Software Engineer

Qualys builds cloud security and compliance products, and this role sits with the engineering teams that write native code for its agents and platform services. The posting asks for C/C++ development on enterprise or consumer products running on Linux or macOS. Because the experience window starts at zero, recent graduates and early-career developers can both apply.

What you'll do

• Write and maintain C/C++ code for product lines that run on Linux and macOS
• Track down and fix defects using debuggers, logs and careful reasoning
• Use data structures, algorithms and system design to build fast, scalable components
• Follow team practices including coding standards, code reviews, source control and CI/CD pipelines
• Test your own changes and help keep release quality high
• Explain technical choices to peers and help the team agree on an approach

What they ask for

• BE/BTech or ME/MTech in Computer Science Engineering, or MCA
• 0 to 4 years of experience as a software engineer, developer or similar role
• Core skill in C/C++ development on Linux or macOS
• Strong debugging, problem solving, DSA and system design fundamentals
• Clear communication and a self-driven learning style
