A Backend Software Developer Intern assists in building and maintaining the server-side logic, databases, and APIs that power web applications. Their responsibilities typically include writing code, debugging issues, and collaborating with other developers to ensure data flows efficiently between the server and users. Interns often work with languages like Python, Java, or Node.js and gain practical experience with databases, cloud services, and development tools. This role provides valuable exposure to real-world software engineering practices and helps interns develop the technical and teamwork skills needed for a career in backend development.

What are the key skills and qualifications needed to thrive as a backend software developer intern?

To thrive as a Backend Software Developer Intern, you should have a solid understanding of programming languages like Java, Python, or Node.js, and basic knowledge of algorithms, data structures, and databases. Familiarity with version control systems (like Git), RESTful APIs, and cloud platforms such as AWS or Azure is often expected. Strong problem-solving skills, teamwork, and effective communication set standout interns apart. These skills and qualities are crucial for building reliable backend systems, collaborating across teams, and adapting to real-world engineering challenges.

What types of projects and technologies do backend software developer interns typically work on during their internship?

Backend Software Developer Interns are often assigned to work on real-world projects such as building APIs, optimizing databases, or improving existing backend services. Interns typically use languages like Python, Java, or Node.js, and work with frameworks and tools such as Django, Spring Boot, or Express.js. Collaboration with frontend developers, QA engineers, and product managers is common, providing valuable experience in agile environments.

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).
