Full Description

SENIOR QUALITY ENGINEERING (QE) - ENGINEER ROLE SUMMARY

We’re hiring a Senior Quality Engineering (QE) Engineer to raise the quality bar through strong test strategy, pragmatic automation, and hands-on delivery in a complex, legacy-heavy environment that is actively modernizing.

This role combines direct ownership of critical quality surfaces with enablement of product engineering teams. While product engineers are expected to own quality within their domains, QE continues to own and maintain certain cross-cutting end-to-end (E2E) and regression workflows that span multiple product areas or represent systemic risk.

You’ll work closely with Product, Engineering, and Manual QA to ensure quality is validated at the right layers, by the right owners, using good judgment rather than rigid rules.

WHAT YOU’LL DO

Quality Strategy & Judgment Apply risk-based thinking to determine what should be tested, how, and where (unit, integration, domain-level E2E, or QE-owned cross-team E2E). Help define and evolve quality standards and guardrails that scale across teams without becoming burdensome. Identify systemic quality risks and recommend pragmatic improvements in test strategy, architecture, and release practices.

Test Automation & Shared Ownership Build and maintain reliable automated tests across UI, API, and integration layers. Own and maintain QE-managed E2E and regression suites that span multiple product surfaces or represent shared risk. Enable product engineers to write and maintain domain-level tests by providing patterns, helpers, examples, and guidance. Continuously improve test stability, signal quality, and execution speed.

Enablement & Developer Experience Reduce friction for engineers writing tests by improving test utilities, data setup, environment reliability, and local developer workflows. Partner with engineering teams to help them adopt shared testing frameworks and best practices. Act as a consultant and collaborator—helping teams make good quality tradeoffs rather than enforcing rigid rules.

Delivery & Cross-Functional Collaboration Partner early with Product and Engineering during design and refinement to ensure testability is built in from the start. Collaborate closely with Manual QA to align exploratory testing, release validation, and automation coverage. Support predictable delivery by surfacing quality risks early and proposing clear mitigation options.

CI/CD, Release Readiness & Production Learnings Integrate automated tests into CI/CD pipelines with actionable, trustworthy results. Help define release readiness signals, smoke tests, and targeted regression coverage. Use incident data, production issues, and customer feedback to refine test coverage and ownership over time.

Mentorship & Technical Leadership Review automation code and help set quality and maintainability standards. Mentor mid-level and nearshore QEs through pairing, reviews, and informal coaching. Model strong judgment, clear communication, and a pragmatic approach to quality.

WHAT YOU BRING Required Expertise 5+ years in Quality Engineering, Test Automation, or SDET-style roles supporting production software. Strong experience building automated tests for UI and APIs. Proficiency in at least one general-purpose language (TypeScript/JavaScript, Java, C#, Python, etc.). Practical understanding of test strategy and tradeoffs in real-world systems. Experience integrating tests into CI/CD pipelines. Ability to diagnose failures using logs, debugging tools, and system context—not just test output. Clear communicator who can explain quality risks and tradeoffs to both engineers and non-technical partners.

NICE TO HAVE Experience owning or contributing to shared test platforms or libraries. Experience working in legacy or highly coupled systems. Familiarity with observability tools and production validation practices. Experience collaborating closely with manual QA teams. Experience supporting distributed or nearshore teams.

WHY THIS ROLE MATTERS This role ensures quality scales responsibly. By combining direct ownership of high-risk workflows with thoughtful enablement of product teams, Senior QEs help maintain strong quality signals while enabling faster, more confident delivery.
