🎯 The Role

As a Senior Data Engineer, you will work at the intersection of data, technology, and business, helping our clients turn complexity into clarity and insights into impact.

You will collaborate with multidisciplinary teams in an international environment and contribute to projects that drive performance, innovation, and sustainable growth.

💵 Compensation: £58k to £87k gross/year

💥 Your Impact

In this role, you will:

• Understand client needs and lead delivery end‑to‑end — proposing solutions that solve real business problems across ingestion, transformation, governance, and activation.

• Build and manage scalable pipelines using Snowflake, Fivetran, Gong REST APIs, and Snowpipe.

• Configure AWS S3 raw landing zones and Snowflake External Stages to ensure a durable, immutable raw data layer.

• Deal with semi-structured data and expertly manage JSON/VARIANT payloads in Snowflake, implementing "schema-on-read" patterns to protect against upstream API changes.

• Architect complex dbt models to parse, flatten, and normalise VARIANT data into structured tables.

• Implement logic to merge issuer entities, contact records, and learner profiles across disparate systems to create a "Golden Record."

• Build semantic layers for predictive metrics, including Engagement Scores, Sentiment Trends, and Churn Risk.

• Leverage Snowflake Cortex AI for predictive scoring and surfacing insights.

• Maintain Governance and Security by implementing Role-Based Access Control (RBAC), PII masking (Dynamic Data Masking), and Row-Level Security (RLS) across the Snowflake environment.

• Support clients in their data and digital transformation journeys

⚡ What Makes This Role Challenging

• You will work in complex, evolving client environments

• You are expected to balance delivery quality with pragmatism

• You will collaborate with diverse profiles across functions and cultures

• Autonomy increases with seniority — so does responsibility

👤 What We’re Looking For

Must-haves

• Proven experience in Snowflake (expert level: Snowpipe, Access History, Lifecycle Tags, Cortex AI, External Stages).

• Strong hands‑on experience with dbt (expert in modular modelling, documentation, testing).

• Ability to build ingestion pipelines using AWS S3, Fivetran, Snowpipe, and REST APIs.

• Expertise in Cloud-based architecture (e.g. Azure, AWS)

• Strong analytical and problem‑solving skills, especially in handling JSON/VARIANT and schema‑on‑read patterns.

• Advanced SQL skills (Jinja2 templating is a plus) and working experience with Python for API interactions.

• Demonstrate strong ownership and work independently, taking responsibility for full-project delivery

• Ability to communicate clearly with both technical and non-technical stakeholders

• Fluency in English

Nice-to-haves

• Exposure to Customer 360 (C360) or Sales Intelligence data models (Gong / Salesforce)

• Familiarity with Databricks for data engineering, notebook workflows, or distributed processing

• Experience handling CI/CD pipelines for data workloads (e.g., GitHub Actions, GitLab, Azure DevOps, or similar)

• Knowledge of governance practices, including PII handling, RBAC, RLS, and data cataloguing

• Understanding of reverse ETL concepts and tools

• Experience with Data Viz tools for analytics and dashboarding (e.g. Qlik, Power BI)

• Experience in consulting environments, mentoring and championing best practices

  You meet the core requirements and will need ramp-up time and support.

• Middle of the range
  You are fully autonomous from Day 1 and deliver consistently.

• Top of the range
  You are a reference for the role, mentor others, and raise the bar for the team.

Final offers are based on experience, autonomy, scope, and market context, and are discussed transparently during the process.
