Role overview
Maincode is hiring a Signal Engineer to own the quality of the training data used by Matilda, an Australian large language model.
The role combines data engineering with editorial judgment and focuses on turning raw data into high-quality training datasets.
What you will work on
- Build pipelines that ingest, clean, deduplicate, filter, and score training data at terabyte to petabyte scale.
- Develop quality classifiers and heuristics that separate useful data from the rest.
- Design dataset mixtures and experiment on what improves model performance.
- Build tools to explore, sample, and audit the training corpus.
- Work closely with researchers and training engineers so data choices connect to model behaviour.
What Maincode is looking for
- Strong engineering skills in Python, data tooling, distributed processing, and clean pipelines.
- High attention to detail and judgment about what good training data looks like.
- Comfort working with very large, messy datasets.
- Curiosity about how data shapes model behaviour and a high learning velocity.
- A PhD or prior LLM experience is not required.
