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".
At CloudWalk, we're not just building products—we're crafting the future of payments.
If you've faced challenges head-on, built solutions from scratch, and thrive on breaking limits, you're speaking our language. Welcome to the Wolfpack.
Why CloudWalk?
We are one of the world's fastest-growing fintechs, but we're not just about growth—we're about impact. We've transformed how millions of businesses handle payments, combining cutting-edge technology, a passionate team, and an audacious vision.
We're building a company for those who crave purpose over prestige. For engineers who want their work to shape the future, not just line the pages of a résumé. If you dream of being part of something bigger than yourself—a team that challenges convention and creates solutions with meaning—then CloudWalk might just be your calling.
The Role
As a Principal Software Engineer, you won't just code—you'll be an architect of systems, a mentor for teams, and a driving force in our mission. This is a role for builders, visionaries, and relentless problem solvers who refuse to settle for "good enough."
Your work will define the foundation of scalable, reliable, and future-proof solutions that empower millions of businesses globally. This isn't management by hierarchy—this is leadership by action.
What You'll Do:
Architect Systems That Last: Design and implement complex, distributed systems that balance scalability, reliability, and simplicity. You'll actively code and ensure the architecture isn't just theoretical but practical.
Own the Journey: Lead projects end-to-end, from discovery to delivery. You'll identify problems, create solutions, and ensure the team crosses the finish line.
Drive Standards of Excellence: Define what "good" looks like, enforce it through best practices, and mentor others to uphold it.
Tackle the Hard Problems: Dive into ambiguity, uncover clarity, and build solutions that stand the test of time.
Mentor, Inspire, Lead: Lift those around you by sharing your knowledge, conducting meaningful reviews, and guiding the next generation of engineers.
Leverage AI and Automation: Use the latest tools and technologies to supercharge productivity, streamline processes, and push boundaries in efficiency.
Who You Are:
You are not just a software engineer—you're an innovator who thrives on turning complexity into simplicity. You're deeply technical, but your impact goes far beyond the codebase.
10+ years of hands-on software engineering, building distributed systems and solving high-scale challenges.
Proven experience in technical leadership, shaping both architecture and the engineers around you.
A "builder's mindset"—you're as comfortable creating solutions from scratch as you are refining existing systems.
Relentless problem solver who thrives on ambiguity and complexity.
Deep understanding of modern software architecture, from microservices to system design.
Experience mentoring teams, leading by example, and fostering a culture of learning.
Advanced proficiency in AI-driven tools and automation for software development.
Advanced English skills to collaborate with our global team.
What You Will Find Here:
Impact at Scale: Your work will directly affect millions of merchants.
Freedom to Build: We embrace creativity and experimentation. Take risks. Fail fast. Learn and iterate.
A Culture of Excellence: We are relentless about raising the bar, and we expect the same of you.
Global Team, Shared Vision: Join a diverse, talented group united by ambition and purpose.
The Wolfpack: At CloudWalk, you're not just an employee—you're part of a pack that has your back.
Diversity and Inclusion at CloudWalk:
We're committed to building a workplace that reflects the diversity of our customers and communities. CloudWalk welcomes and celebrates people of all backgrounds, ensuring every CloudWalker can thrive authentically.
