AI-First. Future-Driven. Human-Centered.
At OpenText, AI is at the heart of everything we do—powering innovation, transforming work, and empowering digital knowledge workers. We're hiring talent AI can't replace to help us shape the future of information management. Join us.

As a global leader in secure information management, OpenText empowers businesses to stay ahead of the ever-evolving cyber threats. OurCybersecurity Enterpriseportfolio is formidable, offering innovative solutions that safeguard organizations from malicious attacks, data breaches, and cyber vulnerabilities. By joining our team, you'll be at the forefront of developing and implementing state-of-the-art security technologies, protecting critical assets and sensitive information for clients worldwide.

Your Impact:

We’re looking for a creative, self-directed C++ developer who is fascinated by the inner workings of browsers and is eager to become an expert. This role isn’t for someone who just wants to complete assigned tasks — it’s for someone who wants to figure things out, explore, and evolve into a key technical authority on browser behavior and internals.

You’ll be modifying the actual source code of a browser— not writing web pages but altering how the browser itself behaves. You'll investigate how JavaScript is interpreted, how the browser handles network traffic, and inject visibility and instrumentation into those systems. Why? So that security researchers and penetration testers can use the tool you’ve helped build to detect web vulnerabilities that otherwise go unnoticed.

We don’t expect you to know everything on day one — but we do expect you to be sharp in C++, curious by nature, and motivated to learn how modern browsers work under the hood. If you've ever dreamed of writing your own compiler, digging through browser source trees, or tracking every HTTP request from origin to execution context — this is the role for you.

What the role offers:

As a Lead Software Developer, you will:

• Work on industry-leading cybersecurity testing platform.
• Solve complex tasks to meet business needs.
• Learn about the latest security breaches across various tools, technologies, and programming languages.
• Modify the actual source code of a browser— not writing web pages but altering how the browser itself behaves.
• Design and implement the next generation Dynamic Application Security Testing (DAST) scanner.
• Engage in full-stack development including data, engine, and user interface layers.
• Implement security analytics to gain comprehensive web security knowledge from top to bottom.

What you need to Succeed:

• Excellent programming skills in C++, JavaScript, TypeScript.
• Excellent knowledge in networking and how the networking in browser works, NodeJS vs browser.
• Ability to use a debugger on live browser in production to diagnose issues.
• Excellent diagnostics and code reading skills.
• In depth understanding of the JavaScript engine (from parsing to event loop and callback queue, microtasks, inline caching etc.)
• Excellent knowledge of browser inner network traffic handling and how threads are dispatching network requests.
• In depth understanding of browser extensions inner workings is a must – what is an extension, what is extension manifest V3, relationship between the page and different part of the extension, ability to modify the browser to disable the restrictions on extensions.
• Ability to diagnose and fix issues on internal browser/ operating systems like “On mac only some JavaScript events are not raised when the SSL/TLS version of the site is used”.
