Make your mark as a Machine Learning Software Engineer in the AI & Technology sector, based in Belfast.
Belfast's tech scene has quietly become one of the UK's more interesting places to build AI products, and this startup is part of why.
It's a small, fast-moving team working on genuine machine learning problems rather than bolting a chatbot onto an existing product.
The next Machine Learning Software Engineer through the door will have real influence over what gets built and how.
This isn't a role where you sit in one lane.
You'll write production code, shape model architecture decisions, and see your work ship within weeks rather than quarters.
That pace suits someone who wants ownership early in their career rather than waiting years for it.
Here's what you'll be doing: Design, train, and deploy machine learning models that solve specific product problems, not just research exercises Build and maintain the pipelines that get data from raw source to model-ready, cleanly and reliably Write production-grade Python code and work closely with backend engineers to get models live Monitor model performance after deployment and iterate fast when something underperforms Contribute to technical decisions across the stack, since a flat structure means your opinion counts from day one Document your work clearly enough that a teammate can pick it up without you in the room Here are the skills you'll need: Solid experience with Python and at least one major ML framework (PyTorch or TensorFlow) A working understanding of the full ML lifecycle, from data prep through to deployment and monitoring Comfort with cloud infrastructure (AWS, GCP, or Azure) and basic MLOps practices Good instincts for when a simpler model beats a fancier one.
Mid-level judgement, not just technical range Strong communication skills.
You'll need to explain model behaviour to people who don't live in the weeds with you Genuine curiosity.
Startups reward people who ask "why" before they ask "how" Key perks and benefits: Salary of £47,000 to £62,500, depending on experience Equity in the business.
If it grows, you grow with it Hybrid working from Belfast, with flexible hours built around how you actually work best A dedicated learning and development budget, because this field moves fast and so should you Remote-friendly culture for days when the best work happens away from a desk Why pursue a career in AI & Technology?
AI & Technology isn't slowing down, and the engineers who get in now, at mid-level, are the ones who'll be leading teams in five years.
Belfast has built a genuine cluster of AI & Technology talent and investment, so you're not isolated from the wider industry just because you're not in London.
Good machine learning engineers are still scarce.
That scarcity tends to reward the people who show up and do the work properly.
