Candidate profile
As a Technical Test Lead at CGI, you'll take responsibility for planning, coordinating and delivering functional and integration testing across complex, interconnected systems. You'll provide technical leadership to test analysts and engineers, ensuring that applications, APIs, messaging services and end to end business processes operate as expected.
Working with modern technologies including Salesforce, MuleSoft and AWS, you'll collaborate with architects, developers, business analysts and delivery teams to embed quality throughout the development lifecycle. This is an opportunity to take ownership of technically challenging testing activities, influence quality engineering practices and contribute to the successful delivery of high profile transformation programmes.
You'll work closely with the Test Manager, solution architects, developers and business stakeholders to translate technical designs and business requirements into effective test coverage. With a particular focus on Salesforce applications, MuleSoft integrations and cloud hosted services, you'll ensure that testing is risk driven, technically robust and aligned with programme delivery milestones.
• Lead & Deliver: Plan, coordinate and oversee functional, system and integration testing activities, ensuring comprehensive coverage of business processes, technical interfaces and end to end user journeys.
• Drive Technical Testing: Lead validation of Salesforce applications, MuleSoft APIs, messaging services and integrations, including data transformation, routing, error handling, retry mechanisms and message processing.
• Design & Execute: Define test scenarios, review test cases and oversee execution across application workflows, REST/SOAP APIs, XML/JSON interfaces, databases and integrated systems.
• Collaborate & Integrate: Work closely with developers, architects, business analysts and delivery teams to understand solution designs, identify integration risks and resolve technical testing challenges.
• Champion Quality & Automation: Identify opportunities to improve regression coverage, introduce automation and embed effective testing practices within Agile and DevOps delivery processes.
• Manage Defects & Risks: Lead technical defect investigation, triage and resolution, ensuring issues are clearly documented, prioritised and retested, with risks communicated to the Test Manager.
• Support UAT & Release Readiness: Coordinate technical support for User Acceptance Testing, ensuring test environments, integration services, test data and supporting evidence are ready for business validation.
• Mentor & Empower: Provide day to day technical guidance to test analysts and engineers, reviewing test deliverables, sharing expertise and promoting consistent quality engineering standards.
• Measure & Report: Monitor test progress, coverage, defects and quality indicators, providing clear technical reporting and evidence to support test completion and release readiness decisions.
Required qualifications to be successful in this role
You'll bring a strong background in technical testing, with proven experience leading functional and integration testing across complex enterprise environments. You'll combine hands on technical knowledge with the ability to coordinate testing activities, troubleshoot integration challenges and support teams in delivering high quality solutions.
You'll be comfortable working across multiple technologies and collaborating with stakeholders at different levels, with a proactive approach to identifying risks, improving test coverage and driving successful outcomes.
• Proven experience as a Technical Test Lead, Integration Test Lead or Senior Test Engineer on complex digital transformation programmes.
• Strong experience planning, designing and leading functional, system integration and end to end testing activities.
• Practical experience testing Salesforce applications, including Lightning or Experience Cloud, business workflows, role based access controls and application configuration.
• Strong understanding of MuleSoft or comparable enterprise integration platforms, including API testing, message processing, transformation, routing and error handling.
• Experience testing REST/SOAP APIs, XML/XSD, JSON and message driven architectures, including asynchronous processing, queues and retry/replay mechanisms.
• Proficiency with API testing tools such as Postman, SoapUI or equivalent, alongside test management and defect tracking tools such as Jira, Azure DevOps or similar.
• Experience validating data integrity, database interactions and integration behaviour using SQL and other technical testing approaches.
• Good understanding of test automation principles, regression testing and the integration of automated testing into CI/CD pipelines.
• Familiarity with cloud hosted environments, particularly AWS and the testing considerations associated with distributed enterprise applications.
• Strong analytical and troubleshooting skills, with the ability to investigate complex technical defects across interconnected systems.
• Experience coordinating test analysts, reviewing test deliverables and providing technical guidance to testing teams.
• Excellent communication and stakeholder management skills, with experience working alongside developers, architects, business teams and test management.
• Understanding of Agile delivery methodologies, software development lifecycles and risk based testing practices.
Desirable qualifications and experience
• ISTQB Foundation or Advanced Level certification, particularly Technical Test Analyst or Test Management.
• Experience testing solutions within UK public sector, justice, government, or other regulated environments.
• Experience supporting Authority led UAT, operational acceptance testing and production readiness activities.
• Familiarity with Salesforce and MuleSoft integration architectures in secure, high availability environments.
• Experience with test automation frameworks and scripting languages such as Java, Python or JavaScript.
• Understanding of performance, security and resilience testing, including their dependencies on functional and integration testing.
