Tech | Security | Pentester at Picnic

In a nutshell

At Picnic, we're building the most secure milkman on earth, and we need someone to help us verify that reality. As our Pentester in the SecOps team, you’ll combine offensive and defensive security skills to identify vulnerabilities, strengthen defenses, and improve our security culture. You’ll conduct pentests across web, mobile, network, and cloud systems, run red teaming exercises, and manage our vulnerability programs. You’ll also empower development teams to adopt secure coding practices while enhancing our pentesting workflows with MCPs and LLMs.

Tricks of the trade

  • Ownership: Take charge of the pentesting process, from planning to execution and reporting, ensuring comprehensive coverage across all Picnic services while encouraging continuous improvement
  • Management: Own the Vulnerability Disclosure Program, manage remediation workflows, and define KPIs to track coverage and effectiveness
  • Collaboration: Work closely with development teams to integrate security best practices into the software development lifecycle
  • Innovation: Leverage MCPs and LLMs to enhance pentesting efficiency and automation and build customized and scalable solutions for Picnic.
  • Training: Conduct application security workshops to raise awareness and promote secure coding practices among developers
  • Our tech: AWS, Google Workspace, Keycloak, Docker, Kubernetes (EKS), Helm, Terraform, Python, SAML, OAuth, OpenID, JWT (JSON Web Tokens), 802.1x, Atlassian (Jira, Confluence), IoT, Web & Mobile Apps, APIs.

We’re looking for

  • Bachelor’s or Master’s degree in Computer Science, Cybersecurity, Information Security, or a related field (or equivalent practical experience).
  • At least 4 years of relevant experience in pentesting web, mobile, network and cloud environments.
  • Strong communication skills to report findings clearly and train development teams
  • Curious and pragmatic, keep things simple without losing quality, and bring structure and organisation to the unknowns.
  • A certificate of conduct (Verklaring Omtrent het Gedrag, VOG) would be requested during the process.
