Fullstack Developer

We are looking for a Fullstack Engineer (SDE-2) to join our engineering team, working across a Java/Spring Boot backend and a React frontend. 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. A significant share of our code is authored with AI coding agents, and we expect engineers to use them well while remaining fully accountable for what ships.

Responsibilities:

• Develop, test and maintain scalable backend services using Java, Spring Boot, PostgreSQL, Redis and Kafka.
• Build and enhance React-based frontend applications with clean, reusable and performant code.
• Integrate frontend and backend through well-designed REST APIs.
• Participate in design discussions and contribute to system architecture decisions.
• Ensure applications meet performance, reliability and security standards, including for financial workflows.
• Deploy, monitor and optimise services on AWS cloud infrastructure.
• Contribute to ETL pipelines and data workflows where projects require it.
• Collaborate with product, design and customer-facing teams to deliver high-quality features.

Requirements:

• 3-5 years of professional software development experience.
• Strong experience with Java, Spring Boot and REST API design.
• Hands-on experience with PostgreSQL, Redis and Kafka in production systems.
• Proficiency with React.js and modern frontend practices.
• Solid understanding of data structures, algorithms and system design.
• Familiarity with AWS services (EC2 RDS, S3 Lambda) and with Git and CI/CD workflows.
• Clear written and verbal communication, and the ability to collaborate across teams.
• Working knowledge of LLM-powered workflows, RAG pipelines, OCR or agentic AI systems.
• Effective day-to-day use of AI coding agents as part of the development workflow.
• Exposure to high-scale environments and the evolutionary technical challenges they present.
• Understanding of distributed systems and their operational complexities.
• Experience with fintech, payments or enterprise SaaS products.
• A proactive approach to learning, and attention to operational quality as a product concern.
