Applied AI engineer

SiftHub is an Agentic Platform for Deal Orchestration. We deploy agents to automate sales collateral, deal briefs, RFPs, and post-meeting follow-ups; unblocking deals for sales and solutions teams.SiftHub collates and sifts through your ecosystem (Drive, Gong, CRM, Slack, and more) to identify and convert real-time deal signals into tailored content and ready-to-execute actions. Designed to replicate how top-performing reps execute deals. Trusted by revenue teams at Saviynt, Everlaw, Allego, Superhuman, Sirion and more.
Why This Role Exists
SiftHub's core value is the quality of the intelligence it surfaces to sales teams - delivered through a web app, Chrome extension, Microsoft add-in, and Google Sheets integration. That intelligence comes from a combination of retrieval, reasoning, and generation and it only works if every layer is built and evaluated with care. We need an Applied AI engineer who can design and own these pipelines end to end: not just get them working, but get them reliably good and measurably improving over time.
What You'll Own
End-to-end RAG pipelines: retrieval architecture, chunking strategy, re-ranking, and prompt design
Evaluation frameworks: defining quality metrics, building eval harnesses, and tracking pipeline health over time
Agentic workflows and LLM integration: multi-step reasoning, tool use, orchestration, model selection, context management, latency, and cost optimisation
Collaboration with Backend engineers to serve NLP outputs at production quality and latency
Research-to-production translation: staying current and knowing what’s worth shipping
Experience & Core Skills
Bachelor’s or Master’s degree in Computer Science or a related field, or equivalent practical experience
