Stack: Node.js (TypeScript), AWS (focus on AWS Lambda), Step Functions, MySQL, Docker, Microservices, Serverless, AI Agents.
We are seeking an experienced Senior Node.js Developer to join our team of talented developers for a stable yet dynamic enterprise product.
As a Node.js Developer, you will play an integral role in developing, maintaining, and refactoring the existing codebase of a multi-service product with complex business logic. You will work closely with our experienced Backend team, leverage the latest technology stack, and have clear opportunities to grow into a Team Lead role in the future.
About the Project
A stable enterprise product for creating marketing presentations, preparing accompanying materials, and developing sales cycle business assistants for global pharmaceutical companies (such as AstraZeneca, Novartis, Pfizer, Veeva) and financial institutions (such as ING and Van Lanschot). We have been developing our own codebase since 2015.
Our services are distributed across multiple Availability Zones, adhering to a service-oriented architecture. Since 2018, we have prioritized GraphQL, although we maintain comprehensive support for RESTful APIs. Our core API services are built on a diverse stack of programming languages, each chosen to optimize task performance. This stack includes a rapidly evolving Golang Core API, legacy Core API services in PHP (leveraging frameworks like Laravel and Yii2) for established business logic and data layer interactions, Node.js (utilizing both JavaScript and TypeScript), Python APIs, and .NET Core C# components.
We utilize a hybrid cloud infrastructure, harnessing the strengths of both AWS and GCP to meet our operational needs, with a heavy focus on Serverless. Our work also involves extensive integration with API partners, including Veeva, Salesforce, and various others, to ensure a seamless and robust service ecosystem.
As a product with high-security requirements, we undergo regular penetration testing from auditors and client companies to ensure compliance with industry standards such as OWASP, SOC, and ISO.
