We’re looking for a CRM Engineer (Data & Platform) to join our CRM team in London. You’ll support our global CRM team by building, maintaining, and improving the data and platform infrastructure that powers reliable, scalable CRM.

In this role, you’ll focus on the technical foundations behind CRM, combining data engineering, platform architecture, and CRM systems understanding to ensure customer data is reliable, activation-ready, and easy to work with across our ecosystem.

You’ll work across Kafka event streams, Snowflake, Braze, internal tools, and supporting integrations to transform raw product and customer data into trusted CRM-ready datasets, scalable activation systems, and effective CRM execution.

You’ll often be the person the team turns to when something doesn’t look right, whether that’s a data inconsistency, event flow issue, customer attribute problem, integration failure, or CRM platform behaviour that doesn’t align with expectations. You enjoy solving technical problems methodically, working across systems, and improving the infrastructure that powers CRM long term.

Here’s how you’ll be contributing to the CRM team:

Support the ingestion, transformation, and modelling of event-driven customer data within Snowflake to create and maintain CRM-ready datasets
Build and maintain reliable data flows from Kafka into Snowflake and onward into CRM activation platforms
Validate event payloads, schemas, identifiers, timestamps, and data quality before they are used for CRM targeting or personalisation
Support and improve CRM data pipelines, activation architecture, and platform integrations across Kafka, Snowflake & CRM platforms
Validate and troubleshoot customer data flows, events, attributes, and personalisation logic to ensure CRM reliability
Support the day-to-day technical operation, implementation, and optimisation of our CRM ecosystem, including Braze, internal tools, and supporting platforms
Act as a technical partner to CRM stakeholders, helping translate lifecycle and marketing requirements into scalable data and platform solutions
Identify and resolve issues across data architecture, integrations, campaign logic, and platform performance
Improve CRM segmentation, targeting, and activation reliability through stronger data engineering, modelling, and governance
Contribute to QA processes, documentation, operational workflows, and technical best practices
Share knowledge that improves the wider team’s understanding of CRM data and platform capabilities
Build, support, and troubleshoot Braze campaigns, audience logic, data structures, and platform configurations to ensure reliable CRM execution

This role will give you the opportunity to:

Build technical depth: Work across CRM data architecture, Kafka event streams, Snowflake engineering and modelling, activation systems, and CRM platform infrastructure
Solve meaningful problems: Diagnose and improve the systems that power customer communications globally
Have visible impact: Build stronger CRM foundations that improve reliability, scalability, and execution
Improve how the team works: Help shape better data governance, QA, and operational maturity across CRM

Qualifications

About you:

You have 5+ years experience working in data, CRM technology, MarTech, or platform engineering roles
You have strong SQL, data engineering, and data modelling experience (Snowflake or similar preferred)
You have experience working with Kafka or similar event-streaming systems, or strong transferable experience working with event-driven customer data within Snowflake or similar data environments
You have hands-on experience working with CRM or customer engagement platforms (Braze strongly preferred), including campaign builds, audience logic, data structures, and platform implementation
You understand how customer data, attributes, events, and integrations power CRM systems
You’re comfortable troubleshooting technical issues across data, APIs, integrations, and platform logic
You approach problems methodically and enjoy working across both data systems and operational platforms
You communicate clearly and can translate technical complexity into practical solutions
You’re proactive about improving documentation, governance, workflows, and system reliability
