Job description

Senior Data Scientist

Location: London, Greater London, UK, EC2V 8

Company: Apply4U

Job Description: We are working with Fyxer AI, the UK's fastest-growing tech company, to hire a Senior Data Scientist. Fyxer is building the Cursor for email. Since launching in May 2024, they have gone from $0 to $20m in ARR and raised a $30m Series B from top investors. Hiring small numbers of exceptional people, Fyxer's next vital hire is a Senior Data Scientist who will take on ownership of key predictive modelling.

As Fyxer's Senior Data Scientist, you will not only own the company's data science and analytics capabilities - you'll set the roadmap for high-impact business areas like marketing and retention, implement scalable solutions, and ensure stakeholders use data to make confident commercial decisions. You'll join a team of 2 Analytics Engineers and a Data Engineer, and will collaborate with the wider engineering team composed of Growth Engineering, Product Engineering, and Product Reliability Engineering.

One example of an immediate priority for the Senior Data Scientist is developing a Churn Prediction Model. There is a huge base of self-serve users generating rich product usage data, and the goal is to identify key churn signals and build a predictive model to surface actionable insights for Sales and Customer Success teams, through a production-ready model or API endpoint that can be easily consumed. This is a full-time position working in the Holborn, London office, 4+ days per week.

Primary Responsibilities

• Build and refine predictive models on multi-channel customer and usage data to drive product and marketing decisions
• Collaborate with engineering, marketing, sales, and product teams to define KPIs, experiment with new algorithms, and surface actionable insights that drive impact
• Maintain data infrastructure (BigQuery, dbt, Fivetran) and ensure data quality for reporting and self-service analytics
• Develop a culture of data-driven decision-making and proactively suggest improvements to tools, processes, and architecture

Requirements

• Exceptional SQL skills and comfortable with Python/R, with considerable experience building and deploying machine-learning models
• An experienced problem solver with a head for building solutions that have real business impact
• Experience working at a fast-paced early-stage tech company (Have demonstrable experience in transforming messy data into production-ready datasets and can communicate technical findings to non-technical stakeholders)

And ideally you...

• You want to build and have an impact from the ground up
• You want to have unreasonable ownership of your own world
• You work hard, with intensity every day & move incredibly quickly
• You always challenge the systems you're in to be better

Tech Stack

• BigQuery
• GCP
