Senior Frontend Developer - Vue3, TypeScript, Javascript ES6+ 

Flexible hybrid working - 1 day per week in London

£75-85k DoE

This small, incredibly successful healthcare scale-up is seeking an experienced Senior Frontend Developer to deliver a dashboard web app. This is a SPA (Vue) that reconfigures upon login to deliver different experiences depending on the user persona (patient, clinician, executive, etc.). APIs are to the backend app, the data warehouse and proprietary clinical CMS. They use Cypress for end-to-end testing and also for Vue component testing.

The JS + TS codebase is a mixture of polymorphic classes and functional services. There is a lot of local modelling - most backend responses are deserialised into models. You will need to be experienced with these approaches and have good knowledge of software architecture design patterns. Business logic is tested using mocha - currently they have just under 1,000 such tests. You will need to have experience working with complex unit tests and fixtures.

Requirements:

• Successful academic background and/or strong frontend portfolio
• At least 5 years' experience in frontend development, including complex web apps
• Proficiency in JavaScript (ES6+), Vue 3 and TypeScript
• Strong understanding of design patterns, architectural best practices, OOP and data structures
• Comfortable contributing to architectural discussions and tech decisions
• Strong understanding of frontend test automation, creating tests as part of the definition-of-done
• Experience refactoring and modernising large-scale web applications, including upgrading frameworks, optimising performance, and managing technical debt
• Ability to deliver clean, accessible and responsive UI
• Ability to thrive in a fast-paced SCRUM environment
• Strong problem-solving and debugging skills with an attention to detail

Desirables:

• Experience designing, building and maintaining software development kits (SDKs)
• Familiar with microservices architecture
• Working experience with TailwindCSS, Vuetify or any other frontend design libraries

The Senior Front End Developer's remit will include delivering high quality, testable code, implementing automated testing wherever practical, working with QA testers to ensure code is appropriately tested, and performing your own manual testing, where required, championing best practices for architecture, development and testing etc.

The company’s mobile, web and data products are live in 12 countries and 8 languages, spanning 3 AWS regions. Their business is growing very strongly.
