About Us

Temporal is an open source programming model that can simplify code, make applications more reliable, and help developers focus on the important things like delivering features faster. We are on a mission to be the reliable foundation of every developer’s toolbox, and are building the team that will make that happen.

Our values guide us —they are present in how we show up, make decisions, and work together to make an impact. We’re curious, driven, collaborative, genuine and humble.

Temporal is growing and we are looking for those who share our values, challenge ‘standard’ thinking, and want to influence our future. If you have a passion for improving the developer experience, building world‑class open‑source software and communities, and want to be a part of our amazing team, we’d love to hear from you!

Summary

Cloud Data Store (CDS) owns the storage, retrieval, and lifecycle of all workflow data at planet scale. We design the persistence APIs, build storage abstractions that run across cloud vendors, and deliver the observability that lets customers trust their state machines for years.

As a Senior Software Engineer, you will design, build, and maintain significant portions of our backend functionality for highly scalable, multi‑tenant services. You’ll own the custom persistence stack for Temporal Cloud which includes a Write Ahead Log, various metadata stores, multi‑level caches, tiered storage, etc.

What You’ll Do

• Design & build distributed data systems – craft APIs, schemas, and replication paths that keep petabytes of workflow history durable and query‑able. Clearly document design choices and operational knowledge to successfully deploy and run the service with those features.
• Drive reliability & performance – own SLOs, create chaos‑test plans, profile hot paths, and lead incident reviews.
• Technical leadership – break down roadmap epics, mentor mid‑level engineers, steward design docs through RFC.
• Cross‑team collaboration – partner with the Server, Cloud, and DX teams to land features end‑to‑end.

What You’ll Bring

• 5 or more years of experience as an “Arranger” and/or “Builder/Enhancer” of highly scalable distributed systems.
• Solid computer science fundamentals in distributed systems concepts including multi‑threading and concurrency.
• Experience writing concurrent code in production with languages like Go or Java or other applicable languages with skill level as “high end of Intermediate” and/or “Advanced” or “Expert” levels.
• Experience building and running services on AWS. Bonus: Microsoft Azure and Google GCP experience.

Nice to Have

• Prior contributions to Temporal, Cadence, or other workflow engines.
• Deep expertise in a storage domain (LSM trees, columnar stores, transactional logs, etc.).
• Operated multi‑region, ≥99.99 % uptime services.
• Experience working with Open Source Systems.
• Experience in building K8s controllers and/or CRDs is a plus.

Compensation

• The estimated pay range for this role is $180,000 – $225,000 depending on locale.
• Additionally, this role is eligible to participate in Temporal’s equity plan.

Benefits

• Unlimited PTO, 12 holidays + 2 floating holidays
• 100 % premium coverage for medical, dental, and vision
• AD&D, LT & ST disability, and life insurance (standard & supplemental available)
• Empower 401K plan
• Additional perks for learning & development; lifestyle spending; in‑home office setup; professional memberships; WFH meals; internet stipend; and more!
