Senior Full Stack Engineer

Referment is working with an AI software company whose products support high-stakes research by investors, consultants and financial institutions. The team is looking for a senior engineer to own complete product features across user interfaces, backend services and data. You'll work directly with customers, make product and technical trade-offs, and turn emerging AI capabilities into dependable workflows. The remit combines hands-on delivery with influence over engineering culture as the team grows. The Role

• Lead features from problem definition through design, implementation and release.
• Build polished React and Next.js experiences alongside TypeScript services and PostgreSQL models.
• Create AI-enabled workflows for research ingestion, knowledge graphs, voice interaction and customer relationship data.
• Use customer conversations to refine priorities and improve shipped products.
• Contribute to system design, code quality and practical engineering standards. What We're Looking For
• At least five years of engineering experience with substantial end-to-end product ownership.
• Strong TypeScript, Next.js or React, and PostgreSQL expertise.
• Solid foundations in data structures, system design and relational data modelling.
• The judgement to decide what should be built and the pace to deliver without detailed specifications.
• Clear communication and enthusiasm for a client-facing role. Experience designing AI-powered products is helpful, but the central requirement is strong product engineering. This could suit a senior full-stack or product engineer who remains deeply hands-on and enjoys solving across the application rather than staying in one layer.
