## About the Role

* Software Testing Fundamentals: strong commercial experience in software quality assurance, covering functional and system integration testing (SIT).

 * Supply Chain Domain Knowledge: Hands-on experience testing supply chain, logistics, e-commerce fulfilment, retail operations, or ERP/WMS/OMS platforms.
 * AWS Cloud Experience: Practical working knowledge of AWS services (such as EC2, S3, Lambda, SQS/SNS, RDS, DynamoDB, and CloudWatch) for checking logs, inspecting queues, and validating cloud deployments.
 * API & Integration Testing: Strong experience testing APIs and data integrations using tools such as Postman, SoapUI, or RestAssured, along with solid SQL skills for backend data validation.
 * CI/CD & Agile: Familiarity with Agile/Scrum workflows, version control (Git), and running automated tests within CI/CD pipelines (e.g., GitHub Actions, Jenkins, or GitLab CI).

 * Analytical Aptitude & Problem-Solving: Strong analytical and logical reasoning skills, with the ability to understand complex requirements, investigate issues, challenge assumptions, and identify gaps in test coverage.
 * Attention to Detail & Quality Focus: A thorough, inquisitive approach to testing, exploring business rules, data flows, dependencies, edge cases, and negative scenarios to improve test coverage and identify defects that could otherwise be missed. Maintain accurate test evidence and clear defect reports to support reliable, high-quality releases.
 * Communication & Collaboration: Clear written and verbal communication skills, with the ability to ask relevant questions, explain defects and risks, and work constructively with technical and business stakeholders to resolve issues.

Desirable Skills:

 * Experience testing EDI (Electronic Data Interchange) formats (such as EDIFACT or X12) and third-party carrier/WMS APIs.
 * Exposure to performance testing tools (such as JMeter or k6) to validate system behaviour during peak seasonal volumes (e.g., Black Friday).
 * ISTQB Foundation certification or equivalent testing qualification.

## Description

We are looking for a detail-oriented Software Test Engineer to ensure the quality, accuracy, and reliability of our cloud-based supply chain platforms. Operating within an AWS environment, you will validate complex end-to-end workflows across inventory, warehousing, order fulfilment, and logistics.

You will work closely with developers, and operations teams to ensure our systems handle real-world supply chain data and integrations seamlessly., * End-to-End Supply Chain Testing: Design and execute functional, integration, and regression test cases covering core supply chain flows such as order management (OMS), warehouse operations (WMS), inventory tracking, and carrier integrations.

 * Cloud & API Validation: Test microservices, RESTful APIs, and event-driven data pipelines hosted on AWS to ensure reliable data flow between internal systems and external third-party logistics (3PL) partners.

 * Data & Integration Verification: Validate database updates and perform Enterprise Data Warehouse (EDW) testing, including extract, transform and load (ETL) processes, source-to-target data reconciliation, and validation of data completeness, accuracy, transformation rules and reporting outputs.

 * Agile Collaboration: Participate in sprint planning, backlog refinement, and release sign-offs, bringing supply chain domain insight to catch edge cases early in development.
