The Opportunity:

Join Attest at a pivotal moment as we transform how the world’s leading brands discover and act on consumer insights through Compass, our AI-native conversational interface revolutionizing market research. Attest powers insights for brands like Netflix, Unilever, Nestle, and Reddit, connecting them to 150+ million consumers across 59 countries. As a Senior Frontend Engineer on the Compass squad, you’ll be at the forefront of building intuitive, AI-powered interfaces that help customers uncover insights rapidly through natural conversation.

You’ll work on complex challenges at the intersection of frontend engineering, conversational UX, and data visualisation, shaping how leading brands make faster and more confident decisions. This role involves shaping technical direction within your squad, contributing scalable frontend patterns, and mentoring engineers while collaborating with Product, Design, Backend Engineering, and Data Science. Our frontend stack includes VueJS, Type Script, and OpenAPI, and we are continually evolving how we build and deliver software.

We’re looking for an engineer with strong product instincts who enjoys collaborative problem-solving and prioritizes meaningful impact over perfection. If you’re motivated by building thoughtful user experiences and improving systems over time, we’d love to hear from you.

We are able to offer between £85-95K depending on experience, with equity options and comprehensive benefits.

We work in a flexible hybrid model. Most squads collaborate in person around two days per week, with flexibility around which days work best. This helps us balance meaningful face-to-face collaboration with time for focused engineering work.
