Mathematician

New Yesterday

Title: Principal/ Lead Mathematician
Rate: £450-£550 Outside IR35
Contract duration: 3 months (Initially)
Start date: January start date!
We're partnering with a highly technical, early-stage organisation building a next-generation, AI-driven decision platform. They're looking for a Principal / Lead Mathematician to own the mathematical foundation that underpins the entire system.
This is a rare opportunity to sit at the heart of product design - translating human problem-solving processes into rigorous mathematical, algorithmic and optimisation models that power summarisation, semantic search, and decision-support workflows.
You'll lead the design and validation of core algorithms, working closely with Data Scientists and Engineers to embed mathematically sound models into a modular, cloud-native platform.
What you'll be doing
Designing end-to-end mathematical models that translate real-world workflows into executable system logic
Applying algebraic modelling, graph theory, optimisation and statistics to complex, unstructured data problems
Prototyping and validating algorithms in Python and MATLAB
Shaping the mathematical backbone of vector search, intent extraction and LLM-driven workflows
Producing clear, auditable documentation in LaTeX and Jupyter
Acting as the mathematical authority across the platform and mentoring others where needed
What we're looking for
Strong background in applied mathematics, operations research or optimisation
Proven experience with graph-based models, algorithm design and probabilistic methods
Comfortable working alongside Data Science and Engineering teams
Ability to translate abstract, human-led processes into formal mathematical representations
Experience supporting AI / ML-driven systems (theoretical or applied)
This role suits someone who enjoys owning complex problems from first principles , shaping both the theory and its real-world application in a cutting-edge technical environment.
If you're interested in this role or know someone who would be, then please apply with an updated CV and reach out to a. methula@ioassociates. co.uk
