Senior Machine Learning Engineer- Multimodal Data
Requirements and responsibilities
Readable role content extracted into sections for faster review.
What you'll do
- Design and build data pipelines for agent training: collection, filtering, deduplication, formatting, and versioning across text, image, and multimodal sources.
- Build and maintain infrastructure for efficient data loading, storage, and retrieval at scale (S3, distributed systems, streaming pipelines).
- Collaborate with research scientists to translate research requirements into concrete data specifications, and iterate as experiments reveal new needs.
- Create evaluation datasets and benchmarks in collaboration with researchers—curating task distributions that surface real failure modes.
- Develop tooling for dataset construction—including human annotation workflows, synthetic data generation, and preference data collection for RLHF/DPO-style training.
- Own data quality: build validation frameworks, monitor for drift and contamination, and establish standards that make datasets trustworthy and reproducible.
- Document datasets thoroughly: provenance, known limitations, intended use cases, and versioning history.
- Implement comprehensive test coverage for data pipelines and ML workflows, ensuring reliability and catching regressions early.
- Elevate codebase quality through code reviews, refactoring, and establishing engineering best practices that help research velocity scale sustainably.
- Contribute to team roadmaps by identifying data bottlenecks and proposing solutions that unblock research velocity.
You're likely a match if you have
- Strong software engineering skills in Python, with experience building production-grade data pipelines and ML DevOps.
- Practical experience with prompt engineering—designing, testing, and refining prompts for reliable LLM/VLM outputs.
- Experience with ML data workflows: large-scale data processing and loading (Ray, or similar), data versioning, and format considerations for training (tokenization, batching, sharding).
- Hands-on experience working with data pipelines for large-scale distributed ML training runs.
- Familiarity with annotation tooling and human-in-the-loop data collection (Label Studio or internal systems).
- Understanding of ML training requirements—you know what "good data" looks like for LLM/VLM fine-tuning and can anticipate downstream issues.
- Experience loading and writing large datasets to/from cloud infrastructure (AWS) and distributed storage systems.
- Strong communication skills: you can work with researchers to scope ambiguous problems and translate needs into actionable plans.
- A collaborative approach, comfortable taking ownership and iterating quickly.
Nice to haves
- Experience with preference data collection for RLHF or reward modelling.
- Familiarity with multimodal data (image-text pairs, video, design assets).
- Experience building synthetic data generation pipelines using LLMs.
- Background in data quality metrics and monitoring systems.
- Contributions to dataset releases or benchmarks in the ML community.
Here's a taste of what's on offer:
- Equity packages - we want our success to be yours too
- Inclusive parental leave policy that supports all parents & carers
- An annual Vibe & Thrive allowance to support your wellbeing, social connection, office setup & more
- Flexible leave options that empower you to be a force for good, take time to recharge and supports you personally
