Senior Frontend Engineer

Plentific is a property technology platform used by housing providers, local authorities, housing associations, asset managers, and contractors across the UK and Germany to coordinate repairs, maintenance, and contractor workflows  platform combines a marketplace, workflow automation, and operational analytics, and is built to handle the volume and compliance demands of social housing, local authority property portfolios, and large-scale residential operations.

We are headquartered in London and our team works across Europe.

We are growing the team to expand the platform's coverage across Europe and to integrate AI throughout the product and operating model. If you are interested in working on hard, real-world problems in a sector that has long been under-served by good software, we would like to hear from you.

We are hiring a Senior Frontend Engineer to build the product surfaces that housing providers, contractors, and residents use every day. This is a fully remote position; we currently have remote engineers based in the UK, Germany, Turkey, Poland, Italy, Spain, and Portugal. You will report to a Team Lead, a hands-on engineer who still writes code and has a small number of engineers reporting to them, and work alongside product managers, designers, backend engineers, and data analysts.

Our frontend is built on Type Script, React, React Router, Tan Stack Query, MaterialUI and BaseUI, against an increasingly service-oriented backend built in Django REST Framework and PostgreSQL. The codebase is large but clean, because we put real weight on design patterns, readability, testability, maintainability, and extendability.

The engineering team sits at the centre of what Plentific does, and the problems are genuinely difficult: online payments, quoting, invoicing, booking, search and scoring algorithms, in-app messaging, real-time notifications, and fraud prevention. Much of it is high-volume and messy legacy integrations, complex permissions, strict compliance requirements, and users who need software to fit how work actually happens on the ground.

We expect you to apply engineering judgement to these problems rather than only writing the code in front of you, and to treat agentic, spec-driven development as a normal part of how you work rather than an experiment.

Success in this role means shipping interfaces that are fast, accessible, and well-tested, raising the standard of the frontend codebase around you, and leaving the engineers you work with better than you found them.

• Build and maintain product interfaces in Type Script, React, Tan Stack 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.
• Review, refactor, and retire existing code so it meets the requirements of improved or new features.

• 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.
• Instrument frontend observability with tools such as Sentry, Grafana Logs or New Relic, and act on what they show.
• Debug and fix production issues across our applications, including the integration points where frontend and backend behaviour diverge.
• Design against common frontend…
