Senior Project Manager Lead Validation Tests E2E

Mission Overview

Keystone Solutions is seeking a Senior Project Manager specializing in Lead Validation & E2E Testing for a consultancy mission at a client site. This role involves collaborating closely with existing testing teams and providing methodological and operational expertise across multiple applications, providers, and third-party organizations.

Key Responsibilities

• Review existing testing strategies and plans, assess their coherence, and propose necessary enhancements.
• Identify critical E2E paths involving multiple applications and formalize nominal, alternative, degraded, and recovery scenarios.
• Build and maintain a mapping of stakeholders, applications, interfaces, service contracts, exchanged data, responsibilities, and testing dependencies.
• Define the specific strategy for cross-testing and interoperability, including scope, coverage, sequencing, environments, data sets, entry and exit criteria, and expected evidence.
• Prepare a consolidated campaign plan with existing test coordinators, leveraging their application plans without replacing them.
• Organize campaigns with third-party organizations, ensuring availability of contacts, testing windows, data, and escalation channels.
• Participate directly in the design, preparation, and, when necessary, execution or supervision of the most critical E2E scenarios.
• Verify traceability between business processes, requirements, interfaces, test cases, data, results, anomalies, and execution evidence.
• Coordinate the analysis of cross-anomalies, facilitate the identification of the responsible system or actor, and track corrections and retests until closure.
• Consolidate results produced by various teams and third-party organizations into a single, readable report based on evidence.
• Alert on coverage gaps, unsecured dependencies, and risks that may affect service, revenue, compliance, or users.
• Formulate an independent recommendation, substantiated by results, to advise on a Go or No Go decision for program coordination and decision-making bodies.

Positioning and Interaction with Existing Roles

The Senior Expert ensures the coherence and proof of cross-E2E tests involving multiple domains or third-party organizations. Existing test coordinators remain responsible for detailed strategy, test cases, testers, anomalies, and results within their application or domain. The expert builds on their work, identifies connections between domains, fills in missing scenarios, and organizes the coordinated execution of cross-chains. Providers remain responsible for the quality of their deliveries, internal tests, associated evidence, and correction of anomalies within their scope. Business leaders, Product Owners, and functional experts remain responsible for needs, rules, acceptance criteria, and business validations. Third-party organizations remain responsible for their environments, data, services, and validations within agreed limits. Program managers and sponsors arbitrate priorities and make production decisions based on the consolidated report.

Minimum Experience Required

• At least 10 years of experience in quality assurance, test management, or validation of complex information systems.
• Significant experience in E2E testing and interoperability involving multiple organizations, providers, applications, and technologies.
• Proven experience in a senior advisory and coordination role with established testing teams.
• Ability to design and oversee scenarios covering exchanges and back-office chains.

• Preparation files for E2E testing campaigns.
• Consolidated dashboard of progress, coverage, anomalies, retests, dependencies, and risks.
• E2E and interoperability campaign reports, accompanied by execution evidence.
• Go/No Go or Go under conditions recommendations with residual risks, responsibilities, and compensatory measures.
