Senior Frontend Engineer

About the role

Plentific is seeking a Senior Frontend Engineer to build and maintain product interfaces for their property technology platform. You will work within a cross-functional team to deliver high-quality, accessible, and performant web applications while integrating AI into the product development lifecycle. This role involves applying engineering judgement to complex, real-world problems in the housing sector.

Responsibilities

• Build and maintain product interfaces in TypeScript, React, TanStack Query, React Router, MaterialUI and BaseUI across our web applications.
• Translate product requirements and design concepts into technical documents that set out scope, system behaviour, edge cases, and high-level technical analysis.
• Design component APIs, state management, and data-fetching patterns that stay readable and extendable as the codebase grows.
• Integrate against REST APIs in a service-oriented architecture, shaping the contracts with backend engineers rather than accepting whatever is offered.
• Diagnose and resolve page load, rendering, and other frontend performance problems.
• Write unit, integration, and end-to-end tests that give the team confidence to ship frequently.
• Turn ambiguous product ideas into implementation-ready specs, including user flows, component behaviour, edge cases, acceptance criteria, and test expectations.
• Evaluate AI-generated code critically for correctness, maintainability, security, performance, accessibility, and fit with Plentific's architecture.
