The Role We're building Interfaze, the first LLM purpose-built for deterministic developer tasks. As a founding full stack engineer, you'll architect and ship the systems that let developers replace expensive, slow frontier models with specialized alternatives—processing over 10 million API requests and counting. You'll own critical infrastructure pieces while directly shaping the product developers use daily.
What You'll Do
What We're Looking For
JigsawStack (now rebranding as Interfaze) is an AI infrastructure startup providing a unified SDK and API suite of purpose-built small models designed to automate high-maintenance backend developer tasks including web scraping, OCR, translation, speech-to-text, and classification. The company's flagship evolution, Interfaze, is positioned as 'the world's first LLM built for deterministic developer tasks,' combining heterogeneous deep neural networks, small language models, and a context-construction layer into a single OpenAI-compatible API. Founded in January 2024, the company was accepted into Y Combinator's Spring 2026 batch and has processed over 10 million API requests since its beta launch.
