About CloudWalk:
We are not just another fintech unicorn. We are a pack of dreamers, makers, and tech enthusiasts building the future of payments. With millions of happy customers and a hunger for innovation, we're now expanding our neural network - literally and metaphorically.
About the role: You'll be architecting AI agents that handle real-world financial transactions at scale, building autonomous systems that need to be both intelligent and bulletproof. We're not looking for another "AI specialist" to check boxes—we're building something audacious: digital intelligence from the ground up. Whether you're passionate about applied machine learning, obsessed with robust agent architectures, or skilled in building high-performance distributed AI systems. If you dream in intelligent solutions and see autonomous agents as art, this is your canvas.
What You'll Actually Be Doing
- Build & Ship: Develop, test, and deploy backend features and APIs in Elixir, ensuring code serves millions of users safely and efficiently.
- Craft Experiences: Design reliable backend systems and intuitive APIs that make complex financial operations robust and seamless for our customers.
- Solve & Optimize: Investigate and resolve issues while continuously improving performance, concurrency, and scalability across our distributed systems.
- Collaborate & Plan: Participate in feature planning, estimation, and scoping alongside product and engineering teams to deliver impactful solutions.
- Mentor & Learn: Review pull requests, pair program with teammates, and contribute to our engineering culture of continuous improvement.
Who We Need
- Engineering Excellence: Python mastery is expected, flexibility with other languages as well.
- Deployment Warrior: You don't just build – you ship. CI/CD, infrastructure, and keeping complex AI systems running in production are second nature to you.
- Problem Obsessed: You don't clock out when things get difficult. You're the type who loses sleep over unsolved puzzles and wakes up with solutions.
- Framework Fluent: Experience with RAG pipelines, LangChain/LangGraph, and integration with major LLM providers (OpenAI, Anthropic, Google) isn't just preferred – it's required.
- Bullshit Allergic: You value direct communication, tangible results, and spend zero energy on corporate theater.
- Portuguese Fluency: Fluent Portuguese communication isn't optional – our agents work with Portuguese-language data and clients daily. You need to think, debug, and communicate seamlessly in Portuguese.
Why Cloudwalk?
- Real Autonomy: We hire smart people and get out of their way. Your ideas won't die in committee.
- Elite Team: Work with a compact group of brilliant engineers who share your intensity and distaste for the conventional.
- Actual Impact: Your code won't be gathering dust in some repository – it will reshape how financial systems operate, starting in Brazil and expanding globally.
Join us at CloudWalk, where we’re not just engineering solutions; we’re building a smarter, AI-driven future for payments—together.
