Job summary

Essex Property Trust in Irvine, CA seeks a Senior Application Developer to design, build, and support complex apps on a serverless, cloud-native stack using AI-first workflows. The role emphasizes owning architecture, specs, tests, and code reviews, while leveraging AI agents to accelerate delivery.

The Essex Technology team fosters collaboration among technologists, solving problems and driving a tech-forward future with a strong focus on scalable, secure, user-centric solutions.

Qualifications

• Bachelor’s degree in computer science, engineering or related discipline.
• 8+ years of hands-on full stack web application development across the full lifecycle: requirements, design, build, test, deployment, and support.
• Deep knowledge of software architecture and design patterns (e.g., separation of concerns, modular design, API design).
• Strong automated testing skills (unit, integration, end-to-end, regression) and test-driven development.
• Proficient in capturing workable requirements from end users and business stakeholders and writing specifications clear enough for an engineer, or an AI agent, to implement without ambiguity.
• Strong code-review skills to assess AI-generated code for correctness, security, and maintainability.
• Experience with AI coding tools (e.g., Claude Code, GitHub Copilot, Cursor), or a demonstrated eagerness to adopt them.
• Experience building serverless applications (e.g., AWS Lambda, Vercel) with CI/CD and DevOps practices.
• Strong knowledge of HTML5, CSS, JavaScript, and at least one backend language.

Responsibilities

• Design and develop web applications for internal and external customers, using agentic AI tools to plan, implement, and iterate quickly while applying sound usability concepts.
• Build on our serverless architecture (e.g., AWS, Vercel) across front-end UI, back-end APIs, and data, using low-code tools where they fit, to deliver scalable, secure, user-centric solutions.
• Work with business stakeholders to shape requirements and translate them into clear functional specifications and acceptance criteria that drive AI-assisted implementation.
• Define architecture, data models, and design patterns, and guide AI agents to implement within them.
• Own test strategy: unit, integration, and regression suites that validate AI-generated code.
• Take a lead role in code quality, security, and performance, critically reviewing AI-generated code.
• Maintain, support, and modernize existing applications, using AI to analyze, document, and refactor legacy code.
• Help lead architecture and design reviews, backlog refinement, and other scrum meetings.
• Triage and resolve production issues, and deploy changes through automated CI/CD pipelines.
• Contribute to technology best practices, including the secure, responsible use of AI tools.
