• Identify and address software security risks through secure coding, vulnerability management and appropriate testing practices.
• Develop and maintain automated tests, including unit tests, to ensure software reliability and quality.
• Improve CI/CD pipelines and development workflows to support efficient and secure software delivery.
• Apply software design patterns and engineering best practices to solve complex technical challenges.
• Collaborate with scientists, product managers and cross-functional engineering teams to translate scientific and customer needs into practical software solutions.
• Provide technical guidance to other engineers, participate in code reviews and support continuous improvement across the team.
• Contribute to technical documentation, including cybersecurity implementation and verification evidence.

What We're Looking For

• University degree in Computer Science, Software Engineering or a related technical field with 6+ years of professional software development experience.
• Strong professional experience with C# and C++, including the development and maintenance of complex software applications.
• Solid understanding of software cybersecurity, secure development practices and software vulnerability management.
• Experience with CI/CD practices and automated software delivery workflows.
• Strong collaboration and communication skills, with the ability to work effectively across engineering and non-engineering teams.
• Practical experience using Git for version control.
• Strong understanding of unit testing, software quality assurance and automated testing practices.
• Good knowledge of software design patterns, architectural principles and maintainable software design.
• Excellent analytical thinking and problem-solving skills, with the ability to troubleshoot complex software challenges.
• Experience with Python for software development, scripting or automation.
• Proven ability to provide technical guidance, influence engineering decisions and work independently on complex projects.

What We Offer

• Flexible working hours to support your work-life balance.
• 25 days of vacation and 5 sick days per year.
• Financial benefits, including an annual bonus, pension contributions, and preferential rates on life and health insurance.
• Discounted mobile plans for you and your family.
