.NET/C# Developer

About this job

This person will join a specialized R&D team that is pioneering high-accuracy micro-location technologies that rely on advanced algorithms to achieve centimeter-level precision. By blending sensor data, RF signals, and cutting-edge signal processing, they are transforming how people and machines navigate their environments. This person will join a team to tackle complex real-world problems with creativity, collaboration, and a spirit of continuous innovation.

Basic knowledge (foundational prerequisites)

1. Programming fundamentals : variables, control flow (loops, conditionals), functions/methods, recursion, error handling, and basic data structures (arrays, lists, dictionaries).
2. Object-oriented principles : encapsulation, inheritance, polymorphism, abstraction, and common design patterns (e.g., factory, singleton, observer).
3. Operating system basics : process vs. thread, concurrency primitives (locks, semaphores), file systems, environment variables, and command-line usage (Linux bash or Windows PowerShell).
4. Networking essentials : OSI model (especially layers 3 & 4), IP addressing, ports, TCP vs UDP, DNS, request/response cycle, and common troubleshooting tools (ping, netstat, curl).
5. Version control : daily Git usage – cloning, committing, branching, merging, rebasing, and pull requests.
6. Database fundamentals : SQL syntax (SELECT, JOIN, GROUP BY), indexing basics, and understanding of transactional vs. analytical workloads.
7. Security hygiene : principle of least privilege, secure password storage (hashing + salting), environment variables for secrets, and basic understanding of TLS/SSL.
