Steve Ambielli

I build engineering teams that carry mission-critical systems — and the people who run them.

Twenty years in software, the last five leading global engineering organizations in healthcare. I've taken platforms through modernization, identity, and AI, and grown engineers into leads and managers along the way. I care about systems that stay up and teams that stay whole.

Portrait of Steve Ambielli

Engineering leadership is mostly clarity, repeated patiently.

I started as a developer at an agency, building for Pfizer, Janssen, Novartis and IEEE, and spent fourteen years learning how to ship under real constraints. A stint at Darden put me on high-volume consumer software. Since 2021 I've been at Zelis, where healthcare claims move at a scale that makes every decision about reliability a decision about people.

Today I own engineering strategy, delivery and operational excellence for three global teams... architecture, roadmap, on-call, career growth. I founded Zelis' first design language system because consistency compounds, and I now lead the AI and OCR platform work reshaping how claims get reviewed.

What I look for next: an organization where platform, AI and people strategy sit in the same room, and where someone has to be accountable for all three.

03 — How I lead

i.

Stability is a feature

Monitoring, release discipline and incident practice come before velocity. Teams move fastest when they trust production.

ii.

Standards beat heroics

Shared systems (design, API, identity) turn individual effort into organizational speed that survives reorgs and turnover.

iii.

Grow the bench

The clearest measure of a manager is how many people left the team more capable than they arrived. I plan for that on purpose.

iv.

AI where it earns its place

In regulated domains, models are only useful inside a workflow people trust. Start with the operator, then the model.
