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 understating 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

We're looking for a Senior Backend Engineer to help build and scale the Machine Learning Platform that powers how Lemonade uses AI across the business. You'll be part of the ML Platform team, designing the infrastructure that lets our data scientists move faster, ship smarter, and operate with confidence in production.

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

• Design and build the foundational ML platform and AI agents to accelerate data science model delivery across all business units
• Architect cloud-native microservices running on Kubernetes, using infrastructure-as-code to automate model deployment and management
• Own the end-to-end ML lifecycle, covering training, testing, deployment, and real-time monitoring
• Evaluate and choose the right tools and technologies based on workload demands and performance requirements
• Collaborate with engineering, data science, and product teams to keep ML projects aligned with business goals
• Identify and fix reliability, scalability, and performance gaps before they become problems

What you'll need

• 6+ years of software engineering experience, with a strong record of delivering high-scale, production-grade systems
• Strong proficiency in Python
• Hands-on experience with relational and NoSQL databases, and at least one major cloud platform (AWS, Azure, or GCP)
• Experience with training, testing, deploying, and monitoring real-time or near real-time ML models in production
• Fluent with AI-powered development tools like Cursor and Claude Code, and genuinely curious about what's next in GenAI, LLMs, and AI agents
• Familiarity with AI concepts like RAG, embeddings, mixture-of-experts, prompt crafting, and LLM context engineering - an advantage
• Sharp problem-solving instincts and the ability to move fast without cutting corners
• Bachelor's or Master's degree in Computer Science, Engineering, Statistics, or a related field
• Ready to work in an office environment most days of the week
