Job description

About the Role

We are building a next-generation HRIS platform that tightly integrates attendance, overtime, reimbursement, and payroll into a seamless, reliable experience for our clients.

We're looking for backend engineers who are obsessed with data consistency, system resilience, and clean architecture — and who thrive working on transaction-heavy, critical systems.

Responsibilities

• Design, build, and maintain backend services that sync attendance, overtime, reimbursement, and payroll.
• Ensure high data integrity and system consistency, even under concurrent user updates.
• Optimize and scale relational databases (PostgreSQL preferred).
• Design clear, extensible APIs to support frontend and third-party integrations.
• Implement event-driven architecture to handle system-wide updates efficiently.
• Monitor and improve system reliability, latency, and error rates.
• Collaborate with product and engineering teams to build a scalable HRIS platform.

Why Join Us?

• Opportunity to build a core system from early stages with massive impact.
• Lean, fast-moving, high-ownership culture.
• Solve real-world problems for growing businesses.

• 3–7 years experience in backend development.
• Experience in Golang.
• Strong experience with PostgreSQL (or other RDBMS) and database optimization.
• Solid knowledge of transaction management, data modeling, and eventual consistency concepts.
• Hands-on experience building RESTful APIs or GraphQL APIs.
• Familiarity with distributed systems, message queues (e.g., Kafka, RabbitMQ), and caching (e.g., Redis).
• Experience in cloud infrastructure (AWS, GCP) is a big plus.
• Bonus: Experience in financial systems, payroll, HR tech, or ERP platforms.
