About You

You’re not looking for another job — you’re looking for a mission. You take ownership, move fast, and think beyond your IDE. You want to see your work shaping real products — used by athletes, coaches, and organizations at the highest level. You’re a top‑tier developer who thrives on solving complex problems and turning ideas into impact. You want to build something meaningful — not just ship features. You’ll be joining a highly experienced, international team that’s building advanced technology for some of the most exciting names in sports and performance. You’ll have a real voice in architecture, product, and direction — and your code will be part of something global from day one. You thrive in an environment where iteration beats bureaucracy, and bold ideas matter more than titles. You’re deeply curious about how AI is transforming software development — not just what it can generate, but how it can elevate human creativity, accelerate iteration, and push boundaries. You actively use AI‑assisted development tools (Copilot, Claude, Crush, Codex, etc.) and see them not as shortcuts, but as extensions of your skill — the future of engineering. If you’re the kind of developer who wants to build ambitious, world‑class products — not just work on them — you’ll fit right in.

About Athlera

Athlera is a sports technology company building the next‑generation platform for movement, performance, and learning.

We’re now scaling internationally, with our core team based in Gran Canaria and collaborations across Europe. Joining Athlera means becoming part of a company that combines deep technology, design, and human understanding — shaping how the world experiences movement.

What You’ll Do

Build and maintain AI‑powered platforms for sports and health analytics.

Work across the stack — from API and data pipelines to front‑end experiences.

Develop with JavaScript, TypeScript, Next.js, React, and Python, writing clean, maintainable, scalable code.

Use Docker, CI / CD pipelines, and modern DevOps practices to deploy efficiently.

Collaborate closely with designers, AI researchers, and product leads.

Use and experiment with AI‑assisted coding tools daily — Codex, Copilot, Claude, Crush, and others.

Contribute ideas far beyond your job title — product architecture, scalability, and innovation.

What We’re Looking For

• Strong experience with JavaScript / TypeScript and frameworks like Next.js or React.
• Solid proficiency in Python and familiarity with modern backend design patterns.
• Experience with Docker, containerized deployments, and CI / CD automation.
• A proactive builder — curious, independent, and accountable.
• Comfort working with AI‑based development tools — not as a novelty, but as an integral part of your workflow.
• You value structure but thrive in experimentation. You’ll be part of an international, multidisciplinary team, so fluency in English is essential for collaboration and communication.

Nice to Have

• Experience integrating AI models or APIs (OpenAI, Anthropic, Hugging Face, etc.).
• Familiarity with data pipelines, event streaming, or edge computing.
• Background in sports, health, or performance‑related tech products.
• You see engineering as creative problem‑solving, not just execution.

Why You’ll Love It Here

You’ll have creative and technical freedom — we trust you to own your code and ideas.

You’ll work closely with seasoned founders and experienced professionals who’ve built and scaled successful ventures before.

You’ll be part of a team that codes almost entirely with AI tools — the workflow of the future.

You’ll help define how intelligent systems reshape human performance and understanding.
