Backend Engineer (Multiple Positions) at LaunchDarkly
- Remote.
Backend Engineer About LaunchDarkly Engineering LaunchDarkly helps engineering organizations ship software and AI with speed, safety, and control. Our platform gives teams the confidence to release gradually, target experiences to the right audiences, learn through experimentation, understand what is happening in production, and respond quickly when risk appears. Our engineers build the systems, services, SDKs, developer tools, cloud infrastructure, and product experiences that make this possible. The work spans high-scale distributed systems, reliable data and event pipelines, intuitive enterprise workflows, and AI-powered capabilities that help teams manage the next generation of software delivery. LaunchDarkly’s SDKs are used in systems that perform trillions of feature flag evaluations each day, giving our engineering work a direct connection to the reliability and customer experience of software around the world. As the company grows, we are expanding beyond traditional feature management into experimentation, observability, and AgentControl—helping customers control more of the software and AI lifecycle. That creates an unusually broad set of technical challenges, visible customer impact, and room for engineers to shape what comes next. We believe in the power of teams. We work with humility, openness, curiosity, and care; we value clear communication, thoughtful technical judgment, inclusive collaboration, and a strong sense of ownership. We encourage people to apply even when they do not meet every qualification listed below. We are interested in the experience, perspective, and potential you would bring to the role. About the role We have multiple backend engineering roles open on various teams. The specific level, scope, and technical focus will be aligned to the opportunity and the candidate’s experience. Experience with cloud platforms, distributed systems, developer tools, SDK engineering, data infrastructure, observability, or AI/agent systems may be relevant for some teams.

What you’ll do Design, implement, test, and operate production services and APIs. Lead projects or meaningful components of projects from problem definition through deployment and iteration. Make thoughtful tradeoffs across scalability, performance, reliability, security, maintainability, and delivery speed. Improve the observability and operability of the systems you own, including metrics, logs, traces, alerting, and incident learnings. Collaborate with Product, Design, Support, Customer Success, and other engineering teams to understand needs and deliver useful outcomes. Participate in technical design discussions and code reviews, sharing constructive feedback and learning from teammates. Investigate production issues calmly and help turn operational lessons into lasting improvements. Contribute to a culture of inclusive collaboration, continuous improvement, and high-quality engineering. Qualifications 5+ years of experience building and operating production software in a professional environment, or equivalent demonstrable experience.
