Exciting Career Opportunity: Senior Integration Layer Developer (Node.js, TypeScript, NestJS)

In today’s fast-paced digital world, integration is at the heart of every successful enterprise system. Businesses rely on seamless connectivity between internal applications, cloud services, and third-party APIs to deliver real-time, data-driven solutions. If you are a backend engineer passionate about solving complex integration challenges using cutting-edge technologies, this is the perfect opportunity for you.

Our company is seeking an experienced Senior Integration Layer Developer who can architect, develop, and maintain a modern, scalable integration platform connecting various systems — especially within the healthcare technology domain.

This role offers the chance to work on mission-critical backend systems, collaborate with talented engineers, and contribute to products that make a real-world impact.

About the Role: Senior Integration Layer Developer

The Senior Integration Layer Developer plays a key role in designing and building the digital backbone of our systems — the layer that connects multiple applications, databases, and external APIs into a unified ecosystem.

You’ll work with Node.js, TypeScript, and NestJS to create highly efficient, secure, and maintainable integration services. Whether you’re orchestrating data flow between microservices, connecting healthcare APIs, or optimizing database interactions, your work will power smooth, reliable communication across our platforms.

This is more than just backend coding — it’s about engineering the core foundation that ensures our products and partner systems work in perfect harmony.

Key Responsibilities

As a Senior Integration Layer Developer, your responsibilities will cover the full spectrum of backend and integration development:

1. Design & Development

You will architect and build a scalable, secure integration layer using Node.js, TypeScript, and NestJS. You’ll apply software design principles to create modular and reusable services that can easily adapt to evolving business requirements.
Experience with Java Spring Boot is a plus, especially when integrating with Java-based systems.

2. API Integration

You’ll develop, maintain, and optimize APIs for seamless communication with third-party systems. From healthcare APIs to cloud-based microservices, you’ll ensure smooth and reliable data exchanges that meet performance and compliance requirements.

3. Problem-Solving & Innovation

This role calls for creativity and technical depth. You’ll analyze complex integration challenges — such as transforming data across formats, handling asynchronous messaging, or managing API throttling — and deliver elegant, maintainable solutions.

4. Agile Development Practices

You’ll work within an Agile/Scrum environment, collaborating with cross-functional teams to deliver incremental improvements. Writing clean, well-documented, and testable code will be part of your daily routine.

5. Database Management

The integration layer connects multiple data sources. You’ll handle relational and non-relational databases, optimizing queries and managing data flow to ensure speed and reliability.

6. Testing & Quality Assurance

You’ll write and maintain unit, integration, and end-to-end tests to ensure code quality, system stability, and reliable deployments.

7. Cloud Deployment & Monitoring

You’ll deploy services on AWS, Azure, or GCP, using modern DevOps tools and cloud-native approaches. Monitoring, scaling, and maintaining performance are key responsibilities.

8. Collaboration & Code Review

You’ll participate in code reviews, pair programming, and technical discussions — sharing knowledge and best practices with fellow engineers.

9. Documentation

You’ll create and maintain detailed technical documentation, ensuring that integrations are transparent, traceable, and easy to maintain for future developers.

10. Architectural Excellence

You’ll apply sound design principles and microservices architecture patterns to ensure the integration layer is resilient, scalable, and secure.

Required Skills & Qualifications

To thrive in this role, you should bring both technical expertise and problem-solving ability.

5+ years of backend development experience.
Strong proficiency in Node.js, TypeScript, and NestJS.
Proven experience in building and managing enterprise-level integrations and APIs.
Working knowledge of modern front-end frameworks (React, Angular, or Vue) for cross-team collaboration.
Solid understanding of relational (MySQL, PostgreSQL) and non-relational (MongoDB, Redis) databases.
Experience deploying and maintaining services on AWS, GCP, or Azure.
Strong analytical skills and a passion for clean, maintainable code.

Preferred / Nice-to-Have Skills

While not mandatory, the following skills will make you stand out:

Experience with Java/Spring Boot for backend service integration.
Familiarity with GraphQL for advanced, flexible API design.
Background in healthcare technology or other regulated industries.
Knowledge of API security protocols (OAuth 2.0, OpenID Connect).
Exposure to microservices architecture and distributed systems.

These skills will help you design integrations that are not only functional but also secure, scalable, and future-proof.

Education & Experience

Bachelor’s or Master’s degree in Computer Science, Software Engineering, or related field (or equivalent experience).
5+ years of hands-on backend and API integration development.
Experience in enterprise-scale systems is highly desirable.
