Вакансии

Location: Riyadh, Saudi Arabia; Doha, Qatar We’re on the hunt for a Cybersecurity Incident Response Specialist with the curiosity of a detective, the calm of a bomb disposal expert, and the analytical instincts of someone who enjoys untangling the world’s messiest PowerShell scripts. You’ll be joining the NetWitness Incident Response team in Saudi Arabia, working alongside a group of battle-tested DFIR professionals who thrive on turning chaos into clarity. You’ll investigate security incidents, perform digital forensics, analyze malware, and help organizations recover from the kind of problems that usually start with, "We just saw some unusual network traffic..." If you enjoy pulling threads to find out what really happened, and you’ve ever taken apart malware “just to see what makes it tick,” you’ll fit right in. Key Responsibilities Conduct cyber incident investigations and digital forensic analysis (sans drama, but with precision). Perform malware triage, memory forensics, and compromise assessments. Document findings clearly enough that even your non-technical colleagues will think you’re a wizard. Work with global NetWitness IR experts to respond to complex attacks and improve detection. Share knowledge, challenge hypotheses, and occasionally utter phrases like “It depends” with confidence. Requirements At least 5 years of solid, hands-on experience in cybersecurity. Minimum 2 years of direct involvement in incident response, digital forensics, or malware analysis. Alternatively, visible public research or open-source projects in DFIR or malware analysis are perfectly acceptable — we value results over titles. Strong technical foundation in Windows, Linux, and network investigations. Comfortable using tools like NetWitness, Volatility, Velociraptor, or your own custom scripts. Scripting skills in Python, PowerShell, or Bash – bonus points if you’ve written something that made your teammates both grateful and slightly afraid. SANS certifications (GCFA, GREM, GNFA, GCFE, etc.) are definite pluses, as is a calm demeanor during incidents that make others panic. Fluency in English; Arabic proficiency is a welcome advantage. Benefits Work with some of the brightest minds in digital forensics and incident response. Get hands-on with major cybersecurity incidents while using serious tooling (and a healthy dose of wit). Be part of a team that values curiosity, professional rigor, and the occasional well-timed sarcastic observation. Continual learning and growth opportunities through global collaboration and SANS-aligned training. If this sounds like your sort of challenge — and you’ve been known to say “I’ll just have a quick look at that memory dump” moments before losing three hours — we’d quite like to hear from you.

Location: San Francisco, CA 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: When you see what modern language models are capable of, do you wonder, "How do these things work? How can we trust them?" The Interpretability team at Anthropic is working to reverse-engineer how trained models work because we believe that a mechanistic understanding is the most robust way to make advanced systems safe. Think of us as doing "neuroscience" of neural networks using "microscopes" we build - or reverse-engineering neural networks like binary programs. More resources to learn about our work: Our research blog - covering advances including Monosemantic Features and Circuits An Introduction to Interpretability from our research lead, Chris Olah The Urgency of Interpretability from CEO Dario Amodei Engineering Challenges Scaling Interpretability - directly relevant to this role 60 Minutes segment - Around 8:07, see a demo of tooling our team built New Yorker article - what it's like to work on one of AI's hardest open problems Even if you haven’t worked on interpretability before, the infrastructure expertise is similar to what's needed across the lifecycle of a production language model: Pretraining: Training dictionary learning models looks a lot like model pretraining - creating stable, performant training jobs for massively parameterized models across thousands of chips Inference: Interp runs a customized inference stack. Day-to-day analysis requires services that allow editing a model's internal activations mid-forward-pass - for example, adding a "steering vector" Performance: Like all LLM work, we push up against the limits of hardware and software. Rather than squeezing the last 0.1%, we are focused on finding bottlenecks, fixing them and moving ahead given rapidly evolving research and safety mission The science keeps scaling - and it's now applied directly in safety audits on frontier models, with real deadlines. As our research has matured, engineering and infrastructure have become a bottleneck. Your work will have a direct impact on one of the most important open problems in AI. Responsibilities: Build and maintain the specialized inference and training infrastructure that powers interpretability research - including instrumented forward/backward passes, activation extraction, and steering vector application Resolve scaling and efficiency bottlenecks through profiling, optimization, and close collaboration with peer infrastructure teams Design tools, abstractions, and platforms that enable researchers to rapidly experiment without hitting engineering barriers Help bring interpretability research into production safety audits - with real deadlines and high reliability expectations Work across the stack - from model internals and accelerator-level optimization to user-facing research tooling You may be a good fit if you: Have 5-10+ years of experience building software Are highly proficient in at least one programming language (e.g., Python, Rust, Go, Java) and productive with Python Are extremely curious about unfamiliar domains; can quickly learn and put that knowledge to work, e.g. diving into new layers of the stack to find bottlenecks Have a strong ability to prioritize the most impactful work and are comfortable operating with ambiguity and questioning assumptions Prefer fast-moving collaborative projects to extensive solo efforts Are curious about interpretability research and its role in AI safety (though no research experience is required!) Care about the societal impacts and ethics of your work Are comfortable working closely with researchers, translating research needs into engineering solutions. Strong candidates may also have experience with: Optimizing the performance of large-scale distributed systems Language modeling fundamentals with transformers High Performance LLM optimization: memory management, compute efficiency, parallelism strategies, inference throughput optimization Working hands-on in a mainstream ML stack - PyTorch/CUDA on GPUs or JAX/XLA on TPUs Collaborating closely with researchers and building tooling to support research teams; or directly performed research with complex engineering challenges Representative Projects: Building Garcon , a tool that allows researchers to easily instrument LLMs to extract internal activations Designing and optimizing a pipeline to efficiently collect petabytes of transformer activations and shuffle them Profiling and optimizing ML training jobs, including multi-GPU parallelism and memory optimization Building a steered inference system that applies targeted interventions to model internals at scale (conceptually similar to Golden Gate Claude but for safety research) Role Specific Location Policy: This role is based in the San Francisco office; however, we are open to considering exceptional candidates for remote work on a case-by-case basis. The annual compensation range for this role is listed below. For sales roles, the range provided is the role’s On Target Earnings ("OTE") range, meaning that the range includes both the sales commissions/sales bonuses target and annual base salary for the role. Annual Salary: $315,000 — $560,000 USD Logistics Minimum education: Bachelor’s degree or an equivalent combination of education, training, and/or experience Required field of study: A field relevant to the role as demonstrated through coursework, training, or professional experience Minimum years of experience: Years of experience required will correlate with the internal job level requirements for the position Location-based hybrid policy: Currently, we expect all staff to be in one of our offices at least 25% of the time. However, some roles may require more time in our offices. Visa sponsorship: We do sponsor visas! However, we aren't able to successfully sponsor visas for every role and every candidate. But if we make you an offer, we will make every reasonable effort to get you a visa, and we retain an immigration lawyer to help with this.
