Senior Application Modernization Engineer

About the role

We're looking for AI-enabled Application Modernization Engineers passionate about modernizing legacy software, building cloud-native and AI-augmented systems, and helping both client teams and our own engineers improve quality and speed of delivery. You will act as both a builder and an enabler — writing production-grade code and uplifting the engineers around you on modern AI-augmented ways of working.

What You'll Do

• Built production applications from scratch and modernized legacy systems — comfortable with both greenfield and brownfield, and know when approaches like strangler fig or lift-and-refactor are appropriate
• Fluent in multiple programming languages and paradigms — clean, testable code in both functional and object-oriented styles, knowing how to pick the right tool for the job
• Delivered full-stack solutions — frontend web apps, backend APIs, cloud-hosted services, and standalone applications — and understand how those pieces fit together end-to-end in complex enterprise environments
• Worked inside large enterprise environments with distributed systems and multi-cloud setups — you know how to navigate organizational complexity and deliver in spite of it
• Own your part of the SDLC end-to-end — writing code, reviewing PRs, writing tests, and empathizing with developers on either side of you
• Understand cloud-native architecture — containerization, microservices, event-driven patterns — and are comfortable with source control branching strategies and CI/CD automation
• Built or been closely embedded with Operations teams — you understand cloud-native platform adoption, whether that's Kubernetes, managed container services, or other orchestration platforms depending on client environment, infrastructure as code, observability, and what it means to build software that can actually be run in production
• Built or integrated AI capabilities into real applications — you know what it takes to get an LLM-powered feature into production and keep it working
• Use AI coding tools like Claude, Cursor, or Windsurf as a natural part of how you work — as a way to move faster and produce higher quality output every day
• Familiarity with retrieval-augmented generation, vector databases, or semantic search — either from building it or working alongside someone who has

Requirements

• 5+ years of hands-on software engineering experience
• Must be authorized to work in the United States or Canada without sponsorship
• Travel availability: 25-50% depending on client needs

Specifics

• Full benefits including unlimited PTO, funded HSA option, 401k match, monthly LiveWell stipend, and quarterly company bonus
• Annual base salary: $120,000-170,000 depending on experience
• Liatrio is an equal opportunity employer. We value diversity at our company and strive to create a culture of inclusion.
