Senior Front End Engineer

About the role

You are a Senior Front End Engineer who will join Tech Brasil, a small but strategic team responsible for key technology initiatives in Brazil. Your initial focus will be Kuna (our automotive financing product with auto equity and car loans), but you will soon expand to other critical projects. Kuna is Kavak’s fintech vertical, where we build financial products for origination, credit, payments, collections, scoring, back office, and core integrations.

Contract type: full‑time, CLT.

Responsibilities

Develop and iterate on Kuna: auto equity and car loans for Brazil

Write clean, maintainable, well-documented code (React/Angular)

Collaborate in weekly/biweekly planning sessions to break down deliverables with the team

Backend-frontend integration: API consumption, data flows, services

Contribute to both layers: frontend with UX/UI and backend when needed (we are generalists)

Maintain constant communication with stakeholders in Argentina and Brazil (demos, presentations, technical consultations)

Requirements

6+ years of professional experience in React or Angular

UX/UI sensibility: you understand the interface is not cosmetic, it’s functionality and experience

Backend awareness: even as a frontend engineer, you understand architecture, APIs, data flows, and how services integrate

Java + Spring Boot (or a clear willingness to learn quickly)

Frontend-backend integration: working with REST APIs, consuming services, state management

Git and team workflow practices

Active use of AI tools in your daily workflow (Claude Code, Copilot, or others)

Native Portuguese and fluent Spanish or English

Plus

Experience in fintech, lending, payments, credit scoring, or collections.

Core Competencies

Ownership: You take full responsibility for your work. You seek solutions without waiting for permission.

Speed and Resilience: Kavak moves fast. We need people who thrive at a quick pace and don’t freeze. You can deliver even if everything isn’t perfect when the market needs it now.

Autonomy: We work in a small team. You must self-direct, self-evaluate, identify what’s missing, and take action.

Intellectual Curiosity: You ask questions, research, and don’t accept obvious solutions. You care about understanding why things are done a certain way.

Clear Communication: You explain technical decisions to non-technical people. You receive feedback without defensiveness. You document what matters.

Ability to work in ambiguity.

Adaptability.
