About the Role:
- End to end ownership of our database and data warehousing infrastructure, its KPIs and its SLAs, including MySQL, Postgres, CDC capture, and Redshift.
- Lead optimizations in database and query performance.
- Build and maintain tooling to help manage and upgrade our data infrastructure, continually improving with migrations and optimizations.
- Partner with Development to ensure we ship solid queries against a battle-tested schema to meet the needs of our products and business.
About the Role:
- Help Sezzle evolve our data systems beyond the current scale and stack with whatever tooling is necessary to handle processing high volumes of writes and events while performing complex ETL.
- Evaluate and integrate new technologies, guiding the evolution of Sezzle’s data infrastructure.
- Help data engineers and analysts optimize Redshift and warehouse performance, including query tuning, modeling improvements, and cost management.
What We look for:
- 12+ years of experience in DBA, SRE, or Data Engineering roles, with a strong track record of scaling production-grade systems.
- Deep expertise with MySQL, Postgres, AWS Redshift or similar products, including performance tuning, table design, and workload management.
- Advanced proficiency in SQL.
- Strong hands-on experience with data replication and ETL/ELT frameworks, especially DBT, AWS DMS, or similar tools.
- Strong understanding of data modeling, distributed systems, and warehouse/lake design patterns.
- Ability to work in a fast-paced, collaborative environment with excellent communication and documentation skills.
- Demonstrated experience working with Claude or equivalent large language model tools is required; candidates must be comfortable leveraging AI to enhance productivity, research, and communication.
Preferred Knowledge and Skills:
- Prior experience in high-growth, data-intensive fintech or similar regulated environments.
- Knowledge of lakehouse architectures and modern stacks such as Snowflake, Databricks, Iceberg, or Delta Lake.
- Some background in designing scalable, fault-tolerant data pipelines using modern orchestration tools (Airflow, Dagster, Prefect, etc.) processing anywhere from 100GB to 1 TB of new data a day
- Familiarity with streaming technologies (Kafka, Kinesis, Flink, Spark Streaming).
- High enthusiasm for using AI to be as productive as possible.
About You:
- You have relentlessly high standards - many people may think your standards are unreasonably high. You are continually raising the bar and driving those around you to deliver great results. You make sure that defects do not get sent down the line and that problems are fixed so they stay fixed.
- You’re not bound by convention - your success—and much of the fun—lies in developing new ways to do things
- You need action - speed matters in business. Many decisions and actions are reversible and do not need extensive study. We value calculated risk-taking.
- You earn trust - you listen attentively, speak candidly, and treat others respectfully.
- You have backbone; disagree, then commit - you can respectfully challenge decisions when you disagree, even when doing so is uncomfortable or exhausting. You have conviction and are tenacious. You do not compromise for the sake of social cohesion. Once a decision is determined, you commit wholly.
- You deliver results - you focus on the key inputs and deliver them with the right quality and in a timely fashion. Despite setbacks, you rise to the occasion and never settle.
