Why should you join dLocal?

dLocal enables the biggest companies in the world to collect payments in 40 countries in emerging markets. Global brands rely on us to increase conversion rates and simplify payment expansion effortlessly. As both a payments processor and a merchant of record where we operate, we make it possible for our merchants to make inroads into the world’s fastest-growing, emerging markets.

By joining us you will be a part of an amazing global team that makes it all happen. Being a part of dLocal means working with 1000+ teammates from 30+ different nationalities and developing an international career that impacts millions of people’s daily lives. We are builders, we never run from a challenge, we are customer-centric, and if this sounds like you, we know you will thrive in our team.

dLocal processes billions in payments across 40 emerging markets. The infrastructure behind that runs fast, runs globally, and runs on engineering teams that do not have patience for security that slows things down. Neither do we.

Our security function is lean by design and automation-native by philosophy. We have built a modern stack, a senior team, and a culture where security engineers are expected to think like builders, not gatekeepers. The CISO's mandate is simple: safely accelerate the business. Everything we build is oriented around that.

This role is the technical backbone of our defensive infrastructure layer. You will own the detection, defensive security platforms and cloud security engineering that every other security team depends on. You will work across a wide ecosystem: Cyber Detection & Response, Cloud & Platform Security, Application Security, Offensive Security, IAM, and our Security Automation & AI team internally, and Cloud Platforms, SRE, DevOps, Network, and CI/CD teams on the engineering side.

That cross-functional surface area is intentional. This is not a role where you sit inside a tool and tune rules. You will be the person who connects posture signals to response workflows, translates every security requirement into engineering backlogs and builds the infrastructure that makes the rest of the security organization measurably faster.

If your instinct when you see a manual process is to automate it before the week is out and you get genuinely energized by owning hard infrastructure problems end to end, this is built for you.

Requirements

~2 min read

Solid knowledge across multiple security domains like CDR, Cloud Security, AppSec, Offsec, etc

Experience with Security Platforms, AI agents, LLM APIs and automation frameworks. If you are not there yet, you are actively building it.

Familiarity with threat intelligence platforms and integrating intel into detection pipelines.

MDR vendor co-management experience.

Prior involvement in purple-team or red-team exercises.

Certifications (GCIA, GCFA, OSCP, AWS Security Specialty) are valued but secondary to what you have built and shipped.

High ownership. No queue to wait in.

You will interface daily across Cyber Detection & Response, Cloud & Platform Security, AppSec, IAM, Offensive Security, and the Security Automation & AI team. On the engineering side, you will work regularly with Cloud Platforms, SRE, DevOps, Network, and CI/CD teams. The surface area is wide and the problems are real.

The CISO's office operates on one principle: security is a business enabler. You will have executive sponsorship and the political cover to make pragmatic trade-offs. What you will not have is the option to move slowly or hide behind process.

If you want to own infrastructure that actually matters, work with a team that respects engineering craft, and build in an environment that moves at the speed of the business, this is the right place.
