Lead Data Scientist (Brightflag)

The Opportunity

As an ambitious and talented Lead Data Scientist joining our growing team, you will have experience of building machine learning solutions to solve complex business problems, ideally within a SAAS product focused environment. You will be adept at working through the full development pipeline from exploratory analysis to production, and comfortable working in a fast-paced  environment, where agility and resourcefulness are essential. You will have the opportunity to work in a culture that values autonomy and encourages novel and creative solutions to problems - not just the same old model development process. 

You are a team player working within the data science team and in collaboration with the product and engineering teams to develop innovative analytical solutions. You’ll ship a product that delivers  the best value for our customers in line with a clear company strategy with data science innovation as a core pillar of the product. 

You will work in classical machine learning tasks (classification, regression) as well as innovative Generative Ai applications.

*This is an individual contributor role and does not involve people management.

What You Will Be Doing

• Own the model development process from initial exploratory analysis and proof of concept through to production. You will be the catalyst that starts and progresses the development process and work in collaboration with colleagues to bring this to deployment
• Develop classification, regression and clustering models as appropriate to solve business problems
• Apply generative models to generate text, reports and insights as part of exciting new product features
• Analyse natural language text to uncover insights and transform data
• Develop proof of concepts to business problems including research of novel machine learning techniques and libraries to solve business problems
• Work with engineering colleagues to deploy models and AI solutions to production

Skills & Experience

To be successful in the role, you need:

• 5+ Years developing machine learning models and solutions, ideally in a software product focused environment
