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.\nAt 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.\nWe’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.\nIf you want comfort and routine, this isn’t it. If you want to operate like an actual attacker - welcome.\nKey Responsibilities:\nPlan and execute advanced red team operations, including adversary emulation and scenario-based testing.\nDevelop and maintain custom tooling for offensive security operations.\nPerform vulnerability assessments, exploit development, and post-exploitation activities across diverse environments.\nConduct reconnaissance, initial access, lateral movement, and persistence techniques using C2 frameworks.\nAnalyze and reverse engineer applications, binaries, and protocols.\nCollaborate with blue teams to improve detection and response capabilities.\nResearch and publish technical blog articles, CVEs, and open-source tools.\nParticipate in CTFs, bug bounty programs, and contribute to the security community.\nShare knowledge across teams and mentor junior engineers.\nRequired Skills & Experience:\nPenetration testing and red teaming experience.\nSolid background in system administration and software development.\nDeep understanding of vulnerabilities and exploitation techniques.\nProficiency in at least one programming language (e.g., Python, C/C++, Go).\nExperience with:\nBurpSuite, Nmap, Nessus, and other scanning tools\nCloud environments (AWS, Azure, GCP)\nActive Directory and EntraID\nFamiliarity with networking fundamentals and operating systems (Windows, Linux)\nStrong communication and documentation skills. \nPreferred Qualifications (Nice-to-Have):\nExperience in incident response and threat hunting.\nCertifications such as OSCP, CRTO, CRTL, OSEP, OSWE, OSED, CPTS, CAPE, CWES, CISSP.\nContributions to CVEs or security research.\nWhat We Offer:\nWork in a dynamic, international environment. \nOpportunities for professional growth and involvement in strategic projects. \nCompetitive salary and benefits package. \nHybrid working model.\n\nHere at Atos, diversity and inclusion are embedded in our DNA. Read more about our commitment to a fair work environment for all.\nAtos is a recognized leader in its industry across Environment, Social and Governance (ESG) criteria.
