We are democratizing the payments industry in Brazil, by empowering entrepreneurs through technological, inclusive, and life-changing solutions.
Based in Brazil, CloudWalk is a high-end global payment network built on modern technology and proprietary blockchain, focused in bringing a revolution to the payment ecosystem for small and medium-sized businesses. As a unicorn, the company has provided its customers with more than R$ 1 billion in savings by charging fair fees on its transactions and is now present in more than 300.000 businesses across 5.000 brazilian cities.
With investors such as the Valor Capital Group, HIVE Ventures and Coatue, the company has already raised US$ 365.5 million in investments and R$3.4 billion in FDICs for anticipation of receivables in its network of financial solutions. In 2022, it was the only brazilian fintech to be featured in the "The Retail Tech 100" ranking by CB Insights, on the "Protection Solutions for Payments and Frauds".
We're not here to waste your time, so we'll skip the corporate poetry.
The Truth
At Cloudwalk, we're not looking for another "AI specialist" to check boxes. We're building something audacious: a fully autonomous, self-driven company powered by a collective of AI agents that YOU will help create.
This isn't about tweaking prompts on off-the-shelf models. This is about architecting digital intelligence from the ground up.
What You'll Actually Be Doing
Creating Intelligence: Building sophisticated agents from scratch using whatever technology gets the job done. No constraints, no bureaucracy – just pure creation.
Orchestrating the Collective: Designing multi-agent systems that communicate, collaborate, and execute complex operations with minimal human intervention.
Evolving the Core: Developing and integrating Model Context Protocols (MCP) that elevate our agents' capabilities beyond current limitations.
Ruthless Automation: Identifying and obliterating inefficiencies in our workflows through intelligent automation that actually works.
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.
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.
The Fine Print
Yes, we'll require a technical assessment. If that bothers you, this isn't your place.
We welcome diversity in all forms – the only discrimination here is against mediocrity.
Apply if you're ready to build something that matters.
