The role of a Backend Developer at Bijoy Online Limited centers on building and maintaining the technical backbone of their services, particularly for managing internet subscriptions and payment systems. You’ll work closely with teams to design secure, scalable APIs that handle recurring billing, invoicing, and transaction data. Since the company operates in Bangladesh, your work will involve integrating local payment gateways like SSLCommerz, BKash, and Nagad, alongside international platforms. This role requires a strong focus on data integrity, security, and system performance to support their nationwide operations.
• Technical expertise in Node.js (Express or NestJS) is essential for API development
• Payment gateway integration experience, especially with local providers, is critical
• Database management skills in PostgreSQL, MySQL, or MongoDB to ensure data accuracy
• Security protocols like JWT and OAuth must be well understood to protect sensitive transaction data
• Automated testing knowledge using tools like Mocha or Jest to ensure code reliability
• Cloud deployment familiarity with AWS, GCP, or Azure for scalable server solutions
• Billing logic proficiency in managing invoices, ledgers, and recurring payment schedules
Candidates should highlight projects that demonstrate hands-on experience with ISP billing systems, payment reconciliation, or similar IT-enabled services. Local experience, particularly in Bangladesh’s telecom or fintech sectors, will strengthen your application. If you’ve worked with NGOs or INGOs on tech projects, mention those as they align with the company’s focus on scalable, community-focused solutions. Emphasize compliance with data protection laws and field-based problem-solving, as these are key in a service-driven environment.
Your education should reflect a Master’s in Science (MSc) or equivalent, with a focus on computer science or related fields. Include certifications in Node.js, payment gateway integration, or cloud platforms to showcase specialized training. When listing your experience, prioritize roles that involve API development, database optimization, and security measures. Avoid vague statements—instead, provide specific examples of systems you’ve built or improved.
Tools like Docker for containerization and cloud platforms like AWS are practical must-haves. Demonstrate how you’ve used these to streamline deployments or enhance system performance. For databases, explain how you’ve optimized queries or managed indexing to improve efficiency. During interviews, be ready to discuss real-world scenarios, such as troubleshooting payment gateway errors or designing secure billing workflows.
1. Research the company to understand their services and how your skills align with their needs
2. Prepare technical answers on payment integration, API security, and database management
3. Practice explaining complex concepts in simple terms, as Bangladeshi employers value clarity
4. Review your projects and be ready to discuss challenges, solutions, and outcomes
5. Anticipate questions about teamwork, problem-solving, and adaptability in fast-paced environments
Ensure your CV includes all relevant certifications, references from previous employers, and a clear summary of your technical expertise. Carry physical copies of your documents if required, and be prepared to discuss your field readiness—such as familiarity with local payment systems or experience working in Dhaka’s tech ecosystem. Professional behavior, including punctuality and respectful communication, will leave a lasting impression. Stay confident, be honest about your experience, and show how your skills directly support Bijoy Online Limited’s mission.
