Unlock Your Future with Nexaminds!

At Nexaminds, we're on a mission to redefine industries with AI. We're passionate about the limitless potential of artificial intelligence to transform businesses, streamline processes, and drive growth.

Join us on our visionary journey. We're leading the way in AI solutions, and we're committed to innovation, collaboration, and ethical practices. Become a part of our team and shape the future powered by intelligent machines. If you're driven by ambition, success, fun, and learning, Nexaminds is where you belong.

Nexaminds is looking for a Senior Backend QA Engineer with strong API automation expertise and a focus on AI System Validation. In this role, you will be responsible for designing automated test frameworks, analyzing upstream service architectures, and validating non-deterministic systems (such as AI agents and chatbots). The ideal candidate excels at structuring high-quality test plans from complex requirements, utilizing modern automation frameworks, and leveraging AI techniques (like LLM as a Judge and scoring evaluations) to test applications beyond traditional deterministic methods.

Location: CANADA

Qualifications we are looking for:

  • API & Backend Automation: Strong hands-on experience in API test automation using Karate Framework and manual API testing with Postman.
  • AI & Non-Deterministic Testing: Understanding of testing non-deterministic systems, including response scoring techniques, AI agent/chatbot validation, or evaluation concepts like LLM as a Judge.
  • Technical Code Analysis: Ability to read and analyze source code to understand backend architectures, microservices, service dependencies, and upstream impacts.
  • Structured Test Planning: Proven skill in reviewing requirement documents to create concise, precise test plans and automation frameworks without relying on rigid language-specific constraints.
  • Local Environment Setup: Hands-on experience configuring local dev environments for early-stage (shift-left) test execution. 
  • A proactive approach to learning emerging AI technologies and building dynamic testing solutions where standard deterministic QA falls short.
  • Clear, structured, and direct technical communication.

Nice to have:

  • Hands-on experience with the Agent Development Kit (ADK) or MCP applications.
  • Background in contract testing or microservices architecture validation.
  • Prior experience working in complex enterprise environments (e.g., retail or large-scale backend systems).

Job duties:

  • API Testing & Automation: Analyze OpenAPI/Swagger specs to design comprehensive test plans, execute manual testing via Postman, and build robust automated test suites using the Karate Framework.
  • AI System & Agent Validation: Test and evaluate non-deterministic AI outputs, internal AI agents (built with ADK), and MCP applications using evaluation metrics and scoring techniques.
  • Architecture & Upstream Analysis: Inspect source code and upstream services to identify critical dependencies, evaluate technical system impacts, and manage test data across pre-production and production environments.
  • Shift-Left & Local Testing: Configure and launch local development environments to conduct early-stage testing on backend APIs and microservices before deployment.
  • AI-Integrated Test Frameworks: Design scalable test automation strategies that dynamically integrate AI capabilities to validate scenarios standard testing tools cannot handle.

What you can expect from us

Here at Nexaminds, we're not your typical workplace. We're all about creating a friendly and trusting environment where you can thrive. Why does this matter? Well, trust and openness lead to better quality, innovation, commitment to getting the job done, efficiency, and cost-effectiveness.
