Overview:

The Senior Software Development Engineer L4 is expected to successfully work through complex tasks independently, understand the intricacies of the software development life cycle, and display strong adherence to fundamental software engineering principles in the production of software. This position possesses a deep understanding of the computer's architectural design and other issues like testing and scalability of software products.

This role will contribute to the modernization of a high-impact, revenue-critical payer application that integrates with AI models to streamline clinical workflows and improve diagnostic accuracy for medical coders and staff. The engineer will work across the full stack using .NET, Angular, and AWS, contributing to both ongoing feature development and cloud migration efforts. This role is expected to operate with a high degree of independence once onboarded, and will collaborate closely with engineers across multiple levels of the team.

Duties and Responsibilities:

  • Work collaboratively to write high quality, testable code that meets the "Definition of Done" as it relates to team commitments;
  • Utilize a "Test-First" approach to software development, where possible, in which the test is developed before the code;
  • Participate in design and code reviews with other engineers;
  • Create automated unit, system and acceptance tests and participate in test plan reviews;

  • Write and maintain documentation to describe program development, logic, coding, testing, changes, and corrections;
  • Actively participate in the change management process as business and technical scope is adjusted;
  • Build and maintain full-stack features using .NET backend services and Angular frontend components, ensuring a high-quality, performant user experience;
  • Develop and maintain RESTful APIs and integrations that support clinical workflows and data exchange within the application;
  • Support cloud migration efforts, contributing to the transition of existing on-premise workloads toward AWS-based infrastructure;
  • Ask the right questions during grooming sessions to surface ambiguity early and ensure user stories are well-defined before development begins;
  • Develop a strong understanding of the healthcare domain and business context to contribute meaningfully beyond the immediate technical scope;
  • Mentor and coach junior engineers, providing guidance on code quality, architectural decisions, and engineering best practices;
  • Adhere to all confidentiality, HIPAA, regulatory, and other such policies, procedures, and requirements as outlined within Employer's Operating Policies and Procedures in all ways and at all times with respect to any aspect of the data handled or services rendered in the scope of work;
  • Maintain compliance with Inovalon's policies, procedures and mission statement, and fulfill those responsibilities and/or duties that may be reasonably provided by Inovalon for the purpose of achieving operational and financial success;
  • On Call Policy: Participate in an on-call rotation to support critical issues, including outside standard business hours (evenings, weekends, and holidays), ensuring timely response and resolution as per defined SLAs.

Job Requirements:

  • Minimum 6 years of software development experience, with demonstrated proficiency in C# and .NET; strong foundation in data structures and algorithms required;
  • 3 years of experience testing, maintaining, or launching software products, and 1 year of experience with software design and architecture;
  • Proficiency in Angular or comparable modern frontend framework, with the ability to build and maintain responsive, component-based UIs;
  • Experience with MS SQL Server or similar relational database technologies;
  • Experience with or demonstrated interest in cloud platforms, particularly AWS, in support of ongoing migration efforts;

  • Demonstrated high personal integrity and ability to earn trust from others;
  • Exhibits a growth mindset, seeks feedback often and is effective in continuous personal and professional development;
  • Continuously pursuing self-directed learning activities aimed at developing expertise within technical domain, including reading relevant publications, participating in domain forums or groups etc.;
  • Ability to anticipate and look for creative ways to solve problems and apply best practices;
  • Communication, organization, and teamwork skills.
