Every day, tens of millions of people come to Roblox to explore, create, play, learn, and connect with friends in 3D immersive digital experiences– all created by our global community of developers and creators. At Roblox, we’re building the tools and platform that empower our community to bring any experience that they can imagine to life. Our vision is to reimagine the way people come together, from anywhere in the world, and on any device. We’re on a mission to connect a billion people with optimism and civility, and looking for amazing talent to help us get there. A career at Roblox means you’ll be working to shape the future of human interaction, solving unique technical challenges at scale, and helping to create safer, more civil shared experiences for everyone. Developer Monetization is the economic engine of Roblox and owns the systems responsible for over 70% of platform revenue. We build the in-engine and Studio infrastructure that lets millions of creators monetize their work and that powers how hundreds of millions of users discover and purchase virtual goods across the world's largest virtual economy. We're building the next generation of that economy, including systems that understand how players interact with the world in real time, boosting our capability to optimize the economy to better support our community.

You Will: - Build and evolve the in-engine C++ APIs at the core of Roblox's virtual economy, serving 20M+ QPS, gracefully degrading under pressure, and keeping the experience seamless for hundreds of millions of players. - Design systems that capture how players discover and interact with virtual goods inside an experience, turning spatial and behavioral signals into structured data that powers intelligent merchandising and economy optimization. - Push the boundaries of mobile performance. Profiling, optimizing, and finding creative ways to deliver rich monetization experiences within tight memory and frame budgets. - Lead projects from scoping through experimentation to launch, making key technical decisions, running A/B tests, and iterating based on what you learn. - Partner with product, design, data science, and ML engineers to shape the future of in-experience commerce on Roblox. You Have: - 3+ years of experience building production systems with a strong foundation in C++. - Experience shipping client-side or mobile software (iOS, Android, or game engines). - Strong intuition for user experience.

About Us At Cloudflare, we are on a mission to help build a better Internet. Today the company runs one of the world’s largest networks that powers millions of websites and other Internet properties for customers ranging from individual bloggers to SMBs to Fortune 500 companies. Cloudflare protects and accelerates any Internet application online without adding hardware, installing software, or changing a line of code. Internet properties powered by Cloudflare all have web traffic routed through its intelligent global network, which gets smarter with every request. As a result, they see significant improvement in performance and a decrease in spam and other attacks. Cloudflare was named to Entrepreneur Magazine’s Top Company Cultures list and ranked among the World’s Most Innovative Companies by Fast Company. At Cloudflare, we’re not looking for people who wait for a polished roadmap; we’re looking for the builders who see the cracks in the Internet that everyone else has simply learned to live with. We value candidates who have the instinct to spot a "normalized" problem and the AI-native curiosity to create a solution using the latest tools. Our culture is built on iteration, leveraging AI to ship faster today to make it better tomorrow, while ensuring that every improvement, no matter how small, is shared across the team to lift everyone up. If you’re the type of person who values curiosity over bureaucracy, and that AI is a partner in solving tough problems to keep the Internet moving forward, you’ll fit right in. Location- Austin, TX What you'll do We’re looking for a Software Engineer to join our Zero Trust team. You will be working on the Zero Trust desktop client , which protects corporate devices by securely and privately sending traffic from those devices to Cloudflare’s global network, which can apply advanced web filtering and advanced Zero Trust policies. In your role, you will predominantly be using Rust alongside platform-native languages & APIs to implement high-performance networking code that runs on multiple desktop platforms. You’ll be expected to improve the code quality and to build solid, testable, and well-documented foundations. You will be most successful in this role if you have a good understanding of operating system concepts (virtual memory, multi-threading, process lifecycle, etc.) and networking concepts & protocols (VPNs, firewalls, TCP/IP, UDP, DNS, QUIC, H/3, proxying, etc.). You will also have to interact with other languages, such as Dart, Typescript, and Python. As a Senior Software Engineer, you will be expected to lead the design and implementation of major development projects, working closely with our product managers and other teams to deliver customer-impacting features. You will mentor other engineers, raise the bar on testability and documentation, and represent the team in cross-org technical discussions. You will use AI-powered tools and systems as part of your daily workflow to analyze and extend our codebase, introspect production behavior, and accelerate problem-solving. You will work on stimulating problems born out of the scale of our deployment, and the stringent quality, performance, and security requirements of our product. Examples of desirable skills, knowledge, and experience - Demonstrated history of shipping and supporting client software on real end-user devices — including installer and auto-update flows, crash and telemetry reporting, and debugging issues against the long tail of real-world OS and hardware configurations - Excellent programming skills, with experience writing very high-quality and low-complexity code with thorough documentation. - Strong experience writing easily-testable and thoroughly-tested code (e.g. using dependency injection with the right abstractions) - Great experience using lower-level languages , such as Rust, C, C++ - Very comfortable writing multithreaded, asynchronous code - Strong experience with debugging network-related problems

About Anthropic Anthropic’s mission is to create reliable, interpretable, and steerable AI systems. We want AI to be safe and beneficial for our users and for society as a whole. Our team is a quickly growing group of committed researchers, engineers, policy experts, and business leaders working together to build beneficial AI systems. About the role: You want to build and run elegant and thorough machine learning experiments to help us understand and steer the behavior of powerful AI systems. You care about making AI helpful, honest, and harmless, and are interested in the ways that this could be challenging in the context of human-level capabilities. You could describe yourself as both a scientist and an engineer. As a Research Engineer on Alignment Science, you'll contribute to exploratory experimental research on AI safety, with a focus on risks from powerful future systems (like those we would designate as ASL-3 or ASL-4 under our Responsible Scaling Policy ), often in collaboration with other teams including Interpretability, Fine-Tuning, and the Frontier Red Team. Our blog provides an overview of topics that the Alignment Science team is either currently exploring or has previously explored. For the London team, we are opportunistically hiring for the following research areas: - AI Control: Creating methods to ensure advanced AI systems remain safe and harmless in unfamiliar or adversarial scenarios. - Alignment Stress-testing : Creating model organisms of misalignment to improve our empirical understanding of how alignment failures might arise. Note: Currently, the team's hub is in San Francisco, so we require all candidates to be based at least 25% in London and travel to San Francisco occasionally. Additionally, we are prioritizing growing our San Francisco teams, so you may not hear back on your application to the London team unless we see an unusually strong fit. For this role, we conduct all interviews in Python. Representative Projects: - Testing the robustness of our safety techniques by training language models to subvert our safety techniques, and seeing how effective they are at subverting our interventions. - Run multi-agent reinforcement learning experiments to test out techniques like AI Debate . &lt
