Key Responsibilities

• Review, annotate, and label code and technical documentation with precision and clarity.
• Evaluate code and machine learning model outputs for correctness, efficiency, and compliance with standards.
• Provide detailed, constructive feedback on code/model outputs, identifying errors, inefficiencies, and areas for improvement.
• Conduct comparative analysis of multiple outputs, ranking them based on correctness, efficiency, readability, and adherence to best practices.
• Validate and correct datasets to ensure data integrity for machine learning and data science projects.
• Collaborate closely with data scientists and engineers to develop guidelines, resolve ambiguities, and maintain high annotation standards.
• Follow complex instructions meticulously and maintain high attention to detail in all tasks.
• Demonstrate strong analytical and troubleshooting skills to address technical challenges.
• Communicate findings and feedback in clear, actionable written form.
• Proactively identify opportunities for process improvement and challenge the status quo where necessary.

Required Qualifications

• Technical Background: Degree or substantial experience in software engineering, computer science, machine learning/artificial intelligence, or a related technical field.
• Programming Proficiency:
• Expertise in Python (mandatory).
• Proficiency in at least one other common programming language (JavaScript, Node.js, Typescript, C, C++, Shell).
• Familiarity with at least one less common language (Rust, Go, Ruby, Swift, PHP, Kotlin, Shell).

Web Technologies:

Strong knowledge of HTML, CSS, and JavaScript.

Hands-on experience in web application development (e.g., Flask).

Understanding of frontend (React) and backend (Node.js) development.

ML/AI Knowledge:

Understanding of machine learning concepts, model development, experimentation, training, and evaluation.

Familiarity with deep learning frameworks (TensorFlow, PyTorch, Keras, JAX) and architectures (CNN, RNN, transformers, LSTM).

Experience in natural language processing (NLP) and reinforcement learning (PPO, Q-learning, policy gradients, DQN, AlphaZero, A2C).

Exposure to computer vision (image processing, segmentation, OCR, deepfake detection) and game AI.

Data Science & Engineering:

Proficiency in data analysis and manipulation using Pandas, Matplotlib, Seaborn, NumPy, and statistical analysis/visualisation tools.

Experience with database management (SQL, NoSQL, SQLite).

Algorithms & Mathematics:

Knowledge of general and specific algorithms (e.g., MCTS, A*, Sudoku, Collatz, optimisation, combinatorial problems).

Preferred Qualifications

• Experience with large language models (LLMs) and code generation technologies.
• Familiarity with various programming paradigms, including object-oriented and functional programming.
• Experience in code review within professional or academic settings.
• Prior experience in data annotation or quality assurance roles.

Location & Working Hours

This position is open to candidates based in India or those comfortable working with Indian teams and time zones. Flexibility for remote work may be available.
