About you and the role

You may be an experienced Security Engineer looking for your next challenge, or someone ready to step into a role with greater scope and impact. You do not settle for “good enough.” You dig into code, systems, and processes to uncover deeper risks and design resilient solutions. You thrive on collaboration, embedding security into the engineering lifecycle and helping teams build secure by default. You stay curious and adaptable, embracing new tools and modern security practices while shaping solutions that scale. Your drive for excellence and passion for security raise the bar for your own work and inspire confidence in the people around you.

At PartnerStack, security is not a checkbox. It is part of our culture and product DNA. We treat Security and Trust as competitive advantages that set us apart, making transparency, accountability, and continuous improvement core to how we operate. Our mission is to continually elevate our security posture and establish ourselves as an industry leader. We are looking for someone who shares this ambition.

What you’ll do

• Embed application and cloud security into our engineering lifecycle, partnering with developers at every stage
• Implement and manage automated scanning solutions (SAST, DAST, dependency, IaC) in CI/CD pipelines
• Lead triage and remediation of vulnerabilities, coordinating across engineering, product, and compliance
• Build and tune cloud security controls (IAM, monitoring, logging, container and network security)
• Provide developer-friendly security guidance and code review support
• Support compliance initiatives (SOC 2, ISO 27001, NIST CSF) with strong technical evidence
• Establish scalable detection and monitoring that ties into SIEM/SOC workflows

Our Tech Stack

• Google Cloud Platform
• Kubernetes
• PostgreSQL
• Redis
• Python
• Vue.js

You're a great candidate if...

• 3+ years of hands-on security engineering or application security experience
• Proven ability to design, implement, and maintain automated security testing
• Strong knowledge of OWASP Top 10, CWE Top 25, and CIS Controls
• Working experience with cloud-native environments (we use GCP)
• Familiarity with compliance frameworks and audits
• Ability to read and write high-quality application code
• A builder’s mindset: willing to be hands-on now, while shaping the foundation for a growing security team
