- Integrate systems using APIs (Graph API, REST, etc) to enhance security workflows.
- Perform vulnerability assessments, review system configurations, and develop practical mitigation strategies.
- Contribute to incident response activities including investigation, containment, communication, and remediation.
- Work closely with engineering, technology, and business teams to embed security best practices.
Who you are

- At least 5 years experience in an information security or technical engineering role.
- Ability to apply analytical thinking to technical problems within a fast-moving environment.
- Comfortable with both Windows and Linux environments; familiarity with common security technologies (firewalls, endpoint protection, log management, vulnerability scanning, network security).
- Solid scripting skills in PowerShell and/or Python
- Knowledge of secure Identity Management, authentication principles, and modern access control patterns.
- Experience using security tooling such as EDR, SIEM, SOAR, CASB, etc
- Experience securing workloads running both on-premise (bare-metal / container) and on IaaS platforms.
- Familiarity with identity lifecycle processes, RBAC, PAM, and privileged identity controls.
- Understanding of vulnerability management tools (Nessus/Tenable, RunZero, etc) and secure configuration standards.
- Experience with data protection, DLP, or information protection solutions (e.g., Microsoft Purview, DLP rules, classification/labelling).
Please note that we welcome interest from candidates with varying levels of experience; many successful candidates do not meet every single requirement. If you're excited about this role, please apply and allow our recruiters to assess your application.
What you’ll get
You’ll join a culture of collaboration and excellence, where you’ll be surrounded by curious thinkers and creative problem solvers. Driven by a passion for continuous improvement, you’ll thrive in a supportive, high-performing environment alongside talented colleagues, working collectively to tackle some of the most complex problems in the financial markets.
In return for your expertise, you will have access to a range of Optiver perks, including:
- A performance-based bonus structure unmatched anywhere in the industry.
- The chance to work alongside diverse and intelligent peers in a rewarding environment.
