Staff Forward Deployed Engineer, Feature Flags

As a Forward Deployed Engineer on the Feature Flags team, you'll partner directly with customers to accelerate their feature flag implementations — from initial architecture consulting through prototype builds to full-scale migrations. This role is for someone who wants to write code with customers, not just advise them. You'll work hands-on inside customer codebases to unblock complex, high-stakes deployments, directly influencing deal velocity and customer success. Working closely with Sales, Solutions, and Engineering, you'll be the technical force that turns a signed contract into a live, adopted implementation.

What You'll Do:

• Serve as the hands-on technical partner for strategic customers implementing Datadog Feature Flags, from pre-sales technical validation through post-sales delivery

• Consult on flag architecture and implementation approach for complex environments — multi-service, multi-platform, high-scale deployments

• Build prototype flag implementations directly in customer codebases to prove value and de-risk technical decisions early in the sales cycle

• Implement flags across diverse and advanced deployment modes (server-side, client-side, edge, mobile, streaming/real-time) tailored to each customer's stack

• Drive full flag migrations to completion — including legacy system cutover — efficiently and with minimal customer engineering burden

• Identify patterns across customer implementations and feed them back to Product and Engineering to improve the core product and reduce future implementation time

• Collaborate closely with Engineering on technical edge cases, product gaps, and implementation tooling

• Partner with Sales and Solutions to accelerate deal cycles by removing technical risk and uncertainty

Who You Are:

• 5 years of professional software engineering experience, with hands-on coding ability across the sta
