Job summary

tastytrade, headquartered in Chicago, seeks a Senior PostgreSQL Database Administrator / Database Engineer to own Postgres health and performance across on‑prem and AWS RDS environments. This hands-on role collaborates with developers on migrations, optimizes queries, and leads incident response and DR planning.

You’ll partner with engineering teams to design scalable, highly available Postgres clusters, implement robust backup/restore, and drive automation and documentation to improve

Qualifications

• Deep PostgreSQL expertise with the query planner and EXPLAIN output interpretation.
• Experience with indexing strategies across B-tree, GIN, GiST, BRIN, and partial/indexed views.
• Proven ownership of backup/restore programs and DR testing.

Responsibilities

• Own performance for high-volume OLTP Postgres workloads: query plan analysis, index strategy, statistics and autovacuum tuning, connection pooling, partitioning, and schema design review.
• Design, deploy, and operate highly available clusters using Patroni, including replication topology, failover and switchover procedures, and regular testing.
• Own the backup and recovery program end to end — backup tooling, retention, PITR, and routine restore verification with documented RTO/RPO.
• Manage Postgres in both on-prem and Amazon RDS for PostgreSQL environments, including parameter groups, extension availability, failover behavior, and upgrade paths.
• Plan and execute major-version upgrades and large migrations with minimal downtime.
• Review application code and migrations written in Ruby (Rails/ActiveRecord) and Java (JDBC), catching N+1 queries, unsafe DDL, missing indexes, and lock-taking migrations before production.
• Build and maintain observability for the database tier: metrics, slow query capture, lock and wait-event analysis, and capacity forecasting.
• Automate routine operations and contribute to runbooks; participate in on-call rotation and postmortems.
• Write and maintain internal documentation: runbooks, architecture decisions, upgrade playbooks, and developer guidance.

Job description

Company: tastytrade

Role: Senior PostgreSQL Database Administrator / Database Engineer

Location: Chicago, IL — Hybrid

About the Role

As a Senior PostgreSQL Database Administrator / Database Engineer, you'll own the health, performance, and durability of high-throughput Postgres clusters running both on bare metal / on-prem VMs and on Amazon RDS. This is a hands-on role: you will read query plans, tune indexes, run failover drills, review application code, and write high-quality documentation.

This is not a ticket-queue DBA position. You will work inside the development process — reviewing migrations before they ship, pairing with application teams on data access patterns, assisting with performance troubleshooting, and contributing to incident resolution and process improvement.

What You'll Do:

• Own performance for high-volume OLTP Postgres workloads: query plan analysis, index strategy, statistics and autovacuum tuning, connection pooling, partitioning, and schema design review.

• Design, deploy, and operate highly available clusters using Patroni, including replication topology, failover and switchover procedures, and regular testing.

• Own the backup and recovery program end to end — backup tooling, retention, PITR, and, most importantly, routine restore verification with documented RTO/RPO.

• Manage Postgres in both on-prem and Amazon RDS for PostgreSQL environments, including the operational differences between them (parameter groups, extension availability, failover behavior, upgrade paths).

• Plan and execute major-version upgrades and large migrations with minimal downtime.

• Review application code and database migrations written in Ruby (Rails/ActiveRecord) and Java (JDBC), catching N+1 queries, unsafe DDL, missing indexes, and lock-taking migrations before they reach production.

• Build and maintain observability for the database tier: metrics, slow query capture, lock and wait-event analysis, and capacity forecasting.

• Automate routine operations. Manual runbooks are a starting point, not a destination.

• Participate in an on-call rotation: lead incident response, write postmortems, and file follow-up tickets to prevent recurrence.

• Write and maintain internal documentation: runbooks, architecture decision records, upgrade playbooks, and developer-facing guidance on using Postgres well.

• Assist in sizing and future scaling of on-prem server hardware.

• Participate in disaster recovery planning and exercises.

Who You Are:

• You have deep PostgreSQL expertise with the query planner — you can read EXPLAIN (ANALYZE, BUFFERS) output and explain why the planner chose a plan, not just that it was slow.

• You have hands-on indexing strategy experience across B-tree, GIN, GiST, BRIN, partial, expression, and covering indexes, including the write-amplification cost of each.

• You understand replication — physical and logical replication, replication slots, lag diagnosis, and the failure modes of each.

• You must have production experience with Patroni-managed clusters, including having handled a real failover.

• You must have proven ownership of a backup and restore program (pgBackRest, Barman) — including having performed a production restore under pressure.

• You have experience operating Postgres at meaningful scale in both self-managed (on-prem/VM/bare metal) and managed RDS environments.

• You must have strong Linux fundamentals: filesystem and I/O behavior, memory and hugepages, systemd, networking, and performance tooling.

• You have a software development background: creating, reviewing, and merging pull requests as part of a mandatory peer review process, and writing runbooks and design documentation.

• You have working proficiency in Ruby and Java, with enough Python literacy to read, review, and modify it confidently.

• You must be an excellent written communicator. Clear incident summaries, review comments, and design proposals are a core part of this job, not an afterthought.

• You have excellent documentation practice — a demonstrated habit of leaving systems better documented than you found them.

Preferred Qualifications:

• Experience with connection poolers (PgBouncer) at scale.

• Infrastructure-as-code and configuration management (Terraform, Ansible, SaltStack, Puppet, etc.).

• Kubernetes-hosted Postgres operators.

• Active-active multi-site architecture.

• Experience with logical replication–based zero-downtime migrations.

• Contributions to Postgres or its ecosystem tooling.

• Familiarity with our internal tooling, including [gascan].
