Role Title: Machine Learning Engineer

Location: Dublin, Republic of Ireland (Flexible hybrid working)

Employment Type: Permanent

Summary of the role:

EXL Digital is looking for an experienced Machine Learning Engineer to join our team. At EXL, we believe there is always a better way. We look deeper, we find it, and we make it happen. We've built a culture founded on core values of innovation, collaboration, excellence, integrity, and respect.

In this role, you will design, build, and operate machine learning and GenAI systems that power our products and client solutions. You'll work with product, engineering, and client stakeholders to identify high-impact opportunities, rapidly prototype solutions, and harden them into scalable, secure, and cost-effective production systems. You'll also help set ML engineering standards across the team, from data quality and evaluation rigor to MLOps and responsible AI practices.

As part of your duties, you will be responsible for:

• Design, build, and deploy machine learning models and GenAI solutions that solve real business problems, from problem framing and data exploration through production deployment and monitoring.
• Develop end-to-end ML pipelines covering data ingestion, feature engineering, training, evaluation, deployment, and retraining, using orchestration tools such as Apache Airflow.
• Build and productionize GenAI applications, including LLM integration, prompt engineering, RAG (retrieval-augmented generation) pipelines, embeddings, vector databases, and agentic workflows.
• Fine-tune, evaluate, and optimize models (classical ML, deep learning, and LLMs) for accuracy, latency, and cost.
• Deploy and operate models in production on AWS (or comparable cloud platforms) using services such as SageMaker, Bedrock, Lambda, and containerized inference.
• Implement MLOps best practices: experiment tracking, model versioning, CI/CD for ML, automated testing, monitoring for drift and performance degradation.
• Work with large, messy, real-world datasets: design data pipelines, ensure data quality, and build robust feature stores in partnership with data engineering.
• Establish evaluation frameworks for both traditional models (precision/recall, AUC, calibration) and LLM-based systems (grounding, hallucination rates, task success metrics).
• Embed responsible AI practices: fairness, explainability, privacy, and security, into model development and deployment.
• Collaborate with product managers, architects, and client stakeholders to translate business requirements into ML solutions with measurable impact.
• Write clean, well-tested, production-quality code and participate in design and code reviews.
• Build proof-of-concepts to validate ML/GenAI approaches quickly, and harden successful experiments into production systems.
• Mentor junior engineers and data scientists on ML engineering best practices.
• Stay current with the rapidly evolving ML/GenAI landscape and recommend adoption of new models, frameworks, and techniques where they add business value.

Qualifications and experience we consider to be essential for the role:

• Minimum 5 years of software or data engineering experience, with at least 3 years building and deploying machine learning models in production.
• Strong programming skills in Python and hands-on experience with ML frameworks such as scikit-learn, PyTorch, or TensorFlow.
• Practical experience building GenAI/LLM applications: prompt engineering, RAG pipelines, embeddings, vector databases (e.g., pgvector, Pinecone, OpenSearch), and LLM APIs (OpenAI, Anthropic, Bedrock).
• Solid grounding in ML fundamentals: supervised/unsupervised learning, feature engineering, model evaluation, and error analysis.
• Experience deploying and operating models on AWS (or comparable cloud): SageMaker, Bedrock, Lambda, ECS/EKS, or equivalent services.
• Working knowledge of MLOps tooling: experiment tracking (MLflow, Weights & Biases), model registries, pipeline orchestration (Apache Airflow, Kubeflow, or Step Functions), and monitoring.
• Strong data skills: SQL, workflow orchestration with Apache Airflow, and experience with relational (PostgreSQL, MySQL) and NoSQL data stores; exposure to Spark or similar big-data tools is a plus.
• Experience exposing models as services: REST/GraphQL APIs, batch and real-time inference, and integration with backend applications.
• Solid software engineering fundamentals: version control, testing, CI/CD, containers (Docker/Kubernetes), and code review practices.
• Understanding of responsible AI concepts: bias, explainability, privacy, and security considerations in ML systems.
• Experience working in Agile/SCRUM environments and delivering iteratively.
• Excellent communication skills, with the ability to explain models, trade-offs, and results to both technical and non-technical audiences.
• Ability to work with stakeholders across multiple geographies.

As part of a leading global Data and AI company, you can look forward to:

• A competitive salary with a generous bonus, private healthcare, life assurance at 4 x your annual salary, income protection insurance, and a rewarding pension.
• At EXL, we are committed to providing our employees with the tools and resources they need to succeed and excel in their careers. We offer a wide range of professional and personal development opportunities. We also support a range of learning initiatives that allow our employees to build on their existing skills and knowledge. From online courses to seminars and workshops, our employees have the opportunity to enhance their skills and stay up to date with the latest trends and technologies.
• As an Equal Opportunity Employer, EXL is committed to diversity. Our company does not discriminate based on race, religion, colour, national origin, sex (including pregnancy, childbirth, or related medical conditions), sexual orientation, age, or disability status.
• At EXL, we offer a flexible hybrid working model that allows employees to live a balanced, healthy lifestyle while strengthening our culture of collaboration.

To be considered for this role, you must already be eligible to work in the Republic of Ireland.
