  • We are looking for an enthusiastic and pragmatic Senior Data Scientist to join Coefficient's Data Team full-time.

    You'll be working on projects with multiple clients across different industries, including clients in the UK public sector, financial services, healthcare, app startups and beyond. This is no ordinary data science role. Beyond coding, you will also be managing client projects, leading a client's data team, delivering Python workshops, and mentoring others.

    This is our first Senior Data Science role so you can expect to play a large role in shaping the company's future, working closely with the CEO to ensure that we continue to deliver a 10-star service for our clients as we grow. You'll be at the heart of delivering data science & engineering projects including hands-on coding and code reviews. For some clients you will be Coefficient's technical lead and project owner. We aim to be best-in-class at what we do, and we want to work with people who share that same attitude.

    This is an exciting time for Coefficient, and an excellent opportunity to work within a unique and fast-growing startup.


    About Us

    💼 Coefficient is a full-stack data consultancy offering end-to-end solutions in data scienceengineeringmachine learninganalytics, and other AI-related services, as well as bespoke training courses.

    🔧 We are driven by the challenge of solving real-world problems by combining statistical techniques with a lean start-up mentality and a technical skillset. Our service is end-to-end, whether it's delivering innovative solutions for a UK government agency or providing an in-house data team to a fast-growing tech company.

    🎓 We have designed and delivered data training courses for clients such as BNP ParibasEYHawk-Eye, the BBCACCA, and the Metropolitan Police. Our consulting work is highly multidisciplinary; in a single week we may be writing trading algorithms, routing delivery drivers, and predicting elections.

    👥 Our team is our greatest asset. We invest heavily in professional development through our "10% Time" programme. We work with highly intelligent and passionate people who take pride in their work and enjoy a high level of independence.

    What does the work look like?

    This is a role for curious people who love to learn and be challenged! On any given day, you might be doing one of the following:

    • Building a geospatial time series model blending bespoke & open data to forecast a client's future revenue.
    • Tuning a PyTorch deep learning algorithm for one-shot image classification.
    • Writing data migrations for a Django application that helps automate accounting workflows for an audit team.
    • Advising the CEO of a 100+ person company on how to build a modern data analytics and BI capability.
    • Mentoring and reviewing code written by Coefficient or our clients' staff.
    • Project management and leading agile meetings as technical lead for a client project.
    • Teaching an introductory "pandas 101" workshop to an online class featuring attendees from across the world.
    • Working with the CEO to craft project proposals to win future clients.


    Our ideal candidate would:

    • Have at least 5 years of experience working in data roles (e.g. data analytics, data science, data engineering).
    • Have consulting or contracting experience including writing project plans and quotes, and experience of managing client relationships & delivery expectations.
    • Have experience using tools such as Python for data analysis, data science, and/or machine learning.
    • Have used any libraries in the Python Open Data Science Stack (e.g. pandas, NumPy, matplotlib, Seaborn, scikit-learn).
    • Enjoy sharing their knowledge, experience, and passion with others.
    • Have the ability to build and maintain strong relationships with clients, for example by writing and presenting slide decks to showcase our work during sprint reviews and project showcases.
    • Demonstrate an ability to find innovative solutions for client problems through a combination of analytical skills, application of methodological best practices, and the technical experience to know which is the right tool for the job.
