As a Senior Java Developer, you will be a hands-on senior engineer responsible for designing, building, enhancing, and supporting web-based insurance applications, primarily on Guidewire InsuranceNow, to meet business goals. You will deliver high-quality code, contribute to architecture and design decisions, and improve performance, stability, and supportability across the portfolio. This is an individual contributor role: success is measured by technical delivery, engineering quality, and operational excellence, not people management.

What you can expect:

• Culture of innovation, teamwork, supportive colleagues and leaders willing to invest in talent
• Internal mobility opportunities 
• Visibility to senior leaders and partnership with cross functional teams
• Opportunity to impact change
• Benefits – competitive compensation, paid time off, comprehensive wellness benefits and programs, employer funded health savings account, profit sharing, 401k, paid parental leave, employee stock purchase plan, tuition assistance and professional continuing education

We'll count on you to:

• Build and enhance InsuranceNow-based Java solutions to support business requirements, including configuration/customization within vendor-provided software.
• Design and implement significant new functionality with attention to performance, stability, scalability, and supportability. 
• Develop, test, document, and support software solutions across the full lifecycle, from requirements through production support.
• Partner with business users and technical teammates to troubleshoot issues, perform root-cause analysis, and drive resolution across application, middleware, and infrastructure layers.
• Produce design specifications that demonstrate understanding of interfacing systems and supported business processes.
• Create and execute test plans, analyze results, and remediate defects to improve quality and reliability.
• Raise engineering quality through thoughtful code reviews, design discussions, and improving standards (without formal “management” accountability). 
• Proactively identify improvements to supportability and usability; recommend solutions to business problems using current technology and best practices.
• Monitor and assess performance metrics pre- and post-implementation to ensure high-performing, scalable solutions.
• Contribute to the technical vision and evolution of the application portfolio in partnership with leadership and senior technical resources.
• Other work and projects as assigned

What you need to have:

• Bachelors degree in Computer Science, Computer Engineering or a closely related course of study.
• 4+ years of enterprise Java development experience including full SDLC delivery and production support
• Hands-on Guidewire InsuranceNow experience (configuration and/or customization) on real delivery work
• Experience designing and implementing REST and SOAP APIs
• Experience with Java frameworks, JavaScript, jQuery, Velocity
• SQL and relational database experience
• Experience with AI-assisted development and the implementation of AI-based business solutions
• Demonstrated problem-solving across application, middleware, and infrastructure layers
• Strong communication skills and the ability to collaborate fluidly within technical teams and with business stakeholders
• Experience delivering in both Agile and Waterfall methodologies

What makes you stand out:

• Exceptional oral and written communication skills, a communication style flexible to the situation, and able to communicate clearly and with a purpose
• Calm under pressure. You have exceptional organizational skills, integrity, and great follow-through on tasks. You are comfortable challenging norms and recommending creative solutions
• A strong sense of accountability and ownership
• You are a master collaborator. Being able to bridge the gap between IT and business, to understand business priorities and system constraints will be one of your superpowers. 
• Natural curiosity, a love of learning how things work and always on the lookout for innovative improvements
