Founded in 2002, we unite 2,400+ tech-savvy professionals across 40+ countries, working on impactful projects for industry leaders and Fortune 500 companies. Our expertise spans cloud, data, AI/ML, embedded software, IoT, and more, driving digital transformation across finance, manufacturing, telecom, healthcare, and other industries. Join N-iX and become part of a team where your ideas make a real impact.

We are looking for a Senior Machine Learning Engineer to lead the development and deployment of advanced AI models. In this role, you will be responsible for the end-to-end lifecycle of our machine learning systems, from architectural design and data preprocessing to model training, optimization, and production deployment. 

You will work at the intersection of generative AI and traditional machine learning, building the engines that power two strategic AI initiatives spanning NLP-based document intelligence and predictive analytics. Operating within a structured agile delivery model with formal review gates, you will ensure our models are not just accurate, but also robust, explainable, and deployable within highly secure, on-premise environments. 

Key Responsibilities:

  1. LLM & NLP Pipelines 
  • Design and fine-tune Large Language Model (LLM) pipelines to interpret complex regulatory texts (e.g. standards, building codes) and extract structured rules. 
  • Convert natural language requirements into computer-processable formats (e.g., logic tuples) that can be executed by downstream compliance engines. 
  • Implement RAG (Retrieval-Augmented Generation) architectures to enable semantic querying of technical documentation and historical project data. 
  • Optimize prompt strategies (few-shot learning, chain-of-thought) to improve model performance on domain-specific tasks without extensive retraining.
  1. Predictive & Analytical Models (Supply Chain) 
  • Develop time-series forecasting models to predict material demand and spend categories, integrating internal ERP data with external market signals. 
  • Build classification and anomaly detection models to assess supplier risk profiles based on financial health, delivery performance, and geopolitical factors. 
  • Design algorithms for multi-objective optimization(e.g., balancing cost vs. lead time vs. risk) to support procurement decision-making. 
  1. MLOps & Productionization 
  • Containerize models using Docker/Kubernetes and deploy them into secure, on-premise inference environments. 
  • Build automated training and inference pipelines using tools like Kubeflow or MLflow to ensure reproducibility and scalability. 
  • Optimize model inference latency and resource usage (e.g., quantization, distillation) to run efficiently on available hardware. 
  • Implement monitoring systems to track model drift and performance in production, establishing feedback loops for continuous improvement. 

Requirements:

  •  5+ years of experience in Machine Learning Engineering, with a proven track record of deploying models into production environments. 
  • Expert proficiency in Python and standard ML libraries (PyTorch, TensorFlow, Scikit-learn, Pandas, NumPy). 
  • Strong experience with transformer architectures (BERT, GPT, Llama) and NLP frameworks (Hugging Face, LangChain). 
  • Proficiency with MLOps tools and practices, including containerization (Docker), orchestration (Kubernetes), and experiment tracking (MLflow). 
  • Ability to design data preprocessing pipelines for both structured (SQL, tabular) and unstructured (text, PDF) data. 
  • Strong grasp of algorithmic principles for implementing custom logic, such as graph traversal or geometric computations.
  • Ability to quickly learn and apply ML techniques to specialized domains like engineering, supply chain, or other highly regulated industries. 
  • Experience working in agile environments (Sprints) while adhering to rigorous engineering standards and documentation requirements.
  • Strong communication skills to work effectively with Data Scientists, Backend Engineers, and Domain Experts to align technical solutions with business needs. 

Why This Role? 

You will be building the intelligence that drives critical enterprise infrastructure. Your models will not just generate text or predictions; they will directly influence the design of complex industrial systems and the resilience of supply chains. If you are ready to apply advanced ML to tangible, high-stakes problems in a rigorous engineering environment, join us.

We offer*:

  • Flexible working format - remote, office-based or flexible
  • A competitive salary and good compensation package
  • Personalized career growth
  • Professional development tools (mentorship program, tech talks and trainings, centers of excellence, and more)
  • Active tech communities with regular knowledge sharing
  • Education reimbursement
  • Memorable anniversary presents
  • Corporate events and team buildings
  • Other location-specific benefits

What you need to know about the Belfast Tech Scene

If asked to name the birthplace of the RMS Titanic, you might not say Belfast. Similarly, if asked to name Europe's leading destination for foreign direct investment in new software development, Belfast might not come to mind. Yet, both are true. The city has emerged as a tech powerhouse, recently ranked among the best in the U.K. for tech careers — especially for software developers. It also leads the U.K. with the highest percentage of software development jobs advertised.
