Why work at Cossack Labs? #

Some companies prioritise talent and value proposition, while others understand business and would take any job that pays well. However, only few companies choose to specialise in difficult tasks as their primary competency.

We take on difficult jobs, we take mission-critical software and make it mission-secure.

• Virtualise OT infrastructure securely in the presence of active adversaries, preventing them from accessing the susceptible nation-wide network? ✓ Check.
• Provide immediate application security and infrastructure security guidance for mission-critical application that will be deployed on thousands of devices on the front-line tomorrow? ✓ Check.
• Validate counter-reverse engineering protections for power grid hardware to ensure that previously air-gapped environments were safe to open up to the outside world? ✓ Check.
• Ensure that software platforms for exchange of sensitive documents actually have a top-tier SSDLC programme that supplements missing capabilities and builds out processes? ✓ Check.

We operate as a lean core team and a diverse network of experts. The finest people you may work with include PhDs in information security and cryptography, infosec community standard contributors, in-depth experts in rare security topics, and business-centric security engineers with broad experiences. Some of your teammates have worked in infosec since the 1990s and saw the industry grow from nothing. Some of them helped write standards that govern security around you. Maybe someone’s work actually keeps the lights up while you’re reading this?

Our core engineers go through extensive indoctrination and training to become disciplined, stringent, self-sufficient field unit who owns the outcomes rather than just showing up for work.

As you grow into the Cossack Labs engineer, you’ll work on slow-paced projects to learn and improve, internal projects to innovate and build tools, and of course a few fires, because no smooth sea can make a skilled sailor. You’ll discover what works for you and what you need to learn.

We help innovators who are launching new venues of civilisation while facing significant security risks in becoming more secure and resilient. Customers trust us to achieve their business goals, not merely address gaps someone else has to identify first.
