Fullstack Engineer, Error Monitoring

Hybrid - US

About the Job: 

LaunchDarkly is looking for an experienced Fullstack Engineer to play a key role in building a new product line on the Error Monitoring & Session Replay team. You’ll be part of the Release Observability pillar, which is focused on making every release safer, faster, and more reliable. Our mission is to redefine how software is released: automating release processes, measuring the real-time impact of feature rollouts, and simplifying debugging when things go wrong. From automated release pipelines to metrics monitoring, error tracking, and fully automated rollbacks, our work ensures every code change is measured, and the entire release process from rollout to issue mitigation is managed for maximum efficiency and reliability.

As a member of Error Monitoring & Session Replay team, you’ll be helping us harness the power of LaunchDarkly’s SDKs to automatically track errors in customers' applications, aggregate them to measure user impact, and use them to make smart decisions about releases.

If you’re interested in building the systems that help software teams ship safely at scale, we’d love to work with you.

Responsibilities:

  • Collaborate seamlessly with cross-functional partners (product, design, data science, and engineering) to architect and advance our error monitoring and session replay products. Leverage your broad experience to facilitate strategic discussions that align technical solutions with business goals, ensuring the delivery of scalable and effective features.

  • Drive comprehensive end-to-end feature development, taking full ownership from proof of concept through to delivery. Ensure that each feature provides robust observability into system behavior and customer usage patterns post-launch, applying a deep understanding of both technical and user experience considerations to optimize feature performance and reliability.

  • Proactively identify opportunities for product and user experience improvements, leveraging data insights and feedback to propose innovative, well-reasoned solutions. Lead the implementation of these enhancements, balancing user needs, business goals, and technical feasibility, ensuring each change drives meaningful improvements in engagement and performance.

  • Provide expert mentorship and support to teammates, guiding them through complex challenges and fostering a collaborative, high-performance environment. Your deep expertise will help accelerate their growth, elevate team standards, and enhance overall productivity and technical excellence.

  • Actively lead and contribute to code reviews, spec reviews, and architecture design, ensuring alignment with best practices, long-term scalability, and maintainability. Your experience will drive thorough and thoughtful evaluation of solutions, while providing constructive feedback that elevates the quality of the codebase.

  • Play a key role in advancing engineering standards, tooling, and processes across the technology organization. By identifying areas for improvement and implementing process innovations, you will shape a more efficient and effective development environment, empowering teams to deliver high-quality features faster.

Qualifications:

  • 5+ years of software development experience with a focus on fullstack development, or equivalent demonstrable skills and experience.

  • Extensive experience with server-side programming languages (e.g. in Golang, Java, Ruby, Python)

  • Proficiency with modern JavaScript libraries and tooling, such as React.

  • Proficient in designing, implementing, and maintaining RESTful APIs

  • Experience working directly with customers and understands how their work impacts business goals

  • Strong sense of ownership and accountability for delivering impactful solutions

  • Proven ability to work closely and collaborate with cross functional partners, like product and design

  • Experience working with data products or closely with data science counterparts (e.g. experimentation, data ingestion, data analysis)

  • Committed to writing maintainable, easily understandable code while upholding high standards for production systems

  • Strong understanding of observability and monitoring tools and practices.

  • Excellent communication, collaboration, and interpersonal skills.

  • A proactive and self-directed approach to work.

  • Experience in a fast-paced, dynamic environment.

  • Experience working with distributed teams.

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

At LaunchDarkly, we believe in the power of teams. We're building a team that is humble, open, collaborative, respectful and kind. We are an equal opportunity employer and value diversity at our company. We do not discriminate on the basis of race, religion, color, national origin, gender, gender identity, sexual orientation, age, marital status, veteran status, or disability status.

A "recently separated veteran" means any veteran during the three-year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service.

An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense.

An "Armed forces service medal veteran" means a veteran who, while serving on active duty in the U.S. military, ground, naval or air service, participated in a United States military operation for which an Armed Forces service medal was awarded pursuant to Executive Order 12985.

Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
