Product Lead – Cash and TreasuryJob Title

About Invest Engine

Invest Engine is everything the modern investor should need. Unbeatable value, market-leading automation, and built for easy, long-term investing. We’ve built a strong foundation, have over £3.5 billion invested, award-winning service, and a passionate team, now we’re ready to scale.

We are looking for a Product Lead with deep experience in cash savings and treasury products to lead the development of Invest Engine’s Cash ISA proposition.

Initially, the role will focus on launching and managing a Cash ISA delivered through a partner. Over time, the successful candidate will help define and build the capabilities needed to bring more of the treasury solution in-house.

This is a hands‑on product leadership role spanning proposition design, commercial strategy, pricing, partner management, go‑to‑market and ongoing product performance.

• Lead the product strategy, design and launch of a partner-delivered Cash ISA.

• Own the commercial and customer proposition, including interest‑rate strategy, pricing governance and margin management.

• Develop acquisition and retention strategies, with particular focus on introductory and bonus rates.

• Model and monitor customer behaviour before and after bonus‑rate expiry, including balance attrition, switching and retention.

• Define the go‑to‑market strategy across positioning, target segments, channels, launch mechanics and lifecycle communications.

• Manage the product relationship with banking and infrastructure partners, ensuring clear ownership of service, controls and customer outcomes.

• Establish the MI needed to manage balances, inflows, outflows, rate sensitivity, cost of funds, margin and customer cohorts.

• Work closely with Finance, Compliance, Operations, Marketing, Engineering and senior leadership.

• Shape the longer‑term roadmap towards an in‑house treasury capability, including operating model, technology, controls, liquidity and regulatory requirements.

• Significant product leadership experience in cash savings, Cash ISAs, deposits or treasury‑led consumer products.

• A strong track record of building and launching cash products, ideally through both partner‑led and in‑house models.

• Practical experience setting customer interest rates and balancing growth, retention, funding requirements, margin and fair value.

• Deep understanding of bonus‑rate propositions, including acquisition economics, expiry communications and post‑bonus customer drop‑off.

• Experience managing savings‑product go‑to‑market strategies and customer lifecycle performance.

• Strong commercial and analytical judgement, with the ability to turn customer and balance behaviour into clear product decisions.

• Understanding of the UK savings market, ISA rules, Consumer Duty and the regulatory considerations relevant to cash products.

• Comfortable operating across strategy and delivery in a fast‑moving, regulated environment.

• A compelling, compliant and commercially sustainable Cash ISA is launched through the selected partner.

• Interest‑rate and bonus‑rate decisions are supported by clear economics, governance and customer‑outcome analysis.

• Acquisition, retention and post‑bonus balance behaviour are understood and actively managed.

• Invest Engine has a credible roadmap for developing an in‑house treasury solution.

We’re a lean, fast‑moving team that values clarity, ownership, and transparency.
