About Centric Software:

Centric Software® is a global leader, providing an innovative and AI-enabled product-concept-to-commercialization platform for retailers, brands and manufacturers of all sizes. We equip retail, fashion, luxury, footwear, outdoor, home and consumer goods brands with pioneering best-of-breed solutions to plan, design, develop, source, comply, buy, make, price, allocate, sell and replenish products. Our technology powers brands to streamline processes, drive efficiency and operate with confidence in an ever-changing market.

Our story is one of rapid growth, bold ideas and extraordinary opportunities. We’re here to challenge the status quo—and we’re looking for brilliant people who want to do the same. No matter where you are in the world, this is your chance to be part of something exceptional.

Position Summary

We are seeking a PostgreSQL expert to join our R&D Customer Support team as a Production DBA. This role is focused on bringing deep Postgres expertise in-house to analyze, troubleshoot, and improve production database environments, perform root cause analysis on issues ranging from long-running queries to hosting environment problems and heavy traffic scenarios, and ensure our customers’ PostgreSQL deployments remain healthy, performant, and reliable. While the primary focus is production operations, the DBA will also work across development environments as needed to trace issues to their source and collaborate with engineering on fixes.

Position Details

Job title: PostgreSQL Database Administrator (Production DBA)

Team: R&D – Customer Support

Location: Remote (US/Canada)

Employment Type: Full-time

Compensation: $136K USD

Key Responsibilities

Serve as the PostgreSQL expert and primary Production DBA within the R&D Customer Support team, driving the stability, performance, and reliability of customer-facing database environments.
Perform root cause analysis (RCA) on production incidents spanning query performance, database configuration, infrastructure-level bottlenecks, and traffic/load conditions.
Diagnose and resolve complex PostgreSQL performance, availability, and data-integrity issues, including query tuning, index strategy, vacuum/auto vacuum behavior, and lock contention.
Troubleshoot and analyze production PostgreSQL systems across diverse hosting environments, ensuring performance, availability, and data integrity.
Review execution plans, analyze slow queries, and recommend configuration, schema, or indexing changes to optimize production workloads.
Support customers running PostgreSQL across on-premises, cloud (AWS RDS/Aurora, Azure, GCP), and self-managed deployments.
Work across development and production environments to trace issues to their source and collaborate with engineering on fixes and product improvements.
Advise on high-availability and disaster-recovery architectures including streaming replication, logical replication, failover, backup/restore (pg_basebackup, pgBackRest, WAL-G), and point-in-time recovery.
Create and maintain internal knowledge-based articles, runbooks, and best-practice documentation for the support team.
Mentor support engineers and developers on Postgres internals, SQL tuning, and operational best practices.
Participate in on-call rotation for critical customer escalations as needed.

Required Qualifications

Minimum 5 years of hands-on experience as a PostgreSQL DBA, with deep knowledge of Postgres internals (MVCC, WAL, query planner, locking, buffer management) and operational best practices.
Proven track record managing PostgreSQL in production environments, including incident response, root cause analysis, and performance optimization under heavy traffic.
Strong SQL skills, including query optimization and execution-plan analysis (EXPLAIN / EXPLAIN ANALYZE).
Experience with PostgreSQL performance tuning: indexing strategies, autovacuum, connection pooling (PgBouncer), and configuration tuning (postgresql.conf).
Experience with high availability and replication: streaming replication, logical replication, Patroni, or equivalent.
Experience with backup and recovery tooling such as pgBackRest, WAL-G, pg_basebackup, or Barman.
Proficiency with Linux/Unix operating systems and shell scripting (Bash or similar).
Strong written and verbal communication skills, with the ability to explain complex database concepts to both technical and non-technical audiences.
Located in North America with the ability to work core hours that overlap with the team.

Preferred Qualifications

Experience supporting PostgreSQL on AWS RDS, Aurora Postgres, Azure Database for PostgreSQL, or Google Cloud SQL.
Scripting or automation experience in Python, PowerShell, or similar.
Familiarity with monitoring/observability tooling (Datadog, New Relic, Prometheus, pganalyze, Sentry).
Experience working in a customer-facing or customer-support-adjacent role.
Exposure to additional database platforms (Oracle, SQL Server, MySQL, MongoDB) and migration experience to/from Postgres.
Experience with infrastructure-as-code (Terraform, CloudFormation) and containerized workloads (Kubernetes).

What Success Looks Like

In the first 90 days, the successful candidate will have ramped up on our product and support workflows, taken ownership of escalated Postgres cases, and begun contributing to internal documentation and knowledge sharing. Within six months, they will be the go-to Postgres resource for the team, materially reducing time-to-resolution on database-related customer issues and partnering with engineering on product improvements informed by field data.
