Adyen is seeking a People Technology Application Engineer to join the Build HR Technology & Analytics team in Amsterdam. This role sits at the intersection of product engineering and HR operations, leading the application and integration engineering layer for Adyen's global People organization.
You will design, build, and maintain custom applications, API middleware, automated workflows, and system-to-system integrations across the Workday ecosystem and enterprise tools. Key responsibilities include:
• Engineer application & integration solutions: Design and develop custom applications, programmatic API integrations, webhooks, and middleware connecting Workday HCM with Greenhouse, Qualtrics, Docebo, Slack, and internal platforms.
• Extend platform capabilities: Build custom app extensions and tailored UI/UX workflows using Workday Extend, Python frameworks, and modern low-code/no-code platforms.
• Automate operational friction: Follow a "simplify first, then automate" philosophy to eliminate manual processes and technical debt. Research, prototype, and deploy automated workflows and custom AI agents (e.g., Google Vertex AI / Gemini Enterprise). Stay curious about emerging technologies and know when they add genuine business value.
• Design for security, privacy, and governance: Embed strict access controls, data security, and GDPR compliance into all software architectures. Treat security, privacy, and system governance as fundamental engineering requirements.
• Set engineering standards & documentation: Establish clear software engineering practices, API specifications, and maintainable technical documentation to enable easy support and scaling.
• Partner across Product & Engineering: Collaborate with Core People Tech specialists, Data Engineers, Security, and HR functional leads to translate complex business needs into clean technical solutions. Balance speed with long-term code maintainability.
Success looks like: Workday and the broader SaaS ecosystem connected through reliable, maintainable API integrations; repetitive manual tasks systematically eliminated through clean Python automation; reusable application foundations and middleware enabling faster feature development; and security/privacy seamlessly embedded in every deployed application.
