Job description:

Responsibilities:

Design, and deliver highly scalable, fault-tolerant services and features across our microservices platform.
Take end-to-end technical ownership - from requirements through deployment, monitoring, and production support.
Lead technical design discussions and contribute meaningfully to architecture decisions, technology choices, and engineering standards.
Proactively identify and address technical debt - refactor and improve maintainability, performance, and reliability of the codebase.
Troubleshoot and resolve complex production issues with urgency and structured problem-solving.
Collaborate with Product, QA, and stakeholders to clarify requirements, surface risks early, and drive solutions to completion with minimal supervision.
Champion engineering best practices - testing, CI/CD, security, observability, and documentation.
Leverage AI developer tools (e.g., GitHub Copilot, Claude, Cursor) effectively to accelerate development and improve engineering output.
Perform other duties as assigned.

React – Experience building scalable, maintainable front-end applications; strong understanding of state management, performance optimization, and component architecture.
Good grasp of JVM-based language fundamentals (Java or Kotlin); able to read, reason about, and contribute to codebases beyond the primary stack when the need arises.
Microsoft Azure – solid working knowledge of Azure services with hands-on experience across one or more of the following: Azure Container Apps (ACA), App Services (Web Apps), Azure Service Bus, Managed PostgreSQL, Key Vault, Application Gateway, Virtual Networks (VNet) & Subnets, Private Endpoints, and Private DNS Zones; experience deploying and operating production workloads in Azure.
Databases (SQL Server & PostgreSQL) – expert-level experience with relational database design, complex query optimization, indexing strategies, and performance tuning.
RESTful API design – proven ability to design, build, version, and secure APIs at scale.
Strong understanding of microservices architecture, distributed systems, and integration patterns.
Containers (Docker) – strong hands-on experience; comfortable with containerized application design, networking, and deployment.
Experience with CI/CD pipelines (Azure DevOps, GitHub Actions, or equivalent).
Solid understanding of Agile / Scrum practices and the full software development lifecycle.
Demonstrated and effective use of AI-assisted development tools as part of everyday engineering workflow.

Nice-to-Have Skills

Experience with Kubernetes or Azure Container Apps for container orchestration.
Familiarity with event-driven architecture and message brokers (e.g., Azure Service Bus, RabbitMQ, Kafka).
Experience with observability tooling - logging, metrics, and distributed tracing (e.g., Application Insights, OpenTelemetry).
Background in e-commerce, marketplace, or transaction-heavy platform environments.
Experience with Test-Driven Development (TDD) and pair programming practices.
Ability to learn and adapt to newer patterns and technologies as the landscape evolves.
