Job description

MCS Group is looking for a Data Engineer (AI) with a passion for IoT, to work on a greenfield AI initiative with our client in Belfast. This Data Engineer (AI) will work with a truly future focused technology company, working on their next generation of IoT and intelligent platforms and helping to shape their AI-enabled future. This Data Engineer will be central to building the data infrastructure and frameworks that power AI features across a cutting-edge hardware and IoT platform

This is a rare opportunity to join a product-driven organisation that operates like a start-up - agile, fast-moving, and empowered - but with the backing and stability of a larger company.

The Role

• You’ll design and deliver scalable data pipelines, support AI model training and deployment, and help define the data architecture that underpins advanced analytics and intelligent features.
• This is not a maintenance or executor role - it’s a chance to take a lead role in planning, designing, and implementing data systems that will bring AI in-house and drive real product innovation.
• Work with a range of data (e.g. video, field, GPS) from multiple IoT devices.
• Collaborate closely with AI/ML engineers and product teams to define data requirements and enable seamless AI integration.
• Develop tools, frameworks, and processes to ensure data quality, reliability, and performance.
• Implement monitoring and optimisation for data pipelines and streaming systems (latency, throughput, cost).
• Support customer-facing data insights and help explain AI behaviour and performance through data analysis.

The Person

• This role requires solid, demonstrable experience of Data Engineering, with experience building production-grade data pipelines and systems.
• Proficiency in Python and SQL is required.
• Ideally you will have a background working with IoT devices or video analytics, or other hardware-driven data environments.
• Hands‑on experience with AWS and associated cloud data tool is essential.
• Knowledge of frameworks such as Apache Airflow, Spark, Kafka, and/or MQTT.
• Experience with containerisation tools (Docker, Kubernetes).
• Strong understanding of data architecture, system design, and pipeline optimisation.

Nice to Have

• Experience with edge computing, real-time data processing, or streaming architectures.
• Exposure to AI/ML workflows or model lifecycle management.
• Familiarity with Kotlin or other modern programming languages.

Salary: £52k - £62k
Location: Belfast (approx. 2 days per week in the office)
