Job Summary

This role will play a key part in driving the technical direction for our modern eCommerce platform, helping to shape system architecture, streamline distributed workflows, and lead the development of robust, enterprise-grade solutions.

You’ll work closely with engineering, product, and design teams to deliver highly responsive, secure, and maintainable applications. We’re seeking someone who can operate both strategically and hands-on — someone who enjoys rolling up their sleeves to solve hard problems, while also influencing long-term platform decisions.

Key Responsibilities

  • Lead the design and development of scalable full-stack applications using Java (Spring Boot) for the backend and React/Next.js with TypeScript on the frontend
  • Define system architecture patterns for distributed systems, ensuring resilience, scalability, and maintainability
  • Develop and optimize RESTful APIs, microservices, and integration with messaging systems like Kafka, Solace, or Azure Event Hub
  • Collaborate with product managers, UX designers, and other engineers to translate business requirements into robust technical solutions.
  • Champion best practices in code quality, CI/CD, testing, and performance optimization
  • Guide junior engineers and contribute to a culture of technical excellence and continuous improvement
  • Participate in architecture reviews, system design discussions, and capacity planning

Skill Requirements

  • Strong experience with Java, Spring Boot, and React / Next.js / TypeScript in production systems
  • Deep understanding of system design principles, distributed systems, microservices architecture, and cloud-native patterns
  • Experience integrating with event-driven architectures using Kafka, Solace, or similar
  • Strong knowledge of API security, identity management, and performance tuning
  • Exposure to relational (MySQL) and NoSQL (Couchbase, MongoDB, etc.) databases
  • Comfort working in Agile environments, collaborating across teams, and influencing stakeholders
  • Ability to balance hands-on development with architectural decision-making

Other Requirements

  • 6+ years of full stack development experience with emphasis on Java, Spring Boot, and React/Next.js
  • 2+ years designing distributed, event-driven systems
  • Hands-on experience working in cloud environments (Azure, AWS, or GCP)
    • Proficiency with microservices, REST APIs, message queues, and streaming technologies
    • Experience with Micro Frontends, Headless Commerce platforms, or API gateways
    • Proven experience building scalable, distributed applications in an enterprise environment.
    • Solid knowledge of databases, APIs, and modern development best practices.
    • Demonstrated ability to work in Agile teams and deliver high-quality software on time.
