We're hiring a Senior Security Engineer to help shift security left across product and platform teams, while also supporting internal corporate security needs. You'll drive impact through enablement, automation, and practical risk reduction.

Why this role matters

You'll 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; it's a force multiplier. You'll 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
You might be a fit if you:
  • See security as an enabler of speed, not an obstacle
  • Are comfortable in cloud and on-prem worlds
  • Value autonomy, and naturally take ownership from idea to execution
  • Can zoom out to prioritize risks and zoom in to fix root causes
  • Communicate clearly with devs, ops, and business teams alike
  • Eager to work in a technically challenging environment
You'll grow by working with:
  • Terraform, Docker, Kubernetes
  • Modern security tools
  • GitHub Actions, Jenkins
  • AWS, Azure, GCP
  • Teams building external-facing services (web apps, APIs) and internal platforms (CI/CD, admin tooling) to embed security by design.
  • Supporting a public company environment with compliance requirements across multiple standards, including SOC 2 and ISO 27001
Skills that help (we'll support your growth):
  • Application Security: code review, threat modeling, WAF
  • CloudSec: IAM, policy-as-code, workload hardening
  • On-Prem/Corporate: endpoint protection, monitoring and production access control
  • Communication: making risk visible and actionable
The Team Environment

You'll 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. You'll 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

Life at Teads

At Teads, we don't just offer new roles - we blend creativity, technology, and data to shape the future of media. You'll work with smart humans, meaningful brands, and cool tools, all while helping redefine how advertising works in a world that demands more transparency, better insights, and smarter strategies.

As a Teadster, you'll play a critical role in shaping our future success in the region. Here's why Teads stands out:

  • We've merged two open internet category leaders—Outbrain and Teads—to create the 'new' Teads, a unified omnichannel platform that drives results from branding to performance across all screens, including CTV, mobile, and web.
  • As part of our team, you'll thrive in a collaborative and forward-thinking environment that fosters innovation, creative problem-solving, and continuous learning.
  • Teads is committed to your success, offering the support, tools, and development opportunities you need to excel in your role.

Our company culture is welcoming, dynamic, diverse, global, and built on top performance.

Teads is an equal employment opportunity employer and committed to diversity and inclusion at all stages of recruitment and employment.

Our team is made up of individuals who are approachable, resourceful, passionate, and proactive. We foster a sense of belonging through our Employee Resource Groups – employee-led groups in which we debate topics and drive change: environmental, women empowerment, charitable initiatives to diversity, equity, and inclusion, you'll be able to share your passions with likeminded people.
