[Hiring] Workday Integration Engineer @Flix

Role Description

We are looking for an experienced Integration Engineer to join Flix on a freelance/service agreement basis (B2B contract). This is a contractor engagement for a seasoned integration professional who wants to work on impactful, hands-on engineering challenges.

• Design, build, and maintain AWS-based integrations between our Workday HRIS and the internal and external systems within FlixTech People Enablement Stream.
• Work closely with HR, IT Infrastructure, various internal stakeholders, and external vendors to ensure seamless data flow and automation across platforms.

About the Engagement

• Design, build, and deploy scalable integrations on AWS connecting HR, payroll, and workforce platforms — consuming data from systems like Workday, Deel, Greenhouse, and other third-party providers.
• Architect and maintain event-driven and API-based integration workflows using AWS services including EventBridge, Lambda, API Gateway, ECS/Kubernetes, SQS, and S3.
• Use Python to develop integration services, automation scripts, and data transformation and mapping logic to ensure accurate and consistent data exchange between systems.
• Use Infrastructure as Code, such as Terraform, to provision and maintain cloud infrastructure in a consistent and repeatable manner.
• Implement CI/CD pipelines using Git and DevOps tools to streamline code versioning, testing, and deployment.
• Implement secure integration pipelines using OAuth 2.0, SFTP, certificate-based authentication, AWS KMS encryption, fine-grained access controls, and PII masking to ensure GDPR compliance and protect international employee data.
• Implement monitoring, logging, and error-handling mechanisms to support troubleshooting, data integrity, and reliable production operations.
• Collaborate with functional teams to understand business processes and translate them into robust integration solutions.
• Troubleshoot and optimize integration performance in development, testing, and production environments.
• Provide technical guidance, best practices, and consulting to other developers.

Qualifications

• Experience connecting diverse HR, ATS, payroll, and EOR systems (Workday, Deel, Greenhouse, etc.), with a strong grasp of employee lifecycle events, organizational structures, and payroll cutoffs.
• Experience with API-based integrations using REST, SOAP, and JSON/XML.
• Experience with AWS, API Gateway, Terraform, and Infrastructure as Code.
• Familiarity with CI/CD pipelines, version control systems, and modern DevOps practices.
• Experience with secure data exchange, including SFTP, certificate management, encryption, and API authentication.
• Strong communication skills to collaborate with HR, Finance, IT, and external vendors to turn business needs into integration designs.
• Fluent in English; German language skills are a welcome bonus.

Preferred Skills

• Experience with Workday Integration technologies such as Workday Studio, PECI, Core Connectors, or EIBs.

Collaboration Model

• Cooperation based on a service agreement (B2B/freelance contract), not an employment contract.
• You will operate as an independent contractor, responsible for delivering agreed services and submitting invoices.
• Location: open for contractors based in Poland.
