Full Stack Developer, MarTech

At ASSA ABLOY, our mission is to make securely accessing the things in your life noticeably easier, without being noticeable. As a Full Stack Developer
, you will take ownership of our internal design system — a versioned suite of React components, Tailwind configurations, and headless primitives published as NPM packages and used across the organization. You will design clean, reusable, strongly typed component APIs, build high‑quality product interfaces in React, and contribute to our Laravel backend where needed. You’ll collaborate closely with design, product, and backend engineering to deliver interfaces that are accessible, performant, and visually consistent.

A significant portion of this work focuses on CMS‑driven marketing and landing experiences
. You’ll build and integrate design‑system components that empower content authors to assemble pages, and you’ll connect those pages to external digital tools and third‑party services. This is a frontend‑leaning role with meaningful full‑stack scope. While you spend most of your time in React, you will also consume — and occasionally extend — our Laravel APIs. The role is hands‑on and technically influential: you’ll help set architectural direction and mentor other engineers, without direct people‑management responsibilities.

This position will sit on‑site in Berlin, CT reporting to the Director of Marketing.
