LaunchDarkly is looking for an experienced Backend Engineer to join our Observability team, delivering best-in-class telemetry to help engineers monitor, analyze, and debug their applications in real time. Our mission is to redefine software release and reliability by automating end-to-end processes, measuring the real-time impact of feature rollouts, and simplifying incident diagnosis when things go wrong. From code-level tracing to browser user journeys, these signals form the backbone of safe, data-driven releases. You’ll help shape the foundation of how our customers understand and optimize their feature rollouts, building systems that are performant, reliable, and easy to operate at massive scale.
Our work spans everything from collecting raw telemetry to transforming and enriching it, storing it cost-effectively, and exposing high-fidelity metrics and visualizations. You’ll partner closely with product teams to ensure we’re delivering insights that matter, all while helping scale our data ingestion pipeline to handle trillions of events per day.
If you’re passionate about observability, distributed systems, and empowering engineering teams with real-time data at massive scale, we’d love to have you join us.
Responsibilities:Build out the next-generation ingestion pipeline for OpenTelemetry metrics, traces, and logs, capable of processing high throughput with low latency.
Tune and optimize distributed data systems (e.g., Kafka, ClickHouse) to ensure resilience, throughput, and cost-efficiency.
Drive features from conception through production: write prototypes, define APIs, build robust services, and validate correctness in production.
Collaborate on OpenTelemetry SDK enhancements to help customers emit the right signals.
Work hand-in-hand with product managers, UX designers, and frontend engineers to deliver customer-facing metrics capabilities.
Actively mentor and support colleagues across the organization
Actively participate in code reviews, spec reviews, and architecture design
Contribute to the improvement of engineering standards, tooling, and processes across the technology organization.
5+ years of Application Backend Software Engineering experience
Experience with server-side programming languages (e.g. Go, Node.js, Python)
Understanding of data pipelines, message brokers (e.g., Kafka), and storage engines (e.g. ClickHouse).
Experience using AI tooling to accelerate daily software development (e.g. Cursor, Devin, Glean). Familiarity with frontend prototyping tools (v0, Lovable, Bolt) is a plus, especially in the context of full-stack web development.
Hands-on experience with OpenTelemetry or other observability frameworks, including metric aggregation, tracing, and log collection.
Proven track record of designing and maintaining GraphQL or RESTful or APIs that serve thousands of requests per second.
Familiar with capacity planning, horizontal scaling, performance tuning, and production-grade reliability practices.
Strong grasp of algorithms, data structures, concurrency, and distributed consensus.
Excellent communication skills, with a passion for partnering across functions to solve complex problems.
Self-driven, curious about emerging observability technologies, and committed to continuous learning and improvement.

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
