Senior Data Engineer

Hush is an ambitious and distinctive fashion brand, with plans to double the business over the next few years. Founded 21 years ago, we are now established as one of the UK’s leading online fashion retailers. We employ around 150 employees across head office and retail, creating and selling a beautiful range of women’s clothing and accessories characterised by effortlessness, simplicity and a laidback sense of style. Despite the challenges to the retail industry, Hush has continued grow – and our company culture still reflects our entrepreneurial roots and relaxed aesthetic. We love hard-working and talented people with a can-do attitude and a passion for what they do.

As Hush continues to grow, we're investing heavily in our data capability and are looking for a commercially-minded Senior Data Engineer to help evolve our data platform, insight capabilities and AI-driven ways of working.

This is not a traditional engineering role.

We're looking for someone who combines strong technical foundations with commercial curiosity – someone who enjoys understanding how a business works, partnering with stakeholders, asking the right questions and turning data into meaningful action.

You may already be operating at Senior Data Engineer level, or you may be an experienced Data Engineer who is ready to take that next step. What matters most to us is that you've proved yourself, take ownership, have the right energy and attitude, and are hungry to make an impact.

You’ll play a key role in developing our data platform, supporting strategic decision-making across the business and helping us explore how AI can make our data function faster, smarter and more effective.

What You’ll Be Doing

Build & Evolve Our Data Platform

• Contribute to the architecture and development of our modern data platform, including data warehouse, modelling layer and pipelines.
• Develop and maintain high-quality data models and pipelines.
• Help establish best practices across data modelling, testing, governance and documentation.
• Ensure our data platform remains secure, scalable and high-performing.
• Take ownership of projects and see them through from idea to delivery.

Partner with the Business

• Work closely with Commercial, Merchandising, Marketing and Operations teams to understand priorities and identify opportunities where data can drive better decisions.
• Translate business challenges into practical data solutions.
• Build strong relationships with stakeholders and communicate insights clearly.
• Challenge assumptions and help the business understand what the data is really telling us.
• Help drive a more data-led approach to decision-making across the business.
• Move quickly from idea to insight, testing hypotheses and delivering clear recommendations.
• Support analysis including customer segmentation, predictive modelling, cohort analysis and customer lifetime value modelling.
• Look for new ways to use data to solve real commercial problems.

Shape How We Use AI

• Help us develop how the data team uses AI-assisted development.
• Explore and champion tools such as Cursor and emerging AI technologies.
• Establish good practices around using AI to improve speed, quality and efficiency.
• Stay curious about new technologies and identify where they can genuinely add value.

Develop & Share Knowledge

• Work closely with our Junior Data Engineer, providing support, guidance and mentoring.
• Contribute to code reviews and share good engineering practices.
• Help build capability and raise the quality of our data engineering function.

Champion a Data-Driven Culture

• Maintain and develop reporting models and BI solutions.
• Enable self-service analytics across the business.
• Partner with Marketing to support customer data and insight.
• Help make data more accessible and useful to people across Hush.

What We’re Looking For

We’re looking for someone with strong technical foundations, commercial curiosity and the ambition to grow. You might already be a Senior Data Engineer, or you could be an experienced Data Engineer who is ready for their next step. Either way, we’re more interested in what you’ve delivered and your potential than simply the number of years you’ve been doing it.

You’ll ideally have:

• Experience working within e-commerce, retail, fashion or another fast-moving consumer environment.
• Strong SQL skills and solid data modelling capability.
• Hands-on experience with dbt.
• Experience working with modern cloud data warehouses such as BigQuery.
• Experience with BI platforms such as Power BI, Looker, Superset, Preset or Qlik.
• Experience using Python alongside SQL.
• An understanding of statistical analysis and machine learning techniques.
• Experience working with business stakeholders and translating commercial questions into data solutions.
• The ability to explain technical concepts clearly to non-technical audiences.
• A genuinely commercial mindset and an interest in how data can influence business performance.
• Curiosity, creativity and a passion for solving problems.
• Confidence taking ownership and working independently, while knowing when to collaborate and ask for support.
• An interest in AI and modern engineering practices.

Most importantly, we’re looking for someone who:

• Has already demonstrated that they can deliver and make an impact.
• Takes ownership rather than waiting to be told what to do.
• Has good energy, a positive attitude and a willingness to get stuck in.
• Is commercially curious and wants to understand the ‘why’, not just the technical ‘how’.
• Enjoys working with people as much as working with data.
• Is ambitious and excited by the opportunity to step up and grow.
• Is comfortable working in a fast-moving environment where things are still evolving.
