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 partner closely with product, engineering, design and UX to provide the foundations that power Kraken Customer.
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 technologyOn 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).
What you’ll do:
- Access control management - how our clients decide which users have permission to do what.
- 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!
- 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.
What we’re looking for:
- This is a mid-level engineering role, 3+ years of experience is ideal.
- Django / python experience
- Equivalent server side framework / language experience also fine!
- React JS experience
- Equivalent framework experience is also fine!
- Experience working with SQL databases
- PostgreSQL preferred
- Curiosity, this is a role where you’ll have the opportunity to work on a wide variety of tech / products across the entire stack.
- Takes the initiative, self-organised with an attention to detail
- We are a remote-first team and don’t micro manage, for this to succeed we require our engineers own their work and act as their own driver.
- Excellent English communication skills, both written and verbal
