Senior Full-Stack Engineer (Java+React)

Multitude is hiring a Senior Full-Stack Engineer (Java + React) to help design and build its Loan Management System end to end, from Java/Spring services and Kafka integrations to the React interfaces used by partners and operations teams. We're looking for an experienced engineer with a strong background in lending technology and LMS/LOS implementations, who writes reliable production code and uses AI coding assistants thoughtfully as part of their daily work.

Responsibilities

• Together with Lead Engineer and Tech Lead, design and build the LMS end-to-end — Java/Spring backend services and React operations/partner UIs — on the latest technologies.
• Deliver production-grade code: pull-request reviews, high test coverage and production observability (Kibana, Elastic APM, Prometheus/Grafana).
• Work effectively with AI coding assistants — use them to accelerate implementation, review, refactoring, and documentation while remaining accountable for the correctness, security, and maintainability of everything that ships.
• Contribute to the spec-first workflow: read and refine feature specifications, break specs into JIRA stories, flag missing scope early.
• Own features across the stack — from Kafka event contracts and REST endpoints down to the React screens partner staff and Bhawana operators actually use.
• Go the extra mile: stay current on tooling and techniques (including AI tooling), share what you learn, and push technical improvements proactively.
  
  

Required Skills And Experience

• 5+ years building production systems in Java (17+) and the Spring ecosystem (Boot, REST, JPA/Data, Security, Integration). You know why @Transactional is more subtle than it looks, you have debugged classloader and GC issues in anger, and you can reason about JVM behaviour under load.
• 3+ years of hands-on React user interfaces — not prototypes, not admin screens generated from a template. You understand rendering, state, forms at scale, accessibility, and the cost of every dependency you add.
• Demonstrable fluency with AI coding assistants (e.g. GitHub Copilot, Claude, Cursor, Codex, or equivalent) as part of your daily workflow — able to prompt effectively, review AI output critically, and know when not to trust it.
• Clean-code habits: patterns/anti-patterns awareness, well-structured, testable, maintainable, documented code.
• Distributed-systems maturity — you reason about failure modes, retries, backoff, poison messages, and what happens when the network partitions during a disbursement. You've built and operated microservices in production and know when not to use them.
• Solid grasp of REST API design, integrations, refactoring, secure coding, APM and troubleshooting.
• understanding JIRA and able to write specifications there with Acceptance Criteria.
• Hands-on experience with asynchronous messaging (Kafka or other)
• Analytical and problem-solving skills — able to break down complex domain problems and communicate solutions clearly.
• 6+ years in lending technology or NBFC/bank ops-tech roles, with at least one LMS/LOS implementation done end to end (FinnOne, Pennant, Lentra, M2P, Finflux or similar - lender side or vendor side)
• Knows the RBI digital lending guidelines well enough to spec a KFS or an FLDG ledger without being handed the circular
• Strong team player, comfortable working independently, solid written and spoken English.
  
  

Nice to have

• Familiarity with microservice architecture, event sourcing, distributed systems, authentication (OAuth 2.0 / OIDC).
• Experience with multi-tenant SaaS or B2B2C platforms (partner isolation, tenant-scoped data access).
• Financial-services or lending-domain background (loans, EMI, disbursement, DPD, collections).
• Working knowledge of: Kafka, Docker, Kubernetes, Camunda BPM, Kotlin, Liquibase, Kibana, Elastic APM, MySQL, PostgreSQL, MongoDB, ElasticSearch, Prometheus, Grafana.
• Frontend depth: state management (Redux Toolkit / Zustand / React Query), component libraries, accessibility, i18n.
• Experience with spec-driven or contract-first development (OpenAPI, AsyncAPI, Avro).
• Comfort with Gitflow, SonarQube, Maven/Gradle, Swagger/OpenAPI, JIRA, GitHub)
