Job Overview

At iCIMS, we’re transforming how talent connects with opportunity through intelligent, human‑centered technology. We’re seeking a Principal Data Scientist to play a pivotal role in advancing the AI capabilities that power our Talent Cloud platform. In this role, you will architect sophisticated ML solutions, lead complex initiatives, and partner closely with engineering and product teams to drive meaningful innovation across our GenAI, LLM, agentic AI, and NLP‑based systems.

You will operate as a senior technical expert - deeply hands‑on while influencing major product and platform decisions. You’ll mentor data scientists and ML engineers, guide best practices, and contribute to an experimentation culture grounded in scalable, responsible, and production‑ready AI.

This hybrid role is based at our AI development hub at Windmill Lane, Dublin 2.

About Us

When you join iCIMS, you join the team helping global companies transform business and the world through the power of talent. Our customers do amazing things: design rocket ships, create vaccines, deliver consumer goods globally, overnight, with a smile. As the Talent Cloud company, we empower these organizations to attract, engage, hire, and advance the right talent. We’re passionate about helping companies build a diverse, winning workforce and about building our home team. We're dedicated to fostering an inclusive, purpose-driven, and innovative work environment where everyone belongs.

Responsibilities

Architect, design, and implement large‑scale AI/ML systems spanning NLP, deep learning, generative AI, agentic frameworks, and RAG‑based pipelines.
Develop production‑grade model training, evaluation, and monitoring workflows that support scalable, repeatable deployments.
Build and enhance automated data processing frameworks, including ingestion, cleaning, transformation, feature engineering, and validation.
Lead major AI‑driven projects in close collaboration with engineering, product management, user experience, and platform teams.
Provide senior‑level technical mentorship to data scientists, ML engineers, and cross‑functional partners, elevating modeling rigor and engineering excellence.
Establish and refine best practices related to ML reproducibility, model governance, observability, fairness, and responsible AI principles.
Conduct applied research on emerging ML methods—including LLM adaptation, prompting strategies, model optimization, vector search/RAG, and agent‑based orchestration—and translate findings into high‑impact product capabilities.
Prototype, experiment, evaluate, and operationalize new AI features, contributing to the advancement of our AI/ML roadmap.
Present technical insights, modeling results, and architectural recommendations to senior leadership and contribute to roadmap prioritization.
Support product teams in identifying opportunities for AI integration, offering guidance on feasibility, complexity, and expected value.
Collaborate with platform and infrastructure teams to ensure models and pipelines meet performance, reliability, and scalability expectations.
Participate in external knowledge‑sharing opportunities, contributing to iCIMS’ reputation in the AI/ML community when appropriate.

Qualifications

Bachelor’s degree in Data Science, Computer Science, Machine Learning, Statistics, Engineering, or a related technical field (or equivalent professional experience).
10+ years of hands‑on experience developing machine learning, deep learning, NLP, or generative AI systems in production environments.
Proven experience leading complex AI/ML initiatives from initial research through deployment.
Strong software engineering skills, including experience with distributed systems, scalable ML infrastructure, and MLOps workflows.
Demonstrated ability to mentor technical contributors and collaborate effectively with cross‑functional peers.
Strong communication skills with the ability to translate technical concepts into business‑oriented insights and influence decision‑making.
Strong analytical thinking, experimentation discipline, and problem‑solving capabilities
