Skills

Requirements

What we're looking for

  • 6-9 years in software engineering with 3+ years in GenAI, building and shipping production systems in enterprise settings.
  • Strong proficiency in Python with production deployment experience - you write code that other engineers can maintain, test, and extend.
  • Solid AWS knowledge (CDK, Serverless, Bedrock) with production deployment experience; familiarity with other cloud platforms is a plus.
  • Hands-on experience with LLM providers and frameworks: Azure OpenAI, AWS Bedrock, Hugging Face, LangChain/LangGraph - and the judgment to know when to use a framework vs. build custom.
  • Deep expertise in agent frameworks (LangGraph, AutoGen, CrewAI) combined with the ability to build custom orchestration when off-the-shelf doesn't cut it.
  • University degree or equivalent experience in Computer Science, Engineering, or a related field.

The role

What you'll do

  • Implement agent features and integrations in production codebases - APIs, websockets, tool-calling workflows - following established architecture patterns, no low-code platforms.
  • Adapt and integrate pre-trained LLMs and embeddings into applications (prompting, fine-tuning, RAG pipelines) and keep them maintainable, testable, and observable over time.
  • Build self-verifying agent workflows with chain-of-verification, evaluator models, and human-in-the-loop escalation paths that make agents trustworthy in enterprise environments.
  • Create comprehensive agent observability - full audit trails, structured logging, performance metrics - so the team always knows what agents are doing and why.
  • Ship autonomous agents making real business decisions with 95%+ reliability, optimising the balance between reasoning depth, latency, and cost.
  • Embed with product teams to evolve agent capabilities based on real usage data, closing the loop between what's built and what actually works.

A Snapshot of Your Day

You know the difference between a demo and a product.

As a Senior AI Agent Developer at Siemens Energy's AI Factory, you'll implement agent features and integrations that go live in production - APIs, tool-calling workflows, multi-step reasoning chains - inside a company whose technologies help generate an estimated one-sixth of the world's electricity. Your code won't sit in a notebook. It will triage engineering emails, assist project managers on multi-billion-euro installations, and help field service teams maintain gas turbines across continents. This is a rare opportunity to truly transform the workplace with AI for thousands of employees & help support them manage the increased workload resulting from record breaking business growth - you'll help prove that a company with over 150 years of heritage can ship AI faster than most startups.
