Senior Product Manager (Growth)

About Marshmallow

We build financial products that accelerate the economic freedom for people who move across borders. We started with car insurance - insuring over a million drivers - and we're scaling beyond. Tens of millions of people move countries each year, facing overlooked financial challenges. Our future is in building financial products around their needs to positively impact their lives.

How we work

We're really proud of the culture we've created. We push for progress every day, because we know that we'll only hit big milestones by taking lots of smaller steps. We're always open to helping our teammates, sharing our ideas, experience and knowledge to solve problems together. We take risks, think creatively and experiment relentlessly to meet our customer's needs, and never pass blame when things go wrong. We encourage people at all levels to take ownership of their work, and to be bold in challenging how we do things. Everyone has a voice and the opportunity to make an impact.

And autonomy and ownership are only possible with clear direction. That's why we collaborate to do in-depth planning twice a year, and make sure we leave with clear goals and objectives that flow from top to bottom. To ensure alignment across functions, most of our work is organized into three tribes: Acquisition, Retention & Claims. Each tribe has multiple teams working cross-functionally to do great work.

We're excited for the challenges ahead, and we need more people to help us tackle them! If life at Marshmallow sounds appealing, explore our Culture Handbook to learn more.

About the Role

We're seeking a Senior Product Manager to join our Growth team, one of the most ambitious squads at Marshmallow.

You will work on scaling our core Car Insurance product and unlocking growth for new multi-product launches. This role is ideal for someone who thrives on experimentation, understands how to drive growth across acquisition, conversion, and monetization, and is eager to make a significant impact.

You will have the opportunity to work across the entire growth stack, from optimizing landing pages and signup flows to exploring new channels, tactics, and customer segments. You will also help shape the foundation of our future products as we expand beyond car insurance.

What You'll Be Doing

• Own the strategy and roadmap for growth initiatives across core and new products.
• Identify high-leverage opportunities through data, user insights, and experimentation.
• Collaborate cross-functionally with marketing, design, data science, engineering, and operations.
• Launch and scale new products or growth loops with a clear commercial focus.
• Use rigorous experimentation and iteration to validate ideas and drive outcomes.
• Influence company direction by turning ambiguous problems into actionable strategies.

About You

You'll thrive if you're:

• Entrepreneurial and customer-obsessed — seeking untapped opportunities, moving fast to test them, and knowing when to pivot or scale.
• Ambitious and relentless — eager to build something big and committed to quality.
• Structured and strategic — able to focus on details while connecting work to company goals.
• Confident in ambiguity — capable of bringing clarity to complex situations.

We'd Love to Hear From You If You Have:

• 6+ years of product management experience in consumer or SaaS environments.
• A proven track record of shipping and scaling high-growth products.
• Experience owning end-to-end experimentation, including building funnels, running A/B tests, and iterating based on results.
• Data fluency — defining metrics, hypothesizing, analyzing impact, and modeling growth.
• Experience working cross-functionally in fast-paced product teams.
• Bonus: experience in insurance, fintech, or regulated environments.
