We are seeking an experienced software engineer to design, develop, test, and maintain enterprise-level web applications. The ideal candidate will have hands‑on experience building single‑page applications (SPAs) using Angular and Java/Spring, along with a strong understanding of object‑oriented programming and modern software development practices.

This position will work on moderately complex application development initiatives and may take a technical lead role on projects.

• Design, develop, implement, and maintain moderately complex application modules and subsystems.
• Develop enterprise-level web applications, including single‑page applications.
• Build and enhance applications using Java, Spring Framework, Angular, TypeScript, HTML5, and CSS.
• Investigate application defects, determine root causes, and develop effective solutions.
• Perform unit testing, integration testing, release testing, and other quality assurance activities.
• Research technical requirements and evaluate appropriate development approaches and technologies.
• Consider performance, target environments, and other technical requirements when designing solutions.
• Provide technical recommendations and communicate development approaches to project leadership.
• Lead development activities for assigned projects, including coordinating resources and managing multiple concurrent tasks.
• Identify and evaluate technical risks and develop contingency plans when necessary.
• Research and evaluate new technologies, frameworks, and development tools.
• Stay current with relevant technology, industry trends, and internal development standards.
• Participate in client meetings, presentations, technical demonstrations, and other customer‑facing activities.
• Provide technical guidance, training, and mentoring to junior team members.
• Work effectively within an Agile/Scrum development environment while managing competing priorities and maintaining a strong focus on quality.

Required Technical Skills

• Strong understanding of Object‑Oriented Programming (OOP) concepts and design patterns.
• Professional experience developing enterprise-level web applications.
• Hands‑on experience developing Java‑based web applications using the Spring Framework.
• Experience with Angular and TypeScript.
• Strong knowledge of HTML5 and CSS.
• Experience working with JSON and XML, particularly for data binding and data transfer.
• Ability to troubleshoot, analyze, and resolve complex application issues.
• Ability to manage multiple assignments in a fast‑paced Agile/Scrum environment.

Preferred Skills

• Experience with UI component libraries such as PrimeNG or similar three‑tier UI component libraries.
• Experience writing SQL queries.
• Experience working with PostgreSQL databases.
• Familiarity with Maven.
• Familiarity with Jenkins.
• Experience serving as a technical lead or project lead.
