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.

• 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.
