Senior Frontend Engineer - Walking Motivations Pillar (FR)

Hi there! 👋

🐼 About us

WeWard is the app that rewards you for walking and turns everyday steps into real-life rewards, connections, & positive impact!

Our mission is to help people move more, feel better, and make movement meaningful.

Today, we are trusted by 25M+ users worldwide, with a fast-growing, international team and offices in Paris and New York.

Our ambition is to build the world’s leading movement-and-rewards platform, scaling globally while using technology, data, and smart incentives to drive lasting behavior change and wellbeing at scale.

🎯 About the role

Reporting to the Walking Motivations team, alongside Surya, you'll work as a Senior Mobile Engineer on the pillar that puts the walk back at the heart of WeWard.

WeWard rewards walking — but rewards aren't the whole story. Our Walking Motivations Pillar exists to make walking itself feel good: more habitual, more meaningful, more fun. We build the features people open the app for before they ever think about the reward.

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

The Walking Motivations Pillar works on 3 core ambitions:

• Step uplift — a measurable increase in daily steps. We move the body, not just the metric.

• Lasting motivation — making walking a habit users come back to on their own.

• A wonderful experience — the kind of product moment that turns a user into a multi-year member.

👉 Your impact/responsibilities

As a Senior Mobile Engineer inside the Walking Motivations Pillar, you will:

Ship and own

• Ship mobile features end-to-end on iOS and Android

• Lead new walking experiences — gamification, social hooks, habit-forming mechanics

• Shape our map and location-based experiences — places to go, routes to explore

• Leverage Widgets, Live Activities, Lockscreen and notifications to stay close to users

Drive technical excellence

• Optimise step tracking, battery, and background processing

• Contribute to pillar-level architecture with the CTO and Engineering Manager

• Spot fragile areas, debt, and sensor/permission risks early

• Reduce long-term debt without derailing the roadmap

Collaborate and mentor

• Frame trade-offs with Product and Design

• Guide pillar engineers on complex technical decisions

Our app is built with React Native and TypeScript, with native Android (Kotlin) and iOS (Swift) modules where it matters — step tracking, sensors, system integrations.

Our commitments

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

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

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

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

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

Preferred experience

🧠 What we’re looking for

You’re the perfect match if…

• You have 5+ years of experience as a Mobile Engineer, with strong proficiency in TypeScript and React Native, and hands-on experience shipping production apps at scale

• You have solid expertise in at least one native platform (Android/Kotlin or iOS/Swift), and you're comfortable diving into native modules when React Native isn't enough

• You're able to understand and debug large, complex codebases — and you enjoy it

• You can leverage AI and are eager to grow your skills with it

• You love combining continuous improvement and agility, always bringing new ideas to the table. At WeWard, our spirit is Test & Learn — we trust you to experiment (we deploy to production more than ten times a week!)

• You have a natural interest in the startup world and want to make a tangible impact in your next adventure

• You're motivated by contributing to the health and wellness sector — and you genuinely care about whether someone walks more because of what you built

• You're eager to evolve in an international environment — WeWard is now present in Spain, Italy, the US, Germany, the UK, and more!

Bonus

• Experience with mobile sensors, background tasks, or step/activity tracking

• Familiarity with mobile observability and monitoring tools (Sentry, Datadog, Firebase…)

• Passionate about clean, well-tested, and maintainable code. Takes ownership and pride in code quality.

If this sounds like you, apply — we’d love to meet you. 🎉
