Required

5 years of professional software engineering experience, with hands-on coding ability across the stack you're deployed into
Experience with feature flagging, experimentation, or config management systems (internal or vendor)
Comfortable dropping into unfamiliar codebases, languages, and frameworks quickly — no specific stack required, but strong fundamentals and fast ramp-up
Experience shipping production code, not just prototypes — you understand the difference between a demo and something that survives a migration
Customer-facing experience, or strong motivation to build it — comfortable being in the room with customer engineers, understanding their constraints, and adapting your approach
Skilled at simplifying complex technical tradeoffs for both engineering and non-engineering stakeholders
Motivated by outcomes — deal velocity, successful migrations, and customer trust — not just elegant code
Comfortable operating with ambiguity, moving between architecture conversations and hands-on implementation in the same week

Preferred

Experience in a forward-deployed, consulting, or professional services engineering role
Exposure to large-scale system migrations
Prior work in a startup or fast-scaling environment where you had to own ambiguous problems end-to-end
This team built Eppo — the market-leading experimentation and feature flagging platform trusted by companies like Coinbase, Perplexity, and DraftKings — and joined Datadog through its acquisition. Feature Flags sits at the center of that suite that includes experimentation, product analytics, session replay, RUM, and synthetics. As a Forward Deployed Engineer, you'll work directly inside customer codebases to make that loop real — turning flag architecture decisions into shipped, adopted implementations, and helping our most strategic customers build flag-driven development as a core engineering capability.
This role is based in New York City and works closely with Engineering on a regular basis.
