Senior Fullstack Engineer — Remote

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
