Were hiring a Senior Security Engineer to help shift security left across product and platform teams, while also supporting internal corporate security needs. Youll drive impact through enablement, automation, and practical risk reduction.
Why this role matters?
Youll secure both what we build and how we work. That means embedding security into our products and CI/CD, and also supporting internal teams.
Security here is not a gate; its a force multiplier. Youll help engineering teams move faster safely, and ensure our colleagues have a secure foundation to do their best work.
Success means faster, safer releases and fewer reactive security escalations.
What will you do?
As a Senior Security Engineer, your mission will be to:
Partner with developers to embed security into design, build, and deploy stages
Automate vulnerability triage and mitigation flows
Secure CI/CD pipelines (GitHub, Jenkins) and execution environments (Kubernetes, Docker)
Tune WAFs, manage cloud security (AWS, GCP, Azure), and evolve Terraform practices
Support internal teams with secure production accesses, endpoint hardening, and access policies
Lead security reviews across app, infra, and corporate environments
Advocate for security standards with clarity and empathy
The Team Environment:
Youll join a cross-cultural, globally distributed security team that thrives on collaboration, curiosity, and continuous learning. We bring together a wide range of experiences and backgrounds to solve meaningful problems.
We support each other through knowledge sharing sessions, workshops, and async collaboration. Youll have the chance to attend industry conferences, participate in internal guilds, and continuously sharpen your skills using our dedicated security training platform.
How we work:
Autonomy with alignment: own your work, stay connected to purpose
Bias for action: ship, learn, improve
Enablement mindset: security exists to empower teams, not slow them down
Simple and pragmatic: perfect is the enemy of shipped
Please submit your CV in English.

Were 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, youll embed secure-by-design thinking across engineering by mentoring developers, guiding architecture decisions, and making secure development intuitive and frictionless.
Youll 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 Youll 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.
