Position Overview

Ray Advertising is on the hunt for a technically strong, English-fluent API Developer who can build scalable REST APIs and also communicate effectively with U.S. clients. This is not your typical back-office developer role — we’re looking for someone who writes clean code and can represent our company in English during technical discussions, demos, and handovers. It is a night-shift position for those who are self-motivated, detail-oriented, and fluent in English.

Key Responsibilities

As an API Developer at Ray Advertising, your role will go beyond writing code — you’ll be a core contributor to both the technical architecture and the client experience. You will:

API Development & Integration:

• Design and implement secure, scalable, and maintainable RESTful APIs to support CRUD operations on user data using modern backend technologies (e.g., Node.js, Python).

• Design consistent and intuitive RESTful APIs with proper use of HTTP methods (GET, POST, PUT, PATCH, DELETE).

• Use appropriate HTTP status codes (2xx, 4xx, 5xx) and deliver clear, structured error responses.

• Apply resource modeling and REST principles to design clean, stateless API endpoints.

• Implement input validation, error handling, and structured error messaging for better API reliability and client-side debugging.

• Integrate with third-party services and APIs when needed, ensuring reliability and performance.

Database Design & Management:

• Design and manage relational database schemas (e.g., MySQL, PostgreSQL, MongoDB, etc.) that efficiently store user data; optimize queries for performance.

• Write optimized queries for data retrieval, insertion, and updates with scalability in mind.

• Implement data consistency, constraints, and indexing to ensure high-performance data handling.

Testing, Debugging & Documentation:

• Debug and troubleshoot API issues using various tools (e.g., Postman, Insomnia, and cURL).

• Write unit and integration tests to ensure the accuracy and reliability of your endpoints.

• Debug API issues efficiently using logs, tools, and systematic testing methods to trace issues and deliver fixes quickly.

• Create and maintain comprehensive technical documentation for APIs, endpoints, workflows, integrations and systems developed for internal use and client transparency.

Frontend Integration (Basic):

• Build or contribute to a lightweight front-end interface (e.g., HTML, CSS, JavaScript) that interacts with your API for CRUD operations.

• Implement form-based input with real-time validations and API calls.

• Ensure the frontend dynamically reflects the data stored in the database (display all records, edit/delete options, etc.).

Client Communication & Collaboration:

• Participate in direct calls and meetings with U.S.-based clients, understanding their needs and translating them into actionable development tasks.

• Provide technical insights, timelines, and progress updates in fluent spoken and written English.

• Demonstrate project deliverables to clients, handle live feedback, and offer technical support when needed.

• Collaborate with the internal design, QA, and leadership teams to ensure smooth project flow and timely delivery.

Required Qualifications 

Technical Skills

• Strong understanding of JavaScript (Vanilla), SQL, and RESTful design.

• Solid grasp of HTTP methods, error handling, status codes, and statelessness.

• Hands-on experience with relational databases (e.g., MySQL, PostgreSQL).

Soft Skills

• Excellent English communication skills (verbal and written)
