About the role
- Software Engineering & Coding Challenge Development
- Design realistic, technically challenging programming tasks based on practical software engineering scenarios
- Develop self-contained coding problems involving bug fixes, feature implementation, refactoring, and performance optimisation
- Apply expertise in Python 3, Java, Rust, Go, C++, TypeScript, or comparable programming languages
- Analyse unfamiliar codebases and translate technical requirements into clear, implementable engineering objectives
- Create coding challenges that reflect authentic software development workflows, system constraints, and engineering best practices
- Reinforcement Learning Environments & Deterministic Verification
- Build reproducible reinforcement learning environments for evaluating advanced AI coding capabilities
- Design deterministic verification systems that correctly recognise valid software implementations
- Develop comprehensive automated tests that identify incorrect solutions while accepting reasonable alternative implementations
- Produce accurate golden reference solutions for assigned programming challenges
- Validate evaluation environments for reproducibility, technical correctness, and consistency with specified requirements
- Backend Development & Feature Engineering
- Develop and evaluate backend services, APIs, and supporting application components
- Implement robust software features while maintaining scalability, reliability, and code quality
- Apply appropriate algorithms, data structures, and software design principles to complex engineering problems
- Assess code architecture, system behaviour, and implementation decisions against technical requirements
- Contribute practical development expertise to realistic feature delivery and software engineering scenarios
- Debugging, Refactoring & Performance Optimisation
- Investigate complex software defects, implementation errors, and performance bottlenecks across diverse codebases
- Apply systematic debugging approaches to identify underlying issues and implement effective corrections
- Refactor existing and legacy code to improve readability, maintainability, efficiency, and long-term reliability
- Evaluate computational performance, runtime behaviour, and software resource utilisation
- Verify engineering improvements through automated testing, reproducible execution, and structured technical analysis
- Code Review, Technical Documentation & Quality Assurance
- Review programming solutions and technical submissions for correctness, clarity, efficiency, and maintainability
- Evaluate peer-contributed code and provide precise, actionable engineering feedback
- Document technical reasoning, implementation decisions, debugging strategies, and verification methodologies
- Communicate sophisticated software engineering concepts through clear written explanations and structured evaluations
- Maintain high standards of technical accuracy, reproducibility, and documentation quality across assigned deliverables
- Ideal Profile
- Significant hands-on experience in professional software engineering, particularly backend development and complex application systems
- Demonstrated expertise in at least one of the following programming languages: Python 3, Java, Rust, Go, C++, or TypeScriptStrong understanding of algorithms, data structures, computational complexity, and foundational computer science principles
- Proven experience developing scalable backend services, APIs, and production software applications
- Practical expertise in debugging, automated testing, code review, and technical problem-solving
- Demonstrated ability to identify and resolve complex software defects and system performance bottlenecks
- Experience implementing substantial features within existing applications or large-scale codebases
- Strong understanding of software architecture, refactoring, maintainability, and legacy system modernisation
- Experience designing reproducible tests and validating implementations against technical specifications
- Ability to develop objective acceptance criteria and explain why a programming solution satisfies defined requirements
- Demonstrable GitHub or comparable open-source contributions are preferred; candidates without a sufficiently representative portfolio may complete an alternative HackerRank assessment
- Experience contributing to open-source repositories, reviewing pull requests, or maintaining collaborative software projects is highly relevant
- Strong analytical reasoning, logical thinking, algorithmic problem-solving, and independent engineering judgement
- Ability to navigate unfamiliar codebases and understand complex technical requirements efficiently
- Excellent technical documentation skills, including the ability to explain programming decisions and software modifications clearly
- Strong written communication and constructive code review capabilities
- Experience working independently on technical assignments and producing reproducible software deliverables
- Familiarity with reinforcement learning environments, coding benchmarks, or AI software engineering evaluation is advantageous
- Interest in advanced AI technologies and automated programming systems is beneficial
- Prior experience with AI model training or evaluation projects is not required
- Engagement Details
- Freelance / contract engagement
- Fully remote - open worldwide
Before you apply
Applying takes about a minute. These four things decide how fast it moves after that.
Your profile is current
It's what we read first. Occupations, seniority and locations matter more than a long history.
Two examples you can talk through
Not a portfolio — just two pieces of work where you can explain the decisions and what you'd change.
A number in mind
What you're on now and what would make you move. We negotiate better when we know both.
Your notice period
Employers plan around it, and it's the question that stalls offers most often.
Once you apply, someone reads it and calls you before anything reaches the employer — usually within two working days.
