About the role
Summary
Xtract One Technologies is seeking a Senior Quality Engineer
to lead and enhance quality assurance (QA) efforts across our software, hardware, and machine learning (ML) products. Reporting to the Quality Engineering Manager, you will drive end-to-end QA strategies, from design through deployment, ensuring high standards of performance, reliability, and security. This role involves deep collaboration with cross-functional teams to embed quality into every stage of the product lifecycle.
Key Responsibilities
Quality Assurance Leadership:
- Develop and execute comprehensive QA strategies for software, hardware, and ML components.
- Lead implementation of industry best practices for end to end, performance, security, and compliance based testing.
- Define and maintain quality metrics, test plans, and automated testing frameworks across product layers.
- Perform various testing cycles including automation, regression, performance, and hardware-in-the-loop (HIL).
- Investigate issues through root cause analysis and drive timely resolution of defects from development through field deployment.
- Design, develop, and maintain automated test scripts using code and tools like TestRail, ensuring efficient and comprehensive test coverage.
- Determine appropriate testing methodologies (manual vs. automated) and execute various test types including functional, regression, performance, security, accessibility, end-to-end, sanity, and smoke tests, understanding when each should be performed.
- Lead discussions during design phases to enhance testability and anticipate edge cases, ensuring alignment with 'Definition of Ready' and 'Definition of Done' criteria.
Cross-Functional Collaboration:
- Work closely with software, hardware, ML, DevOps, product management, and customer-facing teams to ensure testability and quality coverage throughout development.
- Partner with external testing labs and regulatory bodies to support compliance efforts (e.g., FCC, CE, EMC).
- Support on-site manufacturing quality audits and monitor supplier adherence to quality standards.
- Collaborate closely with development teams to define clear handoff points for quality activities.
- Actively engage with product management to push for more information and ensure comprehensive requirements are captured as part of 'Definition of Ready'.
Team & Process Development:
- Mentor junior QA engineers and promote a culture of ownership, learning, and high performance.
- Contribute to test process improvement, tool selection, and CI/CD integration.
- Guide discussions during design phases to enhance testability and anticipate edge cases.
- Provide guidance and expertise on all levels of testing, including unit, integration, system, and user acceptance testing.
- Actively mentor Junior Quality Engineers, fostering their growth and technical skills.
Communication & Documentation:
- Communicate quality insights, risks, and timelines effectively to leadership and stakeholders.
- Document QA processes, test methodologies, and compliance requirements for organizational alignment.
Qualifications
Required:
- Bachelor’s degree in Engineering, Computer Science, or a related field (Master’s preferred).
- 5+ years of quality engineering experience across software, hardware, or ML systems.
- Hands-on experience with tools and frameworks such as Cypress, Behave, JUnit, TestRail, Airflow, MATLAB, TensorFlow.
- Proven expertise in implementing automated testing and quality assurance strategies in complex development environments.
- Strong knowledge of root cause analysis, hardware validation techniques (e.g., thermal, signal integrity), and issue troubleshooting.
- Excellent communication and collaboration skills; able to work effectively across technical and non-technical teams.
- Experience with Agile methodologies and tools such as Jira or Asana.
- Willingness to travel up to 20%.
- Demonstrated strong quality engineering experience with hardware, including a deep understanding of networking principles.
- Ability to automate tests proficiently using code and various tools, including TestRail.
- Experience working with cloud environments, specifically AWS.
- Proven ability to mentor and guide Junior Quality Engineers.
- Clear understanding of all levels of testing: unit, integration, system, and user acceptance.
- Strong judgment in determining when to perform manual versus automated tests.
- Comprehensive knowledge of when to perform various types of tests, including functional, regression, performance, security, accessibility, end-to-end, sanity, and smoke tests.
Preferred:
- Background in security, weapons detection, or related industries.
- Experience with ML model validation and deployment pipelines. Demonstrated mentorship or leadership within QA teams
