Senior Security Engineer

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
