About Kustomer

Kustomer is the industry leading conversational CRM platform perfecting every customer experience. Built with intelligent tools such as AI and Automation, no code-configuration and a connected data platform that unifies data from multiple sources through a single timeline, Kustomer empowers businesses to operate with greater efficiency and deliver more personalized service to customers across any channel, making every interaction more meaningful and memorable.

Today, Kustomer is the core platform for some of the leading customer service brands like Sweetgreen, Starz, Vuori, Resy and Cotopaxi.

Kustomer was founded in 2015 by serial entrepreneurs Brad Birnbaum and Jeremy Suriel and has raised over $230M in funding backed by leading VCs. Meta announced its intention to acquire Kustomer in 2020 and completed the transaction in 2022. Kustomer joined Meta’s Business Messaging Group to transform the way people and businesses communicate through modern messaging channels. In 2023, Kustomer spun out from Meta as a standalone company backed by original partners, Battery, Redpoint and Boldstart Ventures, who have invested $60M.

In 2025, Kustomer announced a $30M Series B led by Norwest, with continued support from Battery, Redpoint, and Boldstart. This milestone reflects strong conviction in our vision and fuels our next chapter of growth: expanding our AI-native platform, accelerating product innovation, and scaling our exceptional team.

Our Krew is made up of passionate and collaborative people who really care about what they do and the people they help. We look for people who are passionate about enhancing the customer service experience for everyone involved, as it's the core of what we do. We're growing our business with no plans of slowing down. We actively seek individuals who want to learn and be challenged every day.

We have also transitioned to a remote friendly company, with Krew members located throughout the U.S. and U.K. coming together for Kamp Kustomer each year.

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 re’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.
