We're looking for a skilled and ownership-driven .NET (C#) Developer to join our team working on self-driving forklift trucks and Automated Guided Vehicles (AGVs). 

In this role, you will: 

• Dive deep into an existing, complex codebase and lead significant refactoring efforts to improve maintainability, scalability, and performance; 
• Work across multiple interconnected applications, understanding how they communicate with each other and with hardware-level systems (vehicle controllers, sensors, AGV firmware interfaces); 
• Take full technical ownership of your solutions – from design decisions through implementation, testing, and production; 
• Interact directly with the client on a regular basis, contributing to technical discussions, gathering requirements, and communicating progress and trade-offs clearly; 
• Collaborate closely with the Technical Lead to ensure alignment with architecture standards and project goals; 
• Deliver well-tested, production-ready code consistently each sprint; 
• Write accurate estimations and proactively flag risks early. 

Requirements: 

• Strong, proven experience in .NET (C#) development – you should be comfortable working in complex, legacy-touched codebases; 
• Hands-on experience or solid understanding of hardware-level integrations is a strong plus; 
• Experience working across distributed or multi-application architectures; 
• Comfortable owning technical decisions and defending them in front of both internal teams and external clients; 
• Ability to read, understand, and systematically improve existing code – not just write new features; 
• Strong troubleshooting skills and a pragmatic problem-solving mindset; 
• Excellent communication skills - you'll be talking to real people, not just pushing code; 
• At least B2 English level (written and spoken); 
• Team player who thrives in a fast-paced, responsibility-driven environment. 

What will you get? 

• Private health insurance; 
• Sports compensation for gym memberships or online sports subscriptions; 
• Flexible schedule; 
• Education budget for Certifications, Courses, Training and Conferences (a part of the education budget can be spent on gadgets, that stay yours); 
• Books budget; 
• 5 pm Club – a concept developed by ISD to offer 1-hour every week for self-development, development of your ideas and/or presentations to the team to improve public speaking skills.
