Test Engineer

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.

Key Responsibilities:

• 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.

Required Skills & Experience:

• 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.
• 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.
• ISTQB Foundation certification or equivalent testing qualification.
