Adyen provides payments, data, and financial products in a single solution for customers like Meta, Uber, H&amp;M, and Microsoft - making us the financial technology platform of choice. At Adyen, everything we do is engineered for ambition.

For our teams, we create an environment with opportunities for our people to succeed, backed by the culture and support to ensure they are enabled to truly own their careers. We are motivated individuals who tackle unique technical challenges at scale and solve them as a team. Together, we deliver innovative and ethical solutions that help businesses achieve their ambitions faster.

Senior Product Manager - Developer Experience

The Internal Developer Platform (IDP) cluster is on a mission to create standardized, scalable, and delightful experiences across the software development life cycle (SDLC) so Adyen engineers are empowered to deliver value more efficiently and reliably for our customers.

As a Senior Product Manager within the IDP cluster, you will manage a key stream of our platform evolution. Your goal is to transition our engineering organization from fragmented, &quot;tribal knowledge&quot; based flows to a cohesive, automated ecosystem that reduces cognitive load, minimizes manual toil, and ensures our platform scales with our global engineering footprint. 2026 is our year of deep optimization and resilience; you are a product leader who understands that scaling a platform requires balancing innovation with mandatory reliability and stability mandates

What you'll do:
<ul>
<li>Optimize the SDLC: Drive initiatives to reduce SDLC friction, such as reducing CI flakiness and improving build insights, to help teams shift from centralized, manual processes to systemic, automated &quot;golden paths&quot;.</li>
<li>Drive Product Maturity: Take ownership of product lifecycle management by assessing the maturity of our toolset, executing on necessary deprecations, and ensuring our core products have clear adoption paths and value propositions.</li>
<li>Build Technical Context: Partner with IDP engineering to bridge the gap between generic AI models and Adyen's complex architecture. You will prioritize the rollout of AGENTS.md standards, internal RAG pipelines, and Model Context Protocol (MCP) servers for tools like GitLab and Jira.</li>
<li>Foster Developer Autonomy: Work across the organization to bridge the gap between infrastructure and developer needs, building &quot;LEGO-block&quot; style abstractions that allow teams to own their pipelines and release cycles while maintaining secure, compliant guardrails.</li>
<li>Validate ROI &amp; Manage Vendors: Implement data-driven feedback loops to track adoption and measure SDLC improvements against core metrics like DXI, Change Failure Rate, and developer velocity</li>
</ul>
Who you are:
<ul>
<li>10+ years of product experience ideally within Platform Engineering, Developer Experience (DevEx), or AI-enabled technical products.</li>
<li>You are technically credible. You can confidently spar with engineers about system architecture, CI/CD pipeline constraints, and the balance between centralized governance and team autonomy.</li>
<li>You are a master of change management. You know how to influence developer habits and drive adoption in highly opinionated technical environments.</li>
<li>You are data-driven, capable of translating subjective developer feedback and system/usage data into clear impact metrics.</li>
<li>You thrive in ambiguity. You can execute quickly without waiting for perfect information and adapt quickly to new information</li>
</ul>
Our Diversity, Equity and Inclusion commitments

Our unique approach is a product of our diverse perspectives. This diversity of backgrounds and cultures is essential in helping us maintain our momentum. Our business and technical challenges are unique, and we need as many different voices as possible to join us in solving them - voices like yours. No matter who you are or where you're from, we welcome you to be your true self at Adyen.

Studies show that women and members of underrepresented communities apply for jobs only if they meet 100% of the qualifications. Does this sound like you? If so, Adyen encourages you to reconsider and apply. We look forward to your application!

What's next?

Ensuring a smooth and enjoyable candidate experience is critical for us. We aim to get back to you regarding your application within 5 business days. Our interview process tends to take about 4 weeks to complete, but may fluctuate depending on the role. Learn more about our hiring process here.
