Full job description

We're Hiring!

We’re hiring a Founding Frontend Engineer. You will be our first in-house Frontend Engineer, responsible for developing, maintaining, and scaling our user portal - the first thing customer’s see when engaging with our product. You’ll also be crafting the principles and values we uphold when we do frontend engineering now, and into the future. This is an opportunity to take complete ownership over our frontend stack, work with an incredible team of talented engineers, and to help build the future of immunity on the internet.

Your Responsibilities

Owning the full frontend surface from design system foundations to performance to deployment.

Translating UI/UX designs into clean, efficient, and maintainable code.

Developing accessible and high-performing user interfaces across devices.

Optimising application performance and ensuring cross-browser compatibility.

Identifying, troubleshooting, and resolving front-end issues efficiently.

Decision making on authentication strategies and secure session/token approaches (e.g. JWT/JWE, token rotation).

Collaboration with designers, developers, and stakeholders to deliver seamless digital experiences.

Enforcing and maintaining best practices in frontend development, including code quality, testing, and performance optimisation.

Requirements

You Should Have

Strong commercial experience as a front end developer, delivering production Web applications

Excellent JavaScript and TypeScript skills, with strong experience building UI with React

Solid HTML5 and CSS skills, including building responsive interfaces that work well across devices and browsers

Experience working with modern Web application patterns, including server-side rendering (or similar techniques) and performance-minded UI delivery

Experience building enterprise scalable applications against REST API’s

Familiarity with common architectural patterns and building maintainable component-based applications

It Would Be Nice If You Have

Worked in a early-stage startup before and know what it feels like when there's no playbook.

Used AI coding tools and know how to get leverage from them without losing control of the codebase.

Built something data-heavy (dashboards, tables, real-time updates) and know where the performance traps are.

Benefits

£75,000 - £90,000 Base Salary
Employee Matched Pension Plan
Stock Option Package
Wellness Budget
Monthly Socials
