Founding Engineer

About the Role

Join an early-stage B2B SaaS team building AI tools for industrial ingredient manufacturers. As a senior, hands-on engineering hire, you will work closely with company leadership to build products that streamline document-heavy operational and compliance workflows.

What You'll Do

• Build backend systems that ingest and process documents from customer business systems and inboxes.

• Develop AI agents that complete complex, multi-page compliance and food safety documents.

• Own products end to end, from customer discovery and problem definition through architecture, launch, and iteration based on real usage.

• Ship and refine features quickly in response to user feedback.

• Contribute across frontend, backend, infrastructure, and product decisions.

What We're Looking For

• At least 4 years of professional software engineering experience, with substantial early-stage startup experience as a founder, co-founder, CTO, VP of Engineering, or engineering leader.

• A deliberate interest in returning to a hands-on individual contributor role, with recent experience writing and shipping production code.

• Experience owning and launching full-stack products from customer problem through production use and iteration.

• Strong product judgment and the ability to build across backend, frontend, and infrastructure.

• Production experience with AI or LLM products, agents, or automation.

• Backend experience with data ingestion and processing, plus relational database design such as Postgres.

• The team uses Kotlin, Spring Boot, React, Next.js, Postgres, GCP, and models from providers including Gemini and Anthropic. Experience with these tools is helpful, and engineers from other stacks should be ready to learn.

• Interest in document processing, supply chains, manufacturing, or other traditional industries is valuable.
