Job Description

The Challenge

At Dialectica we're building something that thinks. Want to secure the future with us?

We are in the lookout for a security leader who gets excited about building secure systems from the ground up. Someone who sees security not as a roadblock, but as an enabler for innovation. If you're tired of being the "no" person and want to be the "here's how we make it work securely" person, keep reading.

What You'll Own

As our Senior Product Security Engineer, you'll be the go-to person for all things application and product security. This isn't a checkbox role - you'll shape how we build, ship, and secure our products.

Your Focus Areas:

• Secure SDLC: Build security into our development lifecycle without slowing teams down
• Threat Modelling: Think like an attacker, build like a defender
• DevSecOps: Automate security so developers can focus on building
• AI Security: Secure our AI/ML systems against novel threats and ensure responsible AI practices
• Security Tooling: Choose, implement, and optimize tools that actually work
• Pen Testing & Red Team Coordination: Partner with offensive security teams to validate our defenses
• Controls & Assurance: Ensure security controls are adopted and effective, not just documented
• Partnership: Be the security person developers actually want to talk to

What We're Looking For

Technical Skills:

• Deep understanding of application security vulnerabilities and fixes
• Hands-on experience with security tooling (SAST, DAST, SCA, container security)
• Strong grasp of cloud security (AWS/GCP)
• Experience with GitLab CI/CD pipelines and security integration
• Understanding of AI/ML security risks and mitigation strategies
• Experience building and scaling DevSecOps programs
• Threat modelling expertise that translates to real defenses
• Experience coordinating pen tests and translating findings into actionable improvements

The Human Side:

• You speak developer - you understand their challenges and pressures
• You build bridges, not walls
• You can explain complex security concepts without the jargon
• You're energized by ambiguity and love solving new problems
• You want to own outcomes, not just activities

Why This Role Matters

We're not building another app - we're building technology that thinks and learns. The security challenges are unique, the stakes are high, and the opportunity to shape something meaningful is real. You won't be securing yesterday's technology; you'll be defining security for tomorrow's AI-powered world.

What Success Looks Like

• Developers seek your input early and often
• Security issues are caught in design, not production
• Our AI systems are secure by design, not by accident
• Red team findings decrease over time because we're fixing root causes
• Our security posture scales with our growth
• You've built a security culture, not just security gates

What you will get out of it

• Competitive base salary with additional performance incentives.
• Coverage under the company’s collective health insurance plan.
• Hybrid work model & extra personal/flex days and paid volunteer days a year for your favourite cause.
• Company-sponsored team-bonding events.
• Weekly health & wellness activities, gym discounts, healthy breakfast, snacks and beverages.
• Entrepreneurial culture and amazing coworkers!
• Opportunities to develop new skills and progress your career in a highly multicultural team within a global organization.

Ready to Build With Us?

If you're tired of playing defense and want to build world-class security into cutting-edge products, we want to hear from you. This is your chance to own product security for something that matters.

Join us in building the future - securely.
