Remote Status: Hybrid

🚀 Role Summary

• Develop and maintain sophisticated web applications with a strong emphasis on User Interface (UI) design and architecture, utilizing modern frameworks like Angular 20+.

• Implement interfaces between applications, ensuring seamless communication through HTTP and RESTful services, with an understanding of API documentation tools like Swagger.

• Contribute to the conceptualization, design, and architecture of web applications, fostering code reusability and domain analysis.

• Test, debug, and refine software components, employing frameworks such as Playwright and Angular unit tests to ensure product integrity and efficiency.

• Enhance existing software and create new solutions to optimize operational time and improve overall system efficiency and integrity.

📝 Enhancement Note: While the title is "Web Software Developer (UI)", the responsibilities include both front-end (Angular) and back-end (NodeJs) development, as well as API integration and testing. This suggests a full-stack development role with a UI focus rather than purely front-end. The mention of "interfaces to applications" and "integrity between systems and applications" points towards a role involved in broader system integration and data flow management, which has strong parallels to Revenue Operations (RevOps) and Sales Operations (Sales Ops) in ensuring data integrity and process efficiency across the GTM tech stack.

📈 Primary Responsibilities

• Code and develop user interfaces and backend services using Angular 20+, NodeJs, NPM, RxJS, and associated libraries like Bootstrap and Material Design.

• Support the implementation of robust interfaces for various applications, leveraging knowledge of HTTP and RESTful communication protocols, and understanding API specifications through Swagger.

• Participate actively in the design phase of software tools and subsystems, focusing on creating reusable components and conducting domain analysis to inform architectural decisions.

• Test, debug, and fix software defects, ensuring the final product meets all specified requirements and performance benchmarks, with a particular focus on Playwright testing framework and Angular unit tests.

• Optimize and enhance existing software functionalities to reduce processing time, improve efficiency, and ensure seamless data integrity across interconnected systems and applications.

• Develop new software components and modify existing ones to maintain efficiency and ensure integrity between various systems and applications within the Amentum ecosystem.

• Contribute to the conceptualization, interface design, and overall architecture of web applications, ensuring a user-centric and scalable design.

• Explore and potentially integrate emerging technologies such as Claude or other AI interfaces to enhance application capabilities and user experience.

📝 Enhancement Note: The core responsibilities highlight a blend of front-end development, back-end services, API integration, and testing. For an operations professional, the emphasis on "integrity between systems and applications," "efficiency," and "support for implementation of interfaces" directly relates to the operational backbone of a company. This role requires a developer who understands how different systems interact and how to ensure smooth data flow and process execution, a critical aspect in RevOps and Sales Ops.
