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 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
