Qualys is hiring a Software Engineer in Pune (requisition R0004981), posted on 29 October 2026. The role is full time and sits on the Qualys Sensor Platform, which the company calls its flagship offering, with a focus on the Windows platform. Qualys describes itself as a cloud-based IT, security and compliance provider with over 11,000 active customers in more than 130 countries.
Role Overview
You would work with engineers and architects on prototyping, design, development and support of a highly scalable security platform. This is not a fresher post: it asks for hands-on experience.
Responsibilities
- Analyse, design, code and debug security software for Windows.
- Maintain, support and enhance existing systems and platforms.
- Recommend improvements on a continuing basis.
- Work with other engineers to raise technical standards and apply best practices.
- Work with senior engineers and architects to build features and fix defects.
Requirements
- Bachelor's in computer science or a related field.
- 1 to 3 years as a hands-on engineer building software products.
- 1+ years of C++ programming in a Windows environment.
- Working knowledge of Windows internals: processes, threads, services, registry and the Win32 API.
- Design, prototyping, development, unit testing and performance profiling skills.
- Hands-on with Visual Studio, Git, JIRA and Agile/Scrum.
Desired: ownership of components, exposure to test-driven development, strong quality focus, clear communication and the ability to work with minimal supervision.
What the role involves
This is systems-level work close to the operating system. Day to day you would likely write and debug C++ that runs on Windows machines, read crash data and profile performance. A sensor that collects security data has to be light and reliable, so expect plenty of attention to memory, threads and stability.
Who it suits
It suits engineers with early experience in C++ who enjoy low-level Windows work and want to move into security products. It is a poor fit if your background is web or app development without systems experience.
How to stand out
- Lead with C++ projects that touch Windows APIs: a service, a file monitor, a process tool.
- Know the basics well: process versus thread, how Windows services start, what the registry holds, and how to debug a crash dump. These are likely interview areas given the listed skills.
- Show any profiling work, such as how you found and fixed a slow function.
- Mention familiarity with security concepts if you have it, though the posting does not list it as required.
Check before you apply
- The posting does not list pay.
- No closing date appears on the page.
- The experience band is 1 to 3 years, so very new graduates may not qualify.
- Check whether the role is on site or hybrid, since the posting only names Pune.
