Role
Who you are
- 1-3 years of experience working with JavaScript (front-end and back-end) and related frameworks (e.g., React, Node.js), ideally working on libraries, SDKs, or developer tools in JavaScript
- Familiarity with TypeScript and a willingness to learn other programming languages
- Basic understanding of computer science fundamentals
- Experience or interest in building libraries, packages, or tools for other developers
- Commitment to quality through testing and maintaining well-documented, maintainable code

What the job involves
- As a Software Engineer on LaunchDarkly’s SDK team, you will contribute to the primary touchpoints our customers interact with daily
- You’ll work on multiple technologies across our 20+ SDKs, helping enable customers of all kinds to feature-flag their code
- Our SDKs are more than simple client wrappers—they are feature-rich agents designed for performance, concurrency, and resiliency, all while adhering to idiomatic practices for their respective tech stacks
- LaunchDarkly serves trillions of feature flags daily to customers all around the globe, and every flag is handled by our SDKs
- Joining this team gives you the opportunity to grow your skills while having a meaningful impact on our product and our customers
- Contribute to the development and maintenance of LaunchDarkly’s JavaScript-based SDKs (e.g., Node Server, React) and other supported platforms
- Assist in ensuring LaunchDarkly’s SDKs remain aligned with modern JavaScript development practices and trends
- Collaborate with the team to identify areas for improvement and implement enhancements to SDK functionality and performance
- Participate in cross-team collaboration with engineering and product teams to help deliver new features
- Work with open-source repositories, including contributing to and maintaining documentation and code quality
- Support testing efforts by writing and maintaining unit, integration, and performance tests
- Learn and grow by engaging with feedback and mentoring opportunities
Our take
Feature flags are a powerful software development tool, allowing teams to modify system behavior without changing code, therefore minimizing risk. If a business has a new feature they want to test, they can then roll it out to a small set of users before letting it go live. These companies can, for example, get quick feedback on the new feature and fix any bugs, or roll back any changes.
LaunchDarkly allows companies to run tests like this by activating the new code for only a small set of users prior to launch. Typically running these tests requires lots of developer time - a daunting and expensive prospect for most rapidly growing businesses - and can risk disruption to the user experience if testing takes place on the live product.
The platform is used by more than 1,500 customers, including the likes of IBM, Intuit and Atlassian. Signalling a change in strategy, the company shook up its management in 2023 and is now aiming to scale its already strong growth under the leadership of Dan Rogers, a product and marketing specialist with an impressive track record at Rubrik, AWS and Microsoft. It is now well poised to develop into a leading business in the feature management space.
