The posting

Job description

Our databases power order management, market data, clearing and settlement, risk controls, and customer asset systems — with high demands on availability, data consistency, and multi-jurisdiction compliance.We are looking for a DBA to join our Singapore team and take ownership of the operations and build-out of the data layer of our multi-region SaaS clusters, with plenty of room to grow into financial-grade data architecture and multi-market compliance practices.

What You Will Do

1. Operate the databases of our multi-region (US/SG/JP) SaaS clusters day to day: deployment, upgrades, backup and recovery, monitoring and alerting, and incident handling — mainly PostgreSQL, MySQL, Redis, plus analytics engines such as ClickHouse. 2. Help design and deliver our multi-tenant SaaS data solutions: tenant isolation (dedicated instance / database / schema), automated tenant onboarding (provisioning, password rotation), and per-tenant backup and recovery. 3. Own multi-AZ high availability and DR drills within each region, meeting RPO/RTO targets for core systems. 4. Run capacity planning and performance tuning: slow-query governance, indexing and execution plans, connection pooling; participate in P0/P1 incident response and post-mortems. 5. Use and improve our database platform tooling (Terraform, Bytebase, self-service query tools) to make launching a new market or onboarding a new tenant increasingly automated. 6. Review schema designs and SQL with engineering teams, gate production changes, and share on-call duties with SRE.

What We Are Looking For

1. 3+ years of production DBA experience with PostgreSQL and/or MySQL, including independently handling live incidents. 2. Hands-on experience with mainstream HA and backup/recovery solutions (e.g., replication, Patroni, MHA, or Redis Sentinel), including real failover or recovery drills. 3. Solid performance tuning skills: slow-query analysis, index design, reading execution plans, diagnosing locking and connection-pool issues. 4. Working experience with AWS RDS/Aurora (or equivalent cloud databases), including Multi-AZ deployment and cloud backup/recovery patterns. 5. Working English: able to read and write documentation and join meetings in English; Mandarin is a plus.

Nice to Have 1. Financial industry experience — database operations at a broker, exchange, payments, or banking system; familiarity with order, market-data, or settlement data models is a bonus. 2. SaaS / multi-tenancy — involvement in designing or operating multi-tenant data platforms. 3. Larger-scale experience — systems with 100k+ QPS or TB+ data volumes. 4.Database internals — deep understanding of MVCC, transaction isolation, and replication; able to analyze issues at the protocol or source-code level. 5. Engineering skills — Python/Go/Shell scripting for ops tooling; Kubernetes experience. 6. Time-series / analytics — production experience with ClickHouse or TimescaleDB.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
