- Be very experienced working with pull, push models for data parity between third parties and our systems around e-commerce concerns of product, stock, orders and fulfillment synchronization.
- You'll design, implement and deploy reliable software to solve complex e-commerce concerns.
Architect systems for membership access, catalog management, checkout, order fulfillment, and payments.
Collaborate cross-functionally with product, design, and data teams to deliver features that elevate the user experience.
Own backend services end-to-end, from design to deployment and monitoring.
Contribute to best practices in code quality, testing, reliability, and observability.
Help define our backend architecture and make strategic technical decisions as we scale.
Mentor junior engineers and foster a culture of technical excellence and collaboration.

Who You Are

8+ years of experience building and scaling backend systems in production environments.

Expert skills with Ruby idiomatic patterns, terse styling, metaprogramming and be able to create macros, DSLs, etc.
- Have experience contributing to wildly used gems or developed internal DSLs for domain specific needs.
Ruby without Rails - you are able to develop complex applications and deploy Rails features vs custom Ruby plugins for the right use cases.
Proficiency in building APIs and distributed services using Ruby.
Must know the full ins/outs of Rails AREL, performant code, and proper Sidekiq job handling.
Have expert knowledge of proper data model design for e-commerce concerns and understand how to handle locking sensitive resources such as a credit card charge and concepts such as state machines.
Expert experience with PostgreSQL, including complex joins and reporting queries, and familiarity with data modeling and performance optimization.
Familiarity with cloud infrastructure (e.g., AWS, ECS, CodeBuild) and containerization (Docker,).
Strong understanding of system design, data structures, and algorithmic principles.
Comfortable working in high-growth, early-stage environments—bias toward action and strong product sense are key.
A collaborative teammate who communicates clearly and is excited to shape the future of a luxury tech brand.

Bonus Points

Prior experience in e-commerce, marketplaces, or membership-based platforms.
Familiarity with event-driven architectures and message queues (Kafka, SQS, etc).
Experience working closely with design or product teams in consumer-facing companies.
Passion for fashion, luxury, or retail innovation.
