About 1st Formations

At 1st Formations, we empower entrepreneurs to start, run, and grow their businesses with confidence.

Running a business shouldn’t be slowed down by company formation, statutory compliance, accounting, or payroll. From day one, these essentials should be seamless, reliable, and intelligently handled — freeing founders to focus on building and scaling.

We’re a leading UK provider of company formation and compliance services, building a modern, fully integrated technology platform that supports founders at every stage of their journey. Our platform brings together formation, compliance, accounting, payroll, and ongoing business support in one cohesive experience.

No stitched-together services.
No legacy workflows disguised as software.

Just a single, scalable platform built for ambitious founders who want to move fast, stay compliant, and grow with confidence.

Why Join Us Now?

You’ll be joining a business with strong momentum, clear direction, and real opportunity for progression.

£18m annual revenue, including £9m ARR
Over 1 million companies formed
Certified B Corp and Carbon Neutral Business
Forecast to grow 5x–10x over the next three years

The Role

We're seeking a Senior Frontend Engineer who combines technical excellence with a sharp eye for detail and a passion for delivering beautiful, pixel-perfect user interfaces. In this role, you'll play a critical part in shaping the user experience of our product by transforming high-fidelity designs into seamless, responsive, and accessible web applications using React and Next.js.

You'll work closely with our product and design teams to shape the architecture of our frontend systems at the UK's leading company formation agent — 1 million+ companies formed since 2014.

Key Responsibilities

Develop, maintain, and optimise high-quality, responsive, and performant web applications using React and Next.js, ensuring a consistent experience across devices and browsers

Collaborate closely with product designers to translate Figma mock-ups into seamless, visually polished interfaces that meet both aesthetic and functional requirements
Write clean, maintainable, and efficient code adhering to modern development standards, accessibility guidelines, and industry best practices
Contribute to frontend architecture — defining scalable patterns, reusable components, and maintainable structures to support long-term product growth
Participate in code reviews and technical discussions, sharing knowledge and upholding code quality and consistency across the engineering team
Continuously improve application performance through profiling, optimisation, and modern tooling and techniques
Stay current with the latest trends and advancements in frontend development, particularly within the React / Next.js ecosystem

What we are looking for

10+ years building modern web applications, with deep production expertise in React and Next.js
Expert-level JavaScript and TypeScript, plus strong HTML and CSS — including responsive layouts, accessibility, and cross-browser compatibility
In-depth experience with Payload CMS
Proven ability to translate Figma designs into pixel-perfect, maintainable frontend code
Experience with analytics, A/B testing, and data-driven methods to understand user behaviour and inform feature development
Solid understanding of frontend performance — able to identify bottlenecks and implement effective solutions
Proactive, self-driven, and highly accountable — you take initiative, follow through, and hold yourself to a high standard
Grit and drive — comfortable diving into complex problems, experimenting, and iterating to find the best solution
Collaborative team player who thrives in a fast-paced, high-growth environment

What We Offer

£90- £110k and comprehensive benefits package
Hybrid working model
Real opportunities for progression as the business scales
The chance to influence both customer experience and product development
A culture that values ownership, impact, and continuous learning
