Lead Software Engineer - Commerce Platform

Who We Are

Healthcare needs a better rhythm: one that keeps care continuous and deeply human. Heidi is building an AI Care Partner that works alongside clinicians to make that possible.

We’re a team of doctors, engineers, designers, researchers, and creatives building tools that help clinicians stay focused on what matters most: their patients.

In just 18 months, Heidi has given back more than 18 million hours to healthcare professionals — supporting 73 million patient visits in 116 countries. Today, more than two million patient visits each week are powered by Heidi worldwide.

Backed by nearly $100 million in funding, we’re growing in the US, UK, Canada, and Europe, partnering with leading health systems including the NHS, Beth Israel Lahey Health, and Monash Health.

Your team

You'll lead the small team powering how Heidi grows. Your work shapes the architecture of our billing, payments, and entitlements platform: how the pieces fit together so customers can seamlessly access the products they need. Near-term that means launching usage-based billing, building seat management, and scaling our Stripe integration into global markets. You'll do it with a small group of strong engineers and the latest agentic tooling at your fingertips, where every feature shipped removes friction for customers and fuels the revenue that drives Heidi forward.

What you’ll do

• Lead a small, focused team building Heidi's billing, payments, subscriptions, and entitlements systems; the engine behind how we monetise and scale

• Stay hands-on in the code: ship features, review architecture, and set the technical bar

• Own delivery end-to-end for your team's roadmap, balancing velocity with reliability and operational rigour

• Coach the engineers working with you. Run effective 1:1s on craft and project execution, unblock them, and raise the standard of the work

• Partner with Product, Design, Finance, and Go-to-Market to turn revenue goals into shipped features

• Shape how we run: hiring, onboarding, team rituals, on-call, and engineering practices as the team grows

What we’re looking for

• 6+ years of software engineering experience, with time spent as a tech lead or senior engineer accountable for a team's output

• Strong technical foundation across the stack. Comfortable in Python and TypeScript/React, or eager to pick them up quickly

• Track record of shipping commerce or billing systems in production: subscription plans, seat management, entitlements, pricing changes, or similar

• Clear communicator with strong product mindset who translates business needs into technical priorities and keeps stakeholders aligned

• Comfort with ambiguity. This is a new team in a fast-moving company; you'll help define the playbook

• Motivated by ownership and impact. You want to build something meaningful, not manage process

Valuable experience

• Stripe API at depth: Billing, Connect, webhooks, idempotency, reconciliation

• Usage-based billing: metering, rating, proration, invoice accuracy at scale

• Event-driven architecture or data pipelines for collecting usage metrics efficiently across a platform

• Integrations across the CRM, billing, and accounting stack (Salesforce, HubSpot, NetSuite, Xero, etc.)

• Designing for global payments: multi-currency, tax, and regional payment methods

• Using AI development workflows to ship faster without compromising quality

The way we work

1. Build to Last

We design for safety and reliability so clinicians, patients, and our teams can trust what we build every day.

4. Make Others Better

Honest feedback, steady support, and shared growth keep our teams improving together.
