Staff Security Engineer, Product

Staff Security Engineer

Our mission is to transform high finance by making capital markets faster, smarter, and more accessible. At Rogo, we're making Wall Street AI-native, empowering finance professionals at the world's top investment banks, private equity funds, and investment firms with AI that delivers unparalleled speed, accuracy, and insight. We're not just improving financial workflows; we're redefining them from the ground up.

This is a unique opportunity to join a generational company at a key inflection point. With a rapidly growing, global client base, proven product-market fit, and backing from world-class investors, we are scaling quickly and defining a new category of enterprise AI.

Our team is sharp, motivated, and deeply committed to the mission. We operate with intensity, take ownership of complex problems, and stay relentlessly focused on our users. If you thrive in a fast-paced environment, demand excellence, and want to help build the future of finance, we invite you to join us.

What You Will Own

You will be Rogo's primary offensive security capability, finding, exploiting, and eliminating vulnerabilities across our products, APIs, and infrastructure before external attackers or penetration testers do.

• Conduct hands-on penetration testing and red team assessments against Rogo's applications, APIs, AI/ML pipelines, and cloud environments on a continuous basis, not just during annual engagements.
• Build agentic security tooling that finds, validates, and patches vulnerabilities end-to-end, minimizing manual intervention across code review, dependency management, and IaC.
• Develop and maintain custom offensive tooling, exploit chains, and attack simulations tailored to Rogo's AI platform and architecture.
• Build and operate automated security testing and remediation pipelines that scale offensive coverage without linearly scaling headcount.
• Perform deep adversarial testing of AI-specific attack surfaces: prompt injection, model manipulation, data poisoning vectors, agent-based workflows, and tenant isolation boundaries.
• Own vulnerability research and bug hunting across the product, go beyond scanner output to find the logic flaws, auth bypasses, and chained exploits that automated tools miss.
• Design and execute threat modeling sessions with engineering teams, translating offensive findings into concrete, prioritized remediation that ships in the same sprint.
• Build attack simulation environments and continuously validate security controls against real-world TTPs and customer-driven pen test scenarios.
• Contribute directly to backend codebases, fix critical vulnerabilities, harden authentication and authorization flows, and build security primitives into the platform.
• Lead purple team exercises: collaborate with infrastructure and engineering teams to test detection and response capabilities against your offensive scenarios.
• Own the relationship with external pen test firms and drive remediation of findings to closure.
• Share offensive tradecraft, emerging attack techniques, and lessons learned with engineering and leadership to continuously raise security awareness.

Great Candidates Often

• Have professional penetration testing experience across web apps, APIs, cloud environments, and ideally AI/ML systems. You've written real exploits, not just run scanners.
• Have built or are excited to build agentic security tooling that autonomously finds, validates, and patches vulnerabilities, minimizing human-in-the-loop remediation.
• Have professional development experience in a strongly typed language (e.g., Rust, Go, Java, C++) alongside scripting languages (Python, Bash) for exploit development and tooling.
• Are comfortable with Burp Suite, Nuclei, Semgrep, custom fuzzing frameworks, and building your own tools when off-the-shelf doesn't cut it.
• Have integrated automated security checks into CI/CD pipelines (SCA, SAST, DAST) and understand how to give developers fast, actionable feedback without blocking velocity.
• Are comfortable with infrastructure automation (Terraform, Kubernetes) and can identify misconfigurations and attack paths in AWS/GCP environments.
• Communicate crisply and can collaborate effectively with developers, product teams, and leadership.
• Have applied knowledge of threat modeling, cryptography fundamentals, and compliance frameworks (SOC 2, ISO 27001/42001, NIST CSF).

Bonus

• OSCP, OSWE, GXPN, GWAPT, CPTS, or similar offensive security certifications.
• Experience testing multi-tenant SaaS platforms serving regulated industries (financial services is a strong plus).
• Hands-on cloud penetration testing experience in AWS or GCP (privilege escalation, cross-account attacks, metadata abuse).
• Kubernetes security testing (RBAC abuse, container escapes, admission controller bypasses, network policy evasion).
• Bug bounty track record or published CVEs / security research.
• Experience in customer-facing security conversations, deep-dive technical sessions, pen test debrief calls, and security architecture reviews.

Who You Are

• You thrive in fast-paced environments. You are high-intensity and care a lot about what you do, and you're ecstatic to work at a startup.
• You are ambitious. You have fun solving problems that others think are impossible.
• You are curious. You find joy in learning about AI, technology, and finance.
• You are an owner. You are autonomous, self-directed, and comfortable working with ambiguity.
• You are collaborative, organized, thoughtful, and kind.

Why Join Rogo?

• Exceptional traction: strong PMF with the world's largest investment banks, hedge funds, and private equity firms.
• World-class team: we take talent density seriously. We like working with incredibly smart, driven people.
• Velocity: we work fast, which means you learn a lot and constantly take on more.
• Frontier technology: we're developing cutting-edge AI systems, pushing the boundaries of reinforcement learning and published research, redefining what's possible, and inventing the future.
• Cutting Edge Product: Our platform is state-of-the-art and crazily powerful. We're creating tools that make people smarter, reinventing finance works.
