Experience

4–7 years of professional software engineering experience with strong ownership of production features and full-stack delivery, ideally within fintech or other regulated environments.

Role Overview We are hiring a Software Engineer to build and evolve core fintech applications across frontend, backend, APIs, and data layers. This role suits an engineer who can independently deliver complex features end-to-end, integrate third-party systems, apply sound engineering judgement, and begin influencing technical direction in a regulated environment.

Key Responsibilities

Full-Stack Delivery

• Design, build, and maintain end-to-end features across frontend, backend services, APIs, and databases.

• Develop backend services primarily using PHP/Laravel and Node.js (exposure to Python/FastAPI is a plus).

• Build maintainable, responsive UIs using a modern JavaScript framework such as Vue.js.

• Own features through design, development, testing, deployment, and iteration.

API, Backend & Integrations

• Design and implement REST APIs with proper domain modelling, validation, versioning, and error handling.

• Apply best practices for authentication and authorization (e.g. JWT), idempotency, and backward compatibility.

• Integrate complex third-party systems — payment gateways, KYC/e-Sign, banking rails (e.g. NACH), and platform APIs.

• Identify and address performance, scalability, and reliability concerns early.

Data & Persistence

• Design and work with relational data models using MySQL and PostgreSQL.

• Write efficient queries and manage schema evolution safely.

• Ensure data accuracy, integrity, and traceability appropriate for financial systems.

Cloud & DevOps

• Build and deploy cloud-native services on AWS (e.g. S3, ECS, SQS).

• Work with containerised workflows and CI/CD tooling (Docker, Jenkins, Git/Bitbucket).

Gen-AI & Engineering Productivity

• Use AI-assisted tools and agents for coding, code review, commits, and full git-flow automation.

• Validate AI outputs for correctness, security, and production readiness, with no sensitive data leakage.

• Exposure to spec driven development is a bonus

Quality & Collaboration

• Participate in code reviews and contribute to testing and production stability.

• Diagnose and resolve production issues with a focus on root-cause prevention.

• Collaborate closely with product, design, QA, and platform teams.

Required Skills

• Strong backend experience in PHP/Laravel and/or Node.js.

• Solid frontend experience with a modern JavaScript framework (Next.js React.js preferred).

• Strong REST API and RDBMS fundamentals (MySQL/PostgreSQL).

• Experience integrating third-party systems and building secure, scalable services.

• Hands-on experience with cloud (AWS) and CI/CD tooling.

• Awareness of fintech security, reliability, and compliance expectations.

Preferred / Bonus

• Python/FastAPI exposure.

• Experience with automated testing frameworks.

• Experience mentoring junior engineers.
