Founding Engineer

Planbase is building the AI-native operations layer that will power every modern clinic in the U.S.

• We’re already the operational backbone for multiple healthcare organizations valued at over $1B.
• 5,000+ doctors delivering care to 100M+ patients are scheduled weekly through Planbase.
• Customers love us. Our top sales channel is unprompted referrals.

We’re hiring founding engineers to help build the infrastructure behind the next generation of B2B software. This is a high-ownership role: you’ll work directly with the founders to shape the product, the company, and the way healthcare and staffing operations are run.

You’ll be among the first employees at an early-stage startup, which means challenge, uncertainty, and opportunity. This role isn’t for everyone — to be a good fit, you need to be hungry to move build, break and push boundaries.

What you’ll do

• Ship fast, talk to customers, and build AI agents that automate complex tasks in healthcare
• Work across the stack — from building AI agents to delivering elegant user-facing features.
• Build the platform infrastructure that allows AI to generate customer-specific apps, reports, insights and workflows.
• Help define engineering culture and grow the team.

What kind of person we’re looking for

• High-energy, opinionated, and fun to work with.
• You must have experience building complex products to hit the ground running.
• Strong product taste.
• You’ve built real products for real customers, not just internal tools, integrations or side projects.
• You move quickly but maintain a high bar for quality — and expect the same from those around you.
• You want to help build not just a product, but a company and a category-defining business.
• Visa required but open to O-1 visa sponsorship for exceptional candidates (e.g., top-20 university, publications, or press). If applicable, please mention how you meet these O-1 criteria in your application.
