Tilt’s mission is simple: Make Commerce Alive.
From static store website builders to impersonal marketplaces, today's ecosystem is ageing fast. It was built for transactional experiences, not for the new generation of merchants who grow through attention, community and personality.
In the UK alone, millions of shoppers, from sneakerheads and Y2K girlies to collectors and parents, have signed up to Tilt. Our platform has helped sellers go from zero to £1M+ in earnings, and hundreds more earn above the UK median income.
And we are just getting started.
We are looking for a Senior Data Architect to own and evolve our end-to-end data platform.
This is a hands-on, high ownership role. You will be responsible for the architecture, reliability, and scalability of our data warehouse, transformation layer, orchestration, and analytics stack.
You will navigate and improve our existing systems across Snowflake, Dagster, dbt, Postgres, Metabase, and ContextFlow, while defining standards that allow us to scale intelligently.
We are not looking for someone who just writes SQL. We are looking for someone who understands data deeply, thinks structurally, and can design systems that last.
Deeply understand our current Snowflake warehouse architecture
Audit and improve existing dbt models for clarity, performance, and correctness
Review and stabilise Dagster orchestration pipelines
Identify data quality gaps and implement testing standards
Ensure key dashboards in Metabase are built on reliable, well-modelled datasets
Document the current system and define architectural standards
Redesign and optimise warehouse architecture where needed
Implement scalable data modelling patterns across domains
Improve cost efficiency and performance in Snowflake
Introduce stronger observability, testing, and lineage practices
Enable AI and product features by structuring high-quality, production-ready datasets
Establish clear version control and deployment workflows for data changes
Partner with product and engineering to define data contracts and ownership
Strong technical background in Computer Science, Engineering, Mathematics or similar. Equivalent practical experience is equally valued
Deeply comfortable navigating modern data stacks, especially Snowflake, dbt, and orchestration tools
Rare combination of analytical rigour and pragmatic execution
You genuinely understand data modelling, not just SQL queries
Highly autonomous. You do not need hand-holding or micromanagement
First principles thinker who questions assumptions and improves systems
Comfortable operating in ambiguity and building structure where none exists
Clear communicator who can explain complex data decisions to non-technical stakeholders
You care about clean systems, reproducibility, and long-term maintainability
Nice to have
Experience with Dagster in production
Familiarity with Postgres operational databases
Experience working with Metabase or similar BI tools
Exposure to AI workflows or tools like ContextFlow
Strong Git habits and version control discipline
Understanding of software development lifecycle and engineering best practices
Experience in fast-moving startup environments
