Software Engineer (Rust/C++/C/C#/Go) - CDI - Paris

🔥 Why Stockly needs you

Stockly is not a typical SaaS product. We operate a highly technical, backend-driven platform (~90% of the product’s value) where:

• Latency directly impacts revenue
• Correctness is critical
• Failure handling is part of everyday engineering

As a Backend Software Engineer, you’ll work at the very core of our platform:

• Real-time inventory synchronisation
• Order orchestration across multiple merchants
• Distributed systems under strong consistency constraints
• Integrations with complex external systems (ERP, OMS, WMS, marketplaces)

This role is for engineers who:

• Enjoy real-world complexity
• Want end-to-end ownership
• Care about robustness, scalability, and business impact

Your Responsibilities
You will:

• Design, build, and operate core backend services for:
  • Real-time inventory sharing
  • Order routing

• Integrate with external systems (ERP, OMS, WMS, marketplaces), handling:
  • Heterogeneous data models
  • Partial failures
  • Operational constraints
• Collaborate closely with Product & Operations to turn business problems into reliable technical solutions
• Improve reliability, performance, and architecture, contributing to:
  • Incident analysis
  • Technical standards
  • Long-term platform roadmap

🤝 Who you’ll work with

• A strong, product-oriented engineering team
• Experienced founders and senior engineers who have already scaled complex systems
• Daily collaboration with Product and Operations to ensure what we build actually works in production

✅ This is a deep engineering role, close to production and real business impact

🌟 Why this role is exciting

• Backend engineering truly matters at Stockly
• Few roles offer such a direct link between code and revenue
• You’ll solve problems with no obvious solutions, under real constraints
• Every improvement helps independent retailers compete with e-commerce giants
• If you enjoy building systems that must be correct, resilient, and scalable, this role is for you.
