About Datadog We're on a mission to build the best platform in the world for engineers to understand and scale their systems, applications, and teams. We operate at high scale with trillions of data points per day, enabling seamless collaboration and problem-solving among Dev, Ops, and Security teams for tens of thousands of companies globally. Our engineering culture values pragmatism, honesty, and simplicity to solve hard problems the right way. The Team The Datadog Security Libraries team owns the customer-side integrations behind our run-time security products App & API Protection , Workload Protection , and Code Security . Our libraries let customers automatically manage application security risk with continuous, real-time monitoring of vulnerabilities and threats against their web applications, serverless applications, and APIs, in production. Automatically integrated with Application Performance Monitoring (APM) distributed tracing and code-level context, our software empowers development, operations, and security teams to build and run secure applications. As a polyglot team we ship and maintain the security capabilities of Datadog's tracing libraries across .NET , Java , Go , Node.js , Python , Ruby , and PHP , on top of a shared C++ core and a set of HTTP proxy integrations (primarily Envoy, NGINX, and HAProxy). Our code runs inside thousands of production applications around the world. Recent work spans exploit prevention (RASP) and WAF detections, API Security, code security (IAST and SCA), and AI-assisted ("agentic") onboarding, always measured by real product outcomes and operational telemetry. The Opportunity We're looking for a senior, polyglot engineer to contribute across several of our security libraries, with .NET or Java expertise. You'll design and build security integrations and detection features, take them from prototype to production-hardened, and own them operationally as they instrument thousands of applications. As a se

About the Role & Team We’re looking for an Engineering Manager to lead the Delivery and SDK team within Statsig at Amplitude. This team builds the systems that connect developers to Statsig and safely deliver product experiences to end users around the world. The team owns two foundational areas: Delivery: The globally distributed systems that evaluate Experiments and Feature Gates and deliver the resulting experiences to end users. These systems sit directly in the critical path of our customers’ applications, making availability, scale, correctness, and latency essential. SDKs: More than 30 SDKs spanning web, mobile, server, edge, TV, gaming, and emerging platforms. Our goal is to meet developers wherever they build and give them an ergonomic, reliable way to integrate Statsig into any application or technology stack. This is a uniquely broad technical leadership role. You’ll work across distributed systems, mobile platforms, server runtimes, edge environments, and developer tooling—sometimes all in the same week. We’re looking for a hands-on, technically versatile leader who enjoys moving between technologies, learning unfamiliar systems, and solving problems across abstraction boundaries. You don’t need to be the world’s foremost expert in a single language or platform. You do need the curiosity and technical judgment to work effectively across many of them—and the ability to build a team that can make a complex, polyglot ecosystem feel simple and dependable to developers. What You’ll Do Lead and grow the team responsible for Statsig’s global delivery infrastructure and ecosystem of 30+ SDKs. Leading a team of 8-10 team members Define the technical strategy for highly available, low-latency evaluation and delivery systems operating at global scale. Make Statsig exceptionally easy to adopt by continuously improving SDK ergonomics, performance, reliability, consistency, and documentation. Expand our SDK coverage as new languages, frameworks, runtimes, and comp

About the Team API Agents builds the shared agent harness, tools, and infrastructure that turn OpenAI’s frontier models into systems that can reliably complete real work. We carry the capabilities behind Codex into a much broader set of products and workflows across software engineering, research, finance, healthcare, enterprise operations, and more. Our work spans search and connected context, computer use, memory, delegation and multi-agent coordination, and safe execution. Sitting at the intersection of Research, Codex, infrastructure, and applied product teams, we build reusable agent capabilities that compound across the ecosystem. About the Role We are looking for an experienced backend software engineer to build the core systems behind the next generation of agents. You will design reliable services and abstractions that help agents find the right context, use tools and computers, retain knowledge, coordinate over long-running workflows, and take action safely. The role combines deep backend and infrastructure work with strong product judgment, with opportunities to work across agent runtimes, orchestration, search, execution environments, identity and permissions, observability, and evaluations. This is software and systems engineering rather than model training: success comes from strong backend fundamentals, high agency, and the ability to turn fast-moving research capabilities into dependable production primitives. In this role, you will: Design, build, and operate the shared agent harness and backend infrastructure that power long-running, high-value workflows across OpenAI and third-party products. Build reusable capabilities across search and connected context, computer use, memory, tool execution, delegation, subagents, and multi-agent orchestration.

This role is ideal for someone who thrives in async, fast-paced environments and is excited about building developer tools that scale to millions. What You'll Be Responsible For Build and evolve our JavaScript/TypeScript SDKs. Start new things. Alongside the maintenance work, you're expected to find what's missing, make the case for it, and build it. Some of what we ship next doesn't exist yet, and nobody will hand you the list. Work in the open. These are public repos: you'll triage inbound issues, review and shepherd outside contributions, keep CI and release automation healthy, and hold a clear, kind line on scope. Own the type experience. Keep generated database types flowing correctly through the client APIs so autocomplete and inference stay correct in real codebases. Keep us honest across runtimes.
