· Develop, optimise, and troubleshoot OLAP-related queries.

· Support feature teams with developing and maintaining the database.

· Diagnose and resolve issues involving locking, contention, inefficient joins, and indexing gaps.

· Recommend and implement indexing, partitioning, or structural improvements.

· Participate in load testing and capacity discussions related to the data layer.

· Participate in design and peer reviews.

· Mentor team members on SQL best practices, schema design, and performance techniques.

· Work within a small agile team to deliver high-quality features and continuously improve engineering practices.

· Document data structures, conventions, and patterns for broader engineering use.

Required Skills and Experience

· 4–5 years of experience in database engineering, SQL development, or backend engineering with strong data responsibilities.

· Deep expertise in MS-SQL:

o Complex joins

o Execution plan analysis

o Query optimisation

o Indexing strategy

· Experience building ETL/ELT components.

· Strong understanding of relational data modelling and schema design principles.

· Experience improving database performance through structural and query-level optimisations.

· Fully remote from anywhere within the Philippines.

· Must have at least 6 hours of daily overlap with the Australian Eastern Time Zone (AEST/AEDT).

· Flexible working hours outside the overlap period.
