Hyderabad (On-site) | 4–6 years experience The Role:

We're looking for a Software Developer who is strong on the backend, plays well with a team, and isn't afraid to bring in better ways of doing things. You'll design, build, deploy, and operate the microservices that power our loan platform, behind our mobile app, web app, and internal control panels.

You'll own features end-to-end, mentor developers, and shape architecture decisions. If you've outgrown your current environment and want to build something that moves real money for real people, this is your shot.

What You'll Work On

- Microservices: designing service boundaries, inter-service communication, and data consistency across the loan lifecycle (origination, verification, disbursal, repayment, and collections).
- End-to-end feature ownership: from design and development through testing, release, and production.
- RESTful APIs: versioned contracts, pagination, idempotency, error handling, and clean documentation for the mobile app, web app, and internal control panels (ops, credit, marketing).
- Third-party integrations: credit bureaus, DigiLocker, VKYC, Account Aggregator, penny drop, and payment gateways (Razorpay, PayU, Cashfree), with retries, timeouts, webhooks, and reconciliation built in.
- Node.js + MySQL: clean Node.js code with robust MySQL design, including schema design, indexing, query optimization with EXPLAIN, transactions and isolation levels, and large transactional tables (loans, repayments, ledgers).
- Redis in production: caching, session management, rate limiting, and distributed locks (e.g., preventing duplicate disbursal requests).
- AWS operations: EC2, ECS, S3, RDS, SES, CloudWatch, IAM; containerized builds with Docker; safe rollouts and rollbacks through CI/CD.
- Observability and production support: structured logging, metrics, alerting, and incident resolution.
- Compliance by design: consent capture, audit trails, data localization, and PII handling under RBI digital lending guidelines.
- Raising the engineering bar: reviewing code, mentoring developers,



spotting gaps in the current stack (including legacy parts), and driving the plan to fix them.
- Cross-functional work: occasional frontend modules in React or Angular, and close collaboration with product, credit, and ops in an Agile setup.

What We're Looking For

- 4–6 years building large, complex systems, with at least 2 years building and operating microservices in production.
- Node.js (3+ years) with Express.js or similar. You know the event loop and async patterns, and can debug a misbehaving service under load.
- MySQL (4+ years): complex queries, indexing, schema design, InnoDB transactions and isolation levels, and debugging slow queries in production. Postgres experience is welcome, but you'll work in MySQL here.
- Data structures and algorithms: you reason about time and space complexity in real code, not just interview puzzles.
- AWS (2+ years): EC2, ECS, S3, RDS, CloudWatch. Docker required. You've deployed and operated what you built.
- Redis and message queues: caching strategies, plus production experience with SQS, Kafka, or RabbitMQ for async processing.
- CI/CD ownership: you've built pipelines (GitHub Actions, Jenkins, or GitLab CI), not just used them.
- API design and security: REST conventions, OAuth2/JWT, webhooks, versioning, and security fundamentals.
- Frontend (1+ year): React or Angular, enough to ship a module when needed.
- Ownership: you communicate well, meet deadlines, own modules with minimal supervision, and take initiative.

Bonus Points If You've

- Worked in fintech, lending, or high-transaction-volume products: LOS/LMS, NBFC/LSP integrations, payments, or ledger systems.
- Built event-driven architectures or worked with API gateway patterns.
- Worked with PHP: comfortable navigating a legacy PHP codebase, or have modernised one to a newer stack.
- Used infrastructure-as-code (Terraform or CloudFormation).
- Familiarity with RBI digital lending guidelines, KFS, or the Account Aggregator framework.
- Used MongoDB or other NoSQL stores alongside relational databases.
- Worked in a startup or fast-moving product environment.
