Junior Java Developers usually have foundational knowledge of Java and related technologies, and they are eager to develop their skills through hands-on experience.

What does a junior Java developer do?

Junior Java developers are entry-level programmers who are part of a team of coders and developers. They work on both front-end and back-end codes to build an application.

As a junior Java developer, you run tests to pinpoint errors, migrate code and data, and ensure the program is integrated with other company developments.

What are the key skills and qualifications needed to thrive as a junior Java developer?

A Junior Java Developer should have a solid understanding of Java programming, object-oriented principles, and basic software development concepts, often supported by a relevant degree or coding bootcamp.

Strong problem-solving abilities, attention to detail, and effective teamwork are important soft skills in this role. These competencies enable efficient code development, smooth collaboration, and the ability to quickly adapt to new technologies and project requirements.

What are some common challenges a junior Java developer might face during their first year, and how can they overcome them?

Junior Java Developers often encounter challenges such as understanding large codebases, adapting to agile development processes, and managing task priorities. To overcome these hurdles, it’s helpful to proactively seek mentorship from senior developers, regularly review documentation, and participate in code reviews. Effective communication with team members also accelerates learning and helps clarify requirements or technical uncertainties. Embracing continuous learning through online resources and hands-on projects will further strengthen your skills and confidence.

We're building new mobile and web experiences that help gamers connect, discover, and play together in better ways. This is a rare opportunity to build at startup speed and deliver significant impact inside one of the largest gaming companies in the world.

We are seeking a Senior Backend Software Engineer to help define the architecture, services, data models, and technical standards that power our new consumer experiences.

Responsibilities

  • Define and evolve the backend architecture for highly available, scalable consumer applications across mobile and web.
  • Design, build, test, deploy, and operate reliable backend services and APIs.
  • Design data models and storage strategies across relational, non-relational, caching, and event-driven systems.
  • Make thoughtful architectural decisions related to scalability, consistency, availability, latency, security, and cost.
  • Drive performance optimization, service reliability, observability, monitoring, and incident response best practices.
  • Establish coding standards, testing strategies, deployment patterns, and development practices that raise the quality bar for backend engineering.
  • Partner with product managers, designers, and client engineers to translate product requirements into maintainable technical solutions.
  • Mentor engineers and act as a multiplier for backend development expertise across the broader team. 
  • Collaborate with security, privacy, and platform teams to ensure systems meet appropriate data protection and compliance requirements.
     

 Requirements

  • 5+ years of professional software development experience building and operating backend services in production.
  • BS/MS degree in Computer Science, Software Engineering, or equivalent practical experience.
  • Proficiency in server-side development (Node.js with TypeScript preferred).
  • Experience with relational and non-relational databases, including data modelling, indexing, transactions, and performance optimization (PostgreSQL preferred).
  • Demonstrated ability to design and build GraphQL and REST APIs.
  • Familiarity with caching, message queues, event streams, and asynchronous processing systems.
  • Solid understanding of cloud infrastructure, containerized services, CI/CD pipelines, and infrastructure as code (IaC).
  • Hands-on experience building and operating production systems on AWS, including compute, storage, networking, databases, and IAM.
Bonus
  • A track record of building social, community, gaming, or other consumer products.
  • Understanding of real-time communication systems, including messaging, presence, notifications, and activity feeds.
  • Experience designing social graphs, recommendation systems, content discovery services, or personalization platforms.
  • Experience with trust and safety, content moderation, abuse prevention, or user reporting systems.
  • Previous experience at an early-stage startup or on a zero-to-one product team.
