Vapi (/ˈwɑːpi/):
Why We’re Hiring This Role:
What You’ll Do:
30 Day:
Learn the Vapi platform, architecture, and codebase deeply enough to have real technical opinions.
Build relationships with your team. Understand each engineer's strengths, growth areas, motivations, and blockers.
Shadow the current workflow—standups, planning, code reviews, deploys. Identify what's working and what's slowing the team down.
Partner with product and design to understand the roadmap and priorities.
60 Day:
Own team health and delivery. Your team ships predictably, sustainably, and with quality.
Establish engineering rituals that create clarity: sprint planning, retros, 1:1s, blameless postmortems.
Start upgrading the team: identify gaps, open reqs, source candidates, raise the hiring bar.
Remove at least one systemic blocker that's been killing velocity (process, tech debt, unclear ownership).
90 Day:
Your team is humming: engineers are growing, shipping weekly, and fire drills are rare.
You've made at least one exceptional hire (or have strong candidates in pipeline).
Delivery is predictable. Product and leadership trust your team's estimates and commitments.
You're raising the engineering bar at Vapi—through code review culture, mentorship, and setting the example for what great engineering leadership looks like.
