Our team Frontend Platform is a multi-disciplinary product group that builds shared frontend systems, tools, and standards so teams across Kraken can ship consistent, accessible, enterprise-grade experiences faster and with less duplication.

We also own key cross-cutting capabilities like frontend architecture/developer experience, design tokens and UI patterns, instrumentation standards, and access/permissions patterns. In order to facilitate this remit we require engineers who are capable of working across the frontend and backend.

Our technology On the server-side we primarily use Python and Django, with a combination of Django Rest Framework and GraphQL APIs. We leverage AWS heavily, and manage our resources via the Hashistack (eg Packer, Consul, Terraform) as part of a continuous deployment pipeline. Every push to main is a deployment to production, so we ship hundreds of times per day! On the front end our primary customer application uses server rendered templates via Django sprinkled with HTMX and vanilla JS to power interactive features. We have many single page applications spread throughout powered by React JS where there are user experience requirements that demand it (e.g our Live Chat system, Phone system).

• Internationalisation - Kraken is now used across the globe, we need to ensure it’s available in everyone’s native language!
• Accessibility - how can we make Kraken software usable for everyone, no matter what their needs are!

With exciting projects in our future:

• Embedded Apps - How our clients embed their own applications within Kraken.
• Design System - working with our excellent design team to expand our existing component library into a holistic design system and how that translates to UX patterns within the app.
• Frontend Platform - creating a set of reusable tools to enable software engineers across Kraken, to own the whole lifecycle of an application’s development.
