About the project

How we hire:
At Pentalog, excellence is what you'll do. We're guided by a mission to positively impact the software development world.

Pentalog has partnered with a global market research company and is looking for a Typescript Developer with experience in building, deploying and maintaining mobile-focused React web applications. This role offers the opportunity to lead a small team in the development of a greenfield Progressive Web Application (PWA). You will have the opportunity to make key decisions on client-side development and be responsible for setting up the project for testing, CI and deployment.

You'll be provided with full Figma UI designs and a pre-existing backend API to produce a responsive, mobile-first application that renders fully on the client and provides a similar experience to a sister native Android app they've developed.

The PWA requires the latest supported features in Chrome and Safari, such as Push messaging and background synchronisation. Experience of developing ServiceWorker with Webpack/Vite using libraries such as Workbox is highly desirable. Performance of the PWA is important, so knowledge of using tools such as Lighthouse / Core Web Vitals, JS bundling and React-compatible alternative renderers such as Preact would be highly valued.
