About Coalfire

Coalfire is on a mission to make the world a safer place by solving our clients’ hardest cybersecurity challenges. We work at the cutting edge of technology to advise, assess, automate, and ultimately help companies navigate the ever-changing cybersecurity landscape. We are headquartered in Chicago, Illinois with offices across the U.S. and U.K., and we support clients around the world.

But that’s not who we are – that’s just what we do.

We are thought leaders, consultants, and cybersecurity experts, but above all else, we are a team of passionate problem-solvers who are hungry to learn, grow, and make a difference.

The Consultant works closely with Project Managers, Delivery Directors, and other Delivery team members to lead engagements, assessing the security of various types of client applications and supporting infrastructure against security best practices. The Consultant is a technical leader with broad technical skills, meeting the objectives of their engagements, collaborating with clients, mentoring teammates, and providing subject matter expertise across one or more technical domains. The Consultant is a trusted advisor to clients, and through objective testing and results reporting, supports the client in making well-informed, risk-based decisions to improve overall security posture.
