Senior QA Engineer / QA Team Lead (Cybersecurity · On-prem Appliance)

We are developing a cutting-edge cybersecurity product delivered as an on-prem appliance. Our solution includes back-end services (Python & Golang), a modern React interface, multiple data stores (PostgreSQL, Elasticsearch, MongoDB), and infrastructure components for running honeypots in containers.

We are looking for an experienced Senior QA Engineer / QA Team Lead who will take ownership of building our entire QA function from the ground up — processes, tooling, automation strategy, roadmap, and the future QA team.

If you want to have a real impact, define how quality is done, and work with a highly technical cybersecurity product — this role is for you.

Responsibilities

===============================

1. QA Strategy & Process Ownership

• Build the QA function from zero: processes, standards, workflows, quality gates, documentation.
• Define the testing strategy for backend services, frontend, APIs, data pipelines, and infrastructure.
• Establish CI/CD testing stages, automation coverage, and release quality criteria
• Set up test management, defect tracking, traceability, and reporting processes.

2. Hands-on QA Execution

• Perform manual testing of backend components, APIs, web UI, and appliance-level functionality.
• Conduct functional, regression, integration, system, performance, and stability testing.
• Validate complex multi-service interactions (Python, Go microservices, containers).
• Test deployment/upgrade flows of on-prem appliances.

3. Automation & Tools Development

• Design and build automation frameworks (preferably Python + pytest/Playwright)
• Introduce automated API tests, integration tests, sanity/regression suites.
• Contribute to infrastructure-level testing (containerized honeypots, networking behaviour, OS-level logic).

4. Cross-Team Collaboration

• Work closely with engineering (backend, frontend, devops) to ensure testability and product quality.
• Participate in architecture discussions and proactively identify quality risks.
• Collaborate with product management to refine requirements and acceptance criteria.

5. Leadership & Growth

• Optionally hire, mentor, and lead a QA team as the company grows
• Drive continuous improvement and foster a quality-first culture.
