AI is a fundamental part of how work gets done at Gusto. We expect all team members to actively engage with AI tools relevant to their role and grow their fluency as the technology evolves. AI experience requirements vary by role and will be assessed during the interview process.

About the Role:

We're looking for an experienced infrastructure engineer to help evolve how Gusto stores and accesses data as the company scales. You'll help build a platform that lets engineering teams provision and access new datastores, evaluate and stand up highly available, horizontally scalable storage systems, and continue strengthening the resilience of the databases our product already depends on. This is a high-impact role shaping both the tools and the technology choices behind Gusto's storage layer.

About the Team:

The Datastores Infrastructure Engineering team designs, builds, and operates the data platforms that power Gusto's product: Kafka, MySQL, Postgres, and Redis. As Gusto grows, we're rethinking how the rest of engineering provisions and accesses storage — building self-service tooling for new datastores, exploring and adopting highly available, horizontally scalable systems, and continuing to reduce blast radius and improve the resilience of the databases we already operate.

Here's what you'll do day-to-day:
- Build the tooling and platform that let engineering teams provision and access new datastores, and evaluate and pilot highly available, horizontally scalable storage systems to meet Gusto's growing needs
- Take ownership of Kafka, from capacity planning and partitioning through performance tuning and reliability at scale, and help stand up and operate new non-relational datastores like DynamoDB
- Coordinate migrations and topology changes across the datastore platform (MySQL, Postgres, Redis, Kafka) with minimal disruption to production
- Drive efficiency and reliability improvements across the platform through query and consumer optimization, caching strategies, and workload management, backed by strong automation and standards for data consistency, integrity, and security
- Participate in on-call and drive long-term, sustainable reductions in operational burden
- Partner with product engineering teams to enable rapid, reliable product development, and share knowledge to grow the team's collective operating expertise

Here's what we're looking for:

6+ years of software engineering experience building and operating large-scale infrastructure systems, with deep hands-on expertise in streaming infrastructure (Kafka) and/or non-relational datastores (DynamoDB or similar) in production at scale
Strong understanding of distributed systems fundamentals—partitioning, replication, consistency models, and failure modes—and proven experience coordinating migrations or topology changes in production with minimal disruption
Experience running production infrastructure in the cloud, including caching systems like Redis/ValKey and streaming platforms like Kafka, with a track record of driving infrastructure optimization at scale
Strong communication skills, with the ability to simplify technical complexity and collaborate on technical direction across teams
Curiosity and ability to operate in an AI-native environment, using AI tooling to drive improvements in query optimization, performance evaluation, and infrastructure automation
Bonus: Experience with self-hosted distributed databases on Kubernetes (e.g., TiDB, CockroachDB, Vitess, or Citus), horizontal sharding, or service/vertical extraction from monolithic architectures
Bonus: Experience working with Ruby on Rails or similar MVC frameworks at scale

Our cash compensation amount for this role is targeted at $183,000-$200,000 /yr in Denver & most remote locations, and $222,000-$245,000 /yr for San Francisco, Seattle & New York. Final offer amounts are determined by multiple factors, including candidate experience and expertise, and may vary from the amounts listed above.

Gusto has physical office spaces in Denver, San Francisco, and New York City. Employees who are based in those locations will be expected to work from the office on designated days approximately 2-3 days per week (or more depending on role). The same office expectations apply to all Symmetry roles, Gusto's subsidiary, whose physical office is in Scottsdale.

Note: The San Francisco office expectations encompass both the San Francisco and San Jose metro areas.

When approved to work from a location other than a Gusto office, a secure, reliable, and consistent internet connection is required. This includes non-office days for hybrid employees.
