Senior Python Developer

What you'll do

This is data work for a foundational LLM company, done by someone who can really read Python. The ad explains the two kinds of output. For supervised fine-tuning you write or receive a prompt with code and questions, produce model responses and write the Python that solves them. For RLHF you pose questions to a model, compare two versions' outputs and write the feedback that goes back into training. The ad is explicit that you will not be building or fine-tuning LLMs.

Day to day it lists:

• Writing and maintaining clean Python for training and optimisation
• Running evaluations and analysing model performance
• Ranking AI responses to queries against set criteria and writing rationales
• Creating task-specific SFT datasets and optimal reference responses
• Working with researchers and annotators on RLHF and reward models
• Peer-reviewing code and documentation

Who fits

• 3+ years of strong Python
• Industry experience with code quality, formatting and good practice
• Experience with Python testing (unit, integration, property-based)
• Knowledge of multi-threading and async Python
• Comfort refactoring architecture without regressions, and debugging memory and concurrency issues
• Fluent conversational and written English

What it pays

The ad does not publish a rate. Turing sets rates per project, so the figure comes after matching; see Turing for how pay generally works there.

Worth knowing

Good:

• Hours are your choice of three options: 20, 30 or 40 a week
• Code-centric work with a stated evaluation process
• Fully remote

Less good:

• No rate published
• Initial term is 1 month, start expected the following week
• Minimum 4 hours a day with 4 hours of overlap with Pacific Time
• Contractor assignment with no medical or paid leave
• Long-running posting (first listed in January 2024), so the project may already be staffed in places

How hiring works

The ad describes about 75 minutes of evaluation: a 60-minute technical interview plus a 15-minute cultural and offer discussion.
