Role Specification

Role Description

We are looking for a Test Lead to define and drive the end-to-end QA strategy for our AI-powered platform. This role involves testing components across the stack—including ML models/backend, backend services, and frontend interfaces—to ensure accuracy, performance, security, and reliability. You will lead a team of testers, collaborate cross-functionally, and build automation pipelines aligned with CI/CD practices.

Role Title

SW QA Engineer/Tester

Role Purpose

What the role entails

(Key Responsibilities)

Test Strategy & Planning

Define and own the comprehensive test plan for ML inference, backend workflows, and frontend user experience.
Identify test scenarios for real-time sensor data pipelines, anomaly/event detection, historical playback, and UI s/configs.
Design test cases with focus on modularity, reusability, and traceability to requirements.
Define and track test coverage, maintain regression test suites, and handle test data design.

ML Model Testing

Validate ML outputs (event classification, anomaly scores) against labeled test datasets.
Perform accuracy testing, A/B comparison, drift detection, and model regression checks.
Test model integration in real-time pipelines (latency, fault tolerance, failover behavior).

Backend & API Testing

Validate backend APIs that consume ML outputs, transform data, and expose events to the UI.
Test REST/gRPC endpoints, data transformations, streaming services (Kafka), and storage layers (PostgreSQL, Redis).
Design load, concurrency, and recovery tests for backend services.

Frontend Testing

Verify UI correctness for event visualization, timeline navigation, and control tools.
Automate UI workflows using tools like Cypress, Playwright, or Selenium.
Ensure responsiveness, accessibility, and data consistency in real-time dashboards.

Automation & DevOps Alignment

Lead setup of test automation pipelines integrated with CI/CD (GitHub Actions, GitLab CI, etc.).
Own the implementation of smoke, sanity, regression, and performance suites.
Collaborate with DevOps for observability in test environments, test parallelization, and reporting.

Leadership & Collaboration

Mentor QA engineers and drive best testing practices across the platform.
Collaborate with ML, backend, frontend, and product teams to review requirements and raise quality gates.
Drive root cause analysis and support release readiness with QA sign-off.

What we are looking for in you

(Skills, Knowledge, Special Attributes, Mobility)

4 years in software testing with at least 1 years in a lead role.
Experience testing ML model pipelines, data-driven APIs, and real-time UI platforms.
Strong command over test design techniques, risk-based testing, and shift-left testing practices.
Proficient in Python or JavaScript for writing automation scripts.
Hands-on with tools such as Postman, JMeter, Pytest, Cypress, or Playwright.
Familiarity with Kafka, REST/gRPC, Docker, and Linux environments.
Knowledge of CI/CD, test versioning, and defect lifecycle management tools (e.g., JIRA, TestRail).
Experience with model explainability testing (SHAP, LIME) or model monitoring tools.
Exposure to edge device testing, cloud deployments (GCP), and real-time event handling systems.
Knowledge of performance engineering and security testing basics.
