We’re working with a fast-growing AI startup building software that’s transforming how large industrial and infrastructure companies operate. This isn’t another chatbot, it’s AI applied to real-world environments where efficiency, safety, and decision-making matter.

They’ve already secured major enterprise customers and are heading into Series A with strong product-market fit and rapid growth.

The Role

This is a highly product-focused full stack role with true end-to-end ownership. You won’t be picking up tickets, you’ll be speaking directly with users, defining problems, designing solutions, and shipping them.

You’ll be working on systems that:

• Turn voice, images, and field data into structured outputs using AI
• Handle large volumes of unstructured data and context
• Power workflows used in complex, real-world environments
• Balance offline/online functionality in challenging conditions

What You’ll Be Doing

• Working directly with users to understand workflows and pain points
• Designing and building full-stack features from scratch
• Architecting systems that integrate AI into real-world use cases
• Improving how data is captured, processed, and surfaced
• Shaping product direction alongside founders

What We’re Looking For

• 3+ years experience as a full stack engineer
• Strong product mindset and ownership mentality
• Experience building and shipping end-to-end systems
• Comfortable working with ambiguity and making decisions
• Interest in AI-driven products and real-world applications
