Data Architect Python (ESP/UK)

Stack

Responsibilities

• ▹Assess data sources, structures, and quality across multiple systems
• ▹Define data ingestion, mapping, and transformation strategies to unify disparate datasets
• ▹Design target data architecture to support a scalable MVP (e.g. multi-source integration, golden record approach)
• ▹Identify gaps, risks, and constraints in current data that impact product feasibility
• ▹Define data models, schemas, and integration patterns aligned to product requirements
• ▹Establish approaches for data governance, lineage, and quality management
• ▹Collaborate with product, UX, and engineering to ensure architecture supports user needs and workflows
• ▹Work directly with datasets to validate assumptions and inform architecture decisions
• ▹Support prototyping of data flows, pipelines, and transformations
• ▹Contribute to early-stage technical solutions where required (Python, SQL, etc.)
• ▹Work closely with stakeholders to understand data ownership, constraints, and priorities
• ▹Support user research and validation by ensuring data feasibility aligns with product concepts
• ▹Translate complex data challenges into clear, actionable insights for non-technical stakeholders

Requirements

• ▹Proven experience as a Data Architect, Senior Data Engineer, or similar
• ▹Strong experience working with fragmented or multi-source data environments
• ▹Ability to operate in discovery / early-stage product definition, not just implementation
• ▹Experience designing scalable data architectures for analytics or decision-support products
• ▹Strong communication skills, able to bridge technical and product discussions
• ▹Familiarity with data governance, mapping, and data quality challenges
• ▹Strong proficiency in Python and SQL
• ▹Experience with cloud-based data platforms (AWS, GCP, or Azure)
• ▹Understanding of data pipeline design, ETL/ELT patterns, and distributed systems
• ▹Experience with data modelling, schema design, and integration patterns

Nice to have

• ▹Exposure to modern data architectures (e.g. medallion, event-driven, or similar)
