About QuantSpark
--------------------

We’re a 50 person London\-based AI and data science consultancy. We’re small enough that the work you do here is visible, and ambitious enough that what we take on is among the most interesting work being done in our field — applying advanced data science, machine learning and applied AI to problems that genuinely move the needle for our clients and the people they serve.

Our portfolio spans commercial transformation for FTSE 100s and high\-growth companies, alongside long\-running work tackling societal challenges. Across sectors — financial services, manufacturing, retail, and public sector — we partner with organisations to apply analytics and AI to real business problems, creating impact that goes well beyond financial outcomes.

What we do
--------------

We deliver four core capabilities to our clients:

• AiRE (AI Rollout Engine): ongoing enablement and integration of AI tools into day\-to\-day business operations. We accelerate adoption, improve productivity, and ensure sustained value through effective iteration.


• QuantSpark Labs: short, focused engagements to explore business problems and rapidly develop data and AI prototypes. Learn quickly, prove business value early, and reduce delivery risk before making larger investments.


• QuantSpark Transform: consulting\-led transformation programmes focused on changing operating models through data, AI and software. We align strategy, operating model, and technology to improve decision\-making and long\-term performance.


• QuantSpark Forge: enterprise data and AI solutions, configured and embedded to address common transformation challenges quickly and effectively. We solve high\-value business problems by deploying tailored solutions, accelerating time to value.

As a Product Manager at QuantSpark, you’ll take ownership of consulting engagements with our clients, with a particular focus on product development for both greenfield and established products.

This is a hands\-on role that combines product management, client delivery, and business analysis. You’ll own the product roadmap, lead discovery and requirements work, manage stakeholder relationships, and drive delivery through cross\-functional teams. You’ll also prototype solutions directly using AI tools — a way of working that’s become genuinely native to how we operate, not just something we offer clients — and support clients through adoption and change management as products move into live use.

Our products span data, AI, and analytics capabilities across industries including financial services, manufacturing, retail, and public sector. The right candidate will be comfortable moving across this range, applying strong product instinct to shape solutions that work for clients over the long term.

What you’ll do
------------------

• Engagement and stakeholder management. Own the client relationship on your engagements. Manage expectations, communicate progress, and build trust with senior stakeholders both internally and externally.


• Product strategy and roadmapping. Define product vision and translate strategic goals into clear, prioritised roadmaps and development activities.


• Agile product management. Lead agile ceremonies, manage backlogs, define acceptance criteria, and keep delivery teams focused on the highest\-value work.


• Discovery and user research. Design and facilitate stakeholder interviews, client workshops, and discovery sessions to understand business problems, user needs, and requirements.


• Hands\-on prototyping. Build functional prototypes and run experiments using AI tools (Claude Code, Cursor, and others) to validate ideas and test assumptions before committing engineering resource.


• Business analysis. Translate complex business requirements into product specifications. Clarify and challenge assumptions with both clients and engineers to ensure the right problems are being solved.


• Project management. Manage concurrent workstreams, coordinate delivery across cross\-functional teams, and ensure projects are delivered on time and within scope.


• User enablement. Lead training, onboarding, and change management activities to drive user adoption, so clients can realise value from the products we deliver.

• Proven experience in product management, ideally within a consulting, agency, or supplier\-side environment


• Strong client\-facing skills with a track record of managing stakeholder relationships and building trust with senior audiences


• Experience owning a product roadmap and leading delivery through agile methodologies across cross\-functional teams (developers, data engineers, analysts, designers)


• Comfortable facilitating workshops, running stakeholder interviews, and translating what you hear into clear product requirements


• Hands\-on experience prototyping with AI tools, or a clear willingness to get stuck in from day one


• Strong commercial acumen — you understand how product decisions connect to business outcomes and can balance client needs with commercial considerations


• Excellent communication skills, with the ability to explain complex or technical topics clearly to a range of audiences


• Comfortable with ambiguity and able to operate with autonomy across a variable and evolving portfolio of work

• Basic proficiency with SQL or experience working with databases


• Experience leading ad\-hoc analysis to better understand client requirements or validate product assumptions


• A product or project management qualification


• Experience with change management frameworks or user adoption strategies

Challenging projects, with real impact. You’ll be embedded on engagements that put advanced AI and analytics to work where it matters most — high\-stakes commercial, operational, and societal challenges that demand technical excellence and good judgment in equal measure.

Growth that compounds. £6,000 a year for personal development, days ringfenced for learning, and managers whose job is to help you progress. Last our team undertook more than 30 training programmes, certifications and qualifications — from NVIDIA generative AI to Masters in Data Science — with the majority of the team taking part. Our career framework has clearly defined progression at every level.

Ownership over outcomes. We trust people to lead their work and shape how the business evolves. That trust is matched by equity — our EMI share scheme is available to everyone in the business, regardless of seniority — so when QuantSpark grows, we all share in what we’ve built.

A team you’ll want to be part of. Hybrid, grown\-up, and human. We hire for craft, curiosity and candour, and protect the flexibility — work\-from\-abroad, flexible hours, full Vitality cover, comprehensive mental health support — that lets people do their best work and live full lives outside it.
