As an award-winning Sage Tech Partner Plus with over 150 years of combined industry expertise, we develop flagship products like Cim50 and Cim200 to help businesses streamline production, manage stock and maximise operational efficiency.

Role Summary

We are seeking a Software QA Engineer to take ownership of quality assurance across our product suite, with a primary focus on Cim360.cloud, our next-generation multi-tenant cloud manufacturing platform. Cim360 is still in active development (pre-release), so the role will be highly hands‑on, iterative, and embedded closely with the development team.

You will help define and shape how QA is done for Cim360, including tools, processes, and automation, while also supporting testing for our mature desktop products Cim200 and Cim50. These require structured testing on a more predictable schedule and make up a smaller percentage of the role.

This is an opportunity to build modern QA practice within a growing engineering team and ensure reliability across cloud and on‑premise products.

Key Responsibilities

Cim360 (Primary Focus – ~70–80%)

• Develop, maintain, and execute test strategies, test plans, and test cases for a cloud‑native application built on microservices and event‑driven architecture.
• Test and validate:
  • REST APIs and service interactions
  • Data consistency across read/write models
  • Scheduling, MRP logic, stock flows, and manufacturing processes
  • Multi‑tenant behaviour and role‑based access
  • Integrations with QuickBooks Online, Xero, and other external services
• Create and maintain automated UI and API test suites as the product matures.
• Support the development team in identifying, reproducing, and diagnosing issues using logs, telemetry, and distributed tracing.
• Perform regression and release testing across web and API layers.
• Maintain and evolve the QA strategy as Cim360 grows.

Cim200 & Cim50 (Secondary Focus – ~20–30%)

• Plan and Execute functional and regression testing for scheduled releases.
• Validate integrations with Sage 200 and Sage 50.
• Maintain documentation of expected behaviours for mature functionality.
• Ensure stability, backward compatibility, and consistent release quality.

Required Skills & Experience

• 3+ years’ experience in software QA, covering manual and/or automation testing.
• Strong understanding of testing methodologies: exploratory, regression, acceptance, and risk‑based testing.
• Experience testing API‑driven applications, using tools such as Postman, Swagger, or similar.
• Comfortable validating modern web applications (SPA frameworks, component‑based UIs).
• Ability to write clear, structured test cases and defect reports.
• Experience querying data with SQL.
• Excellent communication and collaboration skills.
• Experience working in Agile/Scrum teams.

Desirable Skills

Automation & Tooling

• Experience with UI automation tools such as Playwright, Cypress, or Selenium.
• Experience with API test automation (Postman collections, scripting, or framework‑based).
• Familiarity with CI/CD pipelines, ideally GitHub Actions or Azure DevOps.

Cloud & Architecture Awareness

• Understanding of CQRS (Command Query Responsibility Segregation), particularly how it influences testing patterns around eventual consistency and read/write models.
• Experience with Azure Service Bus or other message‑based systems, helpful for validating asynchronous workflows.
• Exposure to Kubernetes (AKS or equivalent), containerised deployments, and distributed application behaviour.
• Familiarity with Azure Application Insights, including log queries, traces, and performance diagnostics.

Domain Knowledge

• Understanding of manufacturing processes: MRP, BOMs, works orders, stock movements, scheduling.
• Experience with ERP/accounting integrations (QuickBooks, Xero, Sage).
• Familiarity with multi‑tenant SaaS application behaviour.

Technical Familiarity

• Ability to read and understand API specifications, service boundaries, and microservice interactions.
• Basic familiarity with .NET 8+, Entity Framework Core, and REST API design patterns.
• Comfort investigating issues using logs, telemetry, and database queries.

Person Profile

• Is detail‑oriented, analytical, and proactive.
• Takes ownership of product quality without needing constant direction.
• Enjoys problem‑solving and investigating complex system behaviours.
• Can thrive in a fast‑paced environment where requirements evolve.
• Wants to help shape a modern QA practice from the ground up.

What We Offer

• Opportunity to define and grow the QA function for a major new cloud product.
• Influence over tooling, processes, and automation strategy.
• Exposure to a modern SaaS architecture and event‑driven microservices.
• Collaborative development environment with real product impact.
• Competitive salary and benefits (office‑based Southampton or remote UK).
