Senior Frontend Engineer - New Products

Marshmallow; London; On-site; GBP 125,000 - 150,000; Full time

Job description

We’re building a huge technology company that helps make moving countries easier. To fulfill our global ambitions, we need extremely ambitious people.

We back those who step outside the norm—people who find themselves on a different path, either by choice or circumstance. The exceptions to the rules that others aren’t interested in serving. Those are the ones we want to back, in everything we do.

So far, we’ve helped over one million drivers get a fairer price on their car insurance, most of whom are UK newcomers. Now, we’re creating tech-first financial products for anyone moving to a new country—people whose problems we are uniquely positioned to solve.

At Marshmallow, we live and breathe our values. They define who we are, what we stand for, and how we work daily. Could this be you? Check out our open roles.

We think big and long-term, and are unafraid of solving problems in novel ways.

Great leadership is the bedrock of great companies. That’s why we invest heavily in development and measure all roles, regardless of level, against a set of key behaviours. This framework helps set expectations and supports your growth.

Our core values include:

1. We're future-obsessed: We know our long-term goals and provide an inspiring vision to achieve them. We anticipate market, regulation, and technology changes to stay ahead.
2. We raise the bar: We set high ambitions, work with the best people, and support them to reach their potential. We eliminate mediocrity quickly.
3. We're culture icons: We are committed to our culture, acting in line with our values and encouraging teammates to prioritize culture.
4. We get stuff done: We execute swiftly and to high standards, both within teams and across functions.
