Machine Learning Engineer


If you’re an ML Engineer who enjoys shipping and running AI systems in production more than spending your days experimenting with models, this could be a very good fit.


What’s in it for you?

  • Work on AI and LLM systems that are genuinely running in production
  • Own problems across development, infrastructure and deployment, rather than being boxed into one area
  • Build with modern GenAI technologies including RAG, agentic AI and LLMs
  • Significant exposure to AWS architecture, MLOps, CI/CD and observability
  • Freedom to improve how AI services are deployed, monitored and scaled
  • Opportunity to take increasing technical ownership and potentially step into a Senior/Lead role
  • Remote working with the option to spend time in the office


What you’ll be working on

  • Building and operating production AI/LLM services
  • Designing and scaling cloud infrastructure in AWS
  • Improving CI/CD, infrastructure-as-code and automated deployments
  • Developing and debugging Python services using tools such as FastAPI and Pydantic
  • Building production RAG pipelines, including embeddings, indexing, retrieval and reranking
  • Implementing monitoring, tracing and observability across AI services
  • Improving system reliability, performance, compute efficiency and cost
  • Owning technical problems from development and staging through to production


What we’re looking for

You’ll ideally have 4+ years of relevant engineering experience, although depth of experience matters more than an exact number.


The strongest fit will be someone with:

  • A background in ML Engineering, MLOps, Platform Engineering or Software Engineering
  • Strong Python development experience
  • Hands-on experience building and operating systems in AWS
  • Experience deploying and maintaining production ML or AI services
  • Good understanding of CI/CD, containers and infrastructure-as-code
  • Experience with monitoring and observability tools such as Grafana, CloudWatch, Langfuse or similar
  • Some practical exposure to LLMs, RAG, NLP or generative AI
  • The confidence to take ownership of production systems and help guide other engineers
