- 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
About You
- 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

Preferred Skills:
- Experience with Workday Integration technologies such as Workday Studio, PECI, Core Connectors, or EIBs
Collaboration Model
