Job summary

Groupe Faubourg is seeking an 8+ year senior software engineer to join the platform team as a core contributor. You will shape the workflow engine, authentication/authorization, data model, and API v1 using Vue/Nuxt and NestJS in a production-grade, multi-tenant environment.

You will drive architecture decisions, scale the stack, and implement multi-country patterns from day one. English is the working language and EU remote work is welcomed.

Qualifications

• 8+ years building software, with significant enterprise SaaS experience.
• Deep TypeScript / Node. Experience with state machines or workflow engines (Temporal, XState or equivalent) is a strong plus.
• Real multi-tenancy and authorisation experience — this is the first thing you will work on.
• Pragmatic architect: ships incrementally, documents decisions, keeps the bar high where most code is agent-generated.
• Already fluent with AI coding tools, or hungry to become so. This is how the team works.
• Comfortable with legacy, ambiguity and multi-country enterprise reality.
• English is the working language. Remote-friendly within the EU.

Responsibilities

• Build the platform core with the pod lead: workflow orchestration (approvals, SLA timers, multi-actor handoffs), API platform, data layer, integration framework.
• Own hard technical calls on your surfaces: architecture, stack evolution, scaling.
• Deliver the multi-tenancy and authorisation work that every client-facing module depends on.
• Design for multi-country from day one (UK, DE, FR, ES, BE/NL): country business rules, tax, compliance.
• Set the patterns the product pods copy: testing, observability, module conventions.
• Work AI-native: coding agents are part of the team; you define how their output is validated and industrialised.
