Building AI products that genuinely impact the future of science DeepRec.ai are partnering with a global technology organisation operating at the intersection of AI, data, and life sciences to hire a Principal Software Engineer specialising in Generative AI.

This is a rare opportunity to move beyond prototypes and help build production‑grade AI systems that transform how scientists and enterprises interact with complex data.

You’ll be leading the design and delivery of GenAI capabilities across large‑scale platforms - taking ideas from concept through to real‑world adoption.

What you’ll be working on

• Architecting and deploying LLM‑powered applications
• Building AI systems around RAG, intelligent search, summarisation, and automation
• Designing scalable AI‑ready data architectures
• Taking GenAI solutions from PoC through to production
• Setting engineering standards for reliability, evaluation, monitoring, and performance
• Providing technical leadership across high‑performing engineering teams

We’d love to speak with engineers who have

• Strong software engineering foundations
• Hands‑on experience building with LLMs
• Knowledge of cloud‑native architectures
• A passion for applying AI to solve meaningful, complex problems

Bonus points for experience across

• AI governance, agents, or enterprise AI platforms

This isn’t another “add AI onto an existing product” role - this is about shaping how AI becomes embedded into mission‑critical platforms used globally.
