## Job description

We're putting together a talented team to build the #1 training platform for Runners We help everyday runners become outstanding by building an incredible app providing world-class training, coaching and community for everyone, whether you're improving your 5k time or training for your first marathon. We’re growing extremely fast! In November 2023 we closed a $6.5M funding round led by JamJar with participation from Eka Ventures, Venrex and Creator Ventures. In 2024, we were selected by Apple as one of three global finalists for the iPhone app of the year, reflecting the innovation and impact of what we’ve built & in 2025 we were acquired by [Strava](https://www.strava.com/about?hl=en-GB)! Our ambition is huge: to become the go-to global leading training platform for millions of runners everywhere. We’re growing with purpose and looking for people who want to build something meaningful with lasting impact. With the recent acquisition by Strava accelerating our journey, now is a really magical time to join. 🚀 The Team You'll Join Our Growth Engineering team owns key parts of the user journey into Runna, working across web and app to turn first time visitors into long term, engaged subscribers. You'll collaborate closely with product, design and data partners, as well as our GTM and business development teams, to shape how new users first discover and experience Runna.

We follow a flexible hybrid model that translates to more than half of your time on-site - 3 days per week in Runna's office based in London, UK.

## What You'll Be Doing

- Architect, build, test and ship high impact user journeys and subscription funnels, focusing on turning curious visitors into engaged subscribers.
- Design and run experiments across web and app - onboarding flows, paywalls, plan discovery - to improve conversion at every step.
- Work closely with Product, Design and Data to help prioritise opportunities, define success metrics and make decisions grounded in experiment results.
- Collaborate across teams to ensure users have a smooth, consistent experience as they move between products and platforms.
- Implement and maintain instrumentation, tracking and tooling so we can understand behaviour, spot issues quickly and measure impact.
- Own features end-to-end: from early discovery and technical design through to implementation, rollout, monitoring and iteration.
- Contribute to our developer experience by improving CI/CD, testing and release workflows so the team can ship and learn quickly.

## What You'll Bring to the Team

We're looking for people who are strong in some of these areas, not necessarily all of them. If this role excites you, please apply.

- Solid TypeScript / JavaScript experience.
- Experience building user-facing product surfaces where conversion and UX really matter — onboarding, paywalls, landing pages, growth loops, etc.
- React experience (React Native is a bonus, not a requirement).
- 2+ years of full stack experience — we value full stack experience more than depth in just one layer.
- Comfortable working in a fast paced, iterative environment with lots of experimentation and learning from data.
- Able to deliver features end-to-end: from architecture through to rollout, measurement and iteration.
- Curious about what didn't work as much as what did.

## How We Work

We believe great engineering is a team sport. Here's what that looks like in practice:

- Iterative development, continuous deployment and test automation.
- Knowledge sharing and collaborative design — we build together, not in silos.
- Shared ownership of code and outcomes across cross-functional teams.
- Psychological safety to experiment, fail, learn and try again.

Bonus Points These are optional extras, not hidden requirements:

- Experience with Swift or Kotlin for mobile.
- Experience working on growth, experimentation, or funnel optimisation teams.
- Experience with analytics and experimentation tooling (A/B tests, feature flags, etc).

Our Tech Stack Here's what we work with. You won't need all of it on day one. Frontend

- React or React Native (iOS and Android)
- TypeScript
- GraphQL (Apollo Client)

Backend

- Node.js
- Serverless (AWS) — Lambdas, SQS, DynamoDB, EventBridge, S3

Tools & Platforms
