Job description

Hi, we’re Bloom & Wild. We don’t just send flowers. We help our customers to care wildly. Caring wildly is celebrating the little things we all do for each other every day. Not just the big occasions. It’s being there for the highs. Stepping up for the lows. We care wildly about people and our planet. Which is why we’re so proud to be a certified B Corp™ – committed to making long‑term positive change for our community, and the world around us. Founded in 2013, our mission back then was to make sending and receiving flowers the joy that it should be, by harnessing technology, brand and letterbox delivery. We announced £75 million Series D funding in 2021 and that same year acquired bloomon in the Netherlands and Bergamotte in France. Together, we’ve fulfilled and delivered over 20 million orders (and counting!), making us the largest direct‑to‑consumer flower business in Europe. Now home to a family of 3 beautiful brands, we’re driven by our vision to create the destination for making life a little more thoughtful and beautiful. And we won’t stop at flowers and plants. Starting with the Bloom & Wild brand, we’re expanding our gifting offering to other categories like cakes, candles and cocktails. This is all part of our ambition to build Europe’s #1 direct‑to‑consumer gifting destination.

⚙️Data Science at Bloom & Wild

You will be joining a small data science team, currently consisting of 3 data scientists within an overall Bloom & Wild team of over 350 people and growing! We are a small, driven team that are set on expanding usage of data science across Bloom & Wild. We collaborate closely with the data engineering and product teams, the rest of the technology team, a separate business intelligence and analytics team, our CRM and operations teams to help us identify areas of opportunities and bring our projects to life. With millions of customers and hundreds of thousands of monthly transactions, we have a large and growing dataset that we use for training machine learning models. We have a number of models in production, from recommendation to forecasting engines, and a backlog of ideas to brainstorm, prototype and test. In terms of technologies: Python, Snowflake, dbt, git, ECS, Lambdas and Airflow on AWS are part of our day to day. We welcome applications from candidates based within roughly two hours of the UK time zone, covering many European countries. This helps us stay aligned as a team while supporting flexible, remote‑friendly ways of working. At Bloom & Wild, squads meet in person at least once per quarter in order to maintain connections, collaborate on larger projects and have fun together.

Most of our team is based in the UK or the Netherlands and works in a flexible model, with choice in how often they travel to the office. Our squads meet in person at least once per quarter in order to maintain connections, collaborate on larger projects and have fun together. We welcome applications from candidates based remotely within roughly two hours of the UK time zone, covering many European countries. This helps us stay aligned as a team while supporting flexible, remote‑friendly ways of working. You can read lots more about our technology stack and our culture over on our tech blog Code & Wild and on our technology careers page.

🚨Please note

We’re excited to open applications for this role ahead of the new year. While you’re welcome to submit your application now, we want to be transparent that our recruitment process will begin in early January. As a people‑first business, we also want to recognise that this may mean a short delay before you hear from us. Thank you for your patience and understanding—your application genuinely matters to us, and we look forward to reconnecting in the new year.

💻 What You’ll Be Doing

On a typical day for the data science team, we sync in the morning during stand‑ups to discuss the on‑going work and identify blockers or areas of collaboration. During the day, we will be brainstorming and prototyping models to solve specific business problems. Or, we will be writing robust, well‑tested code for new model deployments or supporting the design of A/B tests. Or we can be collaborating with other teams to gain a better understanding of business domain, data or requirements.

Your responsibilities will include:

• Have a critical role in architecting, implementing, and maintaining production‑grade, low‑latency ML services for ranking models, recommendation algorithms, and forecasting methods
• Collaborate with data scientists, product managers and other teams to brainstorm best approaches for solving the problems at hand, be they product‑related or with our infrastructure
• Help design experimentations to test our ideas and assess improvements to our models
• Advise on data strategy to provide datasets for future data science projects
• Deliver ML models with agreed engineering standards to ensure that our capabilities are resilient, scalable and future‑proof
• Enhance our AWS‑native MLOps platform, and guarantee high availability and low‑latency inference for our models
• Bring energy and positivity to the role, looking for every opportunity to learn and craft the role around our values: care wildly; think deeply, act swiftly; stay open, be curious; lead change for good

✅ You’ll love this role if you… (What excites us)

• Have a solid foundation in traditional ML techniques and the model lifecycle, with the practical expertise to handle class imbalance, tune hyperparameters, and resolve common pitfalls like overfitting
• Have demonstrable experience designing, deploying, and monitoring ML services to solve customer and business problems
• Have strong programming skills in Python for delivering production‑ready, well‑structured and documented code
• Have experience with large datasets and are proficient with SQL, exposure to Snowflake and dbt is a plus
• Are curious about customer needs and take a pragmatic, data‑driven, and experimental approach to solving problems
• Thrive in collaborative environments and work effectively with a range of people and teams
• Bring a positive, optimistic mindset, overcoming setbacks and motivating those around you
• Are keen to learn and stay up‑to‑date with the latest technologies and value sharing your knowledge with your peers

It would be great if you also have…

• Experience working on an e‑commerce site or in a fast‑growing (preferably consumer‑facing) start‑up
• Experience working in a fully‑remote setting

These are some of the skills and experience we think will enable success in this role, but please don’t worry if you are missing some of these. We’re committed to building a team made up of different strengths, skills and experiences, so if you’re excited about our values, passionate about what you do and would like to join us in doing things more thoughtfully, we’d love to hear from you.
