[Hiring] Site Reliability Engineer @FyerX

Role Description

We are seeking an experienced Database Site Reliability Engineer (DB SRE) to oversee the stability, performance, and scaling limits of our high-volume transaction databases. The ideal candidate will:

• Build automated cluster management tools.
• Orchestrate sub-millisecond query optimizations.
• Manage multi-region replication layers.
• Design fault-tolerant configurations to ensure maximum database uptime and zero data loss.

Key Responsibilities

• Design and maintain highly available database cluster topologies across public clouds, leveraging automated scaling, sharding mechanisms, and read-replica strategies.
• Optimize sub-millisecond database query performance, conducting rigorous index evaluations, identifying locking contentions, and rewrites of inefficient SQL scripts.
• Orchestrate automated backup and disaster recovery validation sweeps, configuring point-in-time recovery (PITR) parameters and multi-region failover tests.
• Build automated telemetry dashboards and proactive alerts utilizing monitoring frameworks (e.g., Prometheus, Grafana, Datadog) to track database health metrics (IOPS, CPU utilization, connections).
• Write robust automation scripts using Python, Go, or Bash to manage recurring database maintenance routines, schema migration deployments, and resource adjustments.
• Diagnose and remediate production database performance bottlenecks, resolving replication lags, connection pool limits, memory usage leaks, and deadlocks.
• Enforce data safety and governance protocols, configuring encryption-at-rest policies, fine-grained access parameters, and compliance masking routines to secure sensitive records.

Qualifications

• 5 to 9 years of core systems engineering or database administration experience.
• 4+ dedicated years actively managing high-scale, cloud-native relational databases (e.g., PostgreSQL, MySQL, Aurora) or NoSQL databases.
• Strong technical mastery of database engine configurations, connection poolers (e.g., PgBouncer), infrastructure automation (Terraform), and system telemetry structures.
• Deep structural understanding of write-ahead logging (WAL), isolation levels, transaction mechanics, distributed storage bounds, and network latency impacts.
• Mandatory certification: AWS Database Specialty, Certified Postgres Professional, or Oracle Database Admin Certified Professional.

Preferred Qualifications

• Prior experience implementing large-scale live database data migrations with minimal production operational windows.
• Familiarity with distributed database engines or streaming message queues (e.g., CockroachDB, Kafka, Debezium) for real-time change data capture (CDC).
