This role requires expertise in API development, system interoperability, data transformation, and automation to streamline payroll processes and enhance customer experience. The SID collaborates with internal teams and external partners to ensure efficient, reliable, and secure integrations aligned with business objectives and compliance requirements.

Duties and responsibilities:

Development of integration solutions

• Design and develop secure, scalable integration solutions to connect payroll systems with HCM, WFM, ERP, and accounting platforms.
• Work with various file formats (e.g., JSON, XML, CSV, EDI) and communication protocols (e.g., REST, SOAP, SFTP, Webhooks) to build robust integration interfaces.
• Develop and maintain API connectors for third-party platforms to facilitate automated data synchronization (e.g., employee records, payroll data, time tracking, and tax compliance).
• Ensure integrations comply with industry standards such as OAuth 2.0, SAML, and secure data transfer protocols.

Error monitoring and enhancements

• Monitor integration performance, troubleshoot issues, and optimize existing payroll-related integrations for efficiency and reliability.
• Enhance error-handling mechanisms to ensure accurate and timely payroll processing while minimizing disruptions.
• Work closely with compliance teams to ensure integrations align with regulatory requirements such as SOC 2, GDPR, and tax reporting guidelines.
• Implement data validation and auditing mechanisms to ensure accuracy in payroll processing.

Preparation of technical documentation

• Create and maintain comprehensive technical documentation for integration processes, data workflows, and troubleshooting guides.
• Provide internal training and knowledge sharing sessions to help teams understand integration frameworks and API usage.

Cross-team collaboration and support

• Work closely with product managers, payroll specialists, and implementation teams to ensure integration solutions align with customer needs.
• Collaborate with external partners and vendors to establish seamless bi-directional integrations between payroll software and third-party applications.
• Provide technical support and troubleshooting assistance for clients facing integration challenges.

Education and experience:

• 5+ years of experience in software development, with a strong focus on system integrations in a payroll, HR, or financial software environment.
• Proficiency in Java/Kotlin for developing robust and scalable integration solutions.
• Strong experience in RESTful API development, data transformation, and integration workflows.
• Knowledge of OAuth 2.0, OpenID, and SAML authentication for secure integrations.
• Familiarity with database structures (SQL, NoSQL) and cloud-based integration platforms.
• Understanding of Agile methodologies, test-driven development, and CI/CD pipelines.
• Strong analytical skills for debugging complex systems and ensuring data integrity in payroll transactions.
• Excellent verbal and written communication skills in English for documentation and stakeholder collaboration.
• Ability to prioritize multiple tasks and work in a fast-paced environment.

SMART Performance Goals:

High-Quality & Reliable Integrations

• Reduce rework: Fewer than 10% of assigned integration tasks should be reopened more than twice due to defects or missing requirements.
• Error-free releases: At least 95% of integration deployments should pass automated and manual QA validation on the first attempt before going live.
• Uptime and stability: Ensure integrations maintain at least 99.9% uptime, with documented resolution time for critical issues under 4 hours.

Efficient Time Management

• Time tracking accuracy: Ensure at least 90% of work time is logged weekly in YouTrack, with task descriptions clearly detailing the work performed.
• Task completion rate: Complete at least 85% of assigned integration tasks within the planned sprint cycle.

Accurate Development Estimations

• Estimation accuracy: At least 70% of tasks should be completed within ±4 hours of the original time estimate.
• Time spent vs. estimated time: The average variance between estimated and actual development time should be less than 20% over a rolling three-month period.

Industry Compliance & Best Practices

• Compliance adherence: Ensure 100% of payroll integrations meet regulatory requirements (SOC 2, GDPR, tax compliance) as validated by compliance audits.
• Best practice adoption: Conduct at least two training sessions per quarter on industry best practices and integration security.
• Documentation upkeep: Update and maintain technical documentation for 100% of completed integration features, ensuring clarity and accessibility.

Diverse Contributions to Payroll Integrations

• Balanced workload distribution: Contribute to at least three of the following areas each quarter:
• New feature development (API integrations, system connectors, automation).
• Test automation (unit, integration, regression testing).
• Documentation updates (troubleshooting guides, API specs).
• New task creation and backlog grooming.
• Peer code reviews (participate in at least 10 merge request reviews per quarter).
