Company: HartleyCo
Apply for the AI Data Engineering Lead
Location: London
Job Description:

We’re partnering with a next-generation AI company that’s reshaping the future of ML and media – blending deep tech with creative excellence. After a series of strategic acquisitions and partnerships, their growth trajectory is steep, and they’re building a best-in-class technical team to scale even faster.

Right now, Data Engineering is their #1 priority.

They’re actively hiring for:

  • Data Engineer
  • Lead / Head of Data Engineering

About the Company:

  • Remote-first culture (timezone-flexibility is key)
  • Backed by top investors and industry leaders
  • Recently acquired a film studio and partnered with a key player in creative AI
  • Hardcore belief in combining technical excellence with creative innovation

Why They’re Hiring: Their AI researchers and scientists are stretched thin, pulled into building foundational data pipelines when they should be focused on modeling. They’re standing up a dedicated Data Engineering team – and they need top talent now to scale their machine learning efforts, especially around video-based models.

What You’ll Work On:

  • Own and scale ML training pipelines (think video datasets at petabyte scale)
  • Curate datasets from messy, unstructured sources – with a focus on automation
  • Architect ingestion systems and build scalable data infrastructure
  • Partner deeply with Infra, AI Research, and Product teams
  • Play a key role supporting projects like foundational model development and synthetic data generation

Tech Stack & Must-Have Skills:

  • Deep experience with ML data pipelines
  • Cloud infrastructure: Terraform, Kubernetes, AWS/GCP/Azure
  • Expertise with petabyte-scale datasets, ideally video-heavy
  • Knowledge of distributed systems and ML data workflows
  • Strong intuition for data quality metrics and ML-native thinking

Bonus Points For:

  • Visual Language Model (VLM) experience
  • Building ML classifiers for data evaluation
  • Automated quality control in training pipelines
  • Familiarity with AI media and synthetic data tools

What They’re Looking For:

  • Systems thinkers who can build and own at scale
  • Startup hustle combined with Big Tech polish (Meta, Google, etc.)
  • Experience leading roadmaps and building from zero to one
  • People who thrive in ambiguity, ownership, and operating without hand-holding

The Process:

  • Initial Call: 30 minutes (schedule-friendly, quick turnaround)
  • Technical Deep-Dive: 90 minutes with an engineering leader
  • Coding Interview: Hands-on session
  • Final Chat: With the CEO and/or CSO

They move fast – and will fast-track standout candidates.
