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

💻 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.

🏡 Belonging at Bloom & Wild Group

We know that we learn through our differences, and building a diverse team has always been central to creating the best experience for our customers. We value all backgrounds, perspectives, ideas and experiences, and encourage everyone to share their opinions openly within our caring and inclusive team.

🧭 Our ways of working

We do things a little bit differently. From inventing letterbox flowers to founding The Thoughtful Marketing Movement. We’re big on collaboration, empathy, knowledge sharing and growth, and our values drive our priorities every day:

Lead change for good: we have the guts to try new things and step up to do what matters most

Think deeply, act swiftly: we make sure there’s thoughtful rationale behind our approach and always act swiftly to implement ideas

Care wildly: we pour care and creativity into everything we do and pay attention to the things that make a difference

Stay open, be curious: we’re open about what we’re doing and why, and we welcome challenges from each other

We really believe in the power of face-to-face connections - be that through a shared project, a learning and development opportunity, or an after work social - and trust our teams to make the right decisions (for them and us) about where and how they work each day. Our working patterns are flexible and vary across the business, depending on the type of work, need for collaboration, and personal and wellbeing circumstances.

🌟 (Some of) The good stuff

To care wildly for our customers, firstly we care wildly for our teams. We work hard to craft a culture of thoughtfulness and care, where there is a strong sense of inclusion and belonging, enabling all of our people to thrive and be successful each day.
