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…
