Description du poste

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.

Responsibilities

• 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 seamlessly with internal systems and external payment platforms.
• Automate workflows and billing schedules at scale for companies of all sizes.
• Ensure invoices are accurate, reliable, and easy to manage for internal and external users.
• Collaborate closely with product, design, and operations to maintain a unified, high-quality platform experience.

Why you’ll love this role

• Solve technically challenging problems in a mission‑critical, high‑scale platform.
• Shape the architecture of Alan’s core financial systems and long‑term product strategy.
• Impact millions of members and clients, powering hassle‑free experience.
• Join a team obsessed with craftsmanship, scalability, and operational excellence.
• Work in an environment where your ideas, designs, and decisions drive tangible outcomes.

Technical Stack

• 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.

Qualifications

• 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.

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.
