Software Engineer in Test (SDET) (Ingeniero de Software en Pruebas) - Remote First

Clara is the leading platform in Latin America for companies to execute and manage every payment operation.

Fullstack/Backend Engineer focused on QA Automation

— a software engineer who builds the infrastructure, frameworks, APIs, and tooling that make automated quality possible at Clara. This is an engineering craft role (closer to SDET / SET / platform engineer than classic manual QA): you write production-grade code that enables pods and QA to generate, run, and trust automated tests.

About Clara

More than 50,000 leading and fast-growing businesses run on our corporate cards, bill pay, financing and B2B payments, and in 2025 the Financial Times named Clara the region’s fastest-growing company. We’re passionate about helping every company we work with become more effective—and, through that, raising the region’s competitiveness. We’re ~400 people, backed by Notable Capital, Coatue, Kaszek, monashees, DST Global, ICONIQ, General Catalyst and Goldman Sachs, among others.

Responsibilities

• You build and maintain the systems behind Clara's QA platform: Playwright-based frameworks, services and APIs that support test execution and reporting, CI wiring, and internal tools (e.g. test case / run persistence on Clara's React/Next stack). You collaborate with the QA Automation Lead, Pod Leads, and product engineers so automation is reusable, agent-ready, and owned as real software — not a pile of brittle scripts.
• Design and implement shared frameworks and libraries for web/API automation (Playwright preferred), with stable selectors, modular architecture, and clear extension points for pods.
• Tooling & services
• Build backend APIs and fullstack components that store test cases, record run results, expose reports, and integrate with delivery workflows (e.g. Linear webhooks, Slack notifications, GitHub Actions).
• Enablement for AI-assisted QA
• Structure frameworks and contracts so agents and CLIs can generate and execute specs reliably (ticket → matrix → runnable tests → evidence).
• CI/CD for quality
• Implement and harden pipelines for smoke and regression suites; reduce flakiness; make failures diagnosable.

Engineering quality of test code

• Treat automation as a first-class codebase: reviews, tests for helpers, versioning, documentation, and refactoring for maintainability.
• Work with QA engineers on adoption and with product engineers on testability (APIs, data-testid
• / ARIA, environments, test data hooks).
• Stronger software engineering depth than a traditional QA Engineer JD (services, APIs, data models, frontend for internal tools).
• Focused on

enabling

• automation at scale — not owning all manual exploratory testing for every pod.
• Builder mindset: you ship frameworks and tools that other engineers adopt.

Requirements

• 4+ years of software development experience (backend and/or fullstack), with demonstrable automation or developer-tooling delivery.

TypeScript/JavaScript

• for Playwright (or equivalent E2E frameworks) and willingness to work in Clara's backend stack (
• Java / Spring Boot) where services or integrations require it.
• Experience building and maintaining

test automation frameworks

• (web and API); understanding of the test pyramid and when to prefer API vs UI coverage.
• Backend fundamentals: REST APIs, relational databases, authentication basics, and clean service boundaries.
• Fullstack comfort for internal tools: React / Next.js (or similar) for dashboards and test-management UIs is a strong fit with Clara's internal scaffold direction.
• CI/CD experience (GitHub Actions or similar), Docker familiarity, and Git-based collaboration.
• Ability to debug flaky tests, environment issues, and integration failures systematically.
• Clear documentation and communication with QA and product engineering partners.
• Comfortable with ambiguity and iterating from working prototypes to reliable platform pieces.
• Collaborative code review habits; you raise the bar on test-code quality.
• Good English (written and verbal); Spanish is a plus.
• We own everything we do, end to end. When something needs to happen, we don't wait.
• We adapt fast, embrace change, and keep learning.

Preferred

• Prior SDET / SET / Test Infrastructure Engineer experience.
• Mobile automation (Appium) or BrowserStack.
• Workflow orchestration (n8n), Linear/GitHub API integrations, or AI/agent tooling for test generation.
• AWS and observability basics for running automation reliably in shared environments.
• Fintech / payments domain exposure.
• Experience replacing external test-management tools with internal systems.

Benefits

• This is a remote-first role: you'll work from home day to day. You'll ramp up in person with the team, and come together in person for team moments, events and customer visits through the year.
• Why Clara

A high talent-density team

• driven to make an impact in Latin America — low ego, high ownership.
• Competitive salary and stock options (ESOP) from day one.
• An annual learning budget and accelerated development paths.
• English is our working language, with Spanish and Portuguese every day.

Pride

• Diverse ideas, stories and perspectives build a better Clara.
• If you meet the must-haves, apply — the nice-to-haves are a bonus, not a requirement.

How we work

Clarity

— Open and direct communication: we say what we mean and give context where it matters.

Simplicity

— If it can be simpler, it should be.

• We hold ourselves to a high standard, and it shows in what we deliver.
