Senior Software Engineer

Overview

Lyric is an AI-first, platform-based healthcare technology company focused on simplifying the business of care by preventing inaccurate payments and reducing waste in the healthcare ecosystem. We are a market leader with 35 years of pre-pay editing expertise, and we are recognized for our achievements, including being named 2025 Best in KLAS for Pre-Payment Accuracy and Integrity, HI-TRUST and SOC2 certified, and a recipient of the 2025 CandE Award for Candidate Experience.

This role offers the opportunity to shape the future of healthcare with AI while contributing to a modernized payment integrity platform.

We are looking for a Full Stack Engineer to build intuitive, performant web experiences backed by scalable, event-driven services. You’ll own end-to-end delivery from modular frontend work to resilient microservices, collaborating with product, UX, Dev Ops, and QA to ship features  you thrive in fast-paced environments, value clean architecture and developer experience, and enjoy solving complex UI/UX and distributed systems challenges, this role is for you.

• Ship modernization work at a pace that surprises people.

• Use AI agents (Cursor, Claude Code, Codex) to drive framework upgrades, refactors, API extraction, test scaffolding, and documentation while catching hallucinations and preventing regressions before they reach a PR.

• Build reusable playbooks the team can actually follow: prompt templates, repo-level agent instructions, migration checklists, review heuristics, and clear definitions of done for AI-assisted changes.

• Collaborate with the team to measurably move the needle by migrating more modules per sprint and shortening PR turnaround times without increasing production bugs.

• Enhance the team’s quality through clearer PRs, increased test coverage, up-to-date documentation, and reduced repeated mistakes.

• Modernize a real .NET + SQL Server stack, upgrading legacy services to current .NET (LTS where appropriate) and clarifying architecture boundaries to address long-standing performance issues.

• Pursue a proper API-layer architecture – RESTful, versioned – built for correctness and maintainability, not just functionality.

• Work with SQL Server on query performance, indexing, and transactional correctness, including data pipeline work (e.g., Kafka) if needed.

• Own security and privacy by default, enforce least privilege, and ensure safe data handling in a healthcare context.

• Implement real quality guardrails: automated tests, CI that blocks bad changes, structured logging, and observability to inform decisions before users are affected.

• Review code thoughtfully, engage in honest architectural discussions, and raise the bar without unproductive conduct.

• Partner with analysts, stakeholders, and engineers to translate business problems into working software that delivers real value.

• Help build delivery plans that balance trade-offs and align with pragmatic milestones.

• 5+ years building and shipping production systems with real users, able to work independently and collaboratively in fast-moving teams.

• Some C# and modern .NET experience (Core and beyond), with participation in meaningful refactoring and migration in large codebases.

• Strong SQL Server capabilities including schema design, query tuning, and performance troubleshooting.

• Cloud experience with Azure and/or AWS;
  Azure experience is particularly relevant.

• API design experience with service-oriented architectures, versioning, authentication, reliability, and testing practices.

• Experience using AI coding tools (Cursor, Claude Code, Codex, or similar) daily, including multi-file refactors, migrations, test generation, and review workflows, with informed opinions on what works.

• Experience modernizing a legacy ASP.NET / .NET Framework codebase;
  Azure modernization patterns are a plus.

• Strong communication: clear PR descriptions, straightforward design docs, pragmatic collaboration, and low ego.

• Experience with distributed systems tooling (Kafka, event-driven architectures) and Postgres alongside SQL Server.

• Front-end experience with Angular and/or React/Next.js.

• Experience establishing agent-friendly engineering practices: writing repo instructions for AI tools, tasking AI-driven work, CI guardrails for AI-generated code, feature flags, canary deployments, and progressive delivery.

• Background in regulated domains (healthcare, fintech, payments) where speed must not compromise compliance.
