George: Senior Full-Stack Engineer (AI Products) – George (Onsite) posted by 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.
