Job description

Insomniac Design is a global digital agency headquartered in Washington D.C., with offices in London, Bucharest and Chisinau. We’re an agile, determined and innovative team organized by functional areas of expertise — Creative, Technology, Strategy, and Management. We specialize in human-centered design with deep focus on design thinking and digital transformation.

We are seeking an experienced Mid-Level QA/Software Tester to join our team. As a Mid-Level QA/Software Tester, you will independently own end-to-end quality assurance — from test planning and requirements analysis through automated test development, performance testing, defect management, and knowledge transfer. This role requires a self-directed professional who can operate autonomously, communicate effectively with both technical and non-technical stakeholders, and deliver comprehensive testing across functional, integration, performance, accessibility, regression, and user acceptance testing.

This is a hybrid position based in Washington, D.C. with on-site presence as required.

General Responsibilities

• Own the full QA lifecycle for assigned work packages — test planning, test design, test execution, defect management, and test reporting

• Operate with minimal supervision, taking ownership of quality outcomes and proactively identifying risks

• Follow the organization’s AI-Driven QA workflow, including use of internal tools for accelerated test specification generation, with mandatory human review and approval at every stage

• Collaborate with project teams, client stakeholders, and third-party vendor development teams

• Communicate testing progress, defect trends, and risk areas through weekly status reports

• Follow SDLC processes and contribute to continuous process improvement

• Participate in project meetings including sprint reviews, defect triage, planning sessions, and Operational Readiness Reviews

Technical Responsibilities

• Develop and maintain comprehensive test plans, test cases, test scenarios, and test scripts based on project requirements, acceptance criteria, and system specifications

• Build and maintain Requirements Traceability Matrices (RTMs) to ensure full test coverage

• Execute manual and automated tests across functional, integration, regression, performance, accessibility, and user acceptance testing

• Develop automated test scripts

• Develop performance and load testing scripts

• Write and execute SQL Server queries for data validation and data migration verification

• Perform cross-browser testing across Chrome, Firefox, Safari, and Internet Explorer

• Develop user guides and knowledge transfer documentation for end users and client technical staff

• Support the implementation and maintenance of automated testing tools and regression suites

• Capture transaction response time metrics during automated functional testing

• Validate legacy data migration — verifying data integrity, referential integrity, and correct application behavior for migrated records

• Validate system availability and data integrity following disaster recovery failover events
