About Us
Afori is completely changing the way of work in one of the world’s largest industries - insurance.
We're an AI-first company with a vision to enable the insurance industry to embrace an agentic world. Afori is an AI platform built specifically for insurance brokers, automating back-office work starting at the inbox and turning unstructured communication into structured, executable workflows. It lives where brokers already work, inside Outlook and WhatsApp, and in a dedicated Afori web app.
Our product is already live and in production with insurance brokers, and we've raised a 12x oversubscribed €4m seed round from General Catalyst (early investors in Airbnb, Stripe, Mistral) alongside high-profile angels. We are an experienced founder team with deep sector understanding, as well as deep understanding of how to scale a startup, having built Insurtech unicorn wefox (peak valuation of €4.5bn) before. You will get the opportunity to join a fast-scaling startup as one of the first employees and significantly shape the future of the company and the insurance industry.
Your Impact
As a Senior Backend Engineer, you'll build AI agents that feed our context layer. At Afori, we want to deeply understand our customers and the risks they're exposed to by extracting and synthesizing structured and unstructured data points from multiple channels. You'll design new methodologies for data extraction and context engineering so our agents can advise and serve our customers in the best possible way.
Key Responsibilities:
- System Architecture: Design, build, and maintain scalable backend systems for AI agent orchestration and real-time data processing.
- Build AI agents: Take full ownership in building new AI agents that take over backoffice work on behalf of the broker
- AI/ML Collaboration: Partner with AI/ML teams to deploy models into production (e.g., customer insights, task automation).
- Performance Optimization: Optimize APIs and microservices for speed, security, and simplicity (embracing our Simplicity value).
- Problem-Solving: Tackle complex challenges in data integration, workflow automation, and system reliability.
- Culture & Collaboration: Champion “radical candor” in code reviews and team discussions to elevate technical quality.
- Customer Alignment: Work business to ensure engineering efforts directly address customer pain points (Customer Centricity in action).
