We're looking for a talented data warehouse developer to join our growing data team and help unify our data landscape into a single source of truth powering MI, deep-dive analyses and machine learning predictive models. 

This is a fantastic opportunity for a Data Warehouse Developer with a penchant for data modelling to be an integral part of a thriving, profitable business, and help build a world-class data infrastructure that will be transformational for our people and our customers.  The core set of Truth tables you will help build will:

  • Power deep-dive analyses to answer questions that unlock the next growth lever for the business
  • Enable analysts to become data champions in their respective teams
  • Enable fast, easy, self-serve BI in every team, helping everyone to spend time on what really matters
  • Flow straight into our data-science powered personalisation technology

How the magic happens 

We collect data from dozens of data sources, ranging from transactional data, availability data, payments data, customer event-level data, voice-of-customer data, third party data and much much more. Our historical data runs into tens of billions of records and grows at a rate of tens of millions of records every day. 

Our data is extremely varied, some being very finely-grained, event-level data, other being already aggregated to various degrees. It also arrives on different schedules!

Things you will be working on 

  • Unify heterogeneous, raw data sources into analytically-friendly tables to support deep dive analyses (single customer behaviour view, marketing attribution, performance drivers etc.).
  • Build and maintain complex business logic in SQL
  • Help to design, implement, optimise, evolve, support and deploy new and existing data models to support use-cases across MI, analysis and data science.
  • Work cross-functionally with data scientists, marketing and commercial analysts to understand the business problems being tackled, the structures and relationships in our raw data, and translate the business logic into SQL.
  • Take ownership and responsibility for implementing the business logic in SQL, testing code and logic thoroughly and ensuring best practices are used throughout - particularly with regard to self-explanatory code, maintainability and scalability.
  • Work cross-functionally to integrate BI platforms onto our data warehouse, developing the schemas, aggregations and any data models sitting between the warehouse and business users.
  • Support and coach analysts and data scientists on using SQL for data modelling and analysis.
  • Work with fellow data engineers to help productionise analyses that are contributed by analysts and data scientists.

The Deal Breakers 

  • You live and breath SQL for data modelling.
  • Proficient in writing performant, high quality, maintainable SQL code on large and very large datasets.
  • Able to explore large, heterogeneous datasets of raw data to uncover their structure and understand the relationships.
  • Understand the practical complexities of implementing deeply custom business logic rules, what can go wrong and preventative measures.
  • Meticulous, careful validation of every join and intermediate table you create.
  • You have experience of setting up and working with modern BI tools  (e.g. Looker, Tableau, Power BI, etc)

And you are...

  • Pro-active with a self-starter mindset; able to identify elegant solutions to difficult problems and able to suggest new and creative approaches.
  • Analytical, problem-solving and an effective communicator ; leveraging technology and subject matter expertise in the business to accelerate our roadmap.
  • Able to document business logic clearly, in plain English, in the code itself, making knowledge easily transferable to the wider team. 
  • Highly collaborative in work style
  • Curious and inquisitive
  • Willing to step outside your comfort zone to broaden your skills and learn new technologies

Nice to have 

  • Comprehension of data modelling techniques (one or more of Star Schema, Kimball, Data Vault etc)
  • Some experience with Python as this is the engineering wrapper for all our SQL (you will be supported by fellow data engineers)
  • Experience with MPP cloud data warehouses a big plus (Amazon Redshift, Snowflake)
  • Experience or at least familiarity with modelling use-cases such as sessionisation and identity stitching a plus.
  • Good understanding of Agile

Our stack

Our stack is Python for the data pipeline, Airflow for orchestration and Snowflake is our data warehousing technology of choice. This is a chance to work with best-of-breed ETL/data warehousing tools and technologies. Our wider ecosystem of tools and partners includes Snowplow, Spark, Docker. Everything runs in AWS.

We are an equal opportunity employer:

Diversity and inclusion are important to us at Secret Escapes and we encourage a culture where everyone can be themselves at work. We value and actively seek out a richly diverse range of talent and our policies ensure that every job application and employee is treated fairly, with equal opportunity to succeed.
