Location & Work Model

Our technology team operates under a "remote-first" model, which means we work from home and can live anywhere in Brazil. We also offer the option of working from our São Paulo office. Furthermore, we offer the Work From Anywhere program, allowing you to work from any country for up to 90 days a year, ensuring you have the flexibility to do the best work of your career.

The Role

As a Senior Software Engineer, you will be a core driver of our technical execution. Here, you won't just "maintain old systems" or "take tickets." We are an organization of builders guided by deep technical density. You will use our Leadership Principles, like Dive Deep and Make it Great, to solve high-impact distribution problems and build the systems of our next decade.

We believe that technology scales execution, but senior talent scales judgment. You will be at the forefront of our AI-First pivot, designing highly scalable, resilient systems capable of supporting low-latency conversational journeys, heavy microservices orchestration, and real-time ML processing.

Our Tech Stack: We work with Java, Kotlin, Node.js, Go, Python, React, and more, primarily hosted on AWS. Our daily workflow also incorporates various AI tools, including Claude Code.

Don't worry if you haven't mastered our exact stack. We value strong problem-solving skills, adaptability, and an engineering mindset over specific technology experience.

Position & Technical Challenges

We hire Senior Software Engineers through a unified selection process for multiple engineering teams.

At the final stage, you'll have the opportunity to explore which team best matches your experience and interests, alongside our hiring needs.

End-to-End Ownership: Be responsible for the entire software development lifecycle: definition, development, testing, production, and maintenance. Adopt an "owner's mindset", creating observability and taking proactive actions on post-mortems.

Quality Guardian: Be a guardian of your team's delivery quality by reinforcing the adoption of excellent software development practices, participating rigorously in code and design reviews.

Mentorship: Mentor mid-level and junior engineers, raising the technical bar of your team and sharing knowledge across our teams.
