Job description

Staff Frontend Engineer | London | AI-Native SaaS | £150,000 + Equity

We’re partnering with a high-growth, venture-backed AI SaaS company in London as they scale their engineering team. We are currently on the lookout for a Staff Front End hire to join their team.

Their platform transforms complex, manual workflows into AI-powered systems used by global enterprise clients. Following rapid growth and a major funding round, they’re now looking for a Staff Frontend Engineer to take ownership of their frontend architecture and help define the next phase of product evolution.

With new AI-driven features launching and the product entering a critical scaling phase, this is a rare opportunity to shape the frontend of an AI-native enterprise platform from an architectural level.

What You’ll Do:

• Own and evolve the frontend architecture of a complex, data-heavy SaaS platform, designing scalable patterns that support long-term product growth.
• Lead framework-agnostic frontend development (React, Vue or similar), making sound architectural decisions around state management, rendering strategies, and performance optimisation.
• Design and build AI-native interfaces, integrating LLM-powered workflows such as streaming responses, prompt orchestration, and intelligent automation features.
• Partner closely with backend and ML engineers to productionise AI functionality securely and reliably within enterprise-grade environments.
• Establish best practices across testing, observability, CI/CD, and frontend performance to ensure high reliability and maintainability.
• Contribute to or establish a scalable design system and component architecture.
• Leverage AI-assisted development tools to accelerate delivery, improve code quality, and modernise engineering workflows.
• Mentor engineers and raise the technical bar across frontend development, influencing standards and long-term technical direction.

What We’re Looking For:

• 7+ years of experience building and scaling modern web applications
• Deep expertise in at least one modern frontend framework (React, Vue, or similar) with strong architectural ownership experience
• Proven experience leading frontend systems at scale rather than just delivering features
• Strong understanding of performance optimisation, rendering trade-offs, and complex state management
• Experience building data-heavy, enterprise-grade interfaces
• Hands-on experience integrating or building with LLMs and AI-powered workflows
• Experience using AI-assisted coding tools in a production environment
• Strong collaboration skills across Product, Design, Backend, and ML teams
• Experience operating within cloud-based, CI/CD-driven environments

Why This Role is Exciting:

• Own frontend architecture at Staff level
• Shape how enterprise users interact with AI systems in production
• Join during a high-growth scaling phase with meaningful influence
• Work on genuinely complex technical problems at the intersection of AI and enterprise software
Have real impact on technical direction, product experience, and engineering culture
