Senior Software Engineer, Full Stack (Agentic)

MHC is a global provider of AI-powered SaaS solutions for document, communication, and payment automation serving highly regulated industries. The Senior Software Engineer will design, build, and ship full-stack features across .NET backend services, APIs, data access, and modern web front-ends while using AI coding agents to plan, implement, test, and review software. The role also owns architecture, quality, collaboration, mentoring, and advancing an agentic-first engineering culture.

Responsibilities:

• Design and ship features end to end, backend services and APIs (preferably .NET / C#), data access, and modern web front-ends (e.g. Vue, React/TypeScript)
• Own architecture and technical design for the features and services you lead, balancing speed, scalability, and maintainability
• Write clean, well-tested, observable code and uphold strong engineering practices: comprehensive testing, code review, CI/CD, and operational excellence
• Use AI coding agents (e.g., Claude Code and similar tools) as a core part of your daily workflow to plan, implement, test, refactor, and review software
• Break complex work into clear, well-scoped tasks and write the specs, context, and guardrails that let agents produce high-quality results
• Rigorously review, test, and harden agent-generated code — you remain accountable for correctness, security, and quality
• Improve how the whole team works with agents: share patterns, build reusable prompts/tooling, and raise the team's agentic-engineering maturity
• Partner with Product, Design, and other engineers to turn ambiguous problems into shipped, customer-facing value
• Mentor peers, contribute to technical direction, and help establish standards for an agentic-first engineering culture

Requirements:

• Hands-on experience building software with an agentic engineering approach — using AI coding agents/assistants (e.g., Claude Code, Copilot, Cursor, or similar) to plan, implement, and review real production work, not just autocomplete
• Strong fundamentals in system design, data modeling, APIs, relational databases (e.g., SQL Server/PostgreSQL), testing, and CI/CD
• Cloud experience (Azure, AWS, or GCP) and comfort with modern delivery practices (containers, automated pipelines, observability)
• Excellent judgment and code-review skills — able to critically evaluate and harden AI-generated code for correctness, security, and performance
• Clear communicator who can decompose ambiguous problems and collaborate effectively across a distributed, remote team
• 5+ years of professional software engineering experience building and shipping production full-stack applications
• Bachelor's degree in Computer Science, Engineering, or a related field required; equivalent practical experience considered
• This role is not eligible for visa sponsorship
• Experience writing prompts, custom agent tooling, MCP servers, or agentic workflows; familiarity with LLM APIs (OpenAI, Anthropic) and RAG
• Background in B2B SaaS, document/process automation, or other data- and workflow-heavy enterprise domains
• Familiarity with security and compliance in multi-tenant SaaS (e.g., SOC 2)
• Open-source contributions or a track record of raising engineering practices on a team
• candidates who currently reside in or near the area are preferred
