• A good understanding of consistency, reliability, scalability of systems without downtime;
• An understanding of design patterns and API design;
• Experience in system design, design patterns, API design and implementation of large scale distributed systems in the cloud, from IaaS containers to PaaS;
• Experience in system reliability and stability patterns;
• Hands-on experience with both SQL and NoSQL databases;
• The know-how to write readable, idiomatic, and maintainable C#;
• Experience implementing sophisticated API products;
• Experience with agile methodologies.

Nice to haves:

• Experience in building high-performance API products;
• Experience launching APIs to both internal and external consumers;
• Experience building cloud systems (specially Azure).

You’ll be:

• A T-shaped engineer, but will major in C#;
• Product oriented;
• Focused on quality and will know what it means to ship high-quality code;
• Self-motivated, proactive and always looking for ways to improve yourself, the team and the product;
• Diplomatic and emotionally intelligent, you’ll have the ability to listen and be open to others’ points of view;
• A good communicator, both in writing and verbally. You’ll be able to explain technical ideas and concepts in business-friendly language;
• A genuine believer in diversity, fairness, and including everyone;

What you’ll get in return:
