Cybersecurity Engineer - Red Team Operation

Important things for you

• Flexible working hours in the hybrid model (4/1) - working hours start between 7:00 a.m. and 9:00 a.m. We also have 30 days of occasional remote work.
• Annual bonus based on your annual performance and company results.
• Our team is based in Warsaw and Poznań.

About the job

• Massive Scale & Security Challenges: Secure, test and optimize a world-class, cloud and on-prem environment handling thousands of requests per minute. This is high-availability, high-performance security engineering in practice.
• Modern Tech Stack: Work within an advanced ecosystem where core technologies include specialized offensive and defensive security tools, automated SAST/DAST pipelines, C2 frameworks and cutting-edge cryptography. We are also pioneering the security of production-used AI models.
• True Ownership & Autonomy: We live by a "you build it, you run it" philosophy. You'll join an autonomous team with full ownership of your security services - from threat modeling and attack simulation to deploying protective guardrails.
• Complex Architectural Puzzles: From securing distributed systems to tackling novel AI vulnerabilities, you'll solve complex engineering problems that directly protect a massive, real-time marketplace.

Red Team Operations (RedSec) Focus on realistic, hands-on attack simulations rather than theoretical assessments. This is a highly autonomous role where you will actively validate defensive capabilities by independently designing "

Assume Breach" scenarios, developing custom offensive tooling to bypass modern EDR/XDR, operating dedicated Red Team infrastructure aligned with the MITRE ATT& CK framework and introducing AI-assisted techniques to maximize reconnaissance efficiency.

What's in it for you:

• Well-located offices (with e.g. fully equipped kitchens, bicycle parking, terraces full of greenery) and excellent work tools (e.g., raised desks, ergonomic chairs, interactive conference rooms).
• A 16" or 14" MacBook Pro or corresponding Dell with Windows (if you don't like Macs) and all the necessary accessories.
• A wide selection of fringe benefits in a cafeteria plan - you choose what you like (e.g., medical, sports or lunch packages, insurance, purchase vouchers).
• English classes that we pay for related to the specific nature of your job.
• A training budget, inter-team tourism (see more here), hackathons, and an internal learning platform where you will find multiple trainings.
• An additional day off for volunteering, which you can use alone, with a team, or with a larger group of people connected by a common goal.
• Social events for Allegro people - Spin Kilometers, Family Day, Fat Thursday, Advent of Code, and many other occasions we enjoy.

#goodtobehere means that:

• You will join a team you can count on - we work with top-class specialists who have knowledge- and experience-sharing in their DNA.
• You will love our level of autonomy in team organization, the space for continuous development, and the opportunity to try new things. You get to choose which technology solves the problem and you are responsible for what you create.
• You will be equipped with modern AI tools to automate repetitive tasks, allowing you to focus on analyzing complex threats, developing advanced security automation, and refining secure architectures.
• You will meet the Allegro Scale, which starts with over 1000 microservices, an open-source data bus (Hermes) with 300K+ rps, a Service Mesh with 1M+ rps, tens of petabytes of data, and production-used machine learning.
• You will become part of Allegro Tech - We speak at industry conferences, cooperate with tech communities, run our own blog (it's been over 10 years!), record podcasts, lead guilds, and we organize our own internal conference - the Allegro Tech Meeting. We create solutions we love (and can) to talk about!
