Position Summary

The Senior Software Engineer leads the design, development, and deployment of complex software solutions, ensuring scalability and maintainability. This role architects and implements high-performance APIs and microservices that support critical business functions, and works closely with product managers, UX designers, and other engineers to translate business needs into technical solutions.

Evolent engineers are expected to effectively leverage approved AI-assisted development and productivity tools (e.g., code assistants, copilots, automation agents, knowledge assistants, and analytics tools) to improve quality, efficiency, and innovation while maintaining accountability for all delivered work. These expectations span the full engineering lifecycle, not only code generation, including iterating with AI on solution design and architecture, evaluating alternatives, revising existing architecture, and producing design artifacts. Engineers remain responsible for validating outputs, ensuring solution quality, protecting sensitive information, and complying with security, privacy, regulatory, and Responsible AI standards.

Identify and implement improvements to the software development lifecycle, including automation, testing, and CI/CD pipelines.
Troubleshoot and resolve production issues, working to ensure high availability and reliability of services.
Evaluate and integrate new tools, frameworks, and technologies to improve development processes and team productivity.

AI-Enabled Delivery

Utilize approved AI-assisted engineering tools to accelerate software development, testing, documentation, troubleshooting, and analysis activities.
Apply AI-assisted development techniques throughout the software development lifecycle, including requirements analysis, coding, testing, debugging, documentation, and operational support.
Evaluate and validate AI-generated outputs for correctness, security, maintainability, compliance, and business appropriateness.
Continuously identify opportunities to improve engineering productivity and solution quality through AI-enabled workflows and automation.
Contribute reusable prompts, skills, agents, and AI-assisted development patterns to benefit the team.
Partner with architecture, security, and platform teams to integrate AI-enabled capabilities into enterprise applications.

Governance and Compliance

Follow enterprise policies governing AI usage, intellectual property protection, security, privacy, PHI handling, and Responsible AI practices.
Ensure no confidential, regulated, or protected information is used with unapproved AI services or tooling.
Participate in peer reviews and validation processes for AI-assisted solutions.

Required Qualifications

5+ years of professional software development experience, with a proven track record of delivering complex, scalable applications.
Proficiency in multiple programming languages, such as C#, Java, or Python, and familiarity with their ecosystems.
5+ years of hands-on experience with Microsoft and .NET technologies, specifically .NET Core, C#, and T-SQL.
Experience building scalable and performant RESTful APIs using ASP.NET.
Relational database development experience, preferably using SQL Server.
Experience with at least one testing framework (e.g., xUnit, NUnit, MSTest), logging framework (e.g., NLog, log4net, Serilog), and ORM framework (e.g., Dapper, Entity Framework, NHibernate).
Deep understanding of software architecture patterns, such as microservices, event-driven architecture, and RESTful API design.
Strong knowledge of cloud computing platforms (e.g., Azure, AWS, Google Cloud) and container orchestration tools such as Docker and Kubernetes.
Expertise in database design and optimization for both SQL and NoSQL databases.
Experience using GitHub, Azure Git, or other Git-based source control systems, including working with pull requests.
Ability to work both independently and as part of a globally distributed team of technical and non-technical colleagues.
Excellent problem-solving skills, with the ability to diagnose and resolve complex technical issues quickly.
Strong communication skills, with the ability to lead technical discussions, present to stakeholders, and write detailed documentation.

Preferred Qualifications

Experience using AI-assisted development platforms such as GitHub Copilot, Cursor, Claude Code, or similar tools.
Familiarity with prompt engineering, AI-assisted testing, and AI-enabled software delivery practices.
Experience integrating AI services, models, or agents into production applications.
Experience with front-end frameworks (e.g., React, Angular, Vue), including developing Single Page Applications (SPA).
Experience with additional back-end technologies (e.g., Node.js, Django, Spring Boot).
Experience with EMR integration.
Experience working with NoSQL data stores (e.g., Elasticsearch).
Healthcare domain experience.

Education

Bachelor’s or Master’s degree in Computer Science, Software Engineering, or a related field, or equivalent practical experience.
