Software Engineer, AI Research & Prototyping

Sage Care is a fast-growing, early-stage healthcare startup transforming healthcare through AI innovations. They are seeking a Software Engineer to design experiments and build prototypes that enhance their voice AI capabilities and support the team with knowledge transfer and evidence-based recommendations.

Responsibilities:

• Track emerging techniques in voice AI, LLM reasoning, and agent systems, and identify which ones matter for us
• Design structured experiments with real controls: know when a result is signal and when it is noise
• Build rapid prototypes and test them against real conversation data
• Run head-to-head evaluations of models, providers, and techniques (reasoning approaches, speech models, orchestration patterns)
• Turn every investigation into a team-usable artifact: a benchmark, a written deep-dive, a tech talk, or a recommendation with evidence
• Work with platform engineers to hand off validated ideas for production implementation
• Build the internal knowledge base for how and why our AI stack works the way it does
