Reporting to: Lead Developer
Company Overview
Wyser is a dynamic and innovative digital transformation company that helps organisations improve their efficiency and productivity through the use of responsible AI. Wyser designs, builds and operates production AI systems for regulated and frontline services. Wyser is currently seeking a skilled Machine Learning Engineer who can assist with readying and supporting our models from inception to production.
Job Responsibilities
We require someone to develop, deploy and support AI models in all parts of the AI life cycle:
- Design, implement and improve LLM application pipelines for speech-to-text, structured summarisation / information extraction, document classification and retrieval-augmented generation.
- Build and tune hybrid RAG systems over documents and transcripts.
- Integrate and operate third-party AI services, including Google’s Gemini Agent Enterprise Platform (Gemini), speech providers (e.g. AssemblyAI, ElevenLabs, DeepGram), Azure Document Intelligence and embedding models, with multi-tenant configuration.
- Own evaluation and quality loops: regression test matrices, STT benchmarking (WER/CER), feedback triage, prompt / schema iteration, and release gates for accuracy-sensitive features.
- Collaborate with product, engineering and data science to turn domain requirements into robust ML behaviour.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
