We are looking for a Senior Software Engineer to join an exciting new Agentic AI / AI Experiences team building the next generation of intelligent software experiences at global scale.

This is a rare opportunity to join a newly established engineering team at the forefront of enterprise AI. You’ll be a strong backend/full-stack engineer working primarily with Python, TypeScript or JavaScript, building scalable production software and integrating AI capabilities including LLMs, RAG and agentic workflows.

You’ll work on production-grade systems that move beyond traditional chatbots, enabling AI to understand business processes, interact with enterprise systems, retrieve information, make decisions, and take meaningful actions on behalf of users.

The platform and products you’re helping build have the potential to reach millions of people, giving you the opportunity to work on challenging engineering problems where backend architecture, APIs, cloud, AI and real-world user experiences come together.

You’ll have significant ownership from design through production, working closely with product managers, business stakeholders and engineers to turn ambitious AI concepts into reliable, scalable products.

Why Join This Team

  • Join a new, rapidly growing AI team building the future of intelligent software

  • Build scalable backend and full-stack applications using Python, TypeScript, cloud, APIs and AI

  • Work with LLMs, RAG and agentic AI in real production environments

  • Own projects end-to-end and help shape the team’s technology and engineering culture

What You’ll Be Doing

  • Design and build scalable backend and full-stack applications incorporating AI capabilities

  • Develop production software using Python, TypeScript or JavaScript, integrating APIs, databases, LLMs and enterprise systems

  • Build and improve RAG solutions, AI agents and agentic workflows

  • Own features across the full SDLC, including architecture, development, deployment, testing and production

What We’re Looking For

  • Proven experience as a Senior Software Engineer, Backend Engineer or Full-Stack Engineer

  • Strong Python, TypeScript or JavaScript skills with solid backend engineering fundamentals

Salary & Benefits

  • Competitive base salary up to €95,000

  • Bonus up to 20%

  • Defined contribution pension scheme + more

  • Hybrid working model: 1 day a month in the Cork office

If you’re a strong backend/full-stack software engineer looking to build production AI systems and expand your career into LLMs and agentic AI, we’d love to hear from you.
