Staff/Lead Enterprise Security Engineer

we are looking for

This role is built for a security manager or lead who has done this at a bigger company and wants to build it again from scratch, on their own terms: automation-first and AI-forward, at a company moving fast enough to keep it interesting. You trade a big team and inherited playbooks for a blank page and real ownership. We are also open to an exceptional senior IC ready to own a broad program end to end.

In both cases:

- Highly independent. You set priorities against a broad surface and a fast M&A cadence without being told what matters.

- Confident and credible with people outside your team. You can represent security to portfolio founders and engineering leads and bring them along.

- Deep, hands-on security engineering across endpoint, detection and response, identity, cloud, SaaS, and email, and the ability to build tooling and automation from scratch.

- A high bar for the craft: threat modeling, secure design, detection quality, and IR rigor.

- Comfortable in greenfield and ambiguity. You would rather define a program than inherit one.

- Humility : We acknowledge that the path to getting to the right answer involves being wrong along the way. We have strong beliefs which are weakly held. We actively seek new ideas and believe we can learn from anyone at any time.

- Honesty : We are truth seeking in our approach to business problems. Business is a repeat game and we believe that human relationships generate alpha. We understand that trust is earned over a lifetime and can be lost in an instant.

- Hunger : We play to win. We hold ourselves to high standards and will not be outworked. We take pride in having a deep sense of responsibility to ourselves, each other, our partners, and our customers.

We believe to whom much is given much is expected.

- Horizon : We seek to build a generational software company. This will take decades. We manage our expectations and those of our partners to take advantage of the 8th wonder of the world - compounding growth.

How We Use AI in Our Hiring Process: To ensure transparency, we want candidates to know that Beacon Software uses Artificial Intelligence and AI-enabled tools to assist with screening, reviewing, organizing and highlighting profiles and applications that match the key requirements for each role.

AI does not make hiring decisions: Every application is reviewed by a member of our team, and all decisions throughout the process are made by humans. We use AI to support efficiency and consistency, not to replace human judgment. We are committed to a fair, thoughtful, and equitable experience for every candidate.
