Join a fast-growing tech company that's reimagining how modern marketplaces are built. We're looking for a hands-on Senior Backend Engineer to help evolve a highly scalable platform powered by microservices and a cutting-edge cloud stack.

What You’ll Do:

1. Design and build robust, scalable backend services within a service-oriented architecture.
2. Work closely with product, design, and fellow engineers to take features from concept to delivery.
3. Own your outcomes—write clean, reliable code that solves real-world problems.
4. Help shape engineering practices and mentor junior developers.
5. Collaborate with a remote-first, high-performing team across time zones.

Technologies involved include Kotlin, Java (or other JVM languages), Spring Boot, GCP, Kubernetes, Docker, Kafka, PostgreSQL, MongoDB, CI/CD pipelines. Experience in Go, Python, or C# is also welcomed.

What You Bring:

• 5+ years of backend experience in production environments.
• Comfort working in microservices and cloud-based architectures.
• A passion for writing quality code, learning, and improving team processes.
• Experience collaborating in distributed teams.

This is more than a coding job—it’s an opportunity to shape a platform, grow your career, and build tech that scales.
