About the role

AI summarised

The Algorithm & ML Staff Engineer at Thermo Fisher Scientific will design and deploy production-grade LLM-powered agent systems, including chatbots and copilots, with a focus on safety, performance, and scalability. This role involves owning the full product lifecycle from prototyping to monitoring, collaborating across software, hardware, and data science teams, and mentoring junior engineers in LLM engineering best practices. The position requires strong expertise in RAG pipelines, context engineering, MCP integration, and AI safety controls, with preferred experience in biotechnology and AWS AI services.

Key Responsibilities

  • Architect, build and deploy LLM powered agent systems (chatbots, copilots, agents) that are safe, fast, and cost-efficient
  • Own the whole product development life cycle: build → prototype → evaluate → harden → monitor
  • Build retrieval-augmented generation (RAG) pipelines (indexing, chunking, embeddings, reranking, grounding)
  • Apply context engineering (prompt design, tool calling, memory, compression, window strategy)
  • Integrate tools through Model Context Protocol (MCP) and other agent frameworks
  • Design and deploy production-grade chatbots with multi-turn conversation flows, escalation mechanisms, and integrated safety guardrails for seamless use across web, mobile, and internal platforms
  • Implement risk controls (safety filters, jailbreak resistance, PII redaction, abuse detection, audit logs)
  • Optimize performance (latency, efficiency, token/cost budgets, streaming, caching, model routing)
  • Establish evaluation: golden sets, RAG/grounding scores, toxicity, A/B tests, latency & cost benchmarks
  • Operate in production: tracing, prompt/version lineage, drift detection, incident response, SLOs
  • Collaborate with cross-functional teams, including software, hardware, and data science, to ensure algorithms meet product requirements and are well-integrated into production systems
  • Mentor junior AI engineers, set coding standards and documentation, and advocate for guidelines in LLM engineering including reproducibility, ensuring algorithm reliability and transparency

Requirements

  • Master’s degree in Computer Sciences, Mathematics, Statistics, Bioinformatics or a related field
  • Ph.D or equivalent experience is highly preferred
  • 5+ years of hands-on experience in production-level chatbots development
  • At least 1 year experience in building LLM-based agents
  • Hands-on with major LLMs
