Datadog is a comprehensive observability and security platform that provides integrated monitoring for infrastructure, applications, and cloud services. It enables organizations to gain end-to-end visibility into their technology stacks, optimize performance, and manage security threats in real time. Datadog's solutions include application performance monitoring, logs management, and operational analytics, making it essential for teams looking to improve their digital experience and streamline software delivery processes.

📋 Description

• Design, build, and own security integrations and detections (WAF, RASP/exploit prevention, API Security, IAST, SCA) across multiple libraries, with .NET and/or Java as your primary focus. • Take projects from prototype to deployed, correct, operable, and maintainable, writing code that safely instruments thousands of applications in production. • Own your systems operationally: monitor production telemetry (e.g., WAF/RASP timeouts, performance and cost), debug challenging cross-system issues, and drive down customer-facing problems. • Shape the roadmap: help define the OKRs for the systems you own, break features into components other engineers can build in parallel, and drive designs and RFCs to alignment across our security library teams. • Partner with product management, backend, and frontend teams to turn product ideas, new detections, agentic onboarding, API security, into capabilities customers actually adopt. • Mentor teammates and act as a force multiplier: raise the bar on code quality and testing, and make the whole team more effective than you'd be on your own. • Represent Datadog in the relevant language and security communities.

🎯 Requirements

• You are an expert in at least one of .NET (C#) or Java, and you're a polyglot who can contribute idiomatically across other libraries when needed with the support of their main maintainers. For each language you use, you write clean, correct, well-tested, performant, idiomatic code. • You have strong software-engineering fundamentals: you consistently ship modular, maintainable code with little guidance, and you leave code in substantially better shape than you found it. • You have a product-engineering mindset: you care about user experience and product outcomes as much as the code, weigh technical trade-offs against customer impact, and help decide what to build, not just how. • You have experience building and shipping libraries or SDKs consumed by other developers, and you understand packaging, versioning, and backward compatibility. • You care about performance and cost, in both time and space, and you have experience measuring and optimizing to that end. • You are operationally mature: you take full accountability for what you ship in production, even when others work on it. • You communicate clearly in writing and in person, you drive alignment through RFCs and informal collaboration, give bad news early, and give constructive, empathetic feedback to peers. • You have a BS/MS/PhD in a STEM field or equivalent experience.
