At Sovos, we're dedicated to more than just solving compliance challenges -- we're committed to making a positive and lasting difference in everything we do. Our teams operate on the modern edge of digital technology, working not only to solve complex business challenges but also to enrich our personal, professional, and local communities.

Don't worry if you don't check all the boxes -- apply anyway! We're focused on hiring the right people, not just the "right" resume. It's not about what you've done elsewhere; it's all about what you're capable of doing here.

The Work You'll Do:

At Sovos, we're investing heavily in modernizing our STAT platform - the statutory reporting solution trusted by insurance companies navigating complex regulatory requirements across a rapidly evolving landscape. As a Senior Software Engineer, you'll serve as a technical authority and force multiplier for the team: setting direction, driving modernization, and leading our adoption of AI-assisted development practices. This isn't just about writing great code — it's about making the engineers around you better, and moving the entire team to a higher level of capability.

More specifically, you will:

• Serve as the technical authority for the STAT product, owning design decisions on the most complex features and integrations
• Lead architectural initiatives to decompose monolithic components into scalable, maintainable services
• Set and enforce code quality standards through proactive pull request reviews and design guidance
• Design for production realities — scalability, parallelization, and multithreading — not just functionality
• Collaborate with the Sovos Architecture team to align STAT's technical direction with global platform strategy
• Champion and actively use AI-assisted development tools (Cursor, GitHub Copilot, Devin) and help the broader team integrate them into daily workflows — from code generation and PR review to test coverage and defect management
• Customize and configure AI agents for STAT-specific workflows and establish team norms for responsible, effective AI use in a compliance-sensitive context
• Track and communicate the productivity and quality impact of AI adoption across the team
• Actively mentor engineers at all levels — finding teachable moments, delivering direct feedback, and investing in others' growth
• Take accountability for team outcomes: when the team is struggling, help diagnose it and rally people around a path forward
• Participate in sprint planning, design sessions, and roadmap discussions as a key voice on both technical quality and team capacity

What We Need From You

• 10+ years of software engineering experience with demonstrated principal or staff-level scope in recent roles
• Strong proficiency in C# /.NET and solid SQL Server skills including query optimization, schema design, and complex data models
• Experience with MVC patterns, WinForms, and React for modern front-end development
• Fluency with Azure DevOps for CI/CD, source control, and work management
• Demonstrated experience leading or contributing to monolith-to-services decomposition, with comfort in domain-driven design and API-first thinking
• Hands-on experience with AI coding tools (Cursor, GitHub Copilot, Devin, or comparable platforms) and a proven ability to help teams adopt and get measurable value from them — not just personal proficiency
• A genuine investment in the people around you — you measure your own success in part by how much better your teammates become
• Proactive communicator who raises flags early, keeps stakeholders informed, and connects cross-team dependencies before they become blockers
• Emotional maturity and self-awareness to handle ambiguity, conflict, and pressure without losing perspective
• Bachelor's degree in Computer Science, Engineering, or equivalent practical experience
• Experience in a SaaS product environment preferred
• Due to client contractual obligations, the successful candidate will be asked to clear a background check and drug test upon hire
