Company mission
To back those who find themselves on a different path, either by choice or by circumstance, helping the exceptions to the rules that others aren’t interested in serving.
Role
Who you are
- 7+ years of product management experience, ideally in high-growth environments like SaaS, marketplaces, or DTC/eCommerce
- Proven track record of building and scaling growth products or platforms from the ground up
- Experience with A/B testing at scale, experimentation frameworks, and understanding of statistical principles
- Comfort working with AI or data science-powered products, or a strong interest in developing this skill set
- Strong understanding of growth channels (e.g. SEO, performance marketing, CRM) and how product can enhance them
- Ability to set strategic direction while also sweating the details
- Bonus points if you’ve worked in an early-stage environment, led cross-functional pods, or launched new business lines
- Think like a founder: you’re resourceful, strategic, and not afraid to go from zero to one
- Are deeply curious and energised by experimentation, learning, and shipping fast
- Get excited by technology—especially new capabilities like AI—and enjoy applying them creatively
- Communicate clearly and influence effectively across technical and non-technical audiences
- Love using data to make decisions and enjoy solving ambiguous problems through first-principles thinking
- Have a strong sense of ownership, but you’re also a true team player
What the job involves
- We’re looking for a Principal Product Manager to join the Growth team, leading our most ambitious growth initiatives. You’ll play a key role in shaping our strategy for acquiring new customers, building new growth products from scratch, and scaling our experimentation and marketing technology capabilities. This is a unique opportunity to blend long-term innovation with near-term impact, helping Marshmallow reach its next stage of growth
- Define and own a forward-looking growth product strategy, identifying bold opportunities to accelerate new business
- Lead the discovery, definition, and execution of new growth products and features, working closely with design, engineering, data science, and marketing
- Build and scale a culture of experimentation, leading the design of a robust A/B testing and measurement framework
- Explore and apply emerging technologies—including AI and personalisation models—to unlock new acquisition channels and improve user journeys
- Act as a leader for Growth across the business, setting vision and influencing at the exec level
- Partner with Growth Marketing to supercharge performance across SEO, referrals, affiliates, paid media, and organic channels
- Shape our Martech and content infrastructure to better support experimentation and real-time optimisation
- Own high-impact KPIs and clearly communicate trade-offs, priorities, and performance to the broader business
- Mentor other product managers and contribute to a strong product culture within the Growth team
Application process
- We break it up into 4 stages:
- Initial call with a member of our Talent Acquisition team (30 mins)
- A past-experience interview (90 mins) and metrics interview with Stephen Hemmings the Hiring Manager for the role
- An onsite Product Challenge interview for 2 hours
- A culture interview to check that your work style fits our processes and values (60 mins)
- We’ll let you know if you’re invited to an interview or not. But, as a small team with a lot of applications to consider, we can’t give individual feedback on each application
Salary benchmarks
Our take
For many ordinary people, insurance can be inaccessibly expensive. Marshmallow solves this problem by using data and technology to offer fairer coverage for car and van owners.
Car insurers generally quote drivers according to population data, and many drivers are overcharged due to age and demographics. By leveraging data and proprietary technology, Marshmallow can offer more accurate and personalised quotes delivered in minutes, meaning lower fees for drivers. Naturally, this approach has proven popular, with Marshmallow garnering impressive reviews and accolades since it first launched.
The insurtech space is becoming increasingly competitive, and more and more tech companies are moving into the car insurance space, so the company is currently looking to expand into other insurance areas as it grows into a multiproduct scale-up fintech company. Marshmallow’s unicorn status and doubling of profit since 2023 are clear indicators of the company’s ongoing success and scalability, and will help to facilitate this diversification.
For now, the company is focused on helping those outside the norm, such as those who have uprooted their lives and moved to the UK. But in the future, it hopes to expand to any group of people who are unfairly marginalised and whose problems Marshmallow is uniquely positioned to solve.
