Job description
Chicago preferred | NYC / London | Remote considered
Compensation open - scope to exceed your current package
I’m working on a talent-led search for a Senior Offensive Security Engineer to join a highly technical global financial organisation building out its offensive security capability.
This isn’t a role where you’ll simply be running automated pentesting tools.
They want someone who genuinely thinks like an attacker.
You’ll essentially operate as an internal hacker. Continuously looking for ways into systems, identifying weaknesses and then working directly with infrastructure, development and security teams to remediate and retest them.
You’ll have a lot of ownership from day one, including:
Red teaming and adversary simulation
Penetration testing across infrastructure, applications, APIs and cloud
Exploiting vulnerabilities across Windows, Linux and macOS environments
Building your own offensive tooling alongside using established tools
Working closely with defensive teams on purple team exercises
Owning vulnerability remediation through to resolution
Testing emerging attack vectors including AI and LLM environments
Helping shape the wider offensive security methodology and roadmap
I’m looking for someone with 5+ years of hands-on offensive security experience who can take an engagement from reconnaissance through exploitation, privilege escalation and lateral movement.
Strong communication is equally important. You need to be able to document what you find, explain the risk and work collaboratively with engineering teams to actually fix it.
Consultancies, financial institutions and mature internal red teams are all relevant backgrounds.
There is currently no dedicated person doing this internally, so there is significant scope to make the function your own. As the capability grows, this could also develop into a Lead position.
Compensation is deliberately open. The priority is finding the right person and I have flexibility to discuss packages that exceed current compensation for exceptional profiles.
