Staff Database Reliability Engineer

About The RoleWe're hiring a Staff Database Reliability Engineer to own the strategy, architecture, and operational excellence of our data infrastructure. This is an expert-level IC role with deep influence on engineering direction, partnering closely with platform, backend, and DevOps engineers.Why this role mattersYou will own the data tier end-to-end. Design schemas and access patterns that scale, tune Aurora for latency and throughput, and set the standards for how engineers interact with our databases. When a migration script seizes up mid-deploy and writes start queueing behind an ACCESS EXCLUSIVE lock, your runbooks and automation resolve the incident quickly.Make The Django ORM a Strength, Not a LiabilityReview migrations for safety at scale — locks, backfills, concurrent index builds, NOT VALID constraintsCatch N+1 patterns and missing select_related/prefetch_related in reviewEstablish conventions for QuerySet usage and physical schema design (indexes, constraints, partitioning)Scale review through automation, not heroics — author AGENTS.md files and DNA scaffolding that encode our conventions, configure AI review bots (Claude Code, Cursor, etc.) to flag risky migrations and ORM anti-patterns, and iterate on those configs as new failure modes emergeLead Major Infrastructure InitiativesCapacity planning as traffic and engineering throughput growZero-downtime schema migrations and cutoversMulti-AZ resilience within a single region — Aurora writer/reader placement, failover behavior and RTO/RPO, ElastiCache and OpenSearch AZ topology, RabbitMQ survivability across AZsBackups, PITR, failover testing, retentionOwn The CDC Pipeline (Aurora → DMS → S3 Parquet → Snowflake)DMS task design and tuning, replication slot hygiene on the Postgres sideSchema evolution as Django migrations roll through — so a column rename doesn't silently break the warehouse at 6 AMParquet layout and partitioning, reliability of the Snowflake handoffAutomated checks that flag migrations likely to break downstream consumersDrive Observability Across Three Complementary Toolspganalyze — query-level performance, index advisor, schema insights - the go-to for "why is this ORM query slow"CloudWatch — infrastructure metrics and alarms for Aurora, OpenSearch, ElastiCache, SQS, DMSHoneycomb — high-cardinality tracing that ties slow DB calls back to users, flags, deploys, and flowsShape how the three fit together, including Django-side instrumentation and trace attributes on ORM queriesBuild Tooling And GuardrailsMigration review automation and CI checks for risky patternsSlow query pipelines fed from pganalyzeSelf-service dashboards so teams understand their own query footprintSupport And Evolve The Rest Of The StackOpenSearch — index design, sharding, mapping changes, reindexing strategy, Django-side indexing pipelinesRedis — caching patterns, eviction, sizing, Django cache framework, Celery/RQ usage, avoiding hot keys and thundering herdsSQS + RabbitMQ — queue design, DLQs, visibility timeouts, exchange/queue topology, AZ mirroring, consumer backpressure, Celery behavior under loadWhat makes you a great fitCore ExpertiseDeep PostgreSQL — EXPLAIN (ANALYZE, BUFFERS), MVCC, bloat, lock contention, vacuum/autovacuum. Aurora Serverless V2 / Limitless experience strongly preferred (storage model, reader/writer split, ACU scaling)Strong ORM fluency (Django, SQLAlchemy, ActiveRecord, or similar) — predict the SQL a query will generate, spot N+1 problems on sight and how to control eager loading (joins vs. batched IN queries), column projection, aggregations, and subqueriesSingle-region multi-AZ design — practical understanding of what it does and doesn't protect againstData Movement And ObservabilityProduction CDC experience, ideally AWS DMS — comfortable with logical replication, slot hygiene, schema evolution, and Parquet-based data lakes feeding Snowflake (or BigQuery/Redshift)Hands-on with pganalyze (or Datadog DBM / Performance Insights / pg_stat_statements pipelines), CloudWatch (custom metrics, composite alarms, log insights), and Honeycomb (or another high-cardinality tracing tool) — comfortable with OpenTelemetry and opinionated about what makes a trace usefulAI-assisted WorkflowReal experience making AI coding and review tools useful for a team — writing AGENTS.md files, configuring review agents, versioning and iterating on prompts and configsThe Rest Of The StackOpenSearch at scale — sizing, sharding, JVM tuning, rolling upgrades, snapshotsProduction Redis — persistence tradeoffs, cluster mode, hot keys, thundering herdsAt least one production message broker (SQS, RabbitMQ, Kafka) — delivery semantics, idempotency, failure modesEngineering And LeadershipStrong automation and IaC background — real code (Python, Go, or similar) and TerraformTrack record leading cross-team initiatives, writing design docs that hold up, influencing without authorityComfortable in a high-growth environment where the right answer for 50 engineers isn't the right answer for 100Pragmatic outlook during incidents — focused on preventing the next oneFull-Time US Employee Benefits IncludeSome of the nicest and smartest teammates you’ll ever work withCompetitive salariesComprehensive healthcare benefitsExciting and motivating equityFlexible PTO401kParental LeaveCommuter Benefits (SF office employees)WFH StipendCompensation$200k-$250k base + equityWe consider several factors when determining compensation, including location, experience, and other job-related factors.At Scribe, we celebrate our differences and are committed to creating a workplace where all employees feel supported and empowered to do their best work.
