Senior Backend Developer (PHP / Laravel)

About the Role

We are looking for a Senior PHP / Laravel Backend Developer to design, build, and own the core backend of Sarmaye, a personal finance & fintech product.
You will work closely with Product and Mobile (Flutter) teams to deliver a secure, scalable, and production-ready platform built on Laravel 12.

This role is ideal for someone who thinks in architecture, writes clean and modular code, and enjoys solving complex real-world problems in fintech systems.

Responsibilities

• Design and implement RESTful APIs with clean contracts, versioning, pagination, and proper error handling
• Architect and develop core backend systems for a fintech mobile application
• Build scalable and maintainable backend modules around:
• Authentication & authorization flows
• Bank and external service integrations
• Financial data ingestion and processing
• Budgeting, summaries, and reporting features
• Notifications and event-driven triggers
• Design data models for high-volume transactional data
• Ensure data consistency, correctness, and performance
• Maintain high backend quality through tests, logging, monitoring, and code reviews

Technical Expectations

• Work with Laravel 12 in a production-grade environment
• Write modular, maintainable, and extensible code
• Apply design patterns (Repository, Service, Strategy, Factory, etc.) where appropriate
• Build systems with a clear separation of concerns
• Design APIs consumed by mobile clients (Flutter)

Requirements (Must-have)

• Senior-level experience with PHP and Laravel
• Strong understanding of:
• REST API design principles
• Laravel internals (Service Container, Middleware, Queues, Jobs, Events, Policies)
• Relational databases (PostgreSQL preferred), indexing & query optimization
• Authentication systems (OTP-based auth, tokens, refresh/session handling)
• Caching, rate limiting, and performance optimization
• Experience building modular architectures (domain-based or module-based)
• Familiarity with clean architecture and SOLID principles
• Strong engineering discipline: readable code, tests, documentation, and meaningful PRs
• Ability to think beyond implementation and contribute to system design

Nice to Have

• Experience in fintech, banking systems, or financial data platforms
• Background jobs & async processing (Laravel Queues, Horizon)
• Experience with Docker and basic deployment workflows
• Familiarity with observability tools (logs, metrics, error tracking)
• Awareness of security and privacy best practices for sensitive financial data

What We Value

• Creative and solution-oriented mindset
• Strong architectural thinking
• Ownership mentality — you care about what you build
• Ability to collaborate and challenge ideas constructively
• Writing code that others actually enjoy reading

What Success Looks Like

• Stable and reliable backend under real-world failures
• Clean, scalable transaction and financial data pipeline
• Accurate financial calculations used daily by users
• Production-grade APIs with low error rates and high performance
• A backend codebase that can scale with the product and the team
