The Role

We are looking for a highly skilled Platform Engineer with an expert-level background in Node.js and TypeScript to join our Platform Team. In this role, your "customers" are our internal developers. You won't just be running apps in the cloud; you will be building the tools, SDKs, and automation logic that make development at our organization seamless. From managing our IDP to crafting custom CLIs and automated code migrations with ts-morph, you will be the architect of our Developer Experience.

* Code Evolution: Leverage tools like ts-morph to perform large-scale code transformations and maintain high-quality standards across our repositories.
* Standards & Versioning: Implement and enforce Semantic Versioning (SemVer) and best practices for package management to ensure stability across our ecosystem.
* Monitoring & Observability: Run applications in the cloud with a focus on proactive monitoring, ensuring our platform services are resilient and performant.
* Mentorship: Act as a technical bridge, helping product teams leverage platform tools effectively and gathering feedback to continuously improve our stack.

What We're Looking For

* Educational Background: Bachelor's or Master's degree in Computer Science or a related engineering field. Strong problem-solving skills and ability to work independently and collaboratively.
* Experience: Proven experience of minimum 5 years as DevOps or fullstack web developer.

* Frontend Literacy: Strong understanding of React and modern build tools like Vite. Track record of building Single Page Applications.
* Cloud & DevOps: Proven experience running applications in Azure and managing automation within Azure DevOps. Strong expertise with Kubernetes, such as CRDs.
* Process Driven: Experience with automated testing, code reviews, and Agile methodologies.
* Communication: Excellent written and verbal communication skills.
* Language Skills: Proficiency in English is mandatory, combined with fluency in either French or another language.

Nice-to-Haves

* Experience: Experience in the banking, financial services, or FinTech sector. Experience in big companies.
* Automation Enthusiast: Experience with Renovate for automated dependency management.
* Developer Portals: Hands-on experience with Backstage or similar IDP frameworks.
* Codemods: Experience using ts-morph or similar AST-based tools for automated refactoring.
* CLI Development: You have a passion for building intuitive Command Line Interfaces that developers love to use.
