Frontend Software EngineerType: Remote ContractLocation: Brazil, Mexico, Chile or ColombiaCoverage: Pacific Time overlap required

Job Description:We are looking for an experienced Frontend Software Engineer to build, maintain, and test features for a large-scale cloud management web console.This is a hands‑on engineering role for someone with strong React and TypeScript experience who is comfortable working in a mature, shared codebase and owning frontend features from requirements through implementation, testing, deployment, and verification.A strong testing discipline is particularly important. Engineers are expected to write unit and integration tests alongside feature development rather than treating testing as a separate or optional activity.You will work closely with engineering and product stakeholders in a distributed environment, integrate frontend experiences with production REST APIs, and build interfaces using established design systems and shared components.

Key Responsibilities:

• Build, maintain, and improve production frontend features using React and TypeScript.
• Develop complex forms, configuration workflows, dashboards, and other interactive application experiences.
• Apply strong React fundamentals, including hooks, state management, component architecture, and reusable patterns.
• Translate product and UI/UX requirements into reliable, maintainable production interfaces.
• Work within an established design system and shared component ecosystem rather than relying primarily on custom styling.
• Contribute to shared frontend components, libraries, tooling, and engineering patterns.

Testing and Software Quality:

• Write unit and integration tests alongside all feature development.
• Build testable frontend components and application logic.
• Maintain and improve existing test suites as functionality evolves.
• Diagnose and resolve regressions, edge cases, and production issues.
• Participate in peer code reviews and incorporate engineering feedback.
• Maintain high standards for code quality, reliability, readability, and maintainability.

APIs and Application Integration:

• Integrate frontend applications with REST APIs in production environments.
• Build user interfaces around complex API-backed workflows and configuration models.
• Handle application state, validation, errors, loading states, and API responses reliably.
• Collaborate with backend engineers when defining or troubleshooting frontend‑to‑service integrations.
• Diagnose issues across the boundary between frontend applications and backend services.

Engineering Delivery:

• Own features from requirements gathering and technical design through implementation, testing, deployment, and production verification.
• Work effectively within large shared codebases with established engineering standards.
• Use Git and pull‑request workflows as part of day‑to‑day development.
• Work within automated linting, testing, build, and CI/CD pipelines.
• Contribute to technical discussions and identify appropriate implementation approaches and trade‑offs.
• Use GenAI‑assisted development tools effectively while maintaining engineering quality and ownership of the resulting code.

Collaboration:

• Work effectively with engineers, product stakeholders, and designers in a distributed environment.
• Communicate implementation decisions, blockers, risks, and progress clearly.
• Participate constructively in code reviews and technical discussions.
• Work independently while coordinating effectively with the broader engineering team.
• Document technical decisions and implementation details when appropriate.

Qualifications:Education and Experience:

• 5+ years of professional frontend software development experience.
• Significant hands‑on experience building production web applications with React and TypeScript.
• Demonstrated experience writing unit and integration tests as part of regular feature development.
• Production experience integrating frontend applications with REST APIs.
• Experience contributing to large, shared production codebases.
• Experience working with Git, pull requests, code reviews, and CI/CD workflows.
• Experience using GenAI‑assisted coding tools as part of the software development process.
• Degree in Computer Science, Engineering, or a related field, or equivalent practical experience.

Technical Skills:

• Strong production experience with React and TypeScript.
• Strong understanding of React hooks, component architecture, state management, and complex forms.
• Strong frontend testing experience, including unit and integration testing.
• Experience consuming and integrating REST APIs in production applications.
• Strong JavaScript and modern web development fundamentals.
• Experience working with established frontend architecture and shared component libraries.
• Strong Git and pull‑request workflow experience.
• Experience with automated linting, testing, build processes, and CI/CD pipelines.
• Ability to debug frontend application issues and identify problems across UI, state, API, and application layers.
• Practical experience using GenAI‑assisted development tools while independently validating and owning generated code.

Preferred:

• Experience working with monorepos.
• Experience building applications using established design systems or component libraries.
• Experience with Node.js, Python, or broader full‑stack development.
• Experience developing GenAI‑powered products or user experiences.
• Experience with complex cloud portals, developer tools, administrative consoles, dashboards, or configuration‑heavy applications.
• Experience improving shared frontend tooling, architecture, or developer experience.
• Experience working in large engineering organizations or mature software platforms.

Soft Skills:

• Strong written and verbal communication.
• High degree of ownership and ability to work independently.
• Comfortable collaborating asynchronously across a distributed team.
• Strong analytical and problem‑solving skills.
• Able to receive and provide constructive code‑review feedback.
• Comfortable working within an established engineering environment and adapting to existing standards and patterns.
• Able to take a feature from an initial requirement through production delivery and verification.

Please Note:

• This is a hands‑on frontend engineering role. We are looking for candidates with substantial production React and TypeScript experience, not primarily UI/UX design or website‑focused backgrounds.
• Writing tests is an expected part of feature development. Candidates should have practical experience writing unit and integration tests for production frontend applications.
• Experience integrating frontend applications with REST APIs and working with complex forms or configuration workflows is important for this role.
• Candidates should be comfortable contributing to an existing large codebase with established linting, testing, code‑review, and CI/CD practices.
• Experience using GenAI‑assisted coding tools is required, but candidates must be able to independently understand, validate, test, and maintain the code they deliver.
• Experience with monorepos, design systems, Node.js/Python, or GenAI product development is preferred but not required.
• This role is currently focused on candidates based in Brazil, Mexico, Chile or Colombia.
