Senior Staff Engineer, Open Source Server

Location: United States (Remote) Workplace: Remote ROLE 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.
