The role, at a glance.
Supabase is seeking a senior bilingual Japanese/English Database Support Engineer to resolve complex customer issues across its Postgres-based developer platform. The role requires deep PostgreSQL expertise, including query tuning, WAL, autovacuum, transaction behavior, table bloat, migrations, and recovery. This engineer will reproduce defects, isolate root causes, provide workarounds, and escalate well-documented cases to product engineering. The position also involves proactive customer guidance, identifying recurring support patterns, improving documentation and tooling, and mentoring junior support staff. It is a fully remote, high-volume role aligned to Japan business hours.

Sample interview questions
I would first inspect replication slots, long-running transactions, archive status, checkpoint behavior, and write-heavy workloads. I would identify the process retaining WAL, validate the risk of removing or advancing any replication dependency, then recommend a safe mitigation and document the root cause.
I would gather the query, parameters, schema details, row counts, execution plan, PostgreSQL version, and workload context. I would use EXPLAIN ANALYZE to identify expensive operations, assess indexes and statistics, test a safe optimization, and explain both the immediate workaround and durable fix.
I ask targeted questions about expected versus actual behavior, timestamps, project configuration, logs, reproducible steps, and recent changes. I then create a minimal reproduction, capture evidence, state the impact and scope, and provide engineering with a concise hypothesis and any known workaround.
I would pause further writes or deployments where appropriate, compare the intended migration history with the live schema, and determine whether the failure was transactional. After taking or validating backups, I would prepare an idempotent recovery plan, test it in a safe environment, and clearly communicate risks before applying changes.
I would acknowledge the issue promptly in Japanese, establish impact and urgency, and provide clear status updates with confirmed facts and next steps. In parallel, I would maintain an English incident summary for engineering with timestamps, logs, reproduction details, and customer impact, ensuring both audiences receive accurate and empathetic communication.

About the Role
We’re looking for an experienced, fluent Japanese speaking Database Support Engineer to join our Support Team and help developers unblock complex issues, build more reliably, and get the most out of the Supabase platform. You’ll work closely with customers and engineering, helping us improve product quality and developer experience based on real-world usage.
This role is ideal for someone who thrives in async, fast-paced environments and is excited about building developer tools that scale to millions.
What You’ll Be Responsible for
In this role, you’ll:
Investigate and resolve advanced customer issues across Postgres, Auth, RLS, Storage, Realtime, Edge Functions, and client libraries.
Provide consultative, proactive advice to optimize workloads, avoid common pitfalls, and tailored advice to our most advanced users.
Reproduce bugs, isolate root causes, propose workarounds, and escalate to engineering with solid repro steps.
Ask smart, targeted questions that turn incomplete reports into actionable cases.
Communicate clearly and empathetically with customer users of all levels—especially during high-impact or time-sensitive situations.
Spot patterns across tickets and recommend improvements to docs, tooling, and the product itself.
Mentor junior team members and help raise the overall bar for support quality.
You Might Be a Good Fit If You
You have 6+ years in technical support, backend engineering, SRE, or similar.
You know PostgreSQL deeply—autovacuum behavior, WAL growth, long-running transactions, table bloat, and other internals.
You’re strong in high-performance SQL and query optimization.
You’re comfortable troubleshooting complex setups, including multi-tenant schema patterns.
You can debug edge functions and understand distributed system behavior when failures get tricky.
You’ve handled data migration issues (pg_dump/restore, schema drift, failed migrations) and know how to recover safely.
You have hands-on experience with cloud hosting providers like AWS.
You’re comfortable in terminal and Linux environments.
You thrive in high-volume situations and can form/test assumptions quickly.
Additional Requirements
Must be a fluent bilingual Japanese/English Speaker
Must have experience support complex technical products in Japanese with native speakers
Ideally located in Japan, but location is flexible as long as you can work during Japan business hours.
