Lead Software Engineer, AI Driven Reliability & Support

The Mission

Financial advisors rely heavily on Morningstar's Direct Advisory Suite and when software breaks, they need instant resolution. Our Delight team transforms support from cost center into competitive advantage by combining hardcore production engineering with AI-enhanced diagnosis to deliver service excellence competitors can't replicate. You'll work on the hardest engineering problems (brownfield legacy systems at scale) while building AI tools that dramatically accelerate problem solving. You'll shape product strategy, not just fix bugs, proving that service excellence drives revenue and sustainable competitive advantage. This position requires working from the Chicago office Monday through Thursday.

This Role Is Ideal If You:

• Excel during production chaos and love being the "fixer" when systems start to fail
• View AI as a force multiplier for engineering work, not a replacement for deep technical knowledge
• Want your work to directly protect hundreds of millions in revenue
• Are energized by brownfield complexity that greenfield developers avoid
• Understands service excellence can be a durable competitive moat

What You'll Do

40-50%: Production Firefighting & Deep Troubleshooting

• Debug urgent production issues across 20+ years of legacy systems (C#, .NET, Python, SQL) with limited documentation and tightly coupled dependencies.
• Manually reproduce customer issues, isolate root causes, and deploy fixes under time pressure while partnering with L1/L2 support teams to resolve high-priority advisor tickets.
• Maintain uptime for mission-critical financial systems is nonnegotiable, requiring careful fixes that avoid downstream risk.

30-40%: Build the Diagnostic Flywheel

You will design and deploy AI agents that continuously improve detection, diagnosis, and resolution. This includes:

• Agentic and MCP powered tools that mine historical RCA to identify patterns.
• Systems that simulate issues, recommend fixes, automate workflows, and reduce dependency on manual troubleshooting.
• Evolving support from reactive (human driven fixes) to proactive (preventing issues before advisors notice).
• Your work will create compounding efficiency gains as the diagnostic flywheel learns and adapts.

10-20%: Strategic Engineering & Product Influence

You will convert recurring support insights into product intelligence, shaping roadmap priorities based on advisor pain points. You'll contribute PRs across the codebase, reinforcing a culture of shared ownership. You'll also mentor teammates on AI adoption while upholding production grade engineering standards.

Required Skills:

Production Engineering (Critical)

• 7+ years debugging enterprise production systems under pressure
• Expert troubleshooting across full stack: backend (C#, .NET Core), databases (SQL/NoSQL), AWS infrastructure
• Strong SQL skills for data investigation and manual fixes
• RESTful APIs, microservices, and distributed systems debugging

AI/Agentic Workflows (Growing Importance)

• Hands-on experience building LLM-powered tools (not copy pasting from ChatGPT)
• Understanding of Context engineering, prompt engineering, and other AI nuances
• Experience with agentic frameworks or MCP servers is a plus
• Python for automation and AI tooling

Cloud & DevOps

• AWS proficiency: ECS, Lambda, RDS, DynamoDB, CloudWatch, S3
• Infrastructure-as-code (Terraform, CloudFormation)
• CI/CD pipelines and modern deployment practices
• APM tools (DataDog, New Relic, etc.)

How the work gets done

• Empathy for advisors and support teams - you're solving real human pain, not abstract engineering problems
• Communication: explain technical issues to non-technical stakeholders
• Collaboration: work with L1/L2 support, product teams, and other engineering teams via shared ownership model
• Bias for action: ship fixes fast, learn fast, iterate
