Senior Manual Test Engineer information

What does a senior manual test engineer do?

A Senior Manual Test Engineer is responsible for designing, executing, and maintaining test cases to ensure the quality of software applications. They collaborate with development teams to identify issues, report bugs, and verify fixes without relying on automated tools. Their seniority implies greater responsibility in mentoring junior testers, creating comprehensive test plans, and sometimes coordinating testing efforts across multiple projects. They also contribute to overall quality assurance processes and help improve testing strategies based on their experience.

What are the key skills and qualifications needed to thrive as a senior manual test engineer?

To excel as a Senior Manual Test Engineer, you need strong analytical skills, a deep understanding of software testing methodologies, and experience with test planning and execution, typically supported by a degree in computer science or a related field. Familiarity with bug tracking systems like Jira, test management tools such as TestRail, and relevant certifications like ISTQB are commonly expected. Exceptional attention to detail, problem-solving abilities, and effective communication are vital soft skills for collaborating with development teams and ensuring quality deliverables. These abilities are crucial for consistently identifying defects, improving product quality, and driving efficient testing processes.

How does a senior manual test engineer typically collaborate with developers and other QA team members during the software development lifecycle?

As a Senior Manual Test Engineer, collaboration with developers and other QA professionals is integral throughout the software development lifecycle. You will participate in requirement reviews, design test plans, and provide feedback during sprint planning. Regular communication with developers helps clarify intended functionality and resolve defects efficiently, while mentoring junior testers and coordinating with automation engineers ensures comprehensive coverage. This cross-functional teamwork fosters a shared responsibility for software quality and accelerates issue resolution.

What is the difference between Senior Manual Test Engineer vs Manual Test Engineer?

AspectSenior Manual Test EngineerManual Test Engineer
CertificationsISTQB, CSTE, or equivalentISTQB or similar certifications often preferred
Work EnvironmentLed testing teams, involved in test planning and strategyExecute test cases, report bugs, and verify fixes
ResponsibilitiesDesign test plans, mentor junior testers, analyze complex issuesPerform manual testing, document defects, ensure test coverage

The main difference between a Senior Manual Test Engineer and a Manual Test Engineer lies in experience, responsibilities, and leadership. Senior testers typically lead testing efforts, mentor team members, and handle complex scenarios, while manual testers focus on executing test cases and reporting issues. Both roles require similar certifications and work in comparable environments, but the senior role involves more strategic and leadership duties.

Austin, TX

Full-time

Posted 20 days ago


Job description

About the Opportunity
Seekr builds trust into every stage of the AI lifecycle - providing a complete platform to build, train, validate, securely deploy, and monitor transparent generative AI applications and agents. We're hiring a Senior Manual QA Engineer to partner with our Manual QA Lead and raise the quality bar across Seekr's entire product suite.
You will be a force multiplier in mentoring junior engineers, championing AI-augmented QA workflows including Claude AI and MCP integrations, and driving quality outcomes with minimal direction. You'll work directly with modern agentic tooling from day one and be expected to lead its adoption within the QA practice.
Key Responsibilities
  • Test strategy & execution: Design and execute functional test cases, suites, and plans for UI and API surfaces in TestRail (incl. MCP + Claude AI integration); lead test plan reviews and peer approvals for junior engineers
  • AI tooling & MCP integration: Use Claude AI and MCP server integrations daily for test case generation, defect analysis, and knowledge base contributions; evaluate and validate AI-generated and agentic workflow outputs
  • Regression & release ownership: Co-own regression strategy and end-to-end release validation cycles with the Manual QA Lead; drive release readiness tracking and milestone reporting
  • API & technical testing: Perform advanced manual API testing; build and maintain Postman collections; apply boundary analysis, equivalence partitioning, exploratory testing, and risk-based coverage
  • Defect management & comms: Triage and log defects in JIRA with executive-ready clarity; proactively flag risks with context and recommended actions via Slack and email
  • Requirements analysis: Analyze requirements for ambiguity and testability; contribute to SDLC and systems integration process improvements across the engineering org
Skills and Qualifications
  • 5+ years as a Software QA / Test Engineer with a strong, demonstrable focus on manual testing
  • Expert-level proficiency designing and executing test cases, suites, and plans for UI and API layers
  • Deep familiarity with TestRail (or equivalent TCM) and Postman; prior TestRail MCP server integration exposure is a strong plus
  • Strong QA foundations: equivalence partitioning, boundary value analysis, exploratory testing, risk-based testing, root cause analysis
  • Proven experience mentoring or coaching junior QA engineers - formally or informally
  • Demonstrated ability to set standards, model best practices, and elevate team output through direct example
  • Hands-on experience with Claude AI (claude.ai or API) as a productivity tool in a QA or software development context
  • Working knowledge of MCP (Model Context Protocol) integrations - connecting QA tooling (TestRail, JIRA) with AI assistants
  • Comfort operating in AI-augmented workflows where outputs are non-deterministic, probabilistic, or agent-driven
  • Strong SDLC knowledge - Agile and Waterfall environments
  • Must reside near Austin, TX or Reston, VA and be available 3 days/week in office
Bonus Points
  • Experience testing AI/ML systems, LLM-powered products, or generative AI platforms - especially non-deterministic or agentic outputs
  • Familiarity with Claude Code, agentic AI orchestration frameworks, or next-gen developer tooling
  • Experience testing SDK-based tools or consuming APIs in code
  • Elementary Python scripting - reading/writing basic test scripts or automation helpers
  • Prior formal or informal QA lead or senior contributor experience with ownership of team standards or onboarding
  • Bachelor's degree in Computer Science or equivalent practical experience
