Clara is the leading platform in Latin America for companies to execute and manage every payment operation. More than 50,000 leading and fast-growing businesses run on our corporate cards, bill pay, financing and B2B payments, and in 2025 the Financial Times named Clara the region’s fastest-growing company. 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 are
We'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. 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
Nice to haves:
- 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
Where we work
This is a remote-first role: you'll work from home day to day. 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.
If you meet the must-haves, apply — the nice-to-haves are a bonus, not a requirement.
