Senior Data Scientist

The Opportunity

 

As  an ambitious and talented Senior Data Scientist joining our growing team, you will have previous experience of deploying machine learning solutions to solve complex business problems, ideally within a product focused environment. You will be adept working in the full development pipeline from exploratory analysis to deployment, and comfortable working in a start-up 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 will work within the data science team and in collaboration with the product and engineering teams to develop innovative analytical solutions. You are a team player, willing to collaborate to understand what you’re solving for. 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 be focused on external and internal facing Data Science projects - product facing features to provide insight, value & automation for our customers and models that make our internal processes more efficient and robust.

 

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

 

What You Will Be Doing

• Own the full model development process from initial exploratory analysis and proof of concept through to deployment in production
• 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 into a format that is appropriate for machine learning models 
• Develop proof of concepts to business problems including research of novel machine learning techniques and libraries to solve business problems
• Deploy models in our cloud infrastructure and design and implement MlOps pipelines
• Deploy models to production in the Brightflag app, working with engineering and product teams 

Skills & Experience

To be successful in the role, you need:

• 5+ Years developing and deploying machine learning models and solutions, ideally in a software product focused environment
• Strong programming skills in Python
• Strong skills in NLP, foundational representations like TFIDF matrices and topic modelling as well familiarity with Word2vec, Transformers etc... Familiarity with Spacy a plus 
• Some familiarity with generative ai text based applications and frameworks, in particular applying generative ai models to product application development. Knowledge of frameworks such as langchain or llamaindex  may be useful but not essential. Similarly familiarity with patterns like RAG would be beneficial but not essential
• Application of classification techniques to multiclass and multi label classification. 
• Familiarity with base Python stack such as Numpy,SciPy, Sklearn and experience developing Neural Network models in Keras/Tensorflow/PyTorch. 
• Application of regression techniques to predict continuous outcomes. Some familiarity with Time Series forecasting is also a plus.
• Clustering and segmentation analysis is also beneficial, familiarity with core algorithms like KMeans, DbScan etc.. 
• Comfortable working with ambiguity in a fast-paced product environment
• A passion for building product-focused solutions that solve customer problems
• A track record of shipping product by working collaboratively with product and software engineering teams
• Ability to work autonomously

 

The following are a bonus!

• Experience deploying machine learning systems to the cloud is beneficial In particular experience working with AWS machine learning stack as well as some familiarity with CI/CD tools such as Jenkins/AWS Codebuild/Bitbucket pipelines
• Experience working with docker and containerised environments a plus ; also some bash scripting experience and linux shell knowledge is advantageous. Experience working in a shared code repository with version control using git
• Some experience of dashboard tools such as PowerBi/Qlik/Tableau a plus but not necessary
