Platform Security Engineer

5+ years of hands-on experience in platform security and cyber defense

Have an exceptional eye for finding flaws others miss, and instinctively ask "how would I break this"

Lead with a strong grasp of offensive security, anticipating risk from an adversary's perspective rather than checking compliance boxes

Bring a builder's mindset — you have experience shipping secure software to production

Have strong judgment to identify the most important security vulnerabilities and put into practice

Reduce risk through secure design and simplicity; advocate for fundamentals like least privilege, defense-in-depth, and minimizing complexity

Are energized by ambiguity and high autonomy

Hands-on experience securing complex cloud and multi-tenant environments, especially ones deployed inside customer VPCs

Familiarity with AI/agent-specific risks: prompt injection, tool use abuse, data and model exfiltration

Background in offensive security, vulnerability research, or red teaming against cloud or AI systems

Experience using LLMs to accelerate security workflows — detection, investigation, triage, or automated response

Track record taking compliance programs (SOC 2, ISO 27001, HIPAA, FedRAMP) to completion as engineering efforts

Previous experience as a founder, security lead, or early engineer at a zero-to-one company

Applied Compute builds Specific Intelligence for the enterprise. We provide the continual learning infrastructure for companies to build agent workforces trained on proprietary data and institutional expertise. Our researchers and platform embed directly within customer environments to build custom evals, train models, and deploy agents that get better with use.

Why we’re excited: We get to work at a rare intersection. Our product team builds the platform powering a new generation of digital coworkers. Our research team pushes the frontier of post-training and reinforcement learning. Our applied AI team sits side-by-side with customers as they ship agents into production. This combination of strong product, deep research, and boots on the ground is what we believe it takes to bring AI to the enterprise. We are product-led, research-enabled, and forward-deployed.

Who we are : We’re a team of engineers, researchers, and operators. Many of us are former founders. We've built RL infrastructure at OpenAI, data foundations at Scale AI, and systems at Together, Two Sigma, Watershed, and others. We work with F50 customers and are fortunate to be backed by partners like Kleiner Perkins, Benchmark, Sequoia, Lux, and Greenoaks.

Who Thrives Here : We're looking for people who are excited about applying novel research and complex systems to real-world problems. Our team genuinely enjoys working with customers: listening, empathizing, and understanding how work actually gets done in their organizations. Former founders, people who've built a lot of side projects, or anyone who's shown they can own something end-to-end, tend to do well here.
