We already help over 20,000 large and growing businesses operate with agility and financial clarity through locally issued corporate cards, bill pay, financing, and a powerful B2B platform built for scale.

Clara is backed by some of the most successful investors in the world, including top regional VCs like monashees, Kaszek, and Canary, and leading global funds like Notable Capital, Coatue, DST Global Partners, ICONIQ Growth, General Catalyst, Citi Ventures, SV Angel, Citius, Endeavor Catalyst, and Goldman Sachs - in addition to dozens of angel investors and local family offices.

We’re building the financial infrastructure that powers high-performing organizations across the region. We invite you to join us if you want to be part of a fast-paced environment that will accelerate your career and support you to do some of the best work of your life alongside a passionate and committed team distributed across the Americas.

LATAM

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

Why join Clara

At Clara, you’ll have the autonomy, speed, and support to make meaningful impact — not just on your team, but on how organizations are run across Latin America.

Multicultural team with daily exposure to Portuguese, Spanish, and English (our corporate language)

Annual learning budget and internal accelerated development paths

High-ownership environment: we move fast, learn fast, and raise the bar — together

Smart, ambitious teammates — low ego, high impact

Flexible vacation and hybrid work model focused on results

Claridians in a hybrid mode split their time between working from the office, talking to or visiting customers, or working from home. This hits a balance between bringing people together for in‑person collaboration and learning from each other, while supporting flexibility about how to do this in a way that makes sense for each individual and team.

We don't enforce a minimum number of days for most roles, but you're expected to spend time at the office organically, and be at the office most days during your ramp‑up or when required by your leader.
