Design and own robust backend systems that power a high-traffic e-commerce platform. As a Senior Ruby Engineer, you'll build services focused on membership, catalog, checkout, and fulfillment—ensuring reliability, scalability, and performance across every layer.
What You’ll Do
- Architect and deploy backend services in Ruby, prioritizing clean design, maintainability, and system resilience.
- Ensure data consistency between internal systems and third parties using both push and pull synchronization models for products, inventory, orders, and fulfillment.
- Build and maintain APIs that support web, mobile, and external integrations with a focus on stability and extensibility.
- Take full ownership of services from concept through deployment, monitoring, and iteration.
- Collaborate with product, design, and data teams to shape features that enhance the customer journey.
- Drive best practices in testing, observability, and code quality across the engineering team.
- Mentor junior developers and contribute to the growth of a strong, collaborative engineering culture.
- Help define long-term technical direction, especially as the platform scales in complexity and traffic.
What We’re Looking For
- 8+ years of experience developing and scaling backend systems in production environments.
- Deep expertise in Ruby, including metaprogramming, method dispatch, eigenclasses, and idiomatic patterns.
- Proven ability to build complex applications without relying on Rails, and to choose between Rails features and custom Ruby solutions appropriately.
- Strong command of Rails internals, especially AREL, Sidekiq job management, and performance optimization.
- Extensive experience with PostgreSQL, including advanced querying, data modeling, and performance tuning.
- Familiarity with cloud platforms like AWS, containerization via Docker, and services such as ECS and CodeBuild.
- Solid grasp of system design, data structures, and algorithms.
- Experience in fast-moving, high-growth environments where initiative and product awareness are essential.
- A collaborative mindset with clear communication skills and a drive to build high-quality systems.
Nice to Have
- Background in e-commerce, marketplaces, or membership-driven platforms.
- Experience with event-driven architectures and message queues like Kafka or SQS.
- Worked directly with design or product teams in consumer-facing technology companies.
- Interest in fashion, luxury brands, or retail innovation.
