Role Overview
We are looking for a Senior Full-Stack
Software Engineer to join the core team building a premium B2B SaaS platform for critical logistics and aeronautical transport. The platform serves clients in aerospace (AOG operations), luxury & haute couture, and high-tech industries across 30+ countries , with real-time shipment tracking, IoT integration, and AI-powered operational intelligence at its core. You will own features end-to-end, from domain modeling to React interface, in a TypeScript codebase that applies Clean Architecture, DDD, and CQRS with conviction.
Key Responsibilities
1. Backend Architecture & Domain Modeling
• Design and implement NestJS modules following Clean Architecture: domain, application, infrastructure, and presentation layers with explicit boundaries.
• Model bounded contexts from business conversations, aggregates, domain events, value objects, before touching the database schema.
• Implement CQRS patterns rigorously: commands mutate state, queries serve reads, neither leaks into the other.
• Build async workers, event handlers, and queue-based processing with BullMQ and Redis for critical logistics workflows.
2. AI Integration & Intelligence Features
• Integrate LLM APIs (Anthropic Claude, OpenAI) into operational workflows: shipment anomaly detection, intelligent routing suggestions, automated status synthesis.
• Design prompt pipelines and AI-assisted features that augment, not replace, operational decision-making.
• Build the infrastructure layer that connects AI outputs to domain events and real-time data streams.
3. Frontend & Real-Time Interfaces
• Build responsive, performant interfaces with [protected info] 14+ (App Router, React Server Components, SSR) and React.
• Develop real-time tracking dashboards and operational control towers using WebSocket and event streams, visibility at a glance for critical shipments across 30+ countries.
• Implement role-based access control and workflows for logistics operators,
account managers, and clients.
4. Data, APIs & IoT
• Design and optimize PostgreSQL schemas with Prisma; model read projections independently from write-side aggregates.
• Build clean REST APIs with explicit contracts and OpenAPI documentation.
• Integrate IoT data streams for real-time shipment geolocation and condition monitoring.
5. Quality & Collaboration
• Write unit tests on domain logic, integration tests on use-cases, E2E on critical paths.
• Document architectural decisions (ADRs), API contracts, and system design.
• Collaborate directly with French product teams in English, async-first, written communication is a core skill here.
