Job description

NMI is looking for an experienced Senior Software Engineer (Full-Stack) to join our Fee Navigator team, part of our Account Management & Signup Tools value stream. FeeNavigator is a platform that automates merchant statement analysis and proposal generation — ingesting a processing statement in virtually any format, classifying every fee, computing markup and potential savings, and producing a signable proposal in seconds. It replaces work that previously took analysts hours per statement, and it sits at the heart of how our partners win and retain merchants.

This role is ideal for a seasoned engineer who can navigate complex systems, enjoys solving genuinely hard engineering challenges, and operates with a high degree of autonomy within a collaborative, agile team.

What will I be doing?

In this role, you’ll contribute across the full software development lifecycle — from planning and design through implementation, code review, testing, and deployment. You’ll work within a cross-functional team alongside Product and fellow engineers to deliver high-quality, secure software that powers our fee-analysis and proposal platform.

• Design, build, and enhance features within FeeNavigator using PHP/Laravel and Vue
• Develop efficient database queries and optimize MySQL performance as needed
• Own the quality of your work end-to-end through developer-led testing — writing unit, integration, and end-to-end tests, and validating your own changes through to production
• Improve the health of a large, established codebase by refactoring complex areas and decomposing high-complexity components into maintainable, well-structured code
• Document critical business logic, application workflows, and key architectural decisions
• Collaborate with Product Managers to refine requirements and contribute to technical solution design
• Participate in code reviews to maintain high engineering standards and share best practices
• Work with SRE to ensure software is observable, resilient, secure, and production-ready
• Diagnose and resolve incidents, defects, and performance bottlenecks in collaboration with cross-functional teams
• Contribute to continuous improvement of development processes, tooling, and engineering practices

Skills & Experience

Required

• Bachelor’s degree in Computer Science or equivalent experience
• 5+ years of experience developing complex applications
• Fluency in PHP and modern development practices
• Strong understanding of object-oriented programming and design patterns
• Experience with relational databases such as MySQL (schema design, query optimization)
• Experience with modern frontend development (JavaScript/TypeScript, Vue, npm, basic CSS/SCSS)
• Comfort working in large, established codebases — able to navigate unfamiliar systems, untangle complexity, and make sound changes with limited guidance
• Familiarity with secure coding principles
• Experience with Git and CI/CD workflows
• Experience contributing across the full SDLC
• Effective use of AI-assisted development tools, with the judgment to know where they add value and the discipline to review and validate their output
• Ability to work both independently and collaboratively

Preferred

• Strong experience with Laravel or similar modern PHP frameworks
• Experience with the Vue ecosystem (Quasar, Pinia, Vite)
• Experience with containerization technologies (Docker)
• Experience with caching technologies (Redis, Memcached)
• Experience with AWS services (ECS, ECR, S3, SQS)
• Experience working with logging & monitoring systems (e.g., Sentry, New Relic)
• Understanding of cloud-native or SaaS architectures (scalability, resilience, multitenancy)
• Exposure to Python and ML-adjacent services (Flask, Pandas, scikit-learn)
• Experience integrating AI capabilities into applications, or building workflows that incorporate them
• Track record of raising engineering standards on a team — improving test coverage, reducing technical debt, or modernizing legacy code

Benefits

• Competitive salary + bonus
• A remote first culture!
• Flex PTO
• Health, Dental and Vision Insurance
• 13 Paid Holidays

Salary range, depending on experience: $115,000 - $130,000 USD
