Alignerr Corp.; Wollongong City Council; A distancia; AUD 79.000 - 237.000; A tiempo parcial

Descripción de la vacante

Alignerr is seeking a Data Scientist (Masters) to audit, challenge, and improve cutting-edge AI systems in a fully remote hourly contract. You will design advanced, domain-specific data science problems and craft ground-truth solutions with Python, SQL, and R.

The role emphasizes rigorous evaluation and clear documentation of model limitations. You will audit AI-generated code across Scikit-Learn, PyTorch, and TensorFlow, offering actionable feedback to improve how models reason, while

Formación

• Pursuing or holding a Master’s or PhD in Data Science, Statistics, Computer Science, or a quantitative field with heavy emphasis on data analysis
• Strong foundational knowledge across core areas - supervised and unsupervised learning, deep learning, big data technologies (Spark/Hadoop), or NLP
• Able to communicate complex algorithmic concepts and statistical results clearly and precisely in writing
• Naturally detail-oriented - you catch errors in code syntax, mathematical notation, and statistical conclusions that others miss
• No prior AI or data annotation experience required

Responsabilidades

• Design advanced challenges - craft complex, domain-specific data science problems spanning hyperparameter optimization, Bayesian inference, cross-validation strategies, dimensionality reduction, and more
• Author ground-truth solutions - build rigorous, step-by-step technical solutions with Python/R scripts, SQL queries, and mathematical derivations
• Audit AI-generated code - evaluate AI outputs across libraries like Scikit-Learn, PyTorch, and TensorFlow for correctness, efficiency, and technical soundness
• Sharpen AI reasoning - identify logical failures in AI outputs and provide structured, actionable feedback to improve model reasoning
