We are looking for a talented, full stack Senior Software Engineer to drive technical execution and tackle complex challenges in our Insurance domain. This role requires a deep understanding of building scalable, modern applications while navigating the complexities of an industry with strict regulations, high data integrity requirements, and intricate workflows.

As a Senior Engineer, you will serve as a critical technical problem-solver- who takes extreme ownership of building scalable, highly reliable software systems in an agile environment. In this role, you will navigate the technical and regulatory complexities of insurance eligibility, claims processing, and remittance workflows. You will work closely with domain experts, product managers, and engineering peers to modernize legacy systems, design service-based architectures, and deliver high-impact software.

Success in this role is measured by your ability to evolve our core systems with a relentless focus on Business ROI and long-term technical health. Beyond writing exceptional code, you will champion the integration and adoption of AI tools, agentic workflows, and other efficiency drivers to fundamentally reshape how we develop software.

As a Senior Software Engineer your core responsibilities include:

• Design & System Evolution: Decompose complex business scenarios into clean, service-based architectures and distributed systems. Modernize legacy platforms with a focus on simplicity, maintainability, and long-term ROI.
• Domain Alignment: Translate complex insurance rules (claims, eligibility, remittance) into clean, high-performing technical solutions.
• Epic Ownership: Own the delivery of Epics end-to-end, actively managing risks, dependencies, and team-level DORA KPIs while ensuring system performance and delivery reliability.
• AI-Assisted Engineering: Champion responsible, AI-assisted development. Actively integrate AI tools (e.g., Claude, Git Hub Copilot) to automate design, test generation, and code reviews, and build agentic workflows to drive team efficiency.
• Software Design & Quality: Set rigorous standards for code quality through constructive code reviews, comprehensive automated testing (including AI-driven test suites), and continuous integration/delivery (CI/CD).
• Technical Leadership & Mentorship: Guide junior and mid-level engineers on software design patterns, debug cross-module issues, and act as a professional stakeholder manager who can navigate technical disagreements constructively ("disagree and commit").

• Backend Ecosystem: Strong, hands-on experience with the .NET Ecosystem (.NET Core / .NET Framework) and robust relational database design using SQL Server (including query optimization).
• Architecture & Design: Practical experience applying Domain-Driven Design (DDD) principles and building service-based or distributed architectures.
• Cloud & Dev Ops: Strong proficiency with AWS services (or other major cloud architectures), CI/CD pipelines and infrastructure provisioning.
• Batch & Data Processing: Familiarity with high-volume batch processing, background automated jobs, and handling complex data streams.

• Experience with Infrastructure as Code (IaC) using Terraform.
• Familiarity with event-driven architectures and system monitoring/APM tools (e.g., Datadog).
• Prior domain knowledge in orthodontic/dental billing, medical insurance, or healthcare fintech.
• Experience designing and querying APIs with GraphQL.
• Experience with search and analytics engines, specifically Elastic Search.

• Demonstrated experience or active experimentation leveraging modern AI coding assistants (e.g., Cursor, Claude, Git Hub Copilot) to optimize development velocity.
• Familiarity with Gen AI and Enterprise agentic workflows or utilizing Model Context Protocols (MCPs) to automate engineering workflows.
• Experience with automated testing frameworks (such as Playwright or equivalent) driven by AI agents.
