We currently have a diverse global team of 600 employees representing more than 50 nationalities. Our values are Activism, Transparency, Dedication and Greatness and Collective.
Vestiaire Collective is looking for a Senior Software Engineer M/F/D to join the Offer Management team located in Paris.
About the role:
The Offer Management squad is at the heart of how buyers and sellers connect and make deals on Vestiaire Collective. We own and build the key features that power this interaction, including negotiation, messaging, and pricing strategies, ensuring a smooth, fair, and engaging experience for both sides.
As a Senior Backend Engineer, you will play a central role in evolving these core capabilities. You will work closely with engineers across platforms (Android, iOS, Web), as well as product and design, to craft services that are scalable, reliable and impactful.
This is a high-impact role where technical decisions directly influence the user experience and business outcomes.
What you will do
- Design and build scalable, high-performance backend services and APIs that handle tens of millions of requests daily.
- Drive architecture decisions by contributing to technical design sessions and delivering clean, maintainable, long-term solutions.
- Modernize the platform by leading the migration from our PHP monolith to Go-based microservices and defining bounded contexts.
- Collaborate cross-functionally with Product, Design, Data, and iOS/Android/Web engineers to deliver features that enhance user experience and personalization.
- Ensure system reliability by implementing strong observability practices, including monitoring, logging, and alerting, while addressing performance bottlenecks.
- Own the full delivery cycle, from technical design and implementation to deployment and production monitoring.
- Uphold high engineering standards through thoughtful code reviews, mentorship, and precise documentation.
- Continuously improve system performance, reliability, and the overall developer experience.
Who you are
- Technical expertise: Mastery in either PHP or Go, with at least 5 years of experience in your primary language. Deep expertise in one is essential; experience in both is a plus.
- Architectural vision: Strong understanding of microservices architecture, distributed systems principles, and scalable design patterns.
- Proven builder: Track record of building and maintaining production systems that handle significant traffic and large data volumes.
- System design and code quality: Skilled in designing scalable, maintainable systems and writing clean, well-tested, efficient code following best practices (SOLID, DDD, Hexagonal Architecture, etc.).
- Problem solver: Analytical mindset with meticulous attention to detail when debugging complex distributed systems.
- Product-minded engineer: Appreciation for how technical decisions impact user experience, and ability to translate business requirements into technical solutions.
- Strong collaborator: Excellent communicator, able to articulate technical concepts clearly, defend your proposals with evidence, and stay open to team input.
- Autonomous and accountable: You take full ownership of your code and architecture, from design to delivery, and drive initiatives with minimal supervision.
