Software Engineer - Backend

Our client is an innovative technology organization developing advanced artificial intelligence systems through real-world software engineering challenges.

The organization works with experienced software engineers to improve the coding, reasoning, debugging, and problem-solving capabilities of next-generation AI models.

For this project, our client is seeking skilled Backend Software Engineers with expertise in Python, Java, Rust, Go, C++, or TypeScript to develop realistic coding challenges, reproducible testing environments, and reliable evaluation frameworks.

CONFISA Group is supporting the recruitment of qualified professionals for this fully remote, project-based opportunity.

Our client is seeking experienced Backend Software Engineers to contribute to an innovative artificial intelligence project focused on improving the coding, reasoning, debugging, and problem-solving capabilities of next-generation AI models.

In this fully remote, project-based contractor role, you will develop Reinforcement Learning Environments that challenge advanced AI systems to solve realistic software engineering problems.

You will design complex coding tasks based on real-world repositories, create reproducible development environments, implement reliable verification mechanisms, and provide reference solutions.

Previous experience in artificial intelligence is not required. Strong practical software engineering expertise is the primary qualification.

Key Responsibilities

• Design realistic and technically challenging software engineering tasks based on existing code repositories.

• Develop complex programming challenges involving subtle bugs, non-trivial feature implementations, codebase refactoring, and performance optimization.

• Create reproducible development and testing environments for each assigned task.

• Design and implement deterministic verifiers that recognize valid solutions while rejecting incorrect, incomplete, or hard-coded implementations.

• Develop reference solutions demonstrating how each engineering challenge can be successfully resolved.

• Apply advanced knowledge of algorithms, data structures, and software engineering principles.

• Ensure coding challenges require genuine engineering problem-solving rather than simple lookups or boilerplate implementations.

• Identify and report ambiguous, incomplete, or unverifiable tasks.

• Produce clear technical documentation describing task requirements, expected outcomes, and verification criteria.

• Work independently and asynchronously while maintaining high standards of technical quality.

• Experience implementing non-trivial software features and improving existing applications.

• Strong knowledge of codebase refactoring, software maintenance, and performance optimization.

• Ability to work with existing code repositories and understand complex codebases.

• Experience developing reproducible development and testing environments.

• Ability to design reliable, deterministic tests that validate correct implementations and identify incorrect or incomplete solutions.

• Strong analytical and problem-solving skills.

• Excellent technical documentation and written communication abilities.

• Ability to work independently in a remote, asynchronous, project-based environment.

Preferred Qualifications

• Experience working with large-scale software systems or complex backend architectures.

• Demonstrated success modernizing legacy applications and refactoring large codebases.

• Track record of delivering high-impact software features from initial design through implementation.

• Experience designing complex coding challenges, test cases, or automated verification frameworks.

• Familiarity with software performance profiling, debugging tools, and optimization techniques.

• Interest in artificial intelligence, reinforcement learning, and advanced AI coding systems.

• Ability to explain technical decisions, document solutions, and communicate complex engineering concepts clearly.

Additional Requirements

• Availability to dedicate approximately 15 hours per week to project assignments.

• Ability to produce high-quality technical deliverables that meet defined project specifications.

• Willingness to complete technical screening and an AI-based interview as part of the selection process.

• Availability to begin assignments promptly following successful onboarding.
