The Role:
We’re seeking a Senior Application Security Engineer who is first and foremost a teacher, advisor, and enabler for our development teams. Rather than owning security alone, you’ll embed secure-by-design thinking across engineering by mentoring developers, guiding architecture decisions, and making secure development intuitive and frictionless. You’ll serve as the go-to partner for developers and engineering leaders, offering clear direction, practical solutions, and hands-on mentorship that strengthens our secure SDLC.
Who You Are:
* A proactive self-starter with deep expertise in application and cloud security
* Passionate about secure development and enabling engineers through thoughtful guardrails
* Clear and confident communicator who can influence across technical and non-technical teams
* Curious about emerging threats and excited by the challenges of blockchain security
* Committed to excellence, with a strong sense of ownership and a drive to build secure systems that scale
What You’ll Actually Be Doing:
* Mentor, coach, and educate developers on secure coding through workshops, training sessions, pair reviews, and ongoing guidance
* Lead and scale a Security Champions program embedded within engineering teams
* Facilitate threat modeling sessions and design reviews, partnering with teams early in the process to improve security outcomes
* Collaborate with engineering leadership to ensure secure architecture patterns, API security practices, and design principles are built in from day one
* Integrate and tune developer-friendly AppSec guardrails into CI/CD pipelines (SAST, SCA, IaC, secret scanning) while minimizing noise for developers
* Translate vulnerabilities into clear, actionable remediation guidance that developers can easily implement
* Support security awareness across engineering by building engaging internal content, best-practice playbooks, and reusable patterns
* Partner with compliance teams to produce documentation and SDLC evidence supporting FFIEC, PCI DSS, and SOC 2 requirements
* Stay current on emerging threats, developer tooling, and secure engineering patterns — sharing insights regularly with the team
Why You’ll Love Working Here:
* Flexible hybrid model: 3 days a week in the office – A must
* ₪1,000 net monthly wellness benefit – from therapy to Pilates to your kid’s art class
* Full Keren Hishtalmut, private health & dental insurance
