Senior Staff Security Engineer

Description

Join us in building the future of finance.

Our mission is to democratize finance for all. An estimated $124 trillion of assets will be inherited by younger generations in the next two decades. The largest transfer of wealth in human history. If you’re ready to be at the epicenter of this historic cultural and financial shift, keep reading.

At the company, we believe in the power of in-person work to accelerate progress, spark innovation, and strengthen community. Our office experience is intentional, energizing, and designed to fully support high-performing teams.

We are building an elite team, applying frontier technologies to the world's biggest financial problems. We're looking for bold thinkers. Sharp problem-solvers. Builders who are wired to make an impact. The company isn't a place for complacency, it's where ambitious people do the best work of their careers. We're a high-performing, fast-moving team with ethics at the center of everything we do. Expectations are high, and so are the rewards.

The company's Security Operations team operates across two distinct disciplines: proactive security — finding threats and vulnerabilities before attackers do — and reactive security — detecting, investigating, and evicting threat actors in real time. Together, these functions form a complete picture of what it takes to protect one of the most active financial platforms in the world. The team operates in an environment of genuine complexity: high-volume security events, sophisticated threat actors, and a constant arms race against adversaries who are increasingly leveraging AI to move faster and go deeper.

The threat landscape is changing. AI-powered attackers don't move like traditional adversaries — they are faster, more adaptive, and harder to track with static defenses. The company's approach to this isn't passive. We are building dynamic, intelligent defensive systems designed to detect, deceive, and outmaneuver agentic attackers — and we need a Senior Staff Security Engineer to help us build them.

As a Senior Staff Security Engineer, Security Operations , you will operate at the intersection of operational security tradecraft and cutting-edge AI-driven defense. You will bring deep expertise across both the offensive and defensive sides of security operations and you will push the boundaries of what's possible when those disciplines are combined with modern AI tooling. This is a 0→1 technical leadership role for someone who doesn't just follow the security playbook, but looks to rewrite it.

This role is based in our Menlo Park, New York City, or Bellevue office, with in-person attendance expected at least 3 days per week.

At the company, we believe in the power of in-person work to accelerate progress, spark innovation, and strengthen community. Our office experience is intentional, energizing, and designed to fully support high-performing teams.

Responsibilities

• Serve as the Security Operations AI Tech Lead for the company's offensive and defensive security functions — Owning the technical creation and execution of the company’s Security OperationsAI roadmap for defensive and offensive operations
• Lead offensive security research— applying deep red team, penetration testing, and application security expertise to proactively identify and close critical attack surfaces before adversaries find them
• Architect and build next-generation defensive capabilities that go beyond static detection — designing intelligent systems that actively engage, deceive, and track sophisticated threat actors including AI-powered attackers
• Drive the company's AI-forward security strategy — not just using AI as a productivity tool, but as a core architectural component of how we build a synthetic workforce to scale against agentic and automated adversaries
• Identify emerging threat actor motivations and attack patterns especially in the AI space, translating intelligence into proactive defensive architectures that stay ahead of the threat curve
• Set technical standards and mentor security engineers within Security Operations, elevating the overall capability of the org
• What you bring
• 12+ years of security engineering experience with demonstrated depth across both offensive security (red team, penetration testing, application security, vulnerability management) and defensive security (incident response, detection engineering, threat intelligence)
• Demonstrate impact by innovating with AI in Security Operations — You’ve moved orgs well beyond the chatbot experience and implemented measurable success in uplifting Security Operations with AI.
• Proven track record of technical leadership at the Senior Staff, Principal, or Distinguished level — you've set org-wide or company-wide security direction, not just executed within a team
• Deep expertise in application security — you understand how modern software is built and where it breaks, and you can operate equally well as a security engineer and a software engineer
• Strong background in threat detection and security operations — you understand how attackers operate and how to build systems that catch them faster
• A genuine, informed point of view on AI in the security domain — you're not using AI to write scripts, you're thinking about how AI fundamentally changes both the attack surface and the defensive toolkit
• Proficiency with cloud infrastructure security (AWS preferred), telemetry and observability tooling, and the technical underpinnings of large-scale detection pipelines
• Exceptional technical communication skills — you can write, brief, and influence at the executive level as well as go deep with engineers on implementation details
• Security certifications (OSCP, GREM, GXPN, or equivalent) are a plus — but demonstrated capability will always outweigh paper credentials here
