Senior Fullstack Engineer

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.

• 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

• 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. Experience using tools like Claude, Devin, or n8n to automate repetitive or complex engineering workflows
• Strong communication skills and comfort collaborating cross-functionally with Product, Design, and Operations
• Working proficiency in English

• Experience with AWS, Metabase, or Databricks
• Familiarity with SQL or Python for backend or data use cases
• Background in fintech, payments, banking integrations, or credit infrastructure
• A good sense of humor — we work hard and we like to enjoy it

• 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.

• 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.

Claridians split their time between the office, customers and home. We don't set a minimum number of office days for most roles, but we expect you to spend time there naturally, and most days during your ramp-up or when your leader asks.

If you meet the must-haves, apply — the nice-to-haves are a bonus, not a requirement.
