Senior AI/ML Engineer - Data Science & AI

The Team and Your Role

We're a tight-knit, diverse team that believes AI innovation is at the heart of creating value with intelligent solutions. We're seeking a Senior AI/ML Engineer to design and build backend services and LLM-powered features in a cloud environment. You'll own complex systems, set technical direction within the team, mentor less experienced engineers, and turn open-ended problems into clear requirements, in a collaborative environment where people feel comfortable bringing their authentic selves to work.

Location: For this role, we are looking for candidates who are able to work onsite in our Galway office two to three days per week.

What You Will Do

• Design and build backend APIs and services in the cloud (AWS preferred), lead design discussions, contribute to High Level Architecture documents, and make and justify technical decisions with security and privacy in mind
• Write clear specifications and use them to generate, test and validate code, and build LLM-based features including prompt design, structured outputs and evaluation of model behaviour
• Lead the design and delivery of features from open-ended problem to production, clarify requirements with Product Managers and other partners, and raise delivery risks early
• Lead operational reliability (deployments, monitoring, incident response), improve CI/CD pipelines, and optimize performance and maintainability through refactoring
• Mentor junior engineers, and set and uphold coding standards and best practices through code reviews

Required Skills & Experience

• University degree in Computer Science, AI/ML, Data Science, or related field (or equivalent experience), with 5+ years of software or AI/ML engineering experience, and the ability to solve complex technical problems independently within the team's domain
• Strong Python or Java skills, proven experience designing and building RESTful APIs and microservices, and solid working knowledge of cloud services (AWS preferred) including serverless computing, with proficiency in CI/CD tooling, Git and a testing-first approach
• Ability to write clear specifications and use them to generate, test and validate code, and to model and validate structured data such as schemas, policies and constraints
• Hands-on experience building with large language models, including prompt design, structured outputs and evaluating model behaviour, applying responsible AI practices for secure, reliable and responsible system behaviour
• Ability to explain technical trade-offs in plain language to PM, UX and other partners, turn open-ended problems into clear requirements, and mentor engineers while influencing decisions within the team

Desirable Skills & Experience

The following would be great additions but are not required:

• Experience with tool-using AI agents, multi-agent frameworks or workflow orchestration
• Experience with contact centre or customer experience platforms
• Experience with MLOps practices for deploying AI systems at scale, and with fine-tuning or adapting models
• Experience with data streaming platforms (Kafka) and event-driven design
• An awkward sense of humour and collaborative mindset (we appreciate authenticity and diverse perspectives in AI!)
