• Solid understanding of maintainable code, systems design, and software architecture

• Strong experience with library-appropriate, strongly typed languages such as C++, Java, C#, Go, or Rust, along with relevant front-end frameworks
• High adaptability and the ability to learn new technologies quickly
• Interest in modern technologies such as new languages, AI, cloud platforms
• Strong communication skills and confidence working with clients and distributed teams

We Offer
