Product Engineer

Product Engineer (Full Stack) – AI SaaS Startup - London (SE1) - £50k to £65k

Avanti Recruitment is working with a high-growth London-based SaaS startup building an AI-driven platform used by commercial teams to manage and close complex deals.

They’re looking for a Product Engineer who genuinely cares about what gets built, how it works, and the impact it has on users.

Why this role stands out

• This is a proper product engineering environment
• Engineers own features end-to-end
• You’ll work directly with product and design
• You’re encouraged to challenge ideas and shape solutions
• Fast iteration, real user feedback, and visible impact

The team is small, collaborative, and high-energy. It’s a genuinely strong culture; social, supportive, and full of personality without being forced. Most people come into the office 2–3 days a week because they want to, not because they have to.

You’ll be working closely with an experienced and highly approachable Director of Engineering who’s big on autonomy, trust, and building a team people actually enjoy being part of.

There’s a big push into AI and automation, including:

• Integrating GenAI into product workflows
• Exploring LLM and RAG-based features
• Using AI to improve both user experience and internal processes

They’re looking for someone who wants to grow with the business long-term.

Tech stack

• Next.js / React / TypeScript
• Node.js
• AWS
• Modern API-driven architecture

If you’re looking for a role where you can own what you build, work on genuinely interesting AI-driven features, and be part of a team that actually enjoys working together, this will be a great opportunity.
