Backend Engineer Java information

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?

Position Title: JavaScript Full Stack Developer Intermediate
Location: Ottawa, ON (377 Dalhousie Street)
Work Model: Hybrid - 4 days onsite, 1 day work from home
About Rebel
OUR CUSTOMERS BRING A VISION - WE BRING THE PLATFORM TO SHARE IT ONLINE.
We believe that those who contribute make us better.  It’s why we create simple, useful tools to empower participation in the world’s bravest communication space: the Internet.
We are experts in domain names and the products that make the most of them.  This helps our customers showcase their ideas, stories, services and contributions to the world. 
Our manifesto: Be Thoughtful, Be Simple, Be Brave.
Role Overview
As an Intermediate JavaScript Full Stack Developer, you’ll help build and evolve Rebel’s customer-facing products and internal services that power our domain and hosting platform. You’ll contribute across the stack—React on the front end and Node.js (with some legacy .NET) on the back end—delivering well-scoped features and improvements.
You’ll work closely with Product and cross-functional partners to turn requirements into reliable, scalable solutions, and you’ll strengthen quality through clean code, automated testing, and participation in deployments and production support.
This role is ideal for someone who can work independently on most tasks, collaborates well through reviews and pairing, and is ready to grow their technical depth and impact within a modern cloud environment.
What You’ll Do
  • Contribute to technical initiatives across software development and operations teams, supporting alignment with business goals and engineering best practices.
  • Work with product and engineering teammates to translate business requirements into practical, scalable solutions, considering architecture, security, and performance.
  • Participate in knowledge sharing through peer reviews, pairing, and documentation, while continuously building your own skills and expertise.
  • Collaborate with cross-disciplinary partners (Engineers, Product Owners, Marketing, Customer Service, and stakeholders) to design, build, and deliver high-quality product improvements
  • Build and improve reusable UI components using modern front-end technologies (React) to create clear, accessible, and engaging user experiences.
  • Develop and maintain back-end services and APIs using Node.js (and .NET where applicable), focusing on reliability, scalability, and clean integration patterns.
  • Write clean, modular, and reusable code by following established standards, patterns, and best practices in the codebase.
  • Contribute to feature design, implementation, and iteration using agile practices, incorporating feedback, monitoring results, and improving over time.
  • Support testing and deployment activities by writing automated tests, following release processes, and helping ensure quality and stability in production.
  • Stay current with relevant technologies and best practices, bringing forward ideas and suggestions to improve the product and development workflow.
  • Explore and apply AI-assisted tools (where appropriate) to improve productivity, quality, and delivery speed.
  • Participate in active system support, bug fixing and incident resolution as needed.

What You Bring
  • 3–8 years of professional software development experience working with modern application stacks (Node.js, React).
  • Strong JavaScript/TypeScript proficiency, including modern ES6+ features and common patterns.
  • Hands-on experience building and maintaining Node.js services (e.g., Express.js) and designing/consuming RESTful APIs.
  • Practical experience working in AWS (or a comparable cloud platform), including deploying and operating cloud-based applications.
  • Exposure to cloud architecture concepts such as microservices, event-driven patterns, and distributed systems, with the ability to implement features within existing architectures.
  • Experience working in Scrum/Agile teams and contributing effectively to sprint-based delivery (planning, estimates, demos, retros).
  • Ability to contribute to modernization efforts (refactoring, improving reliability/performance, incremental migration) with guidance.
  • Solid experience with Git and collaborative workflows (pull requests, code reviews, branching strategies).
  • Experience working with CI/CD pipelines and contributing to automated testing (unit/integration), quality checks, and release processes.
  • Familiarity with Infrastructure as Code concepts/tools (CloudFormation, CDK, or Terraform) and the ability to make safe changes with support.
  • Container experience (Docker; ECS/EKS is a plus) and understanding of how containerized apps are built and deployed.
  • Familiarity with legacy systems (e.g., .NET Framework and/or Java) and comfort making small updates when needed.
  • Desire to learn and grow your career

What We Offer
  • A collaborative, high-performance workplace that recognizes hard work and creative thinking, with competitive compensation, benefits, and opportunities for growth.
  • A smoke-free, downtown office with thoughtful perks, including a fully stocked staff fridge.
  • Comprehensive training in domain registration, web hosting platforms, and troubleshooting tools.
  • A dedicated workspace, a supportive team environment, and ongoing professional development.
  • A people-centered culture that values your expertise, ideas, and long-term career growth.

Who We’re Looking For
People who care. About customers. About teammates. About doing the right thing even when it’s the harder thing. You don’t need to know every acronym (yet), but you should love learning, solving problems, and keeping cool when tech gets tricky. If you’re kind, curious, reliable, and maybe a little cheeky—you’ll fit right in.
