Staff Database Reliability Engineer at Scribe in Remote

ABOUT THE ROLE We'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 MATTERS You 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 liability: - Review migrations for safety at scale — locks, backfills, concurrent index builds, NOT VALID constraints - Catch N+1 patterns and missing select_related/prefetch_related in review - Establish 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 emerge Lead major infrastructure initiatives: - Capacity planning as traffic and engineering throughput grow - Zero-downtime schema migrations and cutovers - Multi-AZ resilience within a single region — Aurora writer/reader placement, failover behavior and RTO/RPO, ElastiCache and OpenSearch AZ topology, RabbitMQ survivability across AZs - Backups, PITR, failover testing, retention Own the CDC pipeline (Aurora → DMS → S3 Parquet → Snowflake): - DMS task design and tuning, replication slot hygiene on the Postgres side - Schema evolution as Django migrations roll through — so a column rename doesn't silently break the warehouse at 6 AM - Parquet layout and partitioning, reliability of the Snowflake handoff - Automated checks that flag migrations likely to break downstream consumers Drive observability across three complementary tools: - pganalyze — 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, DMS - Honeycomb — high-cardinality tracing that ties slow DB calls back to users, flags, deploys, and flows - Shape how the three fit together, including Django-side instrumentation and trace attributes on ORM queries Build tooling and guardrails: - Migration review automation and CI checks for risky patterns - Slow query pipelines fed from pganalyze - Self-service dashboards so teams understand their own query footprint Support and evolve the rest of the stack: - OpenSearch — index design, sharding, mapping changes, reindexing strategy, Django-side indexing pipelines - Redis — caching patterns, eviction, sizing, Django cache framework, Celery/RQ usage, avoiding hot keys and thundering herds - SQS + RabbitMQ — queue design, DLQs, visibility timeouts, exchange/queue topology, AZ mirroring, consumer backpressure, Celery behavior under load WHAT MAKES YOU A GREAT FIT Core expertise: - Deep 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 subqueries - Single-region multi-AZ design — practical understanding of what it does and doesn't protect against Data movement and observability: - Production 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 useful AI-assisted workflow: - Real experience making AI coding and review tools useful for a team — writing AGENTS.md files, configuring review agents, versioning and iterating on prompts and configs The rest of the stack: - OpenSearch at scale — sizing, sharding, JVM tuning, rolling upgrades, snapshots - Production Redis — persistence tradeoffs, cluster mode, hot keys, thundering herds - At least one production message broker (SQS, RabbitMQ, Kafka) — delivery semantics, idempotency, failure modes Engineering and leadership: - Strong automation and IaC background — real code (Python, Go, or similar) and Terraform - Track record leading cross-team initiatives, writing design docs that hold up, influencing without authority - Comfortable in a high-growth environment where the right answer for 50 engineers isn't the right answer for 100 - Pragmatic outlook during incidents — focused on preventing the next one FULL-TIME US EMPLOYEE BENEFITS INCLUDE - Some of the nicest and smartest teammates you’ll ever work with - Competitive salaries - Comprehensive healthcare benefits - Exciting and motivating equity - Flexible PTO - 401k - Parental Leave - Commuter Benefits (SF office employees) - WFH Stipend Compensation $225-$250k base + equity We 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. We believe this benefits not only our employees but our product, customers, and community as well. Scribe is proud to be an Equal Opportunity Employer.
