[Hiring] Senior Software Development Engineer in Test @Aplazo

Role Description

We're looking for a Senior SDET (Software Development Engineer in Testing) to elevate engineering quality across Aplazo. This is an engineering role—you'll write production-grade code and maintain automated tests independently; improve existing suites and coverage in your own area, adapt and improve test plans for medium/large features, execute end-to-end with little guidance and give clear feedback to engineers on quality.

You're not a QA gatekeeper. You're an engineer who's passionate about quality and believes the best way to achieve it is by empowering every engineer to test better. You'll build the tools, frameworks, and practices that make quality a natural part of how we work. You lead quality initiatives for your squad and mentor engineers on testing practices.

What You'll Do

• Mentor engineers on quality — Pair with engineers to improve their testing practices; TDD, and test design
• Own test strategy — Define testing approaches (unit, integration, contract, e2e) for your squad
• Write code — Build production-grade automation, testing tools & test scripts
• Drive quality metrics — Instrument and track quality signals (coverage, flakiness, test times, defect rates); use data to prioritize improvements
• Leverage AI for quality — Use AI to generate tests, identify coverage gaps, and accelerate quality feedback loops
• Shift quality left — Help engineers catch issues earlier through better design, testability coaching, and fast feedback

Qualifications

• 3 - 5+ years as a software engineer or SDET
• Strong programming skills—you will write production code, not just test scripts (Java, selenium, cucumber, Appium (for mobile test), RestAssured (for API testing))
• Deep expertise in test architecture: unit, integration, contract, and e2e testing strategies
• Proficient with CI/CD, integration and test automation with Jenkins pipelines and GitHub Actions for solution builds and deployments.
• Familiar with our stack or similar: Java/Spring, Angular/Flutter, AWS, PostgreSQL, MongoDB, Datadog, Postman, Bruno and JMeter

Requirements

• Uses AI tools to generate test cases, identify edge cases, and accelerate test development
• Applies AI to detect flaky tests, analyze coverage gaps, and prioritize testing efforts
• Builds or champions AI-powered quality tools for the team
• Stays current on AI-assisted testing capabilities and best practices

Benefits

• Believes engineers should own quality—your job is to enable them, not replace them
• Thinks about testability during design, not just after implementation
• Pragmatic about test coverage—you optimize for confidence
• Understands testing and when to break the rules
