Role Description 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. Qualifications - 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. Requirements - 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. Benefits - Opportunity to work on cutting-edge technologies. - Collaborative and agile work environment. - Professional development and growth opportunities. - Flexible working arrangements.

Role Description We’re looking for a senior engineer with strong data instincts. This role sits at the intersection of backend systems, data pipelines, and AI-powered workflows. You’ll have broad ownership to design and build systems that ingest, transform, and operationalize data—powering both user-facing features and internal intelligence systems. This is not a narrow “data engineer” role. You’ll work across the stack, but with a deep bias toward data modeling, pipelines, and system design. - Turn ambiguous product and operational workflows into well-structured systems combining data pipelines, backend services, and AI-driven logic - Design and build agentic AI systems that reason, take actions, and orchestrate multi-step workflows (not just simple LLM integrations) - Develop and operate production-grade data pipelines powering both user-facing features and internal systems - Build backend services primarily in TypeScript, with pragmatic use of Python where appropriate - Design APIs and system boundaries that enable modular, composable AI and data workflows - Partner with product and operations to translate real-world processes into AI-augmented, scalable systems - Use AI-assisted development as a default—from prototyping to debugging to system design - Improve reliability, observability, and performance across services - Own architectural decisions within your domain, balancing speed and long-term maintainability Qualifications - Proven experience owning and operating data-heavy systems in production - Strong experience with data pipelines (ETL/ELT, event-driven, or workflow-based systems) - Proficiency in TypeScript (primary language); other typed language experience is a plus - Generalist mindset with strong data modeling and system design instincts - Ability to go from zero → one → scale with minimal guidance - Experience in fintech, tax, or regulated environments a strong plus - Familiarity with security and compliance considerations (sensitive data, auditability, access controls) a strong plus Requirements - You actively use AI tools as a core part of your development workflow (not optional) - You believe the software engineer’s job is fundamentally changing—and you lean into that shift
