Job Overview 

Job Description — Node.js Developer 

Software Engineer (5–10 Years of Hands-on Experience in Node.js, TypeScript, Data Migration, and Messaging Systems such as Kafka, SQS, RabbitMQ, or similar)

Role Overview 

As a Node.js Developer, you will play a key role in the migration and redesign of several legacy Erlang programs, transforming them into modern backend APIs built with Node.js and TypeScript to serve frontend applications and downstream services. 

Your mission will focus on: 

·        Analyzing existing Erlang-based services exposing APIs and processing data stored in Riak. 

·        Redesigning and rewriting these services as scalable, well-structured APIs (REST and/or event-driven) in Node.js / TypeScript. 

·        Migrating data and access patterns from Riak to more standard AWS-managed databases such as RDS or DocumentDB, including data modeling and performance optimization. 

·        Ensuring backward compatibility where required, while improving reliability, maintainability, and observability. 

·        Building APIs optimized for frontend consumption, with clear contracts, performance constraints, and security best practices. 

You will work within a cloud-native AWS environment, combining synchronous APIs with asynchronous messaging to communicate with other services, using technologies such as Kafka, SQS, or RabbitMQ. 

This role is central to the modernization of the platform, reducing technical debt and enabling future scalability. 

Key Responsibilities 

 Analyze existing Erlang-based services (APIs, data flows, Riak usage) to understand business logic and technical constraints. 
Design and develop backend APIs for frontend consumption using Node.js and   (REST and/or BFF patterns). 
Lead the migration and refactoring of legacy Erlang programs into maintainable, well-tested Node.js services. 
Redesign data models and access patterns, and migrate data from Riak to AWS-managed databases such as RDS or DocumentDB. 
Implement asynchronous communication with other services using Kafka, SQS, or RabbitMQ, depending on use cases. 
Ensure API performance, reliability, and scalability in a cloud-native AWS environment. 
Implement security best practices (authentication, authorization, API contracts, rate limiting). 
Write and maintain unit, integration, and migration tests to guarantee functional parity and safe deployments. 
Improve observability (logging, metrics, tracing) and operational readiness. 
Actively contribute to architecture decisions, code reviews, and technical documentation. 
Participate in agile ceremonies and collaborate closely with frontend, product, and platform teams. 

Your Profile 

Master’s Degree in Computer Science (or equivalent). 
5-10 years of experience in backend development, with strong expertise in Node.js and TypeScript. 
Solid experience designing APIs for frontend applications (REST, BFF, contract-first approaches). 
Experience working on legacy system migration or large refactoring projects; knowledge of Erlang is a plus but not mandatory. 
Strong understanding of data modeling and database migration, ideally from NoSQL systems to RDS and/or DocumentDB. 
Hands-on experience with messaging systems (Kafka, SQS, RabbitMQ or similar). 
Good knowledge of AWS services and cloud-native architectures. 
Strong awareness of backend security concerns (OAuth, JWT, IAM, API security). 
Strong testing culture: unit, integration, and migration testing. 
Fluent in English (mandatory if working remotely or outside France); French is a plus. 
You are comfortable working in a transformation context, pragmatic, quality-driven, and enjoy collaborating in small, autonomous teams. 

Short Summary 

We’re contracting a Node.js / TypeScript Developer 

Join an agile team to lead the modernization of a backend platform: migrating legacy Erlang services and Riak databases to cloud-native APIs on AWS, built with Node.js and TypeScript. 

Your work will focus on backend APIs serving frontend applications, robust data models on RDS / DocumentDB, and event-driven communication with other services via Kafka, SQS, or RabbitMQ. 

Tech stack: Node.js, TypeScript, AWS, RDS / DocumentDB, Kafka / SQS / RabbitMQ - API-first, microservices, cloud-native.
