We’re not just transforming payments; we’re redefining how people discover, interact with, and purchase the things they love while driving real impact on merchant sales through increased conversions and higher order values. As we continue to shape the future of fintech and retail, we’re building an innovative, dynamic team passionate about creating more than just a transaction but a truly unique shopping journey. If you’re excited about pushing boundaries in tech and delivering a game-changing experience for consumers and merchants alike, come join us at Sezzle and help create the future of shopping!\nAbout the Role: \nWe are seeking a technically strong, hands-on Senior Database Reliability Engineer to help design, build, and scale the database platform used across Sezzle’s applications.\nThis is not a traditional DBA role. This role is for an engineer who can combine deep database knowledge with software engineering, infrastructure engineering, and platform thinking. You will help build the systems, libraries, automation, standards, and guardrails that make database usage across Sezzle reliable, secure, scalable, and easy for developers to adopt correctly.\nAs a Senior Database Reliability Engineer, you will be responsible for improving how Sezzle applications connect to, migrate, operate, observe, and scale their databases. You will work across application teams, infrastructure, security, and engineering leadership to define patterns that improve database reliability by design - not just by operational response.\nYou should be comfortable owning problems end-to-end: understanding application behavior, reading code, reviewing database access patterns, building shared tooling, improving connection management, designing migration safety checks, analyzing production performance, and helping developers use databases in safer and more scalable ways.\nYou should consider yourself a DOer to be a good fit for this role. We are looking for someone who can ship production-quality engineering work, not just advise from the sidelines. With AI tooling and automation, you should be a force multiplier for database reliability, developer productivity, and operational excellence across Sezzle.\nCompensation:\nFor this senior development role, with 6+ years of experience, the compensation range is $5,000 - $9,500 USD per month. This range acknowledges the extensive expertise, leadership capabilities, and significant contributions expected at this level, offering a competitive salary to reflect the value of advanced skills and experience.\nWhat You'll Do:\nDesign, build, and maintain shared database platform components used by Sezzle applications, such as database connection packages, database client libraries, migration tooling, safety checks, query standards, and developer-facing abstractions.\nEstablish reliable, scalable patterns for how Sezzle services connect to and interact with relational databases across production, staging, and development environments.\nPartner with backend engineering teams to improve database usage in application code, including connection lifecycle, transaction handling, retries, timeouts, pooling, query patterns, and migration workflows.\nBuild automation and internal tooling that makes database operations safer, more repeatable, and less dependent on manual intervention.\nDefine and enforce engineering standards for database access, schema design, migrations, indexing, query performance, connection management, and operational readiness.\nArchitect and improve database infrastructure across AWS RDS/Aurora MySQL, PostgreSQL, RDS Proxy, read replicas, backups, failover, parameter groups, monitoring, and capacity planning.\nLead database reliability initiatives that reduce operational risk, improve performance, and help Sezzle scale safely.\nReview application designs and database changes early in the development lifecycle to ensure reliability, scalability, maintainability, and security are built in from the start.\nBuild guardrails for database migrations, including automated checks, rollback expectations, schema review workflows, migration observability, and production safety controls.\nImprove developer self-service for database provisioning, access, schema management, local development, testing, and observability.\nInvestigate production database issues by combining application telemetry, database metrics, logs, query plans, traces, and cloud infrastructure data.\nIdentify and fix systemic database problems, not just symptoms - including bad access patterns, unsafe migrations, inefficient queries, connection storms, lock contention, replication lag, and capacity bottlenecks.\nCreate and maintain high-signal dashboards, alerts, SLOs, SLIs, runbooks, and operational readiness checks for database-backed services.\nDrive improvements in database backup validation, restore testing, disaster recovery, failover readiness, and business continuity.\nWork with security and compliance teams to improve database access controls, auditability, encryption, secrets management, least privilege, and PCI/SOC 2 aligned controls.\nMentor engineers on database design, query performance, safe migrations, operational readiness, and production debugging.\nUse automation and AI tooling where appropriate to improve migration review, query analysis, incident investigation, documentation, and developer productivity.\nWhat We look for: \n6+ years of professional software engineering, infrastructure engineering, database engineering, SRE, or platform engineering experience.\nStrong software engineering ability in at least one production programming language such as Go, Python, or TypeScript.\nProven ability to build production-quality internal tools, libraries, frameworks, services, or platform components used by other engineers.\nDeep hands-on experience with relational databases, especially MySQL and/or PostgreSQL, in high-availability production environments.\nStrong understanding of how application code interacts with databases, including connection pooling, transactions, isolation levels, retries, timeouts, deadlocks, locking, migrations, and query execution.\nExperience designing or improving shared database access patterns, internal database packages, ORM wrappers, migration frameworks, or developer-facing database tooling.\nHands-on experience with AWS RDS/Aurora, including provisioning, upgrades, replicas, backups, failover, monitoring, parameter tuning, and production troubleshooting.\nExperience with database connection management technologies such as RDS Proxy, PgBouncer, ProxySQL, or application-level pooling.\nStrong ability to analyze database performance using query plans, indexes, slow query logs, wait events, locks, metrics, and application traces.\nExperience designing safe database migration processes for production systems.\nStrong understanding of observability for database-backed applications, including metrics, logs, traces, SLOs, alerting, and incident response.\nExperience with infrastructure-as-code and CI/CD systems such as Terraform, GitLab CI/CD, Kubernetes, Helm, or similar tooling.\nAbility to influence engineering teams through clear design reviews, documentation, technical standards, and practical implementation.\nAbility to operate independently, identify high-impact problems, propose pragmatic solutions, and drive them to completion.\nDemonstrated experience working with Claude or equivalent large language model tools is required; candidates must be comfortable leveraging AI to enhance productivity, research, and communication.\nBachelor’s degree in Computer Science.\nPreferred Knowledge and Skills:\nExperience building platform capabilities for a microservices environment.\nExperience with Golang application development and database access patterns.\nExperience creating database libraries, SDKs, service templates, migration frameworks, or paved-road developer tooling.\nExperience improving database reliability across many services or teams, not just one application.\nExperience with fintech, payments, banking, e-commerce, or other high-volume transactional systems.\nExperience with compliance-sensitive environments such as PCI DSS, SOC 2, or SOX.\nExperience with database access governance, audit logging, secrets management, encryption, IAM authentication, and least-privilege access models.\nExperience with large-scale operational automation for provisioning, patching, failover testing, backup validation, access management, or schema review.\nExperience with distributed systems patterns such as transactional outbox, event-driven architecture, idempotency, queues, eventual consistency, and data consistency tradeoffs.\nExperience with observability tools such as Prometheus, Grafana, Datadog, CloudWatch, Performance Insights, OpenTelemetry, or New Relic.\nFamiliarity with Elasticsearch or other supporting data stores.\nFamiliarity with AI developer tooling such as Claude Code, Gemini CLI, Codex, Cursor, and using it to be a more productive engineer.\nAbout You: \nYou 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.\nYou’re not bound by convention - your success-and much of the fun-lies in developing new ways to do things\nYou need action - speed matters in business. Many decisions and actions are reversible and do not need extensive study. We value calculated risk-taking.\nYou earn trust - you listen attentively, speak candidly, and treat others respectfully.\nYou 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.\nYou 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.\nSezzle’s Technology Stack:\nLanguages: Golang, Typescript, Python\nFrontend: Typescript - React and React Native\nBackend: Golang\nDatabase: MySQL, Postgres, Elasticsearch\nDevOps & Cloud: AWS, Kubernetes\nVersion Control: Git\nCI/CD: Gitlab\nTesting: Developer and AI-driven, focus on automated end-to-end, integration, and unit tests\nOpen Source: Sezzle is focused on using open source, and we build what we can before buying!\nWhat Makes Working at Sezzle Awesome? \nAt Sezzle, we are more than just brilliant engineers, passionate data enthusiasts, out-of-the-box thinkers, and determined innovators; we are skilled musicians, yogis, cyclists, chefs, golfers, dog-lovers, and rock-climbers.
