👻 Score fantôme 29%

Ce que ça veut dire : la probabilité que cette offre reste ouverte sans recrutement actif.Comment le lire : 60 % ou plus, on pense que c'est une offre fantôme. Un score plus bas est moins inquiétant.Comment on la calcule : ancienneté, republications, postes ouverts vs taille de l'équipe, rapidité de clôture, et si le salaire est indiqué.À noter : une estimation à partir de données publiques, pas un jugement sur l'entreprise. De vraies offres peuvent avoir un score élevé, alors prenez-le comme un indice, pas comme un fait.

Description

• Legacy Modernisation: Read legacy code (PHP, Perl, or JavaScript), extract the business logic, and reimplement it correctly within a modern microservices architecture. • Reliability First: Ensure idempotency, data integrity, and graceful error handling across all services — "almost working" is never good enough. • Greenfield & Refactoring: Split your time between building new features from scratch and refactoring existing legacy modules into clean, maintainable code. • API Engineering: Design and consume external APIs with a deep understanding of webhooks, callbacks, and complex retry policies. • Agile Collaboration: Maintain clean and strong English communication to effectively collaborate with multiple stakeholders across departments working in agile sprints. • Product Thinking: Go beyond the "what" and "how" of the code — bring a product-focused mindset to understand the business logic and end-user impact of what you build. • Infrastructure Contribution: Contribute to CI/CD pipelines, Docker, or Kubernetes infrastructure where relevant. If you have a passion for infra, you are more than welcome to bring it. • Innovation: Propose and advocate for tools or technologies that can demonstrably improve our performance, security, or development speed.

🎯 Exigences

• Python Mastery: 5+ years of backend engineering experience with strong Python expertise. Deep AsyncIO proficiency — you must be comfortable building non-blocking, high-reliability microservices. • Framework Expertise: Production-grade experience with FastAPI (not just familiarity). • Databases: Experience with MySQL and/or PostgreSQL — query design, schema understanding, and migration strategies. • Testing Discipline: Experience writing unit and integration tests (pytest preferred). • API & Reliability Patterns: Expertise in designing and consuming external APIs with a deep understanding of webhooks, callbacks, and complex retry policies. • Ownership Mindset: Willingness to take full ownership of high-traffic, always-up applications and operate independently within an established architectural vision. • Confidence in Complex Systems: Comfortable in complex distributed environments where reliability is non-negotiable. • Clean & Intentional Code: We value deep engineering logic over AI-generated snippets. You must be able to explain the reasoning behind every line you ship. • Curiosity for Product: You care about the "why" behind a feature — how it works for the end-user and what it means for the business. • Strong English: Both written and verbal to collaborate effectively across multi-functional teams. • Nice to Have: Experience with PHP, Perl, or JavaScript — a strong bonus signal for legacy comprehension. • Kafka / Redis experience. • Docker / CI/CD / Kubernetes familiarity. • Financial industry exposure — fintech, payments, 3DS, Token Management Systems, or payment gateway integrations. • Track record of successfully migrating systems from one language or paradigm to another.
