The future we envision is post-human and post-machinic: symbiotic hybrid beings coexisting and exchanging knowledge and wealth. We aim to anticipate that world as much as possible. Our engineers move fast and see AI agents as their coworkers. We communicate with both humans and machines in a direct and clear manner – no time wasted. The platforms we build scale with the organization, unlocking quality and speed at every level. AI innovations not only enhance the products and services we offer, they transform how we build them. We are building a smarter, AI-driven future for payments. Join us if you, too, envision that future.
About the Role:
- You may work on our main products, such as InfinitePay or Jim, contributing to new features
- You will explore experimental products and features that may or may not reach the market. We take our experiments seriously and strive to learn as much as possible from them, even if they don’t necessarily end up being integrated into a product
What you'll do:
- Turn early production ideas or prototypes into production code
- Write tests to keep reliable, following SecOps and DevOps procedures
- Patch security issues as soon as they appear and release small, safe updates through CI/CD pipelines with near-zero downtime. You own what you build (performance, uptime and maintainability)
- Continuous improvement is expected: take part in product discussions, share what you know and help the team move faster together
What you'll need:
- Solid software development foundation with Python, SQL and JavaScript/TypeScript (Node.js, React)
- Cloud-native architecture experience and familiarity with modern development workflows
- Practical experience with LLMs and AI-assisted development tools and techniques (e.g., using Cursor, OpenAI APIs or similar tools)
- Strong engineering practices including automated testing, observability, resilience, maintainability and application security
- Problem‑solving mindset with clear cross-team communication and collaboration
- Ability to communicate and debate in English and Portuguese
Bonus points if you have:
- Background in high throughput or real‑time systems for handling scale and performance challenges
- Practical exposure to multi-agent frameworks and AI system orchestration
- Experience with game development and virtual simulation
Recruiting process outline:
- Programming assessment
- Technical interview
- Cultural interview
If you are not willing to take your time to work on a test case, do not apply.
Diversity and inclusion:
We believe in social inclusion, respect, and appreciation of all people. We promote a welcoming work environment, where each CloudWalker can be authentic, regardless of gender, ethnicity, race, religion, sexuality, mobility, disability, or education.
