About the Team

The Amplify Engineering team builds systems of efficiency and automation around the processes and problems of our fellow Klaviyos. We create tools that help Klaviyos move faster and operate at scale, with direct visibility into how our work drives measurable impact across the organization.

This role is for builders, leaders, organizers, and problem solvers. Our solutions use state-of-the-art technologies and are regularly demoed for Klaviyo’s senior leadership. It’s an opportunity to design and build systems that shape how thousands of Klaviyos work every day — with fast iteration, high autonomy, and clear, visible results.

How You’ll Make an Impact

As the Engineering Manager for the Amplify Engineering team, you will:

• Lead a team of seven engineers with potential to grow the team further.

• Own the vision and oversee the implementation of the Klaviyo Demo Studio (KDS) — a homegrown product used by our Sales organization to demonstrate Klaviyo’s value to prospective customers.

• Manage a portfolio of internal tools that serve Klaviyo’s Sales and R&D organizations, driving efficiency and productivity through automation.

• Balance hands-on technical involvement with people leadership — leading through others, setting direction, and modeling best practices.

• Collaborate with Product, Design, and senior stakeholders to translate organizational challenges into high-quality software solutions.

• Foster a culture of innovation, curiosity, and technical excellence within the team.

Who You Are

• 6–8+ years of software engineering experience, including 3–5+ years managing high-performing teams in a fast-paced SaaS environment.

• Skilled at leading teams that build internal platforms, tools, or systems for automation and efficiency.

• Strong communicator who can align stakeholders, manage competing priorities, and drive consensus across teams.

• A natural mentor and coach who develops engineers through constructive feedback and opportunities for growth.

• Comfortable navigating ambiguity and driving clarity — you set direction even when the path isn’t fully defined.

• Excited to experiment with AI tools to boost team productivity and innovation.
