We’re an AI‑first fintech on a mission to rebuild Brazil’s payment infrastructure. Yes, we’re a unicorn — but valuations don’t excite us as much as impact. We obsess over the day‑to‑day challenges our clients face, and we turn advanced technology into elegant and fast financial experiences. If you see data as more than numbers, code as more than syntax, and finance as more than ledgers, CW may be a place for you.

Every feature we ship must be safe, compliant, explainable, and lightning‑fast—all at once. That’s the puzzle we wake up for.
What You’ll Do:
Architect & build resilient, scalable services and data pipelines that keep our financial engines humming.
Infuse intelligence: integrate ML models, LLM agents, and rule engines to automate and sharpen decision‑making.
Own the full lifecycle: from discovery to observability, SRE mandates, and continuous delivery.
Champion quality: drive testing strategies, incident reviews, and operational excellence that earns trust.
What you’ll need:
Initiative to learn, investigate, experiment.
Ability to communicate and debate in English and Portuguese.
Excellent problem-solving and communication skills.
Strong programming skills.

We are committed to fostering a diverse and inclusive workplace. We welcome applicants from all backgrounds to apply.
