Are you ready to be the first line of offense for one of the fastest-growing companies in the Cryptocurrency and Blockchain space? We're looking for a Security Engineering Intern (Red Team Sector) to think like an adversary, break things before attackers do, and help us build a platform our users can trust with their assets.
In crypto, every vulnerability has an immediate, irreversible dollar value attached. That's the bar you'll be operating at.

What you'll be doing:

- Offensive security engagements across our web, mobile, API, and microservice surfaces, as well as cloud infrastructure and internal systems.

- Conduct manual secure code review on production codebases to find vulnerabilities that scanners miss, with particular attention to financial logic, race conditions, and trust-boundary violations.

- Research emerging threats in Web3, mobile, and cloud — new exploitation techniques, smart contract attack patterns, DeFi exploits, supply chain attacks — and translate them into proactive testing methodologies before they hit production.

- Write robust scripts, automate offensive workflows, and create frameworks that scale red team coverage across a fast-moving codebase.

What we're looking for:

- Knowledges in offensive security, penetration testing, or red teaming, with demonstrated hands-on experience in web and mobile application security, through CTF competition or bug bounty engagement.

- Final year at university with degree focusing on Computer Science, Information Systems, Engineering.

- Strong fundamentals in offensive security, application security, and security engineering.

- Strong familiarity with Linux and cloud ecosy...
