Lisbon, Portugal

Datadog’s Feature Flags team builds tools that help customers control application behavior, reduce deployment risk, and power advanced experimentation. Our work spans multiple languages and platforms, leveraging a shared Rust-based core and OpenFeature integrations to ensure performance and reliability at scale. We operate with the speed and innovation of a growth-stage startup, bolstered by Datadog’s acquisition of Eppo. As a Senior Software Engineer, you’ll help shape the future of our experimentation platform, working across systems where correctness, global distribution, and low‑latency performance are critical.
