Software Engineer in Test (SDET) - Remote First

About the role

Clara, a Latin American payment platform, is hiring a Fullstack/Backend Engineer focused on QA automation, described as an engineering craft role closer to SDET / SET / platform engineer than manual QA. You will build and maintain the systems behind Clara's QA platform: Playwright-based frameworks, services and APIs for test execution and reporting, CI wiring, and internal tools such as test case and run persistence on a React/Next stack. The role is remote first, with in-person ramp-up and occasional team events.

Key responsibilities

• Design and implement shared web/API automation frameworks and libraries (Playwright preferred) with stable selectors, modular architecture and extension points for pods.
• Build backend APIs and fullstack components that store test cases, record run results, expose reports and integrate with delivery workflows (Linear webhooks, Slack notifications, GitHub Actions).
• Structure frameworks and contracts so agents and CLIs can generate and run specs reliably (ticket to runnable tests to evidence).
• Implement and harden smoke and regression pipelines, reduce flakiness and make failures diagnosable.
• Treat automation as a first-class codebase: reviews, tests for helpers, versioning, documentation and refactoring.
• Work with QA engineers on adoption and with product engineers on testability (APIs, data-testid / ARIA, environments, test data hooks).

Required profile

• 4+ years of software development experience (backend and/or fullstack) with automation or developer-tooling delivery.
• Experience building and maintaining test automation frameworks (web and API), and knowledge of the test pyramid.
• Backend fundamentals: REST APIs, relational databases, authentication basics, clean service boundaries.
• Fullstack comfort for internal tools (React / Next.js) is a strong fit.
• Good written and spoken English; Spanish is a plus.

Required skills

• TypeScript/JavaScript for Playwright (or equivalent E2E framework) and Java / Spring Boot where needed.
• CI/CD (GitHub Actions or similar), Docker familiarity, Git.
• Nice to have: prior SDET / SET experience, mobile automation (Appium) or BrowserStack, workflow orchestration (n8n), Linear/GitHub API integrations, AWS and observability basics, fintech domain exposure.

What we offer

• Competitive salary and stock options (ESOP) from day one.
• An annual learning budget and accelerated development paths.
• Remote-first work with in-person ramp-up and team moments.
