Hands-on experience with mainstream HA and backup/recovery solutions (e.g., replication, Patroni, MHA, or Redis Sentinel), including real failover or recovery drills.\n3. Solid performance tuning skills: slow-query analysis, index design, reading execution plans, diagnosing locking and connection-pool issues.\n4. Working experience with AWS RDS/Aurora (or equivalent cloud databases), including Multi-AZ deployment and cloud backup/recovery patterns.\n5. Working English: able to read and write documentation and join meetings in English; Mandarin is a plus.\nNice to Have\n1. 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.\n2. SaaS / multi-tenancy - involvement in designing or operating multi-tenant data platforms.\n3. Larger-scale experience - systems with 100k+ QPS or TB+ data volumes.\n4.Database internals - deep understanding of MVCC, transaction isolation, and replication; able to analyze issues at the protocol or source-code level.\n5. Engineering skills - Python/Go/Shell scripting for ops tooling; Kubernetes experience.\n6. Time-series / analytics - production experience with ClickHouse or TimescaleDB.\nWhat You Will Do\n1. 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.\n3. Own multi-AZ high availability and DR drills within each region, meeting RPO/RTO targets for core systems.\n4. Run capacity planning and performance tuning: slow-query governance, indexing and execution plans, connection pooling; participate in P0/P1 incident response and post-mortems.\n5. 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.\n6. Review schema designs and SQL with engineering teams, gate production changes, and share on-call duties with SRE.","description_format":"text","description_chars":2931,"description_truncated":false,"requirements":{"experience_years_min":3,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Software","Artificial Intelligence","Financial Services","Central Banks & Financial Regulators"],"lifecycle":[{"event":"open","at":"2026-10-21T13:06:43Z"}],"visa":[],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":1,"age_days":9,"expected_fill_days":75,"reasons":["conf:2","velocity","win:early"],"computed_at":"2026-10-31T05:58:55Z"},"pay":null,"html_url":"https://alion.io/job/longbridge-database-administrator-saas-infrastructure-sg","json_url":"https://alion.io/job/longbridge-database-administrator-saas-infrastructure-sg.json","meta":{"generated_at":"2026-11-01T00:07:35Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":237,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-02T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":1045843},"rest":"https://alion.io/mcp/rest/get_company?id=1045843"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Flongbridge-database-administrator-saas-infrastructure-sg"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Flongbridge-database-administrator-saas-infrastructure-sg"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Flongbridge-database-administrator-saas-infrastructure-sg"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/longbridge-database-administrator-saas-infrastructure-sg\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Flongbridge-database-administrator-saas-infrastructure-sg"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3004016}},{"tool":"search_jobs","arguments":{"company":"longbridge.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3004016},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
