Senior Functional Tester

About the Position

We are seeking a dedicated Senior Functional Tester to join our team as a Verification & Validation (V&V) team member. You will own the evidence that platform deliverables work - installing, upgrading, and regression-testing the platform on clean clusters, debugging failed deployments, and helping move validation from manual checks toward repeatable, automated gates.

Responsibilities

• Spin up clean Kubernetes environments, run the platform installer (single-node and HA profiles, interactive and silent modes), and confirm every pod/service is healthy
• Perform installation, upgrade, rollback, regression, and integration testing of the platform and its Helm-packaged components
• Install, debug, and clean up Helm charts; troubleshoot failed deployments using kubectl, logs, and events
• Validate GitOps-driven deployments (Git-versioned configs reconciled through Flux), including upgrade, rollback, and backup/restore flows
• Run config checks and post-install smoke tests; define what "working" looks like for each deliverable
• Create test plans and test cases, log defects, retest fixes, and maintain regression suites for installer/CLI changes
• Contribute to automated post-deployment health checks and pipeline-integrated quality gates
• Produce test evidence suitable for a regulated (medical device / healthcare) environment with formal validation and change control
• Participate in daily stand-ups and sprint ceremonies with a distributed, North America-based scrum team

Requirements

• 3+ years of experience in QA
• Solid background in installation, upgrade, regression, and integration testing
• Hands-on familiarity with Kubernetes and installing Helm charts
• Capability to debug deployments and clean up Helm releases/charts
• Proficiency in functional testing of containerized products, Docker, and Linux shell
• V&V mindset - skills in designing test strategies and producing clear, traceable test evidence
• Clear, concise communication in English (B2); comfortable working asynchronously
• Flexibility to work within US Eastern (ET) business hours

Nice to Have

• Experience with FluxCD and GitOps workflows
• Familiarity with AWS (EC2, ECR, VPC, IAM) and on-prem/virtualized setups (VMware vSphere, Proxmox)
• Knowledge of Terraform, Ansible, and infrastructure testing tools (Terratest, InSpec, or equivalent)
• Competency in test automation/scripting (Bash, Python) and CI (Jenkins)
• Exposure to regulated or compliance-sensitive environments (healthcare, medical devices) and basic Java stack knowledge

We Offer

• International projects with top brands
• Work with global teams of highly skilled, diverse peers
• Healthcare benefits
• Employee financial programs
• Paid time off and sick leave
• Upskilling, reskilling, and certification courses
• Unlimited access to the LinkedIn Learning library and 22,000+ courses
• Global career opportunities
• Volunteer and community involvement opportunities
• EPAM Employee Groups
• Award-winning culture recognized by Glassdoor, Newsweek, and LinkedIn
