London (Hybrid)

Q1 Start Initial 6 months

Outside IR35 - rate depending on experience

We’re working with a fast-growing AI company looking for a Senior, hands-on Data Software Engineer ML/AI to take ownership of their data pipelines and strategy, sitting at the intersection of software engineering, data engineering and machine learning.

Today, data ingestion and optimisation is handled ad-hoc by ML engineers, the goal is to industrialise this into robust, scalable, daily pipelines that can support rapid model development without storage or cost bottlenecks.

What you’ll be doing

Designing and owning end-to-end data pipelines, from data sourcing through to ML-ready datasets
Building and maintaining web scraping and ingestion pipelines to ensure fresh, up-to-date data feeds into models on a daily basis
Working heavily with audio and transcript data pairs at scale
Optimising data storage and retrieval to improve cost, performance, and scalability
Improving the efficiency and throughput of the ML team by removing data bottlenecks
Establishing a clear data strategy: what data is collected, how it’s sourced, stored, versioned and governed
Collaborating closely with ML, MLOps, platform and infrastructure teams
Taking ownership in an environment without an established data engineer

What we’re looking for

Strong experience as a Software Engineer working on Data & AI problems
Proven ownership of scraping, ingestion and data pipeline design (not just SQL / data lake work)
Advanced Python skills; solid SQL where needed
Experience building data systems that directly support machine learning workflows
Cloud experience (any major provider) and comfort working close to infrastructure
Ability to operate independently, define best practice and move fast in an evolving environment
