## Job description

We're looking for a Senior Backend Engineer to help build the core systems that price insurance for millions of customers. You'll join our Pricing Team in Amsterdam, where complex analytics meets high-performance engineering. You'll work alongside actuaries to turn their insights into code that scales, from our homegrown domain-specific language to AI-powered research pipelines.

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 core rating services that calculate prices for products used by millions
    
-   Architect systems across TypeScript, Rust, and Python, each solving a different kind of problem
    
-   Build AI-powered research pipelines that help actuaries discover new pricing patterns
    
-   Create SDKs and code patterns that other teams can build on
    
-   Optimize performance-critical systems where milliseconds shape the customer experience
    
-   Partner with actuaries to turn complex mathematical models into scalable code
    
-   Lead technical decisions on architecture, interfaces, and design patterns
    

### What you'll need

-   10+ years of experience building backend systems
    
-   Deep experience with system design and architectural decision-making, beyond API development
    
-   Strong proficiency in one backend language (TypeScript, Rust, or Python) and the ability to pick up the others quickly
    
-   A track record of designing complex systems from scratch, including the interfaces and abstractions
    
-   Experience building performance-optimized systems where technical choices directly affect business outcomes
    
-   A degree in Computer Science, Engineering, or equivalent experience
    
-   Ready to work in an office environment most days of the week
    
-   Nice to have:
    
    -   Experience with ML and Data science pipelines.
        
    -   Experience with vectorization frameworks like JAX.
