You’ll build and scale the company’s cache services on Redis and Valkey, own end‑to‑end cluster migrations, productionize clusters (capacity planning, failover, upgrades) and automate self‑service provisioning workflows, while operating the fleet in production and defining SLOs and alerting.
2+ years of software engineering experience, proficiency in Python or Kotlin, and hands‑on work with Redis/Valkey or a comparable in‑memory store; familiarity with AWS, MySQL, Terraform, Kubernetes, and distributed‑system concepts; on‑call experience and strong verbal and written communication skills.
Cache services underpin mission‑critical financial transaction data and other high‑volume workloads, so reliable, automated, and scalable Redis/Valkey infrastructure directly impacts product performance, cost efficiency, and the ability to deliver honest financial products at scale.
Engineers who enjoy owning infrastructure end‑to‑end, love tackling distributed‑system challenges, have a track record of automating operations, and thrive in collaborative, fast‑moving environments with on‑call responsibilities.
At Affirm, we exist for the moments that matter—giving people a clear, predictable way to pay over time, with no hidden fees, no surprises, and no tradeoffs on what matters most.
The Data and Storage Services team is responsible for Affirm's data infrastructure across OLTP and OLAP systems, spanning critical online checkout databases, batch orchestration, streaming infrastructure, event-driven frameworks, BI, analytics tooling, large-scale data platforms, and agentic data tools such as semantic layers and internal platform data applications. Our mission is to provide trustworthy, intuitive, and cost-efficient solutions for Affirmers to secure, store, analyze, and transform data at exceptional scale.
The Online Storage team provides a set of managed databases as a platform, used to persist data for all Affirm services. Our platform enables self-service access to OLTP storage systems, including Relational DB(MySQL), KV(DynamoDB), Distributed SQL(TiDB) and Cache(Redis). As a team, we are responsible for various data and access patterns, including but not limited to mission-critical financial transactional data, data science models, and any new persistence use case. These responsibilities require us to learn and gain deep expertise in various database systems.
We are looking for a talented Software Engineer who can build and scale Cache Services (Redis and Valkey) identifying opportunities to improve how we migrate, productionize, operate, self-service and improve this mission-critical infrastructure to unlock substantial value within our business. You’ll have the opportunity to directly influence your team’s roadmap in close collaboration with your peers, share your knowledge and expertise with others and learn from some of the best on our shared mission to deliver honest financial products that improve lives.
