Supabase is a Postgres development platform providing a complete backend solution including Database, Auth, Storage, Edge Functions, Realtime, and Vector Search. We're seeking an experienced Database Support Engineer fluent in Japanese to join our Support Team and help developers resolve complex technical issues.
In this role, you'll investigate and resolve advanced customer issues across Postgres, Auth, RLS, Storage, Realtime, Edge Functions, and client libraries. You'll provide consultative, proactive advice to optimize workloads and help advanced users avoid common pitfalls. You'll reproduce bugs, isolate root causes, propose workarounds, and escalate to engineering with solid repro steps. You'll ask targeted questions that turn incomplete reports into actionable cases and communicate clearly and empathetically with customers of all technical levels, especially during high-impact or time-sensitive situations.
You'll spot patterns across support tickets and recommend improvements to documentation, tooling, and the product itself. You'll mentor junior team members and help raise the overall bar for support quality. This role is ideal for someone who thrives in async, fast-paced environments and is excited about building developer tools that scale to millions.
Supabase is a remote-first, globally distributed company of ~400 team members across 60+ countries. The company has raised over $1B in funding, including a $500M Series F round, and serves 540,000+ community members. We move fast, build in public, and use what we ship.
REQUIREMENTS:
- 6+ years in technical support, backend engineering, SRE, or similar
- Deep knowledge of PostgreSQL internals (autovacuum behavior, WAL growth, long-running transactions, table bloat)
- Strong high-performance SQL and query optimization skills
- Comfortable troubleshooting complex setups, including multi-tenant schema patterns
- Ability to debug edge functions and understand distributed system behavior
- Hands-on experience with data migration issues (pg_dump/restore, schema drift, failed migrations) and safe recovery procedures
- Hands-on experience with cloud hosting providers like AWS
- Comfortable in terminal and Linux environments
- Ability to thrive in high-volume situations and form/test assumptions quickly
- Fluent bilingual Japanese/English speaker (required)
- Experience supporting complex technical products in Japanese with native speakers (required)
- Ideally located in Japan, but location flexible as long as you can work during Japan business hours
