About The Position

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. This role requires 5 days/week in our Boston office.

Requirements

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.
You deeply empathize with engineers and have experience making their workflows easier, faster, and safer.
You understand the transformative potential of AI in software development and can separate hype from practical value.
You are fluent in measuring success via engineering productivity, quality, and reliability metrics (e.g., PR throughput, CFR, incident rates, DevEx indices).
You can partner with senior engineering leaders (Infra, SRE, QE, product teams) and influence without authority.
You thrive in fast-moving environments, balance short-term wins with long-term strategy, and bias toward automation and self-service.

Responsibilities

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.
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.
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.
Drive success metrics such as PR throughput, cycle time, change failure rate, developer experience index, and AI tool adoption.
Partner with SRE and QE to ensure reliability and safety are built into every paved path — incidents and defects decrease even as velocity increases.
Guide architecture and tooling choices that will keep Klaviyo’s developer experience sustainable and scalable for years to come.
Establish instrumentation, run surveys, and analyze metrics to continuously validate impact and adjust based on outcomes, not assumptions.
Create transparency and open feedback loops with engineers, EMs, and leadership to ensure alignment and adoption of developer tooling and practices.
