Description
Founded in Berlin, autarc is a ~40 person start-up who were part of Y Combinator’s S24 batch in San Francisco. Our team consists of people in Sales, Tech and Operations, with the Engineering & Product department currently ~20 people, as we continue to grow throughout the year.
This role is to join our AI team, where you will ship production AI features end-to-end across web/mobile clients and Backend services. This is an applied AI Engineering role: integrating modern models into reliable product workflows, not training models from scratch.
You will work on features such as Computer Vision workflows for energy installers, voice agents, AI-powered automations and help scale new Backend services being built in Go. Further responsibilities include building and owning AI-powered product features from UI to Backend, integrating LLM and multimodal API's (OpenAI, Anthropic, Mistral etc.) with structure outputs, guardrails and prompt/version management.
