Senior Consultant at Chi Square Economics
Quantitative Researcher (Applied Modelling & Financial Analytics) - competitive salary -
Newcastle Upon Tyne, UK or Madrid, Spain
We’re working with a fast-growing, technically driven consultancy as it expands its quantitative research team in both Newcastle and Madrid. The firm partners with leading financial institutions on a broad range of projects — from pricing and risk analytics to trading tools and model development — offering the chance to apply advanced technical skills to high-impact, real-world problems.
This is an ideal opportunity for someone with a solid foundation in quantitative finance and programming, who is now looking to take on more responsibility and contribute to full-lifecycle development across both research and delivery.
You’ll be working in a team that designs, builds, and implements models and analytical tools used in derivatives pricing, trading, and risk management. The role combines technical depth with hands-on exposure to real financial products and market data.
Responsibilities:
* Developing and maintaining pricing, risk, and trading models across multiple asset classes
* Writing clean, production-quality code to support model deployment and tool development
* Using data and statistical methods to solve practical financial problems
* Collaborating with stakeholders across quant, dev, and client-facing teams
* Supporting and enhancing existing models and tools as market needs evolve
The ideal candidate will bring a combination of technical fluency, financial product knowledge, and a strong interest in solving complex challenges. You’ll be comfortable working independently on model development while also contributing as part of a collaborative and fast-paced team.
Key Qualifications
* Postgraduate degree (MSc or PhD) in a highly quantitative subject (e.g. Mathematics, Physics, Engineering) from a top-tier university
* Prior experience in financial services or fintech (e.g. investment bank, asset manager, hedge fund, or analytics provider)
* Working understanding of derivatives pricing, modelling, or risk analytics (e.g. in Rates, Equities, or structured products)
* Strong coding ability in one or more of: C#, C++, Python, Java
* Exposure to machine learning or advanced statistical methods is a plus
* Strong academic performance at A-Level (or equivalent)
Please note: applicants must have the right to work in the UK or Spain. Visa sponsorship is not available for this role.
* Competitive salary and benefits package
* Hands-on work in real financial markets with high visibility
* Fast-paced yet balanced working culture — with a focus on quality, not long hours
* Opportunities to learn from experienced quants, software engineers, and finance professionals
* Growth and progression potential in a business with long-term backing and ambitious plans
If you’re looking for a role that builds on your existing experience and challenges you with meaningful work in quantitative finance, this could be a fantastic next step in your career.
