Job Description
Senior Quality Engineer
Location: Peachtree Corners, GA (Onsite)
Full-Time
About the Role
We are hiring a Senior Quality Engineer to play a critical role in ensuring the reliability, correctness, and resilience of a modern, cloud-based software platform. This role goes far beyond checking boxes or executing scripts — you’ll be embedded within engineering teams, influencing how systems are designed, built, tested, and released.
You’ll take a systems-level view of quality, working across application layers, data pipelines, and infrastructure to surface risk early and prevent failures before they reach production. This is a role for someone who thrives on ownership, autonomy, and impact.
What You’ll Focus OnQuality as a System
- Act as a quality owner across services, APIs, data stores, and user-facing experiences.
- Influence architecture and design decisions by identifying risk patterns early in the development lifecycle.
- Partner with engineers to raise reliability standards rather than reacting after defects appear.
Automation & Engineering
- Build and evolve automated testing approaches that scale with the platform.
- Create and maintain test coverage across multiple layers — from service logic to integration paths.
- Use automation strategically to reduce regressions and increase release confidence.
Data & Platform Validation
- Validate data correctness, consistency, and performance within relational databases.
- Investigate edge cases and failure modes that only appear under real-world conditions.
- Verify cloud-based deployments, environment configurations, and system integrations.
Operational Problem Solving
- Investigate complex production issues alongside engineering teams.
- Perform root-cause analysis and contribute to long-term corrective actions.
- Continuously refine quality practices based on real incidents and system behavior.
What We’re Looking ForCore Qualifications
- 5+ years of experience in a senior or lead-level QA or quality engineering role.
- Strong experience working in cloud-hosted environments.
- Advanced SQL skills with experience validating data integrity and performance.
- Hands-on experience with modern automated testing frameworks (UI and API level).
- Familiarity with CI/CD pipelines and release workflows.
- Deep understanding of Agile delivery and software lifecycle practices.
- Willingness to work fully on-site in Peachtree Corners, GA.
Additional Strengths
- Experience testing large, interconnected systems rather than isolated applications.
- Background in platforms that process high volumes of data or transactions.
- Ability to write small utilities or scripts to support testing and diagnostics.
- Exposure to performance or load testing methodologies.
- Comfort using AI-assisted tools to enhance testing, observability, or automation.
