Team: Engineering

Experience: 3 to 5 Years

Location: Mumbai - Andheri East

Reports to: Engineering Manager

Role Overview Joins the engineering team working across a Java/Spring Boot backend and a React frontend, building and owning product features end to end — from design discussion through to deployment and monitoring on AWS — in close collaboration with product and design.

The platform processes invoices, payments and reconciliation for large enterprises, so correctness and reliability matter as much as delivery speed. A significant share of the code is authored with AI coding agents, and engineers are expected to use them well while remaining fully accountable for what ships.

Key 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.

Qualifications

- 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.
- Explicit written and verbal communication, and the ability to collaborate across teams.

Preferred / General Requirements

- 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.
