About the role

You’ll join the WeCard team, one of the most creative and ambitious teams at WeWard.

Our mission is to turn walking and exploration into a collectible card game, where every location, discovery, and adventure turn into collectibles that can be earned, traded, and shared.

As a Backend Engineer, you’ll help design and scale the systems powering WeCard — from geolocalisation logic to reward algorithms, from collection tracking to ranking mechanics. You’ll contribute to the architecture, APIs, and data models that make this new layer of the WeWard universe come to life.

You’ll face the challenge of operating a large-scale international platform handling billions of interactions and strong peaks of activity every day.

Excellence is key: in a consumer app used worldwide, every percentage point of performance, stability, or quality directly translates into user growth—or loss.

Responsibilities

• Design, develop, test, and deploy reliable and maintainable code (APIs or scripts).

• Optimize and improve the performance of SQL queries and Python code.

• Take initiative and be capable of leading projects from start to finish.

We’re looking for someone with a strong command of Python, ideally with experience in Flask (though we’re also open to other Python web frameworks such as Django or FastAPI).

You should be comfortable building and consuming APIs, care deeply about code quality, and know that Automation and CI/CD aren’t characters from Hogwarts 🧙— but key parts of a solid deployment process.

Beyond pure development, we expect you to challenge the infrastructure, propose meaningful improvements, and collaborate effectively with DevOps, Product, and Marketing teams 🤝

Our commitments

• You’ll join a team of passionate people who share values of ambition and determination - SUCCEED 🏆

• We give you real autonomy, trusting you to reach your goals in your own way -TRUST 🤝

• You’ll grow in a culture that’s constantly evolving and curious about what’s next -EXPLORE ⛏️

• We’ll support you through challenges, learn from mistakes, and move forward together - PROGRESS 📈

• And every day, you’ll be part of a fun and positive environment where humor is always welcome - SMILE 😁
