Job Description

Senior Machine Learning Engineer – AI/LLM Ops

Own, build and optimise LLM-powered AI solutions from the ground up.

This isn’t just another ML role —as the Senior AI Engineer you’ll shape the product. You’ll working with the latest AI tech in a fast-moving, high-impact startup team.

What You’ll Do:

• Deploy & optimise LLMs, NLP, and AI pipelines in production.
• Build scalable, efficient ML workflows (AWS/GCP, Kubernetes, LangFuse, Agenta).
• Solve real-world AI challenges — not just churning out tickets.
• System designers & builders — we want problem-solvers, not just theorists.
• Work cross-functionally to turn AI into real business impact.

What We’re Looking For:

• Deep Python expertise (multi-threading, decorators, optimisation).
• MLOps experience — building & deploying AI at scale.
• Entrepreneurial mindset — self-starters who challenge ideas.
• Strong AI/LLM problem-solving skills, not just model fine-tuning.
• Hybrid role (1-2 days in-office) — when it makes common sense.

If you want to own & shape a greenfield AI product, let’s talk.
