Senior Engineer, Machine Learning

As a Senior Engineer, Machine Learning on Virta's Applied AI team, you build the models that shape how Virta shows up for each member: who needs a coach's attention this week, which nudge will land, what moves someone closer to reversing their disease. You take a fuzzy clinical or operational question, sharpen it into something a model can actually answer, and carry it the whole way to production.

You are hard to fool. A number that looks good on a slide doesn't convince you until you've checked what's underneath it: whether a leak inflated it, or whether it's quietly wrong for a segment it doesn't call out. You start simple, prove the baseline honestly, and add complexity only once it earns its place.

Your models don't just ship, they stay healthy without you babysitting them. As Applied AI moves from linear to exponential, you build models on Virta's deep, longitudinal member data and put them on the ML platform that retrains them, watches their quality, and pulls you in only when something is genuinely wrong. What one engineer can deliver stops being capped by how many models they can keep alive.
