ROLE PURPOSE The Senior Software Test Engineer leads the quality engineering strategy across complex, multi-platform systems encompassing middleware (REST API/) and Web UI. This role owns the test automation architecture, drives quality processes, and provides technical leadership to the QA team. The Senior engineer operates as a quality champion across the engineering organization — influencing delivery teams on testability, shifting quality left, and ensuring robust coverage across the full software stack. KEY RESPONSIBILITIES

Test Strategy & Architecture ▸

Define and own the overarching test strategy covering functional, integration, regression and performance, testing.▸

Architect, build, and govern scalable test automation frameworks for API (RestAssured/Java) and Web UI (Selenium)▸

Establish standards, patterns, and guidelines for test code quality, maintainability, and reusability.▸

Drive the test automation roadmap, aligning it with product delivery goals and technology evolution.▸

Design end-to-end testing strategies for functional workflows including automation.▸

Define AI/GenAI testing strategies — including model validation, prompt engineering testing, bias detection, and quality metrics for LLM-based applications. Technical Leadership & Delivery ▸

Lead the technical implementation of complex test scenarios across middleware and UI.▸

Drive CI/CD integration, ensuring automated test execution is embedded throughout the delivery pipeline.▸

Perform deep-dive root cause analysis on complex system failures and intermittent test issues.▸

Champion test environment management strategies — infrastructure-as-code and containerization for consistent environments.▸

Define and automate test data management strategies for multi-environment, data-sensitive systems.▸

Lead AI-powered testing initiatives — leveraging GenAI tools for test case generation, and intelligent test optimization. Quality Process & Governance ▸

Define QA entry/exit criteria, testing policies, and quality gates across the SDLC.▸

Own quality metrics and dashboards — coverage, defect trends, automation ROI, and release readiness reporting.▸

Drive shift-left quality initiatives — embedding test thinking in requirements, architecture, and design phases.▸

Conduct risk-based test planning and communicate quality risk to stakeholders with clarity and evidence.▸

Lead test reviews, retrospectives, and continuous improvement of QA processes.▸

Establish governance frameworks for AI/ML testing — including model versioning, explainability testing, and compliance validation for AI-driven features. People & Collaboration ▸

Mentor, coach, and develop Junior and Mid-level Test Engineers in both technical and professional skills.▸

Act as a quality ambassador, fostering a quality culture within Agile delivery teams.▸

Collaborate with architects and developers to ensure system designs are testable and observable.▸

Represent the QA function in cross-team and stakeholder forums — providing quality assessments and release recommendations.▸

Champion AI literacy within the QA team — upskilling engineers on AI testing methodologies, GenAI tools, and emerging AI quality practices. REQUIRED SKILLS & QUALIFICATIONS ▸

Bachelor's degree in Computer Science, Software Engineering, or equivalent (or demonstrable equivalent experience).▸

8+ years of software testing experience, with at least 3 years in a senior or technical lead capacity.▸

Expert-level Java programming — design patterns (Factory, Strategy, Builder), multi-threading awareness, and clean code principles.▸

Deep expertise in Rest Assured — advanced request chaining, dynamic extraction, schema validation, and data-driven strategies.▸

Advanced Selenium WebDriver skills — grid management, parallel execution, custom reporting, and complex DOM interactions.▸

Deep CI/CD expertise — pipeline design, parallelization of test stages, test result publication, and failure triage automation.▸

Solid knowledge of distributed systems and microservices architecture, including experience with AWS.▸

AI/GenAI Testing Expertise — Hands-on experience testing AI/ML models, GenAI applications, and LLM-based systems; understanding of model validation, bias detection, prompt engineering testing, and AI-specific quality metrics.▸

AI/GenAI Testing Expertise — Hands-on experience on Co-Pilot and similar tools. PREFERRED / NICE-TO-HAVE ▸

ISTQB Advanced Level Certification — Test Manager or Test Automation Engineer certification.▸

API and Contract Testing — Experience with tools such as Pact, Postman, JMeter, and Gatling.▸

Observability Practices — Familiarity with log analysis and distributed tracing (Dynatrace) in a testing context.▸

Regulated Industry Experience — Preferably in Airlines/ Retail domains.▸
