We’re doing things a little differently…. Want to join us on our journey, to help us grow?

We’re now looking for a Senior Front End Engineer to join our Members team with the skills and experience to prioritise and manage change to reduce engineering Run rate by de-risking areas of code with the mobile application, web dashboard and supporting member API services.

Our Engineers come from varied backgrounds, from landscape gardening to photography. While some have a degree, others have come from academy courses such as Makers and General Assembly. However, what we all hold in common is a passion for technology and building an awesome product for our members.


Senior Front End Engineer (React.js, React Native)

As our platform grows rapidly to support new and existing members, we want to continue to delight them whilst automating and scaling even more aspects of our daily work. We’re looking for a Senior Front End Engineer to help us on our journey. 

We are cloud native and value building platforms and systems that are resilient, cost effective and automated with great observability. As a regulated financial company that is ISO27001 certified and values innovation and continuous delivery we have an ongoing challenge to meet continued, rigorous data, security and auditability requirements.

Our technology stack is primarily Node.js running in containers and serverless Lambda, deployed to AWS using Infrastructure as Code. We build for scale, incorporating design patterns such as messaging using SQS, circuit breaker and bulkhead patterns, and our teams deploy their own code to many AWS services (including Lambda, EventBridge, ECS and RDS) multiple times per day, with zero downtime, following Continuous Delivery principles and practices.

At By Miles we are organised into cross-functional business aligned teams that include engineers, product and design - teams build and run their own systems in production environments and regularly report they have a high-level of psychological safety.
