We are deeply invested in engineering excellence, platform reliability, and developer productivity.

What youll do:

• Design and deliver high-quality backend services Own end-to-end design and implementation of complex Java microservices powering item catalog ingestion, validation, transformation, and offer publishing workflows ensuring high throughput, low latency, and reliability across global markets.
• Contribute to backend architecture and engineering standards Actively participate in architectural discussions, propose and document technical solutions via ADRs, and help establish coding standards, reusable patterns, and service design best practices that elevate quality across the team.
• Champion reliability, observability, and testing Drive adoption of SRE best practices (SLOs, error budgets, alerting), build robust automated test coverage (unit, integration, contract), and proactively identify and resolve performance bottlenecks and systemic reliability gaps in production.
• Mentor and support engineering growth Guide and coach junior and mid-level engineers through code reviews, pair programming sessions, and design discussions; foster a collaborative team culture grounded in technical excellence and continuous improvement.
• Collaborate across functions to ship business outcomes Partner effectively with Product Management, Data Engineering, Frontend Engineering, and global market stakeholders to deliver well-crafted, maintainable backend solutions that directly drive marketplace growth.

• Strong Java and distributed systems expertise 10+ years of software engineering experience with deep proficiency in Java (8/ 11/ 17+), Spring Boot, microservices architecture, REST and gRPC APIs, and high-scale distributed systems design patterns.
• Event-driven and streaming systems experience Hands-on experience building production systems with Apache Kafka or equivalent event streaming platforms; solid understanding of eventual consistency, idempotency, and at-least-once/exactly-once processing semantics.
• Cloud-native and Azure platform experience Experience deploying and operating services on Kubernetes-based platforms (WCNP/Azure AKS or equivalent); working knowledge of Azure Cosmos DB, Azure Service Bus, and Azure Monitor; familiarity with CI/CD pipelines (Looper/Concord) and observability tooling (metrics, logging, distributed tracing).
• E-commerce or catalog platform domain knowledge Experience in item/product catalog management, marketplace platforms, or supply chain data systems is strongly preferred; ability to ramp quickly on complex business domains and translate requirements into clean, maintainable technical solutions.
• Team-level technical leadership Demonstrated ability to own services and features end-to-end, contribute meaningfully to technical design discussions, produce clear technical documentation, and mentor peers with a track record of raising the engineering bar within a team.
