What is a back end developer?

A Back End Developer is a programmer who specializes in building and maintaining the server-side logic, databases, and application functionality that power websites and web applications. Unlike front end developers, who focus on the visual and interactive elements users see, back end developers work behind the scenes to ensure data is stored, processed, and delivered correctly. They typically use programming languages like Python, Java, Ruby, or PHP, and interact with databases such as MySQL or MongoDB. Their work is crucial for making sure applications run smoothly, securely, and efficiently.

What is a back end developer?

A back end developer is a computer science professional who specializes in functionality that takes place on the server side or backend. As a back end developer, you write code to create software that solves a business need. Your responsibilities are to research the needs of either your employer, or a particular industry, find a problem, and create a software solution. A back end developer differs from a traditional web developer, or front end developer, in that back-end software may not have a user interface or even have exposure to the web.

What are the key skills and qualifications needed to thrive as a back end developer?

To thrive as a Back End Developer, you need strong programming skills in languages like Java, Python, or Node.js, along with a solid understanding of databases and API design, typically supported by a degree in computer science or related experience. Familiarity with frameworks such as Spring or Django, version control systems like Git, and cloud platforms (e.g., AWS or Azure) is often required, with certifications in these areas considered beneficial. Problem-solving, effective communication, and teamwork are crucial soft skills that help developers collaborate and address complex technical challenges. These competencies are vital for building reliable, scalable systems that support front-end applications and ensure robust product performance.

What are some common challenges back end developers face when integrating with front-end teams?

Back End Developers often encounter challenges when aligning data structures and APIs with front-end requirements, especially as user interface needs evolve rapidly during development. Effective communication and regular collaboration with front-end developers are essential to ensure that endpoints, data formats, and error handling are well-coordinated. Additionally, maintaining consistent documentation and using tools like Swagger or Postman can help streamline integration and reduce misunderstandings between teams.

What is the difference between Back End Developer vs Front End Developer?

AspectBack End DeveloperFront End Developer
Primary FocusServer-side logic, databases, APIsUser interface, website layout, client-side scripting
Skills & TechnologiesLanguages like Java, Python, Ruby; databases; server managementHTML, CSS, JavaScript, frameworks like React or Angular
Work EnvironmentBackend systems, server environments, cloud platformsDesign tools, browser testing, UI/UX design
Common CertificationsCertified Web Developer, AWS Certified DeveloperCertified Front End Developer, UI/UX certifications

Back End Developers focus on server-side logic, databases, and APIs, ensuring the website's functionality behind the scenes. Front End Developers work on the visual and interactive aspects users see and interact with. Both roles are essential in web development, often collaborating to create seamless digital experiences.

Is back end developer in demand?

Back end developers are in high demand due to the growth of web applications and digital services. Skills in programming languages like Python, Java, or Node.js, along with knowledge of databases and APIs, are highly sought after by employers across various industries.

Job description

Backend API's and Integrations Software Engineer III
Are you a Backend API developer looking to work for a mission driven global organization?
About the role: We're seeking a Software Engineer III with strong backend engineering skills to design, build, and operate distributed integration services and APIs at scale. You will focus on Kong API Management, backend API lifecycle (setup, testing, maintenance), HL7 FHIR, and enterprise integrations, primarily using Java and JavaScript. The ideal candidate has solid network fundamentals, can work comfortably with YAML (for declarative configs and pipelines), and thrives in pragmatic, production-oriented engineering-no frontend development in this space.
About the team, this team is building a generative-AI-powered clinical decision support tool designed specifically to help healthcare professionals quickly find trusted, evidence-based answers at the point of care. It combines a massive curated medical knowledge base with conversational AI so clinicians can ask questions in natural language and get concise, clinically relevant responses backed by real scientific evidence.
Responsibilities
  • Design & Build Distributed Services
    • Implementing resilient, observable microservices and integration components (Java preferred; Node.js/JavaScript where appropriate).
    • Applying patterns for scaling, fault tolerance, idempotency, and backpressure in distributed environments.
  • API Platform & Kong APIM
    • Configuring and managing Kong Gateway (routes, services, plugins, rate limiting, auth, mTLS, logging) via declarative config (YAML) and CI/CD.
    • Implementing gateway policies for security, traffic control, blue/green/canary releases, and zero-downtime migrations.
  • Integrations & Data Facades
    • Building and maintaining a FHIR data facade that maps internal domain data to FHIR resources (read/search/transform), ensuring correctness and performance.
    • Developing backend integrations with downstream systems (REST, gRPC, messaging/queues) and handle schema/contract evolution.
  • API Engineering
    • Owning the API lifecycle: design (OpenAPI), implementation, automated testing (unit/integration/contract), versioning, and SLO-driven operations.
    • Creating and maintaining OpenAI specs, mocks, and validation pipelines.
  • Security & Compliance
    • Implementing OAuth2/OIDC flows, token introspection, and service-to-service auth. Apply secure coding practices and least-privilege network policies; partner with InfoSec on reviews.

Required Qualifications
  • 3+ years of Professional Experience in backend software engineering.
  • Languages: Proficient in Java; working proficiency in JavaScript/Node.js.
  • API & Integrations: RESTful API design, OpenAPI/Swagger, contract testing, backward compatibility/versioning.
  • API Gateway / Kong APIM: Hands-on experience configuring routes, plugins, auth, rate limiting, and declarative YAML configs; CI/CD integration.
  • Distributed Systems: Understanding of microservices fundamentals: statelessness, service discovery, retries/circuit breakers, caching.
  • Networking Fundamentals: TCP/IP, DNS, TLS/mTLS, HTTP/2/HTTP/1.1, proxies, load balancing, and common troubleshooting (cURL, traceroute, etc.).
  • Data & FHIR Facade: Experience working with HL7 FHIR or adapters; familiarity with FHIR resource modeling and transformations (e.g., Patient, Observation, Encounter).
  • Testing & Quality: Unit, integration, and contract testing; test automation and CI/CD pipelines (YAML-based workflows).
  • Cloud & Ops: Experience deploying and operating services in a cloud or containerized environment (Docker/Kubernetes).
