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.

What You’ll do:

Own and continuously evolve our cloud WAF stack, defining and tuning rules, policies, and traffic flows to protect public APIs and frontends at scale, while proactively reducing noise and false positives.
Build and maintain end‑to‑end HTTP/HTTPS observability, including structured logging, dashboards, alerting, and synthetic checks, so that performance issues, misconﬁgurations, and attacks are detected and triaged early.
Drive WAF and networking infrastructure as code (IaC), fully integrated into CI/CD pipelines, ensuring changes are repeatable, auditable, tested, and secure, and helping to reduce conﬁguration drift across environments.
Design and operate VPCs and core network services (routing, DNS, VPNs, and third‑party connectivity), making sure they are resilient, scalable, and aligned with our global network and security architecture.
Automate key deployment and conﬁguration workﬂows (e.g., onboarding and decommissioning sites, rule and policy lifecycle, failover between WAF providers), minimizing manual work, human error, and operational risk.
Lead and actively participate in incident response for network and WAF‑related security, performance, and availability events, including triggering WAF DRP procedures, executing controlled failovers, and driving post‑mortems and follow‑up remediation.
Partner closely with Information Security and Compliance to ensure the network and WAF architecture meets regulatory and industry standards (e.g., PCI, SOX), providing audit‑ready evidence and continuously strengthening controls.
Keep technical documentation current and actionable for architectures, traﬃc ﬂows, runbooks, and conﬁguration standards, enabling other engineering teams to move fast while maintaining a strong security and reliability posture.

Solid, hands‑on experience managing and conﬁguring WAFs in cloud environments (ideally multi‑provider), protecting high‑traﬃc web applications and APIs.

Strong knowledge of networking and protocols (TCP/IP, HTTP/HTTPS, TLS, DNS, routing, load balancers, VPN/IPsec).

Practical experience with at least one cloud provider (ideally AWS) and its networking components (VPC, subnets, security groups, NACLs, routing, load balancers).

Real‑world experience with Infrastructure as Code (Terraform or similar) and CI/CD pipelines to manage network and WAF changes.

Experience in observability and monitoring: log, metric and trace analysis, building actionable dashboards and alerts (latency, errors, throughput, anomalous traﬃc patterns).

Strong communication and cross‑team collaboration skills (Networking, Security, Platform, Product), with English good enough to document and coordinate in writing and in calls.

English

Would be Awesome if You Had:

Exposure to PCI-DSS framework or any other relevant security standard will be valued;

Good knowledge of security architectures, both monoliths and microservices, including how they are developed and operate at scale;

Good understanding about Machine learning, RAG, and LLM logic in context of security results.

Previous work in high‑criticality environments (payments, ﬁntech, banking, global e‑commerce) where availability and latency are key.

Background as a network/security architect, able to propose end‑to‑end designs (multi‑WAF, multi‑cloud, DRP, zero‑trust, etc.) and explain technical and business trade‑offs.
