Job summary

Oteemo, Inc. is seeking a Senior Test Engineer to validate a regulated energy utility's Azure desktop environment against SLA and security controls.

You will design automated tests for boot, logon, and IDE performance, plus synthetic data generation and mock services to keep production isolated. The role demands 7+ years in test/quality engineering, strong automation skills in PowerShell, Python, C#, or TypeScript, and hands-on Azure experience.

Qualifications

• Bachelor's degree or equivalent practical experience.
• 7+ years in test or quality engineering, including 3+ years testing infrastructure, platforms, or cloud environments.
• Automation: strong skills in at least two of PowerShell, Python, C#/.NET, or TypeScript, with tests in CI/CD (Azure DevOps or GitHub Actions).
• Performance & Azure: load testing with k6, JMeter, Locust, or VDI-specific tools; hands-on Azure VMs, networking, monitoring; Docker and docker compose.
• API Testing & Test Data: Postman / Newman, REST, and mock servers; synthetic data generation and masking.

Responsibilities

• SLA & Performance Validation: turn SLA into measurable test plan and thresholds; baseline VDI and score on harness; automate logon, boot, IDE start, concurrent-workload tests.
• Connectivity & Toolchain Validation: run synthetic reachability checks for Git, Copilot, artifact repos, MCP endpoints; write smoke tests for NuGet, npm, pip, Docker.
• Security & State Validation: run negative tests to prove production is unreachable, endpoints denied, SIEM coverage; verify desktop rebuilds clean.
• Test Data, Mocks & Containers: build synthetic data, masked subsets, and mock APIs so tests don't touch production; end-to-end container workflows.
• Infrastructure Gates & Reporting: test IaC/policy with Terratest or Pester; publish SLA scorecards and runbooks.

Job description

Oteemo is an industry-leading technology consulting firm at the forefront of AI-driven, cloud native, enterprise DevSecOps transformation. We build intelligent, automated, secure systems for organizations tackling their toughest technical and business challenges and we're pushing the boundaries of what AI, generative AI, and agentic systems can do in production, not just in theory. Join us and you'll work alongside recognized experts on cutting-edge projects that blend cloud native architecture, extreme automation, and AI/ML at the core. We foster a dynamic, inclusive, and collaborative culture built on continuous learning, where your ideas shape real outcomes for our clients. If you're passionate about building what's next in AI and cloud technology and want to do it with a team that sets the standard rather than follows it, Oteemo is where you belong.

Job Description

We're looking for a Senior Test Engineer to prove that a regulated energy utility's new non-persistent Azure developer desktops meet their SLA and security controls. Every phase ends in an exit gate judged against agreed targets: boot under about 1 minute, IDE cold start under about 15 seconds, source control and Copilot reachable 99% or more, and zero TLS-interception failures. You'll turn those targets into automated, repeatable tests and build the mocks and synthetic data that keep production out of the sandbox.

Key Responsibilities:

SLA & Performance Validation: Turn the SLA into a measurable test plan with pass/fail thresholds and own phase-gate acceptance; baseline the on-premises VDI and score AVD and Horizon on the same harness; automate logon, boot, IDE cold start, and concurrent-workload tests with Login Enterprise or LoadGen.

Connectivity & Toolchain Validation: Run synthetic reachability checks for Git, Copilot, artifact repositories, and MCP endpoints through inspected egress; write NuGet, npm, pip, and Docker smoke tests that catch TLS or endpoint-agent breakage first.

Security & State Validation: Run negative tests proving production is unreachable, public endpoints are denied, App Control and EPM behave as designed, and every action reaches the SIEM; prove desktops rebuild clean while repos, caches, and tooling survive.

Test Data, Mocks & Containers: Build synthetic data generators, masked-subset tooling, and mock APIs (WireMock, Postman, Microcks) so no test touches production; test container and compose workflows end to end.

Infrastructure Gates & Reporting: Test IaC and policy with Terratest or Pester; define the gate AXIOM-built candidate images must pass before Security approves; publish SLA scorecards and hand over the regression suite and runbooks.

Qualifications

Bachelor's degree in a related field (or equivalent practical experience).

7+ years in test or quality engineering, including 3+ years testing infrastructure, platforms, or cloud environments.

Automation: Strong skills in at least two of PowerShell, Python, C# / .NET, or TypeScript, with tests in CI/CD (Azure DevOps or GitHub Actions).

Performance & Azure: Load testing with k6, JMeter, Locust, or VDI-specific tools; hands-on Azure VMs, networking, and monitoring (Azure Monitor, Log Analytics / KQL); Docker and docker compose.

API Testing & Test Data: Postman / Newman, REST, and mock servers; synthetic data generation and masking.

Writes test plans and evidence packages that a security or compliance reviewer accepts.
