About the Role

We are seeking a passionate and skilled Backend Developer to join our fully remote engineering team. You will be a key contributor in designing, building, and maintaining the robust APIs and services that power our platform. You will own your work from conception to deployment and beyond, embracing a culture of quality and problem solving.

Technical Stack

• Core Stack (Required)
• Language: JavaScript (ES6+)
• Runtime: Node.js
• Web Framework: Hapi.js or Express.js
• Database: MySQL
• Paradigm: Strong Object-Oriented Programming (OOP) principles

• Supporting "Good-to-Have" Stack
• Cloud Services (AWS): Lambda, SQS, EC2, RDS, S3
• ORM: Sequelize
• Testing: Mocha, Chai
• Version Control: Git
• Environment: Experience working on projects for US or European markets (data privacy, time zones, etc.)

Roles & Responsibilities

1. 1. API Development & Architecture
2. Design and implement RESTful API endpoints that are intuitive, consistent, and adhere to industry best practices (proper HTTP status codes, standardized response structures, versioning strategies).
3. Develop robust, secure, and well-documented APIs using Node.js with Hapi.js or Express.js.
4. Optimize API performance to reduce latency and improve response times.
5. Incorporate security practices: input validation, sanitization, authentication/authorization checks, and protection against common vulnerabilities (e.g., SQL injection, XSS).

1. 2. Database Management & Optimization
2. Design and maintain efficient MySQL schemas that support business requirements (normalized or strategically denormalized).
3. Write complex, optimized raw SQL queries and use EXPLAIN plans to optimize performance.
4. Utilize Sequelize ORM for standardized data interactions, with ability to fall back to raw SQL for performance-critical operations.
5. Plan and execute safe database migrations to evolve the schema without downtime or data loss.

1. 3. Ownership End-to-End Delivery
2. Act as the Technical Owner for specific product components or services, including health and future direction.
3. Full lifecycle involvement: requirements discussion, technical specs, development, testing, deployment, and post-launch monitoring.
4. Evaluate multiple approaches, considering trade-offs in scalability, maintainability, and time-to-market.
5. Collaborate on Deployment DevOps: contribute to CI/CD pipelines and infrastructure discussion for AWS serverless components like Lambda and messaging with SQS.

1. 4. Quality Assurance Testing
2. Write clean, maintainable code following OOP principles and style guidelines.
3. Develop unit tests with Mocha and Chai (or Jest/Sinon) and strive for high test coverage.
4. Participate in code reviews to maintain code quality and adherence to standards.
5. Debug and troubleshoot issues across environments (development, staging, production).

1. 5. Collaboration & Communication
2. Work closely with front-end engineers to define API contracts and with product managers for requirements and feasibility feedback.
3. As a fully remote team member, excel in asynchronous communication and document work clearly using tools like Slack, Jira, or Confluence.
4. Share knowledge and mentor others to help the team grow.

1. 6. Proactive Initiatives (Nice-to-Haves)
2. Experience with AWS Lambda and SQS for serverless architectures.
3. Experience with US/European projects and data privacy considerations (GDPR, CCPA).
4. Proactive identification of technical debt and infrastructure improvements; stay updated with new technologies.
