About the Job: As a Backend Engineer on LaunchDarkly’s AI Configs team, you’ll build critical systems such as the web application that customers interact with on a daily basis and distributed systems that power AI evaluations at scale. These systems enable customers to control, monitor, and optimize their GenAI functionality. You’ll primarily work in Go and Python, and will work directly with other technologies and tools such as AWS, CockroachDB, and Datadog.
LaunchDarkly’s AI Configs team is on a mission to manage the complete software development lifecycle for GenAI features, from configuring to benchmarking to observing and beyond. This team has a huge opportunity ahead of it; we’re growing fast and we need your help writing the next chapter in our story.

Participate in architecture and design discussions, offering thoughtful input and collaborating with senior engineers to identify tradeoffs and make well-informed decisions
Keep up-to-date with the latest developments in the AI field and in software development best practices
Take ownership of code in production, participate in on-call rotations, and help improve the reliability and maintainability of our systems over time.
Qualifications:
2 years of experience with server-side programming languages (e.g. in Java / Scala, Ruby, Python, Golang)
Hands‑on experience building GenAI features or working with Large Language Models (LLMs), either through direct model integration or leveraging AI APIs like OpenAI, Google Cloud AI, or AWS Bedrock.
Understanding of prompt engineering, fine‑tuning models, or deploying AI services in production environments.
Experience with designing, implementing, and maintaining RESTful APIs
Experience writing production‑ready code with emphasis on quality and maintainability
Experience with distributed systems or data ingestion
Strong computer science fundamentals
Committed to working in a communicative, collaborative environment
Comfortable navigating ambiguous challenges in a rapidly evolving domain, and excited about staying at the forefront of AI advancements
Strong sense of ownership and accountability for delivering impactful solutions
Proven ability to work closely with Product and Design teams to define requirements for new features in a fast‑paced iterative environment

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. LD invites any applicant to review our written Aff and you can contact People Ops at hr@launchdarkly.com.
