Job description

Senior Software Engineer, Open Source Nexus Server

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

As a Senior Software Engineer, you will get the chance to design, build, and maintain significant portions of our backend functionality for highly scalable, multi‑tenant Nexus services (Our durable execution framework for orchestrating work across team and application boundaries for improved modularity, security, debugging, and fault isolation). Examples of the key distributed systems components you’ll own include durable execution, async processing and expand our ability to invoke workflows through more industry standard protocols. Working in the highly collaborative Open Source Server org, we’ll look to build a new enterprise offering that involves both on‑premise and dedicated cloud offerings. The Open Source Server org works on core Temporal.

What You’ll Do

• Design and implement core backend service features for Nexus
• Provide appropriate test coverage for unit, integration, and performance for your feature ownership area.
• Clearly document design choices and operational knowledge to successfully deploy and run service with those features.
• Provide appropriate service level logs and metrics to make features operational for cloud service setup.
• Provide appropriate alerts, dashboards, and runbooks for production.

What You Won’t Do

• Work in an office (unless you want to, but you’d be by yourself). Temporal is a fully‑remote company.
• Commit code that’s poorly‑tested or works “most of the time”. Temporal aspires to be “Reliable as Gravity”, and we expect your code to be the same.
• Work behind closed doors. The SDKs are open source—that means PRs and comments are open to the public, too.
• Sit in meetings all day. We mostly communicate in writing, and use meetings mainly for status updates and thorny issues that need input from the whole group.

What You’ll Bring

• At least 6 years of experience in a production environment as an "Arranger" and/or "Builder/Enhancer" of highly scalable distributed systems. see HERE for more info re: "Arranger" and/or "Builder/Enhancer"
• Solid computer science fundamentals in distributed systems concepts including multi‑threading and concurrency.
• 2+ years experience developing customer facing APIs and Frameworks
• 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. see HERE for more info re: "high end of Intermediate" and/or "Advanced" or "Expert levels"

Compensation

• The estimated pay range for this role is $185,000 - $225,000 depending on locale.
• Additionally, this role is eligible to participate in Temporal’s equity plan.
