Senior QA Automation Engineer - AWS & Salesforce (UK)

Project Overview:

At Flosum, we build the leading native DevOps, Release Management, and Data Backup solutions for the Salesforce ecosystem. While our core platform is native to Salesforce, we utilize a hyperscale, open-cloud architecture on AWS for key web applications and high-throughput background processing.

We are looking for an expert

• Senior QA Automation Engineer to design, build, and maintain an end-to-end automated testing framework that bridges our AWS cloud web applications and our core Salesforce architecture.

• What You Will Do:
• Design and implement an automated testing framework covering both our AWS-hosted web app and our connected Salesforce native workflows.
• Automate end-to-end user journeys that cross platforms (e.g., actions initiated in our cloud web UI that trigger deployments or metadata backups inside Salesforce).
• Create stable UI tests for Salesforce Lightning that resist dynamic ID changes and effectively handle Shadow DOM components (using UTAM, Playwright, or enterprise testing tools).
• Develop robust API automation suites to validate real-time data integrations, webhooks, and secure queues running between AWS and Salesforce.
• Integrate the automated test suites cleanly into modern Git-based CI/CD pipelines.
