Senior Full-Stack Engineer (AI Products) – George (Onsite) at Datafin Recruitment

ENVIRONMENT:


A fast-growing AI Product and InsurTech business is building next-generation AI agents that automate real customer interactions, decision support, and operational workflows within a highly regulated insurance environment.
They are looking for a Senior Full-Stack Engineer to help transform powerful AI systems into real, production-ready products that customers and internal teams rely on every day.
This is a highly hands-on, product-focused engineering role where you will own the full product stack, from frontend experiences and backend APIs to deployment pipelines, observability, and production feedback loops.
The ideal candidate will have 5+ years' full-stack development experience, proven experience shipping user-facing AI or LLM-powered products into production, and a strong understanding of building secure, reliable systems in environments where AI outputs are not always predictable.


DUTIES:


Design, build, and maintain production-grade AI-powered products used by customers and internal teams.
Develop modern frontend interfaces for AI-driven workflows, conversational experiences, and human-in-the-loop review systems.
Build scalable backend services, APIs, integrations, and orchestration layers connecting AI systems to core business platforms.
Design and implement REST and/or GraphQL APIs with strong authentication, validation, and access controls.
Build systems that gracefully handle streaming responses, variable latency, partial outputs, and non-deterministic AI behaviour.
Develop secure integration layers between AI products and enterprise platforms such as CRM, operational, and policy systems.
Implement observability, monitoring, logging, and feedback loops to continuously improve AI performance in production.
Own the full software lifecycle including architecture, development, testing, CI/CD, deployment, and production support.
Collaborate closely with Product, AI Engineering, Business, and Leadership teams to shape product direction.
Ensure all solutions meet security, compliance, and data governance requirements.
