We are looking for a skilled Functional Tester to join the team as a Verification & Validation (V&V;) team member. You will help confirm that platform deliverables work — installing, upgrading, and regression-testing the platform on clean clusters, debugging failed deployments, and supporting the team's effort to 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; help define what "working" looks like for each deliverable
- Create test cases, log defects, retest fixes, and maintain regression suites for installer/CLI changes
- Support the development of 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

- 2 years of experience in QA
- Experience with installation, upgrade, regression, and integration testing
- Hands-on familiarity with Kubernetes and installing Helm charts




- Ability to debug deployments and clean up Helm releases/charts
- Experience in functional testing of containerized products, Docker, and Linux shell
- V&V; mindset — understanding of test design principles and ability to produce clear, traceable test evidence
- English proficiency at B1 level or above
- Flexibility to work within US Eastern (ET) business hours

Nice to have

- Exposure to FluxCD and GitOps workflows
- Familiarity with AWS (EC2, ECR, VPC, IAM) and on-prem/virtualized setups (VMware vSphere, Proxmox)
- Basic knowledge of Terraform, Ansible, and infrastructure testing tools (Terratest, InSpec, or equivalent)
- Basic test automation/scripting skills (Bash, Python) and experience with 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 integral 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
