Job description

Come Forge the Future of Machine Identity Security for Operational Systems

Where: Tysons, VA (Hybrid)

Reporting to: Sr. Director of Engineering

About Corsha:

At Corsha we're not just selling software; we're fundamentally reshaping how the most critical industrial and operational technology (OT) systems are secured. We're a cybersecurity startup in the DC area, driven by a mission to bring trust, resilience, and identity to the operational systems that power our world – from factories to power grids. We're building the future of machine identity security, and we need a tenacious quality engineer to join our front lines.

Tired of the Status Quo? Ready to Secure the Unseen? Here’s your Opportunity:

If you're an engineer who takes personal stake in improving product quality, thrives in a fast-paced environment, and has a passion for building robust testing frameworks, then read on. We move fast, we build for impact, and we need a strategic, data-driven thinker to help us ensure our solutions are reliable and production-ready for the machines that matter most.

Your Mission:

As a Senior Quality Engineer on our Quality team, your mission is to architect, scale, and maintain automated testing frameworks for our Machine Identity Platform (mIDP). You will serve as a quality champion-defining test strategies, eliminating automation friction, and empowering engineering teams to ship resilient OT security solutions with high confidence.

What You'll Do:

• Automation Strategy & Execution: Define, implement, and execute testing strategies for platform releases, covering backend services, proxy traffic, identity gatekeepers, frontend UIs, containerized deployments, and network configurations.
• Framework Code Ownership: Become a core code owner for both backend and frontend test automation repositories, taking personal stake in continuous refactoring, code reviews, and framework scaling.
• Pipeline & Tooling Integration: Build seamless integrations between automated test suites, test case management tools, continuous integration pipelines, and internal engineering tools to minimize feedback loops.
• Leverage AI for Quality: Research and evaluate AI/LLM-assisted developer tools to accelerate testing workflows, focusing on automated test case generation, prompt engineering for edge-case coverage, and optimizing framework code maintenance.
• Failure Diagnostics & Debugging Data: Automate test suites so that when a test fails, it automatically captures all relevant container logs, proxy traffic traces, and system error logs needed for developers to immediately reproduce and fix the bug.
• Security & Network Traffic Verification: Execute backend commands and inspect real-time network traffic to validate identity gatekeepers, access control proxies, and mTLS access policies.
• Defect Triage & Stabilization: Investigate failing test runs, diagnose root causes, write necessary code fixes for automated tests, and systematically eliminate flaky tests to ensure reliable gating.
• Meticulous Test Case Design: Partner with developers and functional leads upfront to translate complex platform features into comprehensive test cases within enterprise test management systems.

What we need you to bring:

• Education: Bachelor's degree in Computer Science, Engineering, or a related technical field, or equivalent practical experience.
• Proven Technical QA Experience: 5+ years of hands-on experience architecting test automation frameworks and validating complex backend, proxy, and security infrastructure environments.
• Test Strategy Expertise: Demonstrable ability to design detailed test plans for new platform capabilities that anticipate complex system failure modes.
• Framework Mastery: Practical experience architecting backend and system automation suites in Python, Go, or TypeScript using major testing frameworks (e.g., PyTest or similar system-level test tools).
• Infrastructure & CI/CD Proficiency: Solid foundation in modern CI/CD automation (e.g., GitHub Actions, Jenkins) and container orchestration (Docker, Kubernetes) to embed automation directly into deployment workflows.
• CLI & System Diagnostics: High comfort operating in command-line environments, diagnosing platform components, and inspecting network-level proxies or gatekeepers.
• Identity & Security Protocols: Deep understanding of identity authentication and security mechanisms (mTLS, PKI certificates, JWTs) with the diagnostic skills to troubleshoot connectivity and security policies.
• OT & Industrial System Awareness: Understanding of operational technology (OT) environments, hardware testbeds, and the unique security/connectivity constraints of testing industrial systems.
• Enterprise QA Tooling: Experience using enterprise test case management (TCM) tools and Agile defect tracking workflows to ensure full test coverage traceability.
• Technical Communication: Exceptional communication skills with a track record of authoring clear documentation, bug analyses, and framework guidelines.

Bonus Points For:

• Practical experience with advanced testing concepts beyond functional automation, such as Performance, Load/Stress, Chaos, or Fuzz testing for backend infrastructure.
• Familiarity with Helm charts and contributing to test utilities in Go.
• Practical experience executing test suites across both cloud-hosted infrastructure and on-premises deployment models.
• Hands‑on experience testing on real hardware, bare metal, or distributed ICSp testbeds and digital twins designed to replicate physical industrial environments.
• Experience designing test strategies for non-deterministic systems or AI/ML pipelines, utilizing evaluation frameworks (evals), benchmark testing, and statistical validation to assess model output quality and reliability.

Why Forge your Path with Corsha?

• Real-World Impact: Your work won't just sit on a server; it will actively defend the critical operational systems that underpin our society. This is an opportunity to make a tangible, immediate difference.
• Bleeding Edge: Be at the forefront of securing the intersection of cybersecurity, machine identity, and OT. We're defining the future, not just following trends.
• Growth & Ownership: Working at a startup, your contributions will directly shape our product, our culture, and our success. You'll work with incredible people that care and have impact.
• Culture of Innovation: Join a team of brilliant, passionate engineers dedicated to solving the hardest problems. We foster a collaborative, intellectually stimulating, and supportive environment.
