What does a JavaScript backend developer do?

A JavaScript Backend Developer is responsible for building and maintaining the server-side logic, databases, and APIs that power web applications. They use JavaScript, often with frameworks like Node.js, to process requests, manage data, and ensure smooth communication between the frontend and backend of an application. Their work ensures that web applications are scalable, secure, and efficient. JavaScript Backend Developers also collaborate with frontend developers and other team members to deliver seamless user experiences.

What are the key skills and qualifications needed to thrive as a JavaScript backend developer, and why are they important?

To thrive as a Javascript Backend Developer, you need strong proficiency in JavaScript (especially Node.js), knowledge of backend frameworks, and a solid understanding of databases such as MongoDB or PostgreSQL. Familiarity with development tools like Git, RESTful APIs, Docker, and cloud platforms, as well as relevant certifications, is highly valuable. Excellent problem-solving, teamwork, and communication skills help you collaborate effectively and deliver robust solutions. These abilities are crucial for building scalable, secure, and maintainable backend services that power modern applications.

What are the typical challenges a JavaScript backend developer faces when scaling applications for high traffic?

JavaScript Backend Developers, especially those working with Node.js, often encounter challenges related to handling high concurrency, optimizing database queries, and maintaining application performance under heavy load. Ensuring efficient memory management and implementing robust error handling are also critical when scaling. Working closely with DevOps and frontend teams to optimize APIs and monitor system health is essential for delivering reliable, scalable backend solutions.

Back-End Developer
Magento 2/Adobe Commerce | PHP | MySQL | APIs | Integrations
Full-Time | Easton, PA | On-Site
About Famous Cigars
Famous Cigars has roots as Famous Smoke Shop-PA, Inc. and has been part of the premium cigar industry since 1939. What began as a small family business has grown into a respected name across retail, catalog, e-commerce, and hospitality. Based in Easton, PA, we are known for our product knowledge, customer service, and the experience we create for our customers.
The Opportunity
Famous Cigars is seeking a hands-on E-Commerce Back-End Developer to help own and improve the technology behind our online commerce platform. This role is centered on PHP and Magento 2/Adobe Commerce back-end development, including custom modules, APIs, integrations, MySQL, performance, deployments, and production support.
This is a strong fit for a developer who enjoys solving practical business problems across commerce, data, ERP integrations, order flow, and customer experience. It is not primarily a front-end role, although working JavaScript knowledge is required for troubleshooting and cross-functional development work.
What You Will Do
  • Build, maintain, and enhance Magento 2/Adobe Commerce back-end functionality using PHP.
  • Develop custom modules, services, cron jobs, integrations, API endpoints, and automated business processes.
  • Work with SQL/MySQL to troubleshoot data, improve queries, support reporting, and maintain data integrity.
  • Use XML, dependency injection, events/observers, plugins, and established Magento development patterns.
  • Develop and support GraphQL and REST APIs connecting Magento with NetSuite, Celigo or similar middleware, payment, loyalty, CMS, marketing, and operational systems.
  • Manage PHP dependencies with Composer and development environments with Docker.
  • Use Git, pull requests, code review, testing, and deployment workflows to deliver reliable changes.
  • Troubleshoot production issues across application, database, API, and integration layers and complete root-cause analysis.
  • Improve caching, indexing, query efficiency, API performance, platform reliability, and overall e-commerce performance.
  • Use working JavaScript knowledge to troubleshoot storefront behavior and collaborate with front-end developers.
  • Partner with IT and business teams to turn operational needs into practical, maintainable technical solutions.
Required Experience and Skills
  • 3-6+ years of professional back-end web development experience; production e-commerce experience strongly preferred.
  • Strong PHP development experience.
  • Hands-on Magento 2/Adobe Commerce back-end development experience.
  • Strong SQL/MySQL skills, including joins, query analysis, troubleshooting, and performance optimization.
  • Experience with XML configuration, GraphQL APIs, and REST APIs.
  • Experience with Composer, Docker, and Git.
  • Working JavaScript knowledge.
  • Strong production troubleshooting, debugging, root-cause analysis, and communication skills.
Helpful Experience
  • NetSuite, Celigo or similar middleware, ERP, payment, loyalty, CMS, or marketing-system integrations.
  • Adobe Commerce Cloud, CI/CD, Linux, AWS, GCP, Redis, Varnish, OpenSearch/Elasticsearch, message queues, or Magento indexing and caching.
  • Large product catalogs, inventory, pricing, promotions, checkout, orders, fulfillment, and reporting workflows.
  • React, Next.js, headless commerce, GraphCommerce, PWA Studio, Hyva, or similar front-end frameworks.
  • E-commerce security, privacy, PCI, and secure coding practices.

Location and Schedule
  • On-site Monday through Friday at our Easton, PA headquarters.
  • Core business hours are 8:00 a.m. to 5:00 p.m.
  • Occasional flexibility may be needed for deployments, critical deadlines, or urgent production issues.
  • On-call coverage may occasionally include evenings, weekends, or holidays.
  • A hybrid schedule may be considered for the right highly qualified candidate after discussion; this role is not fully remote.
Why Join Famous Cigars
  • Competitive compensation and benefits.
  • Meaningful ownership of Magento, PHP, database, integration, and production-support work.
  • Direct impact on customer experience, site reliability, checkout, and internal operations.
  • Cross-functional exposure and long-term platform growth opportunities.
How to Apply
Submit your resume highlighting your Magento 2/Adobe Commerce, PHP, MySQL, API, integration, Composer, Docker, Git, and production-support experience.
