Lead Product Manager, Developer Experience

Klaviyo is on a mission to build a world-class, AI-first engineering organization. To do this, we're looking for a Lead Product Manager of Developer Experience who will craft and drive the vision for our internal development environment. In this role, you'll treat developers as your customers - making their daily workflows faster, safer, and more joyful. Your work will directly impact how quickly and confidently Klaviyo engineers can build, test, and release high-quality products.

In this role, you'll partner deeply with Engineering leaders across Developer Infra, SRE, and product teams to shape how Klaviyo develops software. Your focus will be on outcomes: enabling faster cycle times, reducing incidents, leveraging AI to automate toil, and making Klaviyo a magnet for top engineering talent. Please note this is a hybrid role and requires 3 days/week in our Boston office. Fully remote candidates will not be considered at this time.

What You'll Do:

• Set the Vision: Define the product strategy for Klaviyo's developer environment, aligning to our Need for Speed program - targeting massive improvements in engineering velocity, developer experience, and quality.
• Make Developers Your Customers: Treat Klaviyo engineers as the primary stakeholders. Identify pain points across the PDLC (coding, testing, deployment, maintenance) and prioritize investments that meaningfully improve their productivity and happiness.
• Accelerate with AI: Institutionalize AI as a force multiplier - from autonomous code agents to AI copilots for reviews and testing. Ensure Klaviyo leads in adopting AI-first development practices, reducing friction without compromising safety.
• Deliver Measurable Outcomes: Drive success metrics such as PR throughput, cycle time, change failure rate, developer experience index, and AI tool adoption.
• Champion Quality & Safety: Partner with SRE and QE to ensure reliability and safety are built into every paved path - incidents and defects decrease even as velocity increases.
• Scale for the Future: Guide architecture and tooling choices that will keep Klaviyo's developer experience sustainable and scalable for years to come.
• Be Data-Driven: Establish instrumentation, run surveys, and analyze metrics to continuously validate impact and adjust based on outcomes, not assumptions.
• Build for Collaboration: Create transparency and open feedback loops with engineers, EMs, and leadership to ensure alignment and adoption of developer tooling and practices.

Who You Are:

• Strategic Builder: You're an Engineering leader turned Product think or Founder. Or you've led product for developer platforms, infrastructure, or tools, with a track record of improving engineering velocity and reliability.
• Developer-Centric Thinker: You deeply empathize with engineers and have experience making their workflows easier, faster, and safer.
• AI-Forward Mindset: You understand the transformative potential of AI in software development and can separate hype from practical value.
• Metrics-Oriented: You are fluent in measuring success via engineering productivity, quality, and reliability metrics (e.g., PR throughput, CFR, incident rates, DevEx indices).
• Influential Collaborator: You can partner with senior engineering leaders (Infra, SRE, QE, product teams) and influence without authority.
• Bias for Action: You thrive in fast-moving environments, balance short-term wins with long-term strategy, and bias toward automation and self-service.

Success in This Role Looks Like:

• Klaviyo engineers feel they can deliver faster, safer, and with higher confidence than ever before.
• AI tools are seamlessly integrated into workflows, with widespread adoption and measurable productivity gains.
• Development cycle times shrink, while incidents, defect escapes, and change failure rates decrease.
• Developers rank Klaviyo's internal tooling and environment as best-in-class, making it a competitive advantage in attracting and retaining talent.
• The Dev Infra & SRE product strategy is clear, measurable, and directly tied to Klaviyo's ability to deliver customer value quickly and reliably.
