Software Development Engineer in Test (SDET)

About the role

Built by ex-nation-state operators and AI researchers, Cracken is the world's first Uncensored Vibe Hacking platform that safely amplifies security teams and gives enterprises proven, auditable security resilience. Whom We're Looking For We're looking for a QA to own quality end-to-end across our core cybersecurity products. You'll sit at the intersection of QA engineering, cybersecurity, and AI agent testing - orchestrating test processes, stabilizing release pipelines, and building the test infrastructure that lets us ship stable products to customers faster and more frequently. You'll work closely with sales engineers, cybersecurity researchers, and software engineers throughout the development lifecycle. Beyond writing tests, you'll become a product expert who understands the purpose of every feature, where bugs originate, and how our AI agent architecture should behave under pressure.

Responsibilities

• Core QA Ownership
• Design and own end-to-end integration, smoke, and regression test suites for core product areas
• Create and maintain test scenarios, test cases, and test metrics dashboards
• Schedule automated test suites to run continuously against production and dev environments
• Validate system behavior across functional, integration, and regression testing
• Stability & Release Quality
• Stabilize production and dev environments to enable more frequent, predictable releases
• Contribute to CI/CD pipelines and enforce release quality gates
• Debug test failures, perform root cause analysis, and iterate on coverage gaps
• AI Agent & Cybersecurity Testing
• Understand how our AI agent-based cybersecurity product works and design tests that validate its behavior end-to-end
• Collaborate closely with the cybersecurity team to understand expected product outcomes and edge cases
• Test AI-driven features - not just using AI tools to write tests, but testing the AI agents themselves
• Cross-functional Collaboration
• Work alongside software engineers, sales engineers, and the cybersecurity team throughout development
• Participate in design and code reviews with a quality and maintainability focus
• Evolve into a product knowledge owner - the person who knows how every feature works, what to expect, and where bugs tend to hide
• Must-Have Experience
• 3-5+ years of experience as an SDET or QA Automation Engineer
• Ability to read and write code in at least one language - Python, JavScript/TypeScript, Go
• Experience designing and maintaining automated test frameworks from scratch
• Solid understanding of software development and testing best practices
• Exposure to cybersecurity products or security-adjacent domains; offensive security or red team experience is a strong plus
• Understanding of how AI agents work - you need to know how to test them
• Ability to work independently, take ownership of quality outcomes, and become a product expert

Requirements

• Experience testing AI-driven or LLM-powered products
• Familiarity with CI/CD pipelines and modern DevOps practices
• Experience with distributed or cloud-native systems
• Background in high-reliability or security-sensitive system testing
• Why Cracken?
• Real-world impact
• Our technology is validated in high-stakes, real-world environments and grounded in hands-on internal research.
• Team with a mission
• Ukrainian-heavy international team of PhDs, professors, and senior industry engineers, driven by intrinsic motivation and real-world adversity.
• Adaptive roles
• We shape roles around exceptional talent - your ownership and drive will define your path.
• Perfect timing
• Operating at the intersection of AI, cybersecurity, and autonomous systems, Cracken is uniquely positioned to build resilient security products.
