shape how data flows across large-scale systems. Work at the intersection of data, APIs, and product.

🔹 Data & Modeling:

  • Strong data literacy: hierarchical data, XML (1.0), JSON, YAML (1.2) — including nested structures
  • Experience designing and reviewing complex schemas in large, multi-team environments
  • Solid understanding of data architecture (conceptual vs. logical models, ERDs, LDMs)

🔹 Tools & Data Wrangling:

  • Confident with VS Code/Cursor (+ formatting & validation workflows)
  • Comfortable using Excel or Python for data analysis, transformations, and inspection

🔹 Programming & APIs:

  • Working knowledge of Python or TypeScript (ideally both)
  • Able to express logic clearly (incl. Python-like pseudocode)
  • Hands-on experience with APIs (OpenAPI 3.0, Swagger or similar)
  • Translate UX/mockups (Figma, draw.io) into clean JSON contracts & API payloads

🔹 Collaboration & Communication:

  • Excellent English (written & spoken) — clear, structured communication
  • Proven collaboration with engineers, designers, QA & SMEs in distributed teams
  • Comfortable driving discussions on data requirements, trade-offs & edge cases

🔹 Mindset:

  • Detail-oriented, consistent, and solution-driven
  • Proactive, curious, and eager to grow in data & engineering
  • Calm and adaptable in fast-changing environments

➕ Nice to Have:

  • Writing technical docs developers actually use
  • Schema validation (XSD / JSON Schema), versioning & backward compatibility
  • Experience in event, media, or sports-tech ecosystems
Your future role

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

🔹 Data Ownership & Architecture

  • Own and evolve data models & contracts across key business domains
  • Rapidly analyze technical documentation (PDF/Excel) and assess cross-system impact
  • Define and enforce standards: XML/JSON/YAML structures, naming, versioning & documentation quality
  • Drive conceptual & logical data modeling with architecture stakeholders

🔹 Design & Documentation

  • Explore and validate XML/JSON/YAML using advanced tooling (VS Code/Cursor)
  • Design clean, scalable, and reusable data structures
  • Document data flows with diagrams, mappings & concise pseudo-code (XPath / Python-style)
  • Define and maintain REST APIs in OpenAPI 3.0, ensuring spec-to-implementation consistency

🔹 Technical Leadership & Delivery

  • Support backend flows (TypeScript) and build reusable Python data snippets
  • Review and challenge data models, APIs, and documentation across the team
  • Partner with Backend, Frontend, UX/UI, QA & Product to translate requirements into robust data contracts
  • Own Confluence documentation (clear specs, versioning, links to assets)
  • Keep Jira, documentation & delivery aligned — driving transparency and execution discipline

🔹 Mentoring & Ways of Working

  • Act as the go-to expert for data structures, APIs & documentation
  • Mentor Data Specialists on modeling, API design & technical writing best practices
  • Promote a culture of clarity, speed, and engineering craftsmanship
