What are the key skills and qualifications needed to thrive as an Open Source Developer, and why are they important?

To thrive as an Open Source Developer, you need strong programming skills, familiarity with version control systems like Git, and experience contributing to or maintaining open source projects. Proficiency with platforms such as GitHub, bug tracking systems, and knowledge of relevant programming languages (e.g., Python, JavaScript) are typically required. Excellent communication, collaboration, and self-motivation are crucial soft skills, as much of the work involves distributed teams and community interaction. These skills ensure effective project contributions, sustained community engagement, and the successful growth of open source initiatives.

What Does an Open Source Developer Do?

As an open source developer, you work with open source code, tweaking, improving, and building upon it to create new software for an organization. Your duties vary depending on the position, but they can include using your knowledge of various open source coding systems and software to code new programs and applications, troubleshooting and debugging software, and tracking and reporting issues. Your responsibilities also include researching and learning about current and new standards for the coding languages with which you work. Most open source developers have skills and expertise in multiple programming languages, but many organizations are willing to train quick learners on each project.

What is an Open Source Developer?

An Open Source Developer is a software professional who creates, maintains, or contributes to software projects whose source code is freely available to the public. These developers collaborate with others in online communities, often working on projects hosted on platforms like GitHub or GitLab. Their work involves writing code, fixing bugs, reviewing pull requests, and documenting software. Open Source Developers help improve software that anyone can use, modify, or distribute, fostering innovation and collective problem-solving.

How does an Open Source Developer typically collaborate with a global, distributed team?

Open Source Developers often work with contributors from around the world, which means collaboration takes place primarily through online platforms such as GitHub, mailing lists, and chat tools like Slack or Discord. Communication is usually asynchronous due to time zone differences, so clear documentation and issue tracking are essential. Developers regularly review and comment on each other's code, participate in discussions about project direction, and sometimes join virtual meetings or code sprints. This environment encourages learning from diverse perspectives and requires strong written communication and self-motivation.

What is the difference between Open Source Developer vs Software Engineer?

Employer & Industry UsageOpen source projects, tech companies, startupsTech firms, software companies, enterprises
Common Search & ComparisonOften compared for coding skills and community involvementCompared for project management and product development roles

Open Source Developers focus on contributing to publicly available projects, often working in collaborative communities. Software Engineers design, develop, and maintain software products within organizations. While both require programming skills and a background in computer science, Open Source Developers emphasize community collaboration and open contributions, whereas Software Engineers typically work within structured teams on proprietary or client projects.

Job description

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
Temporal is looking for a Senior Staff Engineer to join the Open Source Server team as a technical lead.
This team works on the core Temporal server. Its scope is broad, including Matching, Applications, Foundations, task processing, quotas and throttling, visibility, developer-facing primitives such as standalone activities, schedules, and streaming, and workflow experience improvements such as Continue-As-New, pause, and reset.
We do not expect one person to cover all of these areas. We are looking for someone who can come in, learn the system, find where they can have the most impact, and lead from there.
This is a hands-on technical leadership role. You will help set direction, design and build important parts of the server, mentor other engineers, and improve the reliability, performance, operability, and developer experience of Temporal.
What You'll Do
  • Lead the design and implementation of important server features, from proposal through rollout.
  • Help set technical direction for one or more areas of the OSS Server team.
  • Work on distributed systems problems across areas such as task matching, scheduling, workflow execution, visibility, quotas, throttling, persistence, developer primitives, and workflow lifecycle features.
  • Make practical tradeoffs across reliability, performance, operability, product needs, and open source usability.
  • Partner with engineers, product managers, cloud teams, and customer-facing teams to turn hard problems into clear technical plans.
  • Improve how we build and run the server through better testing, observability, dashboards, alerts, runbooks, and documentation.
  • Review designs and code, mentor engineers, and help the team make good technical decisions.

What You'll Bring
  • 12+ years of experience building and operating production distributed systems.
  • Strong technical leadership experience, including leading design work, aligning engineers, and driving complex projects to completion.
  • Strong fundamentals in distributed systems, concurrency, fault tolerance, scheduling, and performance.
  • Production experience with Go, Java, or a similar backend language.
  • Experience with high-scale or performance-critical systems, such as request serving paths, task queues, scheduling systems, streaming or replication pipelines, rate limiting, sharding, load balancing, workflow engines, or orchestration systems.
  • Good operational instincts. You care about reliability, observability, debugging, incident response, and making systems easier to run.
  • Experience designing APIs, primitives, or platform features that other developers use.
  • Experience working with open source systems or communities.
  • Experience with cloud infrastructure on AWS, Azure or GCP experience is a plus.
  • Experience with systems such as Elasticsearch, OpenSearch, ClickHouse, Cassandra, PostgreSQL, or MySQL is a plus.
  • Experience with Kubernetes controllers, CRDs, KEDA, or Argo is a plus.
What Makes You a Good Fit
  • You like working on deep systems problems, but you also care about the people who have to use and operate the system.
  • You are comfortable joining a large codebase, building context, and finding the right place to make an impact.
  • You do not need to know Temporal already, but you should be excited to work on the core of a distributed system used by a large open source community and enterprise customers.

Compensation
  • The estimated pay range for this role is $260,000 - $325,000 depending on experience and location.
  • Additionally, this role is eligible to participate in Temporal's equity plan.

Compensation ranges reflect salary and commission compensation (when applicable) across several geographic markets. Employment offers carefully consider multiple factors, including prior experience, knowledge, expertise, skillset, market location, and job level assessed during the interview process.
Employee benefits and perks below are for full-time employees, part-time or temporary positions are excluded.
U.S. Benefits
  • Unlimited PTO, 12 Holidays + 2 Floating Holidays
  • 100% Premiums 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!

Additionally, Temporal offers perks to all international employees for learning & career development, a lifestyle spending account, in-home office setup (in addition to company-issued hardware), professional memberships, work-from-home meals, and access to the Calm app for mental wellness.
