Remote | Senior Software Engineer — $50–$100/hour
About The Position
We are sharing a specialised consulting opportunity for experienced Senior Software Engineers with strong expertise in Python3, Java, Rust, Go, C++, TypeScript, algorithms, debugging, feature development, codebase refactoring, and performance optimisation to contribute to an advanced AI training and software-engineering evaluation project. Selected professionals will create reinforcement-learning environments that test advanced AI systems on realistic software-engineering problems involving bug fixing, feature implementation, refactoring, and performance optimisation. Each environment will require a reproducible technical setup together with a high-quality golden reference solution demonstrating the expected engineering approach. No prior experience in AI is required.
Requirements
- Significant professional software-engineering experience
- Strong hands-on expertise in at least one of Python3, Java, Rust, Go, C++, or TypeScript
- Deep understanding of algorithms and data structures
- Strong command of software-engineering fundamentals
- Proven ability to debug complex systems and resolve difficult defects
- Experience implementing substantial product or platform features
- Strong background in codebase refactoring and legacy-system modernisation
- Experience identifying and resolving performance bottlenecks
- Ability to reason across large and unfamiliar codebases
- Strong technical documentation and communication skills
- Experience taking high-impact features from concept through delivery is highly valuable
- Comfortable reviewing and validating other engineers' work
