Sensi’s agentic OS platform fueled by care intelligence empowers care providers to deliver 24/7 superior senior care, optimize operations, and scale efficiently, freeing teams from the chaos and burnout. Backed by Insight.
About the role
Sensi runs a growing family of agents — voice, text and summarization — across multiple product lines serving home care agencies, seniors and their families. This role owns the prompts behind them. Not one agent, and not one narrow surface: you'll build new agents from the ground up for new use cases, and you'll own prompt quality across several products and several product managers at once.
What they're looking for
- Based in Austin - able to be in our downtown office a couple of days a week. We work closely with colleagues in Israel, so real overlap with both Austin and Israel hours matters
- Roughly 1–2 years of hands-on prompt engineering — genuinely writing, building and iterating on prompts yourself. This is a young field and we're not looking for a decade of it
- Evidence you've designed something, not just assessed it. The distinction matters to us: rating or ranking someone else's AI output is adjacent work, but it isn't this job
- Strong language and communication skills. A large part of this job is words — precision, tone, and explaining your reasoning to people who don't do what you do
- Familiarity with LLM APIs (OpenAI, Anthropic, etc.) and conversational frameworks (e.g., LangChain)
- Excellent writing and linguistic skills, with attention to tone, clarity, and cultural sensitivity
More about this role
Sensi.AI is transforming home care through agentic AI — and we're just getting started. Our AI listens, understands and surfaces what matters in the lives of older adults, so caregivers and families can act before a small change becomes a crisis. As a hyper-growth startup, every person here has an outsized hand in the product and a direct line to the people it helps.
You'll help design the way our AI actually talks to people.

Not one agent, and not one narrow surface: you'll build new agents from the ground up for new use cases, and you'll own prompt quality across several products and several product managers at once. It is a genuinely broad, dynamic remit for an individual contributor, and you'll have an experienced prompt engineer alongside you rather than being the only person thinking about this.
Concretely, that means writing and rewriting the prompts, designing the conversations, testing them against real recordings and transcripts, and iterating on what you find. You'll work...
