Description du poste

? Hi there! We are Paperbox!

Paperbox is a market leader in delivering AI Agents for claims & policy admin, serving insurers and brokers.

Do you know the feeling of having to wait forever for your insurer to answer your email? That is what we are solving!

About Paperbox

We build AI agents for claims and policy administration, serving insurers, banks, brokers and expertise firms across Europe. Our agents tackle the biggest bottleneck in insurance operations: the mailroom. 100+ customers in and growing fast, we're working towards a future where nobody is put on hold.

Role

You’ll join our FDE Team as the person who takes our AI agents from "signed contract" to "live in production at a real insurer's mailroom" - and keeps them running well after that. You'll own a portfolio of 6–10+ enterprise accounts at different stages, combining deep technical work with real customer contact.

What you’ll actually do:

• Lead onboarding’s from kickoff to go-live; configure and tune our agents for each customer's workflows, document types and process flows
• Build Python integrations with customer back-office systems - REST/SOAP APIs, webhooks, custom legacy stacks
• Tune prompts, evaluate LLM output, and design agent flows for new use cases
• Lead architecture and security conversations with customer IT teams - SAML/SSO/mTLS, data flows, privacy controls
• Translate what you see in the field into concrete input for Engineering and Product - your portfolio is our product radar

Who you’ll work with

You’ll be part of a tight FDE team that shares accounts, reviews each other's work, and learns in the open. Onboarding is structured: you’ll ramp on real accounts with a clear owner alongside you, not get handed ten enterprise customers on day one. If you're earlier in your career, you'll have the support to grow into full ownership; if you're senior, you'll have the room to shape how we deliver.

What we look for

• Strong Python - you can ship production code independently
• Comfortable with LLMs and modern agent frameworks (e.g. LangChain, LangGraph, or equivalent) - prompt engineering, evaluation, tuning
• Experience setting up integrations - APIs, webhooks, platforms like Make or Zapier
• You genuinely enjoy customer work - kickoffs, working sessions, conversations with customer IT teams
• A self-directed operator - comfortable holding 6–10+ accounts in your head and planning your own delivery
• Fluent in Dutch - your customer portfolio is mainly Dutch-speaking. English is a given.

We’re open on seniority - junior, mid, or senior. What matters is that you can do the work, and want to do it well.

This is what we value

We work hard to create a company culture where each individual can thrive in a healthy way and where we truly excel as a team. We keep the following values close to our heart:

• Stronger together:, We deeply care about our customers, users and employees and we believe you can best take care of others if you focus on taking care of yourself too.
• Distributed ownership,: Taking up responsibilities is encouraged. We share and create opportunities for each other to grow.
• Build to scale,: Everything we do needs to be scalable. This mindset helps us create the impact needed to drive us forward.
• Quality, then speed:, We work intentionally towards a bigger picture that requires us to think before we act. Building a foundation for future success is setting yourself up to win.

Perks and benefits

At Paperbox we strongly believe in a diverse and healthy work environment. That’s why we spend a lot of time on providing perks and benefits that help you thrive as a person.

We offer:

• A flexible office culture, combining our amazing office space atWintercircuswith the freedom to work where you perform best
