What does a backend engineer Java do?

A Backend Engineer Java is responsible for developing and maintaining the server-side logic, databases, and application programming interfaces (APIs) using the Java programming language. They ensure that the backend of web applications or software systems is efficient, secure, and scalable. Their work often involves collaborating with frontend developers, designing system architecture, and optimizing performance to handle large volumes of user requests. Backend Java engineers often use frameworks such as Spring or Hibernate and work with databases like MySQL or PostgreSQL.

What are the key skills and qualifications needed to thrive as a backend engineer Java?

To thrive as a Backend Engineer Java, you need a solid understanding of Java programming, data structures, algorithms, and experience with backend frameworks, typically supported by a relevant degree or industry experience. Familiarity with tools and technologies such as Spring Boot, RESTful APIs, relational databases, and build systems like Maven or Gradle is commonly required. Problem-solving ability, teamwork, and effective communication are crucial soft skills for excelling in collaborative and fast-paced development environments. These combined skills ensure robust, scalable backend systems that meet business needs and integrate smoothly within larger software architectures.

How does a backend engineer Java typically collaborate with frontend developers and other stakeholders in a project?

As a Backend Engineer Java, you will regularly collaborate with frontend developers to ensure seamless integration between server-side logic and user interfaces. This often involves participating in design discussions, clarifying API requirements, and troubleshooting integration issues. You’ll also engage with product managers, QA engineers, and sometimes DevOps teams to align on project goals, timelines, and deployment strategies. Effective communication is key to translating business requirements into reliable backend solutions and maintaining smooth workflows across the team.

What is the difference between Backend Engineer Java vs Backend Developer Java?

AspectBackend Engineer JavaBackend Developer Java
Primary FocusDesigning, developing, and maintaining server-side applications and systemsImplementing and coding backend functionalities based on specifications
ResponsibilitiesSystem architecture, performance optimization, API developmentWriting code, debugging, integrating databases
Skills & CertificationsJava, Spring, REST APIs, SQL, cloud platformsJava, Spring, SQL, version control, testing tools
Work EnvironmentCollaborative teams, project planning, architecture designCode implementation, debugging, feature development

Both roles require Java expertise and similar certifications, but Backend Engineer Java typically involves higher-level system design and architecture responsibilities, while Backend Developer Java focuses more on coding and implementing features. Employers often see these roles as complementary within software development teams.

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).
