Senior Software Engineer, Backend - Reliability

Camunda is an enterprise platform for agentic orchestration that helps organizations coordinate AI agents, people, and systems across complex business processes. The Senior Software Engineer, Backend - Reliability will own automated reliability testing and chaos engineering for Camunda 8, investigate failures and performance regressions, improve testing and observability infrastructure, and collaborate with engineering and QA teams to strengthen platform reliability.

Responsibilities:

• Design, implement, and execute automated chaos experiments and reliability tests, validating Camunda's platform under real-world scenarios
• You will investigate, root-cause and debug potential failures or performance regressions of our Java based products
• Continuously improve existing load testing, chaos engineering and observability infrastructure to keep our system reliable and performant
• Here we use different languages, tools and frameworks like java, go, kubernetes, prometheus, grafana, etc
• Introduce new tooling and approaches for reliability testing, driving measurable improvements to operational experience and user outcomes (examples from the past: introducing zbchaos as fault injection tool)
• Collaborate closely with QA and engineering (including cross-functional teams), sharing learnings (e.g. with our team blog) and influencing team roadmaps based on experiment findings
• Champion a pragmatic, autonomous approach to software design, solving tough problems and learning new principles and technologies (Kubernetes, Helm, Grafana, Java, Go, and more)
• Advocate for user-centric reliability by using and understanding Camunda’s products firsthand
• Based on all of the above, you have end to end delivered a concrete task, as for example (the concrete goal will be defined during your onboarding):
• After 3 months, you have designed and delivered a way to run quick and reproducible load tests, allowing us:
• To reduce the feedback loops for engineers
• Directly fitting into the development lifecycle
• Enable engineers to make use of it and extend it
• After 3 months, you have designed and implemented a realistic, automated, holistic load testing framework for Optimize, in close collaboration with Senior Engineers and Field teams:
• Conducted a deep-dive analysis of performance limits
• Shared results with the relevant core engineering teams and enabled them to re-run the tests
• Documented findings in public-facing documentation to help users better understand performance characteristics and guide their installation design

Requirements:

• • Ability and/or willingness to use our product
• • 5+ years of experience in backend software engineering (Java)
• • Proven drive to experiment, learn new tech, and conduct automated reliability and chaos testing in distributed environments
• • Deep enthusiasm for improving performance and fault-tolerance in production systems
• • Autonomous, pragmatic problem-solving skills with an ability to guide and influence others
• • Willingness and ability to use Camunda products and approach reliability from a user's perspective
• • Hands-on experience with Go or other languages, in a multi-language context
• • Working as SRE on distributed systems, with a strong software engineering mindset before
• • Working knowledge of Kubernetes, Helm Charts, Operators, and related production infrastructure
• • Experience running apps in production, with solid skills in monitoring, troubleshooting, and performance analysis
• • Background in chaos engineering, automated reliability, load, or performance testing
