About The Position

Kustomer is hiring an impactful Developer Experience Engineer to join our Foundation team. In this role, you will improve developer experience across the engineering organization by identifying friction points, modernizing tools, and enabling engineers to work faster and more effectively. This is a founding engineer role; the first of its kind at Kustomer. There’s no playbook yet; you’ll build this function from the ground up. You will build and evolve systems, workflows, and AI-powered tooling that engineers rely on day-to-day, focusing on impact rather than isolated internal tools. In this role, you will accelerate product delivery, formalizing backlog improvements, and helping Kustomer engineers 10x their efficiency.

AI is a core part of how we build. You'll use AI tools daily to move faster and raise the bar on what you ship. You'll also help build AI-powered product capabilities that meaningfully improve the customer experience.
We're looking for engineers with strong technical judgment, a high bar for craft, and real curiosity about how systems, product, and AI intersect. You take initiative, thrive in ambiguous problem spaces, and own your work end to end, from design through production. Not because someone's tracking it, but because you genuinely care about what you're building. If you want your work to directly shape the product and the team around you, we'd love to hear from you.
