Job description

Python/AI Software Engineer

MCS Group are delighted to be partnering with a global organisation investing heavily in AI, automation and next-generation technology as they continue to build out their Belfast technology function.

Due to continued growth, they are hiring for both an AI Engineer and Senior AI Engineer to join a highly visible team working on enterprise-scale AI initiatives across a global business.

This role could be particularly well suited to a strong Python Software Engineer who has started moving into AI engineering and is looking to take that experience further. You don't need to come from a traditional Data Science or Machine Learning background - strong software engineering fundamentals combined with hands-on experience building AI solutions, working with LLMs or integrating AI into applications could be a great fit.

You'll have the opportunity to work on genuinely cutting-edge projects in a business where AI is becoming a key part of the wider technology strategy. The team are focused on building practical AI solutions that improve internal operations, automation, knowledge management and user experience across the organisation.

The environment would suit someone who enjoys being hands-on technically, solving complex problems and working with stakeholders to turn new AI capabilities into real-world solutions.

The Role

You will work as part of a growing AI engineering function focused on designing, building and improving AI-driven applications and platforms across the business.

Projects currently include:

• Generative AI and LLM applications

• AI-powered automation

• Integrating AI capabilities into existing software platforms

• Machine learning solutions

• AI platform and application engineering

• Data-driven process improvement

• AI governance, optimisation and experimentation

• Building APIs and scalable services around AI solutions

The team are looking for engineers who can take ideas from proof of concept through to production, with a strong focus on building reliable, scalable and maintainable software.

At Senior level, you'll also have the opportunity to provide technical leadership, mentor other engineers, work closely with stakeholders and help shape engineering standards and best practice across AI delivery.

What You'll Need

We're particularly interested in speaking with people who have a strong Python software engineering background and some commercial, hands-on experience working with AI.

You may come from an AI Engineering, Software Engineering, Machine Learning or Data Engineering background.

Ideally, you'll have:

• Strong commercial experience with Python

• Experience building production-quality software, APIs or applications

• Some hands-on experience with AI / ML / Generative AI

• Experience working with LLMs, AI APIs, AI agents or AI-enabled applications would be highly beneficial

• Exposure to modern AI/ML frameworks and tooling

• Experience working with AWS or Azure

• Understanding of software engineering best practices, including testing, version control and deployment

• Experience working with cloud-based or scalable applications

• Strong problem-solving skills and a genuine interest in how AI can be applied to real-world business problems

• Good communication skills and the ability to work with both technical and non-technical stakeholders

This is not a Data Scientist or Machine Learning Engineer. If you're a strong Software Engineer with Python expertise who has gained genuine hands-on AI experience and wants to move further into AI engineering, we'd be very interested in speaking with you.

Tech Environment

The team work across a modern technology stack, with exposure to areas including:

• Python

• AWS / Azure

• Generative AI & LLMs

• AI APIs and tooling

• TensorFlow / PyTorch / scikit-learn

• AI automation and agent frameworks

• REST APIs and platform engineering

• Cloud-native development and deployment

You won't necessarily need experience across the full stack above - strong Python engineering ability and practical AI experience are the key requirements.

Why This Role?

• Join a global organisation making significant investment in AI and emerging technology

• Work on real-world AI projects with tangible business impact

• Opportunity to work across both software engineering and AI

• Excellent opportunity for a Software Engineer looking to build a career in AI Engineering

• Large-scale global projects and technically interesting challenges

• Strong career progression and development opportunities

• Collaborative engineering culture

• Hybrid working

• Belfast-based technology hub with significant long-term growth plans

Salary will depend on experience, with opportunities available at both AI Engineer and Senior AI Engineer level.

All conversations will be treated in the strictest confidence.
