You will build and own product features end-to-end, from design discussion through to deployment and monitoring on AWS in close collaboration with product and design. Our platform processes invoices, payments and reconciliation for large enterprises, so correctness and reliability matter as much as delivery speed.

maintain scalable backend services using Java, Spring Boot, PostgreSQL, Redis and Kafka.\nBuild and enhance React-based frontend applications with clean, reusable and performant code.\nIntegrate frontend and backend through well-designed REST APIs.\nParticipate in design discussions and contribute to system architecture decisions.\nEnsure applications meet performance, reliability and security standards, including for financial workflows.\nDeploy, monitor and optimise services on AWS cloud infrastructure.\nContribute to ETL pipelines and data workflows where projects require it.\nCollaborate with product, design and customer-facing teams to deliver high-quality features.\n\nRequirements: \n3-5 years of professional software development experience.\nStrong experience with Java, Spring Boot and REST API design.\nHands-on experience with PostgreSQL, Redis and Kafka in production systems.\nProficiency with React.js and modern frontend practices.\nSolid understanding of data structures, algorithms and system design.\nFamiliarity with AWS services (EC2 RDS, S3 Lambda) and with Git and CI/CD workflows.\nClear written and verbal communication, and the ability to collaborate across teams.\nWorking knowledge of LLM-powered workflows, RAG pipelines, OCR or agentic AI systems.\nEffective day-to-day use of AI coding agents as part of the development workflow.\nExposure to high-scale environments and the evolutionary technical challenges they present.\nUnderstanding of distributed systems and their operational complexities.\nExperience with
