• Design optimized database schemas, migrations, indexes, and queries.
• Implement secure authentication, authorization, and role-based access control.
• Build APIs consumed by our Flutter mobile application and contribute to our web platform when required.
• Write unit, integration, and end-to-end tests.
• Review code and maintain high standards for performance, scalability, security, and documentation.
• Support deployments, monitoring, debugging, and production issue resolution.
• Collaborate with product, design, and engineering teams to continuously improve the platform.

What We're Looking For

• 6–8 years of experience building and shipping production backend systems.
• Strong experience designing and developing REST APIs using modern backend technologies.
• Full-stack capability with the ability to contribute to frontend development when required.
• Experience building payment systems, financial transaction workflows, or escrow platforms.
• Strong understanding of relational database design, transactions, indexing, and performance optimization.
• Experience integrating third-party APIs and payment gateways.
• Solid understanding of authentication, authorization, API security, validation, and rate limiting.
• Experience with cloud platforms (AWS, Azure, or GCP), containerization, and scalable architectures.
• Familiarity with CI/CD pipelines, Git, automated testing, and modern development workflows.
• Experience using AI-assisted development tools such as Cursor, GitHub Copilot, Claude Code, or similar while maintaining strong engineering judgment and code quality.
• Strong communication, ownership mindset, and problem-solving skills.

Nice to Have

• Experience building backend systems for Flutter applications.
• Experience with Redis, caching, queues, and background jobs.
• Experience working in an early-stage startup or product company.
• Familiarity with microservices and distributed systems.

Why Join Trendlance?

• Build a live product used by real users.
• Work directly with the founders and influence technical decisions.
• Take ownership of meaningful engineering challenges from day one.
• Help shape the architecture, engineering culture, and future direction of the product.
