Ruby Labs is a leading tech company that creates and operates innovative consumer products across health, education, and entertainment industries. We are building a high-scale payment orchestration system that processes millions of financial transactions every month. As our transaction volume and customer base grow, our database layer has become critical to our success.

The Role

We are looking for a strong Database Engineer to own, scale, and evolve our data infrastructure, ensuring it remains fast, reliable, and ready for long-term growth. You will be responsible for designing, operating, and optimizing databases in a high-volume payments environment, working with large datasets, complex queries, performance bottlenecks, and analytics pipelines.

Responsibilities

• Own and operate AWS Aurora (PostgreSQL) in a high-load production environment.
• Design and evolve schemas for large transactional domains (payments, customers, subscriptions, events).
• Implement and maintain table partitioning strategies, advanced indexing, query optimization, and execution-plan tuning.
• Analyze and optimize slow queries and production metrics.
• Design high-performance search solutions for large operational datasets used in internal CRM tools.
• Work with event and log data pipelines, enabling fast, real-time insights for product, finance, and operations teams.
• Ensure data integrity and consistency in financial workflows.
• Define and monitor database health metrics and plan safe schema changes and migrations.

Requirements

• Strong hands-on experience with PostgreSQL in production.
• Experience managing large databases (hundreds of millions of rows or more).
• Solid understanding of indexing strategies, query planners, transactions, isolation levels, and locking.
• Experience working with AWS-based infrastructure, ideally AWS Aurora.
• Ability to independently investigate and resolve complex performance issues.

Nice to Have

• Experience in payments, billing, fintech, or financial systems.
• Familiarity with analytical databases (ClickHouse, Tinybird, or similar).
• Understanding of event-driven architectures and data pipelines.
• AWS certifications (e.g., Solutions Architect, Database Specialty).

What We Offer

• Remote Work Environment: Work from anywhere, promoting a healthy work-life balance.
• Unlimited PTO: Enjoy unlimited paid time off to recharge.
• Paid National Holidays: Relax on national holidays with paid time off.
