Founding Engineer

Job Summary

Build AI agents for field technicians to diagnose and sell 10x better.

About the role

We work 6 days a week and we ping each other every night. As Founding Software Engineer, you will be our first full-time engineer and play a pivotal role in shaping our product and technology stack from the ground up. You will work closely with the founding team to design and build features end-to-end, bringing new AI-driven capabilities to market.

Responsibilities

• Build full-stack features: Develop and ship core product functionality using our React Native mobile frontend and Python backend. Take features from idea to production, including UI, business logic, and cloud services.
• AI/ML integration: Collaborate on designing and integrating large language models (LLMs) and other AI models into our applications. Work on data collection, preprocessing, model training, fine-tuning, and deployment to improve diagnostics and automation.
• Data engineering: Handle enterprise customer data and APIs. Build data pipelines and tooling to clean, store, and analyze large datasets for model training and inference.
• Quality & optimization: Test and validate model performance, optimize code for efficiency, and ensure reliability at scale. Iterate based on feedback from real technician use-cases to continuously improve the product.
• End-to-end development: Take ownership of features across the stack – from designing robust backend services and database schemas to crafting intuitive mobile UI and experiences.
• Collaboration: Work closely with product, AI, and design teams to translate customer needs (e.g., faster HVAC diagnostics) into technical solutions. Communicate clearly and document your work to help the whole team stay in sync.

Requirements

• Experience with full-stack development using React Native and Python.
• Strong understanding of machine learning and AI concepts.
• Experience with data engineering and pipeline building.
• Ability to work independently and as part of a team.
