Entry-level software engineer jobs in San Francisco, CA

About the role

This is a founding engineering role at an early-stage construction technology startup building the AI intelligence layer that transforms messy blueprints, permits, and construction documents into actionable cost estimates and permit workflows. You will work at the intersection of computer vision, multimodal AI, and real-world document understanding, with direct impact on housing, hospitals, and schools. You will be one of the earliest technical hires, shaping both the product and the engineering culture.

What you'll bring

• Hands-on experience applying computer vision, multimodal AI, and LLM techniques in production on real-world or document-based data.
• A 0-to-1 builder mindset: experience shipping AI systems or core product features into production.
• Comfort iterating quickly on prototypes based on user feedback in a startup or early-stage environment.
• Experience with end-to-end AI systems focused on the intelligence layer, not just the application layer.
• Willingness to take on practical, unglamorous engineering work as needed on a small team.
• Strong communication skills, a growth mindset, and an honest, empathetic approach to collaboration.
• New graduates and early-career engineers are welcome to apply.
• Candidates must be based in San Francisco or willing to relocate.
• Construction domain knowledge is a plus but not required.
