What is a fullstack Java developer?

A Fullstack Java developer is a software professional skilled in both front-end and back-end development using Java and related technologies. They are capable of building complete web applications, handling everything from user interface design to database management and server-side logic. Typically, they work with Java frameworks like Spring or Java EE on the backend, and may use front-end technologies such as HTML, CSS, JavaScript, and frameworks like Angular or React. Fullstack Java developers are valued for their versatility and ability to manage end-to-end software projects.

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

To thrive as a Fullstack Java Developer, you need strong proficiency in Java, front-end technologies (like HTML, CSS, JavaScript), and frameworks such as Spring and Angular or React, often supported by a relevant degree or certifications. Familiarity with databases (SQL/NoSQL), version control systems (like Git), and CI/CD tools is typically required. Problem-solving ability, effective communication, and adaptability are standout soft skills for collaborating across teams and addressing dynamic project needs. These capabilities are crucial for delivering robust, scalable applications and ensuring seamless integration between front-end and back-end systems.

What are some common challenges fullstack Java developers face when working on cross-functional teams?

Fullstack Java developers often collaborate with front-end, back-end, and DevOps teams to deliver end-to-end solutions. A common challenge is ensuring smooth integration between different technological stacks and managing communication gaps among team members with diverse expertise.

Job description

Role overview

The Developer Experience Architecture team at CarGurus builds the platforms, tooling, and standards that make hundreds of engineers faster, safer, and more productive. You will work on our highest-leverage initiatives: standardizing AI agentic development (Claude Code, our internal plugin marketplace, and MCP integrations), evolving our authentication and identity platform (Keycloak, OAuth2/OIDC), and improving the paved paths for service and job creation on AWS. These are complex, cross-cutting problems with global impact. You will own your projects and partner with engineers and product managers across the org. And no, you do not need to know about cars to work here.

What you'll do

  • Design and ship developer tooling, core frameworks, and reusable templates that raise engineering productivity and quality
  • Advance our agentic development ecosystem: Claude Code configuration and governance, plugins and skills, and MCP servers
  • Strengthen the Auth service and agent identity model using Keycloak, OAuth2, and OIDC
  • Build and operate services with Java, Spring Boot, AWS, and Kubernetes
  • Define standards, guardrails, and best practices, then drive adoption across product teams
  • Continuously assess, root cause, and improve system reliability and performance
  • Define, communicate, and drive technical solutions and complex projects from concept through successful completion, ensuring clear direction, accountability, and measurable outcomes
  • Partner effectively across teams to influence decisions, resolve complex technical challenges, and build alignment without relying solely on direct authority
  • Demonstrate strong business judgment by prioritizing work based on customer and business impact, translating technical decisions into measurable outcomes, and consistently focusing on delivering meaningful results.

What you'll bring

  • Eight or more years of hands-on, fullstack software design and development, including at least five years of Java.  Experience with client and server side JavaScript, including React, Node, and Remix, along with Terraform experience is a plus
  • Experience building performant, large-scale web applications and cloud-native systems on AWS or similar cloud providers
  • Working knowledge of authentication and identity standards (OAuth2/OIDC), or a strong appetite to learn them
  • Hands-on experience applying modern AI coding tools (assistants, agents, MCP) to real engineering work
  • Comfort writing tests, using observability tools, and owning projects end to end
  • Curious, collaborative, and eager to learn
  • Demonstrated deep expertise in a relevant technical stack, including critical code reviews, scalability, architecture, testing strategy, performance, and cross-team integration.
  • Bachelor's degree in Computer Science or equivalent
