Evaluate & integrate new tech: Rapidly prototype with third-party APIs, databases, model-serving platforms, and infra vendors to accelerate customer value.

Mentor & lead: Provide technical leadership for (and — if you’re up for it — manage) engineers across domains—pairing, reviewing, and unblocking as you go.
