Why This Job is Featured on The SaaS Jobs
This Software Engineer role sits in a part of SaaS that often determines whether product velocity translates into reliable customer experience: shared infrastructure. A multi-tenant caching platform is foundational for API-driven products because it directly influences latency, availability, and predictable performance across many internal consumers, especially when workloads vary by tenant and feature.
From a SaaS career perspective, the work builds durable systems thinking around operating services that other teams depend on. Experience balancing tail latency, durability tradeoffs, and cost is highly portable across subscription businesses where margins and reliability targets are continuously measured. The emphasis on Kubernetes-based orchestration and cross-team interfaces also maps well to modern SaaS platform engineering, where infrastructure is treated as an internal product with its own roadmap.
This role is best suited to an engineer who prefers owning a core service end to end, from design through operations, and who enjoys reasoning from first principles about performance and failure modes. It will fit someone comfortable collaborating across infrastructure and product stakeholders, and who wants to deepen expertise in distributed caching, networking fundamentals, and production-grade automation.

Job Description
About the Team
At OpenAI, we’re building safe and beneficial artificial general intelligence. We deploy our models through ChatGPT, our APIs, and other cutting-edge products. Behind the scenes, making these systems fast, reliable, and cost-efficient requires world-class infrastructure.
The Caching Infrastructure team is responsible for building a caching layer that powers many critical use cases at OpenAI. We aim to provide a high-availability, multi-tenant cache platform that scales automatically with workload, minimizes tail latency, and supports a diverse range of use cases.
We’re looking for an experienced engineer to help design and scale this critical infrastructure. The ideal candidate has deep experience in distributed caching systems (e.g., Redis, Memcached), networking fundamentals, and Kubernetes-based service orchestration.
In This Role, You Will:
Design, build, and operate OpenAI’s multi-tenant caching platform used across inference, identity, quota, and product experiences.
Define the long-term vision and roadmap for caching as a core infra capability, balancing performance, durability, and cost.
Collaborate with other infra teams (e.g., networking, observability, databases) and product teams to ensure our caching platform meets their needs.
You Might Thrive In This Role If You:
Have 5+ years of experience building and scaling distributed systems, with a strong focus on caching, load balancing, or storage systems.
Have deep expertise with Redis, Memcached, or similar solutions, including clustering, durability configurations, client-side connection patterns, and performance tuning.
Have production experience with Kubernetes, service meshes (e.g., Envoy), and autoscaling systems.
Think rigorously about latency, reliability, throughput, and cost in designing platform capabilities.
Thrive in a fast-paced environment and enjoy balancing pragmatic engineering with long-term technical excellence.
