How do you make our customers happy?

Every day, thousands of systems, applications, and analytical processes interact with highly sensitive datasets: from customer information to operational metrics to partner integrations. You help secure all of it.

You ensure that data is collected, stored, processed, transported, and deleted according to its value and associated risks, without slowing down the pace of innovation. You help design and build guardrails that engineers want to use because they are robust, automated, and aligned with how modern development teams work.

The biggest challenge

In a world where data moves freely between microservices, cloud providers, warehouses, and ML pipelines, the attack surface grows exponentially. Sensitive information is everywhere, and adversaries know it.

Your challenge: keep our data secure even when it is highly distributed, rapidly transforming, and consumed by an ever‐expanding ecosystem of applications and partners

What you will do as Data Security Engineer

In this role, you are the data protection security engineer inside our multidisciplinary security operations team.

• Perform deep‐dive reviews of data flows and products, storage architectures, ETL pipelines, streaming systems, APIs, and cloud‐native data platforms part of GCP
• Design and implement data security controls tailored to the value and sensitivity of the data (classification‐driven security).
• Engineer end‐to‐end encryption strategies, including envelope encryption, HSM/KMS integrations, key rotation automation, and secrets management for high‐throughput systems.
• Define and deploy tokenization, pseudonymization, masking, and data minimization controls—knowing when each is fit for purpose.
• Contribute to state‐of‐the‐art detection engineering, spotting early‐stage data exfiltration attempts or misuse.
• Work closely with data engineering, analytics, and ML platform teams to embed security into data everything we do.
• Collaborate with cloud engineering teams on identity‐aware data boundaries, access controls, and dynamic authorization in complex, cloud native setups.
• Make data‐security automation a default—CI/CD checks, IaC security patterns, automated classification, policy‐as‐code, and self‐service guardrails.

Why you can make a difference

As a security engineer, you live and breathe data. You understand that not all data is equal and that controls must match the risk, value, and lifecycle of the data, without burdening teams unnecessarily.

To thrive in this role, you bring experience with cloud-powered, data-heavy environments such as analytics platforms, microservices ecosystems, or AI/ML pipelines. You possess a solid understanding of encryption, key management, secrets management, access control models, and secure data architectures. Furthermore, you are familiar with cloud-native data solutions, preferably within GCP, and you are proficient in Python or similar scripting languages.

However, more important than the exact tech stack is your mindset. You are naturally collaborative, curious, pragmatic, and always ready to dive deep.
