Job description

Our Mission

Rebuild how the world works, to make institutions work better for the people they serve.

About Brain Co.

Brain Co. builds AI-native operating systems for large, regulated institutions. Each system is built for a specific industry, powered by agents that push real workflows forward. Underneath it all is Atlas, our proprietary platform that keeps customers in control, secure by design, and never locked into one model.

Why Now

Brain Co. is entering its next phase of production deployments on a national scale with an elite team built from Palantir, Google, Meta, and Nvidia, and a growing footprint across government, insurance, health, and financial services.

Joining now means shaping both the company and a new category of applied AI. Every project here ships to production and is expected to create measurable customer value and impact.

You’ll work alongside exceptional peers on some of the hardest problems in applied AI. It’s the kind of work you’ll still be proud of in ten years from now.

About The Role

We’re hiring a Security Engineering Leader to help make security engineering more effective, scalable, and repeatable as Brain Co. grows. You’ll report to the Head of Security and serve as a close partner in leading the function.

Brain Co. works with sensitive customer data in a high‑stakes environment with very low tolerance for risk. This is a player‑coach role: you’ll set direction, develop leaders, improve how the team operates, and stay close enough to the technical work to guide difficult decisions.

The initial scope is intentionally focused and expected to grow through results. The right person is comfortable building in a greenfield environment, creating high ownership, and translating security risk into clear priorities for technical and non‑technical partners. The mandate from day one is to develop people, improve execution, and make disciplined choices about the risks and systems that matter most.

What You’ll Lead & Build

• Set and refine the security engineering roadmap in partnership with company and engineering leadership.
• Automate and operationalize how security engineering engages with the rest of the company.
• Strengthen existing SLAs, KPIs, ownership models, and operating rhythms, then use them to improve velocity and security outcomes.
• Drive operational excellence across security engineering domains, including vulnerability management, application and infrastructure security, incident response, monitoring, and automation.
• Turn effective security engineering practices into a repeatable system that scales beyond individual heroics.
• Lead, coach, and grow a high‑performing team; develop managers and technical leaders through clear expectations, feedback, and mentorship.
• Translate strategy into team priorities, individual goals, and an accountable execution plan.
• Stay hands‑on in technical decisions, architecture review, code review, and implementation when the work requires it.
• Partner across engineering and product to embed security into the software development lifecycle and make the secure path the practical path.

What We’re Looking For

• Experience managing managers and developing leaders at multiple levels.
• Hands‑on security engineering leadership and the ability to build a function in a zero‑to‑one environment.
• Broad knowledge across multiple security domains—such as vulnerability management, incident response, security monitoring, application security, or cloud security—with deep expertise in at least one.
• A player‑coach track record: able to guide technical design and execution while managing people, priorities, and processes.
• Strong prioritization judgment when the scope is broad and the tolerance for risk is low.
• Experience improving how a team operates, including how work is measured, assigned, and delivered.
• Experience automating a security team’s engagement model or improving its SLA and KPI practices.
• Experience turning strategy into roadmaps, measurable outcomes, and cross‑functional execution.
• Strong communication with technical and non‑technical stakeholders, including the ability to articulate business risk and secure alignment.
• A track record of hiring, coaching, mentoring, and raising the performance of technical teams and leaders.

Experience in a SaaS or AI company with low risk thresholds, or building security infrastructure, monitoring, and automation, is helpful but not required. clients who may be skeptical of or unfamiliar with the tooling.

Benefits

• Competitive salary
• Medical, Dental, and Vision (100% Coverage)
• Paid Maternity and Paternity Leave
• 401(k)
• Daily Lunches + Dinners
• Commuter Benefits
