Staff Engineer, FE – Account Experience

This is a fully remote position, open to applicants in United Kingdom.

📋 Description

• Establishing and leading the front-end technical strategy for the Account Experience teams, encompassing architecture and component-system decisions, as well as hands-on implementation where it matters most.

• Taking ownership of the architecture for a complex, data-intensive merchant platform — including the patterns, state management, and performance characteristics that remain robust as the surface area expands.

• Influencing the evolution of Primer AI Companion into a premier merchant interface, focusing on the front-end architecture that ensures a conversational surface feels integrated within the platform.

• Maintaining a coherent user experience across Account Setup, Monitors, Workflows, and Auditing — constructing the shared component and design-system foundations that prevent these areas from diverging.

• Guiding engineers across teams without direct authority through code and design reviews, as well as providing technical mentorship that elevates the front-end standards around you.

• Taking responsibility for aspects often overlooked: prioritizing accessibility, performance budgets, and front-end observability as primary concerns rather than afterthoughts.

• Collaborating with Product and Design, along with backend engineers across teams, to influence decisions where front-end limitations or opportunities are significant.

⛳️ Requirements

• Proven experience operating at the staff or principal level: directing front-end technical strategy across multiple teams, not limited to a single team.

• Extensive front-end engineering expertise with TypeScript and React, along with a history of architecting complex, long-lasting web applications.

• Genuine proficiency in the factors that differentiate good front-end from exceptional: state management at scale, performance, accessibility, and component-system design.

• The type of judgment that quickly earns trust — engineers follow your technical guidance because of your expertise, not merely due to your title.

• Sufficient comfort across the technology stack to understand the APIs and services your front-end relies on, and to collaborate with backend engineers as equals.

• Excellent written and verbal communication skills, including the ability to make complex technical decisions understandable to Product, Design, and non-technical stakeholders.

• Experience in payments, fintech, or platform environments is desirable, although depth of engineering experience is prioritized over industry specifics.
