全职 Senior Database Administrator -Singapore 工作, 薪水, ONERWAY 公司招聘中 - Ricebowl

Onerway is hiring a Singapore-based Senior Database Administrator to own the availability, performance and security of the databases behind a PCI DSS certified cross-border payments platform.

About the role

Onerway operates in Singapore, the UK, Hong Kong and Europe, with engineering teams in Shanghai and Wuhan and a new technology team being built in Singapore. Payment data is our most sensitive asset, and the database tier sits on the critical path of every transaction.

You will be the hands-on database authority for the group on Azure and AWS: you design, tune and protect MySQL and PostgreSQL estates, set the standards that engineering teams follow, and step in when production needs you. You will work daily with developers and SRE colleagues in Singapore, Shanghai and Wuhan.

Key responsibilities

• Install, configure, tune and maintain MySQL and PostgreSQL services across production and non-production environments on Azure and AWS.
• Review database designs and SQL in project work, and propose optimisations based on business logic and measured database performance.
• Define database standards and policies, train engineering teams on them, and make sure they are applied in practice.
• Own backup and restore, disaster recovery, capacity planning, monitoring and alerting, performance tuning and incident response for the database tier.
• Design and implement database solutions for security, high concurrency, high availability, scalability and elasticity.
• Support PCI DSS and regulatory evidence for the database layer, including access control, encryption, audit logging and data retention across the jurisdictions we operate in.

Requirements

• Bachelor's degree or above in computer science or a related field, with 5+ years of MySQL database operations experience.
• Working knowledge of managed database services on Azure and AWS.
• Deep understanding of MySQL or PostgreSQL architecture and internals, and sound judgement on database selection and data modelling for a given scenario.
• Strong command of high-availability architecture, primary-replica replication, and sharding.
• Proven performance tuning skills, able to trace bottlenecks across the full path (network, CPU, I/O, operating system) and resolve faults quickly.
• Fluent with Shell and Python for automation of routine work.
• Fluent English and Mandarin, as you will work directly with the China-based engineering teams.
• Accountable, honest and steady, a fast learner, and a good communicator and team player.

Nice to have

• Familiarity with financial data compliance requirements in the US, UK, EU, Singapore and Hong Kong.
• Experience running databases in a PCI DSS or other regulated payments environment.
• Experience with MAS TRM-aligned database controls, such as privileged access management, encryption and audit trails.
