Lead Full Stack Engineer

is harnessing the power of artificial intelligence to revolutionize the plastic and plastic compounding industries, bridging the gap between engineers using plastics and manufacturers creating them. At the core of our platform is Herman, an advanced AI agent designed to match product requirements with ideal plastic compounds. Herman leverages a combination of public and proprietary data to enable rapid and precise material recommendation, which can be easily ordered within a marketplace.

We are looking for a skilled Lead Full-stack Software Engineer to play a key role in building the Agentic AI infrastructure for tool calls, data engineering, and interfaces that make Herman accessible to engineers and manufacturing companies. In this role, you will primarily drive and implement the design, development, testing, and delivery of UI features that expose the portfolio's rich capabilities to users while providing exceptional, easy-to-use experiences.

Our ideal candidate has more experience in back-end development but can interface with the entire stack to enable rapid feature deployment. We see a combination of these skills as crucial for helping us meld our novel user experiences with AI Agents to enable easy plastic selection, sourcing, and logistics. This transformative approach unlocks new possibilities in plastics innovation, enabling faster, smarter, and more efficient product development and material discovery.

As part of our cross-disciplinary team, you will work alongside MIT-trained engineers, scientists, and business professionals to build a groundbreaking AI platform for the plastics industry. Join us in transforming how the world approaches plastic materials through cutting-edge technology and innovation.
