Job description

Full Stack / AI Engineer

About the Role

We’re looking for a Full Stack / AI Engineer with 3–4 years of experience to join our team and help build the intelligence layer of modern manufacturing.

This is a zero-to-one role where you’ll take ownership of meaningful, ambiguous problems and build production AI agents used daily by sales teams, operators, and plant managers.

You’ll work across the full product stack—from frontend and backend development to AI agents, integrations, infrastructure, and product experiences.

What You’ll Work On

In your first 30 days, you may:

• Visit a customer plant or office to understand existing workflows and translate real-world challenges into product requirements.
• Build end-to-end AI agents for complex workflows such as quoting, pricing, inventory management, procurement, and scheduling.
• Plan and build integrations with ERP and CRM systems.
• Prototype new product features, test them with real customers, and iterate based on feedback.
• Design simple, high-impact product experiences.
• Build core product features across frontend and backend.
• Develop infrastructure that keeps AI agents reliable in real-world production environments.
• Evaluate, integrate, and deploy new AI capabilities and LLM models.

What We’re Looking For

• 3–4 years of professional software engineering experience, with strong full-stack development experience.
• Strong proficiency in TypeScript, React, and Next.js or similar modern web technologies.
• Experience building and shipping production-grade applications across frontend and backend.
• Hands‑on experience working with LLMs, AI APIs, AI agents, or AI-powered applications.
• Ability to take ownership of a feature or problem from concept → prototype → production.
• Comfortable working across different areas of the stack, including UI, backend services, APIs, databases, integrations, and AI workflows.
• Strong problem‑solving skills and the ability to work effectively in ambiguous, fast‑moving environments.
• Comfortable using AI‑assisted development tools to accelerate straightforward tasks while maintaining strong engineering judgment.
• Ability to explain complex technical systems clearly to both technical and non-technical audiences.
• Strong communication, collaboration, and product‑thinking skills.
• Based in San Francisco or willing to relocate.
• Comfortable working in person and collaborating closely with the team.

Our Tech Stack

Our stack is focused on helping us ship quickly:

• TypeScript
• Next.js
• React
• LLM-powered applications and AI agents
• OpenAI, Gemini, and Anthropic

We use a mix of models and choose the right one for each use case.

What You’ll Get

• Meaningful ownership over product features and core architecture.
• The opportunity to work on real-world AI applications in global manufacturing environments.
• Direct exposure to customers, plants, and operational challenges.
• Close collaboration with founders with deep industry and domain expertise.
• The opportunity to help shape our engineering culture and product.
• A fast-moving environment where you can see your work go from idea to production.
