About the project
This is NOT another consultancy hamster wheel where you spend your week glued to Burp Suite and Word running the same tired web/API/fat client playbook on Monday and shipping the same predictable report on Friday.
Here, you operate.
You’ll emulate real world threat actors and run full scale attack campaigns across complex environments. No two projects are the same: one week you’re building and operating red team infrastructure, the next you’re tearing through external attack surface, pivoting deep inside networks, or pressure-testing detection and response in real time.
At the same time, this isn’t just adversary simulation. You’ll also conduct penetration tests across a wide variety of targets, using them as a foundation, not the ceiling, for deeper, more creative offensive work.
We’re looking for builders and operators, people who don’t only follow checklists, but think in chains, and have an offensive mindset. People who automate the boring parts so they can focus on the interesting ones.
If you want comfort and routine, this isn’t it. If you want to operate like an actual attacker - welcome.
