Lead Java Developer

Role Overview

The team is looking for a Lead Software Engineer to help build the next generation of intelligent, agentic products and platforms powering the Mastercard Virtual C-Suite. This is a hands‑on technical leadership role for an experienced engineer who combines strong software engineering fundamentals with practical experience building production‑ready AI systems.

You will lead the design and delivery of secure, scalable, and reliable agentic applications that can reason, orchestrate tools, interact with enterprise systems, and deliver measurable business value. You will work closely with Applied AI, Data Science, Product, Security, and Platform teams to move from concept to experimentation to governed production deployment.

This role will suit a builder who enjoys solving complex problems, working across disciplines, and helping teams deliver high‑quality software at pace. We are particularly interested in engineers who know how to use AI responsibly both within products and across the software development lifecycle to improve quality, productivity, engineering effectiveness, and delivery outcomes.

Based in Ireland, this role offers the opportunity to work on globally scaled products while collaborating with distributed teams across regions. We welcome candidates from a range of backgrounds and experiences who are excited by the opportunity to shape practical AI innovation in a regulated, high‑impact environment.

Position Responsibilities

• Lead hands‑on architecture, design, and implementation of agentic applications, AI‑powered services, and platform capabilities from concept through production.
• Define engineering patterns and best practices for production AI systems, including evaluation, monitoring, guardrails, resiliency, cost control, and rollback strategies.
• Drive end‑to‑end software delivery across the SDLC, from discovery and prototyping to testing, release, and production operations.
• Use engineering tools to accelerate design, coding, testing, documentation, troubleshooting, and delivery while maintaining strong engineering judgment and code quality standards.
• Champion an AI‑enabled SDLC by improving developer workflows, automation, test generation, code review quality, release confidence, and team productivity.
• Partner closely with Product, Applied AI, Data Science, and business stakeholders to translate ambiguous opportunities into scalable product capabilities.
• Provide technical leadership through architectural decisions, design reviews, code reviews, hands‑on contribution, and mentoring of engineers across the team.
• Build highly available, secure, and maintainable cloud‑native services with strong observability, performance, and operational readiness.
• Shape technical roadmaps, identify short‑ and long‑term platform needs, and influence architecture choices that enable scale, reuse, and faster delivery.
• Collaborate across teams and business units to solve complex business and engineering problems with practical, high‑impact solutions.
• Keep senior stakeholders informed of progress, risks, trade‑offs, and implementation decisions in a clear and concise manner.

Requirements

• Strong software engineering experience building scalable, secure, maintainable production systems, including experience leading complex technical initiatives end to end.
• Hands‑on experience building and shipping AI‑powered products or agentic applications using LLMs, orchestration frameworks, tool‑calling patterns, retrieval, and context‑aware workflows.
• Strong understanding of agentic system design, including planning, reasoning loops, workflow orchestration, memory, grounding, evaluation, safety, and human‑in‑the‑loop controls.
• Experience taking AI solutions from prototype to production with sound engineering discipline around reliability, observability, latency, cost, security, and governance.
• Experience with modern AI frameworks, SDKs, and tooling for building AI applications, agent workflows, and developer productivity use cases.
• Strong programming skills in one or more backend languages such as Java and Python, with the ability to write high‑quality, well‑tested, production‑ready code.
• Experience with modern front‑end frameworks such as React and/or Next.js for building intuitive product experiences would be beneficial.
• Experience building services in cloud‑native environments using Kubernetes and managed cloud services on AWS, Azure.
• Good understanding of APIs, distributed systems, event‑driven architectures, data pipelines, and integration patterns across enterprise platforms.
• Experience with CI/CD, automated testing, and engineering automation, including the ability to improve SDLC efficiency and release quality using AI tools.
• Practical experienc
