About the Role
We're looking for a Senior QA Automation Engineer 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 an engineer who's passionate about quality and believes the best way to achieve it is by empowering every engineer to test better.
At E2, 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 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
-
Participate in on-call & incident response - Troubleshoot production issues using logs, metrics, and observability tools; investigate services and infrastructure, identify or narrow down root causes, perform appropriate operational actions, and escalate incidents to the right owning team with clear technical context.
-
Shift quality left — Help engineers catch issues earlier through better design, testability coaching, and fast feedback
What We're Looking For
Technical
-
3 - 5+ years as a QA Automation Engineer
-
Strong programming skills— able to write production-grade, maintainable code, not just test scripts. Proficiency in at least one modern programming language (e.g., Java, JavaScript/TypeScript, Python, Dart) and the ability to quickly adapt to others for QA tooling.
