Our front-end applications are written in React with TypeScript using Gatsby and Next.js. For our REST and GraphQL APIs we use TypeScript and NodeJS, with PostgreSQL and ElasticSearch behind the scenes.

All of our services are hosted on AWS using Elastic Kubernetes Service. CI/CD is handled by Jenkins, with automated Docker builds and deployments to staging. We use Github and JIRA to help us keep on top of our tasks, manage and host our code.

We have a strong culture for testing. We are individually responsible for our work and are immensely proud of the quality we produce. We try and automate as much of the testing as possible.

We have a learning and development budget for keeping up to date which can be spent on conferences, courses, and even books. We encourage sharing what we learn with the rest of the team and the wider community.

We are truly cross-functional: as well as designers and product managers, our teams include data analysts, mortgage advisers and marketing specialists. We’re focused on results: meetings are banned two days a week, and if you need to work from home to finish a project or leave early to manage your energy we encourage you to take it.

About the Role

• Develop scalable web applications for award-winning consumer-facing financial tools
• Develop quick internal admin tools for analysts to create and maintain critical rule sets around consumer financial data
• Integrate new external APIs from vendors or other teams into platform
• Work with UX and design team to transform wireframes into living products
• Build new REST and/or GraphQL endpoints for representing our data to consumer applications
• Own full development requirements and implementation, release management, QA regression scripts, and deployment to containerized production environments
• Communicate results and impact to business stakeholders

About You

• Experience with Node.js and a UI framework (React a plus)
• Experience with unit, integration and end to end testing tools and practices
• Experience with documenting, creating, and consuming REST APIs (GraphQL a plus)
• Keen eye for detail when translating design and requirements into working code
• Proficiency with security requirements, authentication and authorization layers (OAuth2, Google Sign-in)
• Aware of front-end performance implications and best practices
• Familiarity working in the cloud, especially as it pertains to the front end: (Amazon S3 or Azure Blob, Cloudfront, Cloudflare, Fastly, etc.)
• Familiarity with tag and event tracking libraries (e.g. Segment, Google Analytics)
• Fluent at using Git
• Excellent communication, collaboration and writing skills
• You feel comfortable that our values - being brave, investing in each other, making it simple, and owning it - reflect aspects of your personality and approach to work.
