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
