Join Our Mission

Skip the queue. Shape the future. See real impact.

At QuantSpark, we’re transforming how data and AI serve society. We combine the analytical discipline of strategy consulting with the pace and ownership of a scale-up. That means you’ll work directly on the problems that matter most—whether combating economic crime, modernising government services, or accelerating commercial growth for FTSE 100 companies.

Here, you’ll compress 5–10 years of traditional career progression into 2–3 years. From day one, you’ll support and deliver end-to-end projects, access leadership directly (including the CEO), and build cross-industry expertise that usually takes a decade to gain.

We don’t just analyse—we build, own, and scale solutions that shape the organisations we work with and have meaningful societal impact.

• Private Equity & Financial Services: Value creation analytics, risk identification, and portfolio performance for global investment and wealth managers.

• Asset Management: Data-driven systems, risk automation, and alternative data for top asset managers.
• Public Sector: Fraud analytics, predictive maintenance, and supply chain solutions for multiple UK government departments.
• SaaS & Manufacturing: Data-powered transformation across startups and global manufacturers.

The Role

• Mentor junior colleagues and independently run critical workstreams.
• Collaborate with senior clients, powering business strategies with evidence.
• Help shape QuantSpark’s evolving methods and standards as we scale.

In your first three months, your immediate tasks will be to quickly up-skill on new tools, deliver effective client presentations and deliverables and embed yourself into the team. You’ll have a key role in contributing to our culture, whilst proactively shaping your development plan.
