Principal Data Architect | £100k + 20% Bonus | Wilmslow / Flexible
We’re partnering with a brilliant B Corp certified data consultancy as they enter their next stage of growth and appoint the most senior technical person in their business.
This is a genuine technical authority role. You’ll own the architecture and system design behind the modern data platforms they build for clients, from initial technical discovery through to deployment, governance and handover.
The work is predominantly greenfield and Databricks-first. You’ll be responsible for defining the target architecture, making the key design decisions and setting the technical quality bar the engineering team builds to.
What you’ll be doing:
- Own the end-to-end architecture of client data platforms and pipelines
- Lead technical discovery and translate requirements into target architectures and sequenced technical roadmaps
- Own and evolve Databricks reference architectures, including ingest patterns, medallion structures, domain isolation, environment topology and deployment patterns
- Design ingestion and integration patterns across ERP, CRM, APIs, SQL estates, files and CDC
- Make architectural decisions across batch, incremental and streaming workloads
- Define engineering standards across Python/PySpark, CI/CD, infrastructure-as-code, testing, code review and environment promotion
- Design for data quality, lineage, observability, metadata, security and governance
- Shape the data foundations and architecture required for AI solutions, including RAG, agents, vector search and data products
- Set non-functional requirements around scalability, performance, cost and security
- Provide technical authority throughout delivery, ensuring what is built stays true to the architecture
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
Technically, we’re looking for someone with strong experience across:
- Databricks, including Delta Lake, Unity Catalog, Workflows, DLT/Lakeflow and SQL Warehouses
- Medallion lakehouse architectures
- Dimensional and data product modelling
- Ingestion and integration architecture, including CDC, APIs, incremental loading and schema drift
- Strong SQL and Python/PySpark knowledge
- Azure data platforms
- CI/CD and infrastructure-as-code, ideally Terraform
- Data governance, quality, lineage and observability
Get help with your application
Your very own career expert that helps elevate your application to the next level.
Experience with Fabric, Snowflake, dbt, Azure DevOps/GitHub Actions, Purview, Atlan, Collibra, MLflow or Mosaic AI would also be valuable, but isn’t essential.
This isn’t a role where you’ll spend your days writing production pipelines. You need to be technically close enough to challenge designs and review engineering work credibly, but your value is in architecture, system-level thinking and technical judgement.
You don’t need to come from consultancy either. Strong in-house architects and platform leads are absolutely of interest. Line management is also optional, so this can remain a deeply technical architecture role.
What’s on offer:
- £100,000 salary
- Up to 20% bonus
- 35 days holiday + bank holidays
- Funded Databricks certification + allocated training time
- Private medical + dental
- Wilmslow office base + flexible working
