Our company

Every ride on a Beryl bike e-bike or e-scooter is a journey that didnt happen in a 2025 that added up to more than 3.5 million journeys.

The software youd work on is what makes that possible: it shows a rider the nearest available vehicle and unlocks it in seconds streams location and telemetry back from thousands of vehicles in real time tells our street teams which ones need attention next and keeps it all running 24/7.

Were the UKs only B-Corp micromobility operator and were growing nationally. Its a great time to join us.

About the role

Youd join our Software team. Supporting a react-native multi platform customer mobile app an react-native android app used by our operations teams an automated tasking engine python backend microservices deployed on Kubernetes in our GCP infrastructure..

Were a small team so the work is varied and youll touch most of the your first six months wed expect you to:

• Own problems end to end from an ambiguous riders are reporting X through to a fix in production
• Shape architecture not just implement it: youll be in the room when we decide how a new system should work and we want you pushing back when were wrong
• Get to know a significant area of the platform well and become someone the team turns to when decisions come up there
• Raise the bar around you through code review pairing and sharing knowledge
  
  

Were not looking for someone strong in everything. Were looking for genuine depth in one area; mobile backend or frontend plus enough range to work confidently across the others. If youre a Python engineer whos comfortable in React or a React Native developer who can hold their own on a backend service please apply.

Were evolving how to fit AI into our workflow responsibly whilst continuing to focus on quality and a good understanding of our codebase.

Our technology stack consists of:

• React Native mobile applications
• React web applications
• GraphQL layer using Apollo Server and Apollo Client

• CI/CD via CircleCI and Helmfile (server) and Bitrise (mobile)
• Error reporting using DataDog and Sentry
• Claude code
  
  

What were looking for

Depth in at least one of these:

• Backend - Python in production including running and supporting live services
• Frontend - TypeScript and modern JavaScript with real React experience beyond the basics: context async state composition patterns
• Mobile - React Native and shipping to the app stores

And whichever your area were looking for:

• Enough range to work confidently outside it. You dont need to be expert everywhere but you should be comfortable reading and contributing across the stack
• Comfort with relational databases and designing schemas that hold up
• Pride in readable well-tested software and the ability to explain why a design is the right one
• The judgement that comes with seniority: knowing what to build what to leave alone and when to say so

Great if you have it fine if you dont:

• Any of the three areas above that isnt your main one
• Docker and containerised applications
• Building and consuming REST and GraphQL APIs
• Kubernetes Terraform or GCP
• Experience working with AI coding agents
• IoT and distributed connected hardware in the real world

We know the ideal candidate rarely exists. If youre missing a couple of these but the role sounds like you apply anyway and tell us how youd close the gap.
