• Developing user-oriented features and technical components in a high-performance, scalable architecture.
• Writing unit tests, participating in code reviews, and supporting continuous integration using tools like Jenkins.
• Working closely with global technology and trading teams to ensure timely, quality delivery.

You will be best suited for this role if:

• You have 3+ years of hands-on experience in C# development, ideally in real-time or performance-critical environments.
• You have a strong command of .NET Framework and are confident building modern backend applications from scratch.
• You are comfortable working with low latency systems and understand performance optimization techniques.
• You are experienced with Agile methodologies, test-driven development (TDD), and continuous integration practices.
• You are proficiency in English.

Your future with Société Générale will include:

• Work in a pleasant atmosphere as part of an international team in a brand-new office in the center of Warsaw, designed with facilities for people with disabilities.
• An active role in an international structure and the opportunity for growth.
• Access to educational platforms and language courses.

• Competitive salary based on seniority and skills.
• Support in quick adaptation in the company.
• Extraordinary health package with extensive dental care.
