Senior Fullstack Engineer — Remote

LATAM

Senior Fullstack Engineer

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

Clara’s Hybrid Policy

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.
