Senior Back-End Java Developer

About the Role

We are seeking a Senior Back-End Java Developer to help design, build, and scale a modern, microservices-based platform supporting a next-generation loan processing application. This role is heavily focused on backend service-layer engineering using modern Java and microservices architecture, with exposure to blockchain and smart contracts providing future growth optionality.

You will join a small, highly collaborative engineering pod and take full ownership of code quality, testing, and delivery within an Agile environment.

Key Responsibilities

  • Design, develop, and maintain scalable Java-based microservices using Spring Boot and related frameworks
  • Build and maintain RESTful APIs and gRPC services supporting internal and external system integrations
  • Collaborate closely with Product Owners, Technical Leads, and other Engineers within a pod-based Agile model
  • Ensure clean, modular, testable, and reusable backend code
  • Own testing responsibilities end-to-end, including :

Unit testing

  • Integration testing
  • Mutation testing
  • Collaboration with Product Owners on UAT
  • Participate in code reviews, CI / CD pipelines, and continuous improvement of engineering standards
  • Contribute to high-level technical design discussions and present solutions to stakeholders
  • Actively identify and remove blockers, support backlog refinement, and ensure continuous delivery
  • Foster a collaborative engineering culture through knowledge sharing and cross-pod communication
  • Leverage AI-assisted coding tools (e.g., Windsurf or similar) to improve development and test efficiency

    • Technical Requirements

    Primary Skills (Must-Have)

  • Strong expertise in modern Java (Core / Advanced Java, J2EE)
  • Proven experience with microservices architecture and backend service-layer engineering
  • API development experience (REST, HTTP; gRPC a plus)
  • Hands-on experience working in Agile development environments
  • Solid understanding of Git , CI / CD pipelines , and software delivery best practices

    • Preferred / Nice-to-Have

  • Exposure to blockchain or distributed ledger technologies
  • Smart contract experience (strongly preferred but not required)
  • Familiarity with NoSQL databases (MongoDB experience helpful but not mandatory)
  • Experience with Apache Kafka , JIRA , and JUnit
  • Familiarity with Ethereum, Hyperledger Besu, or other EVM-based platforms

    • Priority Order for This Role

  • Strong Java microservices experience
  • Smart contract / blockchain exposure (valued for mindset and development model)
  • Front-end skills (lowest priority)

    • Blockchain experience is not required to be deep or specialized. Smart contract experience provides future optionality as the platform evolves beyond the MVP. Candidates with both Java microservices and smart contract exposure will be prioritized.

    Team Structure & Environment

  • Engineers work in small, self-sufficient pods (no dedicated QA teams)
  • Pods include Engineers, Product Owners, and Technical Leads
  • Engineers own the full development lifecycle, including testing and quality
  • Strong emphasis on collaboration, communication, and in-office engagement
  • Teams are primarily based in New York , with collaboration across India, the UK, and Pittsburgh

    • Testing Expectations

  • No separate QA team - engineers test their own code
  • Candidates are expected to already understand :

    • The importance of unit and integration testing

  • How to leverage AI tools to assist with test generation
  • Testing frameworks, standards, and mutation testing practices will be covered during onboarding
