We’re passionate about helping every company we work with become more effective—and, through that, raising the region’s competitiveness. We’re ~400 people, backed by Notable Capital, Coatue, Kaszek, monashees, DST Global, ICONIQ, General Catalyst and Goldman Sachs, among others. **We're looking for a Senior Fullstack Engineer to join Clara's Integrations team — the squad responsible for connecting Clara's financial platform to the ecosystem of ERPs, banks, payment processors, and enterprise systems that power our clients' operations across Brazil, Mexico, and Colombia.** You'll design and build the integrations, pipelines, and APIs that keep Clara's financial data flowing reliably across dozens of third-party connections. Fullstack here is real — several of our most important upcoming initiatives require building internal tooling and client-facing interfaces from scratch, and you'll be expected to own those end to end. AI fluency is central to how we work on this team — you're expected to use it across the full development lifecycle, from design to deployment, and to reach for it whenever it makes you faster or better. **In this role, you will:** - Design, build, and maintain backend integrations with payment processors, ERP platforms, and financial infrastructure providers across Latin America - Architect scalable, secure, and observable services that handle sensitive financial data with the reliability our clients depend on - Build and own frontend interfaces when the initiative calls for it — internal tooling, integration dashboards, configuration UIs - Use AI tools to automate repetitive engineering workflows, accelerate delivery, and close skill gaps — from scaffolding integrations to generating and reviewing code - Set the technical bar through code reviews, architectural input, and hands-on mentorship of junior and mid-level engineers - Collaborate closely with Product, Design, and Data to translate complex integration requirements into reliable, maintainable solutions - Identify and tackle tech debt that creates operational risk or slows the team down **Who you areWe're looking for someone who meets the minimum requirements to be considered for the role.Must haves:** - 5+ years of backend software development experience, with at least 1–2 years working across the full stack - Strong software architecture and system design skills — you've built systems that scale and fail gracefully - Strong proficiency in one or more backend languages; our primary stack is Java / Spring Boot - Good frontend knowledge in one or more frontend language/framework (our stack is React) - Demonstrated use of AI tools throughout the development process — design, coding, code review, debugging, and documentation.

You'll ramp up in person with the team, and come together in person for team moments, events and customer visits through the year. ### Why Clara - **A high talent-density team** driven to make an impact in Latin America — low ego, high ownership. - Competitive salary and stock options (ESOP) from day one. - An annual learning budget and accelerated development paths. - English is our working language, with Spanish and Portuguese every day. ### How we work - **Clarity** — Open and direct communication: we say what we mean and give context where it matters. - **Simplicity** — If it can be simpler, it should be. - **Ownership** — We own everything we do, end to end. When something needs to happen, we don't wait. - **Pride** — We hold ourselves to a high standard, and it shows in what we deliver. - **ABC (Always Be Changing)** — We adapt fast, embrace change, and keep learning. - **Inclusivity** — Diverse ideas, stories and perspectives build a better Clara.
