Senior Product Designer, Growth

About the Job:

The Foundation team's mission is to make LaunchDarkly the tool that every new startup and small engineering team wants to use. That means owning the moments that determine whether a developer evaluating LaunchDarkly becomes a customer: the trial experience, the SDK integration path, the first time they see a feature flag work in their own code, and the point where they understand what they're actually paying for.

Developers are a demanding audience. They don't tolerate setup friction, opaque pricing, or products that require a sales call to understand. The activation and trial experience for a developer tool has to earn attention quickly and deliver real value before asking for commitment. Designing that well across the signup flow, SDK integration, in-product onboarding, and first engagement with advanced valuable features like experiments and guarded releases is the core design challenge here.

The team works from a documented evidence base: customer feedback analysis, funnel data, and recorded sales calls. The problems on the roadmap are grounded in that evidence, each with a defined hypothesis and a target metric. There's also a newer design problem: the team believes AI agents will become a primary developer onboarding channel, and building that experience is active roadmap work. It is an incredibly exciting place for a designer to play.

This role calls for someone with a growth background (activation funnels, conversion experiments, behavioral design), not a generalist product design scope.

Responsibilities:

• Design the Foundation trial and activation experience from signup through SDK integration, first flag, first advanced feature, and conversion to a paid plan.
• Work from the team's evidence base — customer insights data, product analytics funnel analysis, sales and support call patterns — and add to it with your own research. Run experiments against that evidence on cycle times measured in weeks.
• When you find drop-offs, trace them to their structural cause: wrong information architecture, missing context, an illegible value proposition. The fix belongs upstream, not just at the symptom.
• Design the agentic onboarding experience: what getting started with LaunchDarkly looks like when the interface is an MCP, a Skill and an AI coding agent rather than a browser. The team has a working thesis and active PRDs; the UX is open and exciting.
• Improve advanced feature discoverability. Experiments and guarded releases are significantly underused relative to their value, and closing that gap requires working across team boundaries.
• Contribute to roadmap decisions alongside your product manager and engineering manager peers, bringing activation opportunities forward with data rather than waiting to be briefed.
• Participate in UX critique and expect direct, specific feedback in both directions.
