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.

Senior Backend Engineer

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.

Candidates may be considered for opportunities across product engineering, core engineering, feature management, observability, experimentation, data platform, cloud infrastructure, SDKs, and AI/agent product areas, depending on experience, interests, and business need.

As a Senior Backend Engineer at LaunchDarkly, you will design, build, and operate the services that power reliable software delivery for our customers. You may work on APIs, distributed systems, configuration and event pipelines, data services, SDK-related infrastructure, platform capabilities, or backend systems supporting our product experiences.

You will take ownership of complex, high-impact work from problem definition through production and iteration. You will partner with Product, Design, Staff Engineers, Engineering Managers, and adjacent teams to turn customer and business needs into simple, scalable solutions. Your work will influence technical direction within your team and, where appropriate, across team boundaries.

What You’ll Do

• Lead the design and delivery of large or ambiguous backend projects, breaking them into clear milestones and creating alignment with partners.
• Design, implement, test, and operate production services and APIs that are scalable, secure, observable, and maintainable.
• Make and communicate thoughtful tradeoffs across scalability, performance, reliability, security, maintainability, cost, and delivery speed.
• Identify architectural risks, performance bottlenecks, operational gaps, and sources of technical friction; then drive durable improvements.
• Improve the observability and operability of the systems you own, including metrics, logs, traces, alerting, service-level objectives, and incident follow-through.
• Collaborate with Product, Design, Support, Customer Success, and other engineering teams to understand needs and deliver measurable customer outcomes.
• Influence technical direction through design documents, architecture discussions, code reviews, and clear written and verbal communication.
• Mentor engineers, raise the quality of technical decision-making, and contribute to a culture of inclusive collaboration and continuous improvement.
• Participate in production support and incident response with calm ownership, turning operational lessons into lasting improvements.
• Help evolve engineering practices, reusable patterns, and developer experiences that make other teams more effective.

Qualifications

• 7+ years of experience building and operating production software, with a track record of delivering meaningful customer or business impact.
• Strong software engineering fundamentals, including data structures, algorithms, testing, debugging, API design, and distributed-systems concepts.
• Deep experience with a backend language such as Go, Python, Rust, or an equivalent language. (Most of our teams use Go)
• Experience designing systems that must remain reliable, observable, secure, and maintainable as usage, complexity, and team ownership grow.
• Demonstrated ability to lead technical projects with ambiguous requirements, multiple stakeholders, or cross-team dependencies.
• Sound judgment when evaluating architecture, technology choices, operational risk, and short- versus long-term tradeoffs.
• Ability to explain complex technical decisions clearly and build alignment with technical and non-technical partners.
• Experience mentoring engineers and strengthening team practices through feedback, documentation, pairing, or technical leadership.
• A strong sense of ownership for production outcomes and downstream customer impact.
• Comfort learning unfamiliar systems and navigating changing priorities with curiosity and a collaborative mindset.

About LaunchDarkly

Modern software delivery was supposed to be the foundation for a thriving digital business but reality has proven otherwise. Slow, inefficient development cycles, costly outages, and fragmented customer experiences are preventing developers from building their best software. The LaunchDarkly platform helps developers innovate on new features faster while protecting them with a safety valve to instantly rewind when things go wrong. Developers can target product experiences to any customer segment and maximize the business impact of every feature. And by gradually rolling out new application components, they escape nightmare "big-bang" technology migrations.

The LaunchDarkly platform was built to guide engineers to the next frontier of DevOps by:

• Improving the velocity and stability of software releases, without the fear of end customer outages
• Delivering targeted experiences by easily personalizing features to customer cohorts
• Maximizing the business impact of every feature through the ability to experiment and optimize
• Coordinating the release and optimization of software to provide consistent experiences across mobile platforms and device types
• Improving the effectiveness and productivity of engineering teams, by providing insights into engineering cadence and stability
