Senior Backend Engineer, Growth Platform
Not your everyday company

Lemonade completely reinvented how insurance works. As a customer-centric tech company, we created an insurance experience that is smart, instant, and delightful.

At Lemonade, you'll be working with a group of like-minded makers, who get a kick out of moving fast and delivering great products. We surround ourselves with some of the smartest, most motivated, creative people who are filled with positive energy and good karma.

Unlike most publicly traded companies, we're nimble and efficient. We take pride in the fact that we still think and operate like a startup. We don't care much about titles and hierarchy and instead focus on innovation, bold moves, and challenging the status quo.

We're built as a lean, data-driven organization that relies on a common understanding of objectives and goals to provide teams with autonomy and ownership. We don't like spending our days in meetings and we skip committees altogether. At Lemonade, there's no such thing as going over someone's head. We have zero tolerance for bureaucracy, office politics, and lean-back personalities.

As a Public Benefit Corporation and a certified B-Corp, we deliver environmental and social impact using our products and tech. Through our Giveback program, we partner with organizations such as the ACLU, New Story, The Humane Society, Malala Fund, American Red Cross, 360.org, charity: water, and dozens of others, and have donated millions towards reforestation, education, animal rights, LGBTQ+ causes, access to water, and more.

What you're applying for

Lemonade transformed insurance by replacing legacy processes with automation and machine learning. On the Growth Platform team, you will architect and build a brand-new growth engine: an event-driven platform that ingests customer signals from across our ecosystem to power intelligent decision-making across all customer touchpoints.

You'll have full architectural ownership of the services and data pipelines that evaluate user context, trigger outreach, and directly influence company growth.

We believe three things matter for every role at Lemonade: drive to push through challenges, efficiency that keeps standards high while moving fast, and adaptability that lets you pivot with data and AI insights. These aren't buzzwords, they're how we actually work.

Our AI-first approach isn't just a tagline either. We're building the future of insurance with AI at the center, and we need people who are genuinely excited to learn and grow alongside these tools.

In this role you'll
  • Architect, build, and scale backend services that ingest and unify customer data from multiple sources into actionable signals for personalization, recommendations, and lifecycle journeys.
  • Design the decision engines and business logic that orchestrate outreach across communication channels, integrating experimentation frameworks and machine learning models.
  • Partner with product, data, and machine learning colleagues to turn customer insight into features people actually use.
  • Own your services end to end, from code quality and performance to reliability after launch.
  • Spot gaps in how we serve customers and drive the fix yourself.
  • Drive engineering excellence - Mentor engineers and help shape the engineering roadmap of the team as the team grows.

What you'll need
  • 7+ years building production backend systems that run at scale.
  • A track record of taking a problem from definition to a shipped, running solution with little day-to-day direction.
  • Hands-on experience with at least one modern backend language, plus proof you pick up new stacks and tools quickly.
  • A product mindset: you can explain why your work matters to customers and to the business.
  • A BSc in Computer Science, Mathematics, or equivalent experience.
  • Ready to work in an office environment most days of the week
  • Bonus points for
    • TypeScript and NestJS, customer lifecycle or CRM data, recommendation systems or experimentation platforms, or open-source contributions.
    • Experience with customer lifecycle systems, customer data platforms (CDP), or dynamic experimentation frameworks.
    • Experience integrating machine learning model outputs or predictive scores into backend workflows.
    • Active contributions to open-source software.
