QA Engineer

Required skills

Requirements

3-5 years of software quality assurance experience
Strong focus on test automation architecture
Proactively hunt for corner cases, race conditions, and data leaks across system interactions, utilizing observability tools (logs and metrics) to diagnose root causes
Experience guiding engineering teams through adopting strict input validation practices, moving beyond happy path testing to cover unexpected customer and partner inputs
Experience building or extending automated testing frameworks (e.g., Python, JavaScript/TypeScript, Go, etc.)
Experience with automated back-end/API testing and embedding test suites into CI/CD pipelines
Experience testing microservices, complex APIs, back-end logic, and asynchronous data flows
Proficiency with cloud environments (AWS, Azure and/or GCP), including log analysis, metrics monitoring, and system architecture navigation
Understanding how Crypto Assets work and their properties
Ability to prioritize testing efforts based on risk, business impact, and system criticality
Strong communication skills in both spoken and written English, for documentation and technical specs, and Portuguese, for daily operations

Help the engineering team validate system interactions to mitigate error handling failures, corner case scenarios, data leaks, and other architectural vulnerabilities
Take ownership of the quality, security, and performance strategy for our cloud-based platforms
Operate at the intersection of modern cloud infrastructure and cutting-edge crypto components (e.g., Bitcoin, Liquid Network), increasing availability, minimizing operational risk, and automating everything possible
Design, implement, and maintain automated testing frameworks for functional, regression, integration, and end-to-end testing
Integrate automated test suites into IaC and CI/CD pipelines, ensuring quality gates for all deployments
Use observability tools (e.g., metrics, logs, alerts, dashboards, etc.) to investigate test failures, isolate defects, and collaborate on permanent fixes
Define test plans and quality benchmarks aligned with SLI/SLO targets to support production readiness
Conduct code reviews for automation scripts and promote quality best practices across the engineering team
