Join Flix's People & Organization Digital Transformation team as Senior HR Tech Solution Architect, reporting to the Head of Digital Transformation. You will shape and transform Flix's global HR technology landscape across a complex, multi-entity, multi-country organization. Key Responsibilities: - Work closely with FlixTech to shape Flix's target HR technology architecture across core HRIS, payroll, time & attendance, talent, recruiting, document management and surrounding enterprise systems. Ensure the architecture enables HR target operating and service-delivery models by connecting processes, roles, systems and service tiers while balancing global standards with local requirements. - Drive global HRIS transformation initiatives, from major platform revamps and redesigns to potential HRIS migrations. Evaluate technology options, build business cases, structure programs through project plans and RAID/risk frameworks, and drive execution through solution design, integrations, testing, cutover, parallel runs and stabilization. - Define HR technology integrations and data flows between the HRIS and surrounding enterprise systems. Determine what data moves between systems and through which integration patterns, including REST APIs, OAuth 2.0, webhooks, SFTP, middleware and event-driven architectures. - Establish and evolve HR technology governance and control frameworks, including system ownership and RACI, security and role-model design, least privilege and segregation of duties, audit trails, change/release governance, internal controls and data privacy aligned with GDPR and audit/IPO-readiness expectations. - Act as the bridge between HR functional and technology teams, translating business and process requirements into target-state solutions and executable designs. Drive global HR technology implementation projects from requirements through go-live. - Work closely with AI & Automation Engineers and HR Tech Business Analysts to set technical and architectural direction. The role is based in Berlin with global scope; regular collaboration with colleagues across European, APAC and US time zones is required. Requirements: - 8+ years of experience in HR technology transformation, HRIS, solution architecture, enterprise architecture or HRIS delivery, with a degree in Information Systems, Computer Science, Business Technology or a related field. - Strong HR domain and Workday expertise, with an understanding of how core HRIS, payroll, time & attendance, talent, recruiting and surrounding enterprise systems work together across a global HR technology landscape. Workday certifications are advantageous. - Demonstrable experience driving Workday transformations, including major Workday redesigns, platform revamps and/or migrations end to end. Hands-on enterprise Workday experience across configuration, integration or migration is a strong differentiator. - Strong integration and systems architecture knowledge, including REST APIs, OAuth 2.0, webhooks, SFTP, middleware, data flows and event-driven architectures across complex enterprise environments. - Experience supporting the design of HR target operating models, HR service-delivery models and technology governance frameworks, including security and role models, segregation of duties, audit trails, internal controls and data privacy in regulated, multi-country environments. - Experience with cloud architecture and AI & automation technologies is critical, including areas such as Claude/GenAI deployment, MCPs, n8n and Rovo Agents, alongside strong Jira project-management capabilities. - Fluency in English. Certifications in solution/enterprise architecture, project management, agile or automation (e.g. TOGAF, PMP, SAFe, Scrum, Six Sigma, n8n) are a plus.
