The Amplify team builds the internal platforms, automation, and AI-driven systems that power how Klaviyos work every day. As an Engineering Manager, you will:
- Lead one or more engineering teams and help shape the technical direction for internal tools and platforms that improve efficiency, automation, and productivity.
- Lead a portfolio of internal systems supporting Sales, Marketing, Customer Service & Success, R&D, and Finance, including AI-powered workflows, internal web applications, data and event pipelines, third-party integrations, and support tooling.

- You are an effective cross-functional communicator, able to work closely with product, design, and business partners to align priorities and move work forward.
- You are a people-first leader who enjoys hiring, onboarding, mentoring, and developing engineers, creating an environment where individuals and teams can grow and do their best work.
- You enjoy leading teams that build internal platforms, tools, or systems that improve productivity, automation, and operational efficiency across an organisation.

Nice to have:
- Experience building internal tools, platforms, or automation for developers and/or non-technical teams.
