Job description

Health can’t wait. Not for symptoms to get worse. Not for a six‑month appointment. Not for a system to catch up. But that’s exactly how healthcare works today. You wait, until you can’t. Alan exists to end the wait. Health is a universal right, and we believe this right can only become real when it’s coupled with prevention. We need to stop treating health as something we repair and start treating it as something we build, every day. It’s not solely a question of willpower. It’s the healthcare system itself that needs to work for everyone, in a sustainable way. So we are building the new standard in prevention insurance. Alan is the first company that integrates insurance, prevention, and care into a single, acclaimed user experience. We are on an incredible journey to build a global leading company, with a unique culture. We already partner with 40K+ companies of all sizes, serving more than 1M+ members, and have reached €800M+ in ARR. Prevention as the new norm. That’s what we’re building with our team of 800+ people. If it speaks to you: we’re hiring across France, Spain, Belgium, and Canada. And beyond.

Design and own our billing platform

At Alan, billing is a critical platform that powers all of our services across multiples countries. We turn complex rules, multi-country regulations, and high transaction volumes into scalable, reliable systems.

As a Software Engineer on this team, you will:

• Build the core billing engine: process thousands of transactions daily with precision and reliability.
• Design modular, reusable billing primitives and abstractions that scale across products and regions.
• Integrate with payment gateways, partner APIs, and internal systems.
• Automate billing schedules and workflows across multiple countries.
• Ensure system reliability, accuracy, and operational excellence.
• Collaborate with product, design, and operations to create a unified platform.

Why this role is special:

• Design Alan’s core financial systems and global expansion.
• Work on complex distributed systems powering thousands of transactions daily.
• Influence platform design, architecture, and future scalability.
• Be part of a team that values engineering craftsmanship and continuous improvement.
• Work in an environment where your ideas, designs, and decisions drive tangible outcomes.

Your playground

• Stack: Python/Flask, React, React Native, PostgreSQL.
• What you’ll do: ship scalable, reliable systems and build the backbone of Alan’s billing operations.
• Impact: your work directly unlocks new services, countries, and exciting deals. It then supports their reliable operation.

Who we’re looking for

• We are looking for software engineers of all experience levels, ideally with backend / full-stack experience.
• Passionate about navigating complex business logic and system dependencies.
• Experienced with scalable, resilient platform design.
• Well-versed in OOP languages (Python, Java, C#).
• Fluent in English (French is a plus but not required).
• Curious, self-starting, humble, collaborative, and eager to grow.

Perks & Benefits

• Fair rewards & equity packages.
• Flexible office & remote options.
• Top-tier equipment: MacBook Pro, monitor, noise-canceling headphones.
• Flexible vacation & hours.
• Comprehensive healthcare for you, children, and partners.
• Transport support and coaching for personal growth.
• Training budget for conferences, courses, books.
• Extended parental leave for all parents.
