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.

As a JavaScript/Node.js Technical Referent at dLocal, you will be the senior technical reference for how we design, build and evolve our Node.js services and JavaScript-based platforms and front-end applications.

Your mission is to enable product and engineering teams to take features from idea to production in a reliable, performant and observable way. You will own the technical direction of our JavaScript/Node.js stack – from backend services to client-facing interfaces –, define best practices and architectural patterns, and help the team scale its impact as traffic, complexity and business demands grow.

A core part of this role is to use modern JavaScript tooling and platform capabilities — from Node.js runtimes and frameworks to front-end build systems, rendering strategies, , observability and CI/CD — to automate and standardize how we ship backend and full-stack services. You will work side by side with product engineers, platform teams and architects to make our developer experience fast, safe and efficient.

This is a hands-on architecture and leadership role: you won't own a single product domain yourself, but you will deeply influence how every Node.js service, front-end application, and JavaScript-based component is designed, implemented, tested, deployed and operated in production.

Framework Ownership: Set the technical vision for our internal application framework stack – both server-side and client-side –, defining conventions, project archetypes, and lifecycle management for libraries and tooling.

Front-End Architecture: Define and evolve our front-end stack (React, Next.js, or successor frameworks), establishing patterns for server-side rendering, client-side rendering, and hybrid approaches that balance performance, SEO and developer experience.

Platform Engineering: Design, build, and maintain core platform components mainly in javascript and TypeScript, enabling product teams to ship quality code quickly and safely.

Architecture & Standards: Champion best practices, standards, and review and approve RFCs that impact how we deploy code company-wide. For example: Observability, security, and performance best practices.

Mentorship & Leadership: Serve as technical referent for a multi-disciplinary platform team; coach engineers, run architecture reviews, and foster a culture of continuous improvement.

Cross-Functional Collaboration: Work with Security, and Infrastructure teams to align roadmaps, manage technical debt, and ensure platform capabilities meet business needs.

Continuous Improvement: Track industry trends, evaluate new technologies and pilot innovations that keep our platform ahead of scale and compliance demands.

Bachelor’s degree in Computer Science, Software Engineering, or a related field.

5+ years of professional experience building large-scale backend or platform systems, with deep proficiency in JavaScript/TypeScript. Java professional experience is a plus.

Solid experience with modern front-end frameworks (React, Next.js, or similar), including server-side rendering (SSR), static site generation (SSG), and client/server component patterns.

Good communication skills in English; able to articulate complex ideas to both technical and non-technical stakeholders.

Proven track record designing and operating cloud-native architectures on AWS (EKS, DynamoDB, etc.).

Hands-on knowledge of containerization & orchestration and modern CI/CD pipelines (GitHub Actions, Jenkins, Argo CD).

Strong knowledge of microservices, event-driven architectures (Kafka, SNS/SQS), and REST API design.

Familiarity with observability stacks, agile methodologies, and software security fundamentals.

Experience creating reusable SDKs, libraries, or internal developer platforms.

Experience with AI-Driven Tooling: Demonstrated history of leveraging AI/ML tools and generative AI in daily development workflows to automate tasks, improve code generation, perform intelligent testing, or enhance operational efficiency.
