Position Summary

The Software Engineer III builds and extends the solutions our customers rely on, on top of our payment processing platform. This position works full stack — building APIs and services in C#/.NET on the backend, and features in Angular and/or React on the frontend — while acting as a technical point of contact for the platforms owned. This is a senior individual-contributor role with room to lead within a development team: setting technical direction on your projects, mentoring less experienced engineers, and shaping how the team builds software.

Duties & Responsibilities
  • Design and build full-stack features end to end — from API and data model through to the Angular/React UI that consumes it
  • Translate requirements from customers and product management into working solutions within our existing development frameworks and architecture
  • Act as subject-matter expert and point of contact for your assigned application platform(s), including direct interaction with customers when needed
  • Propose and drive architectural improvements to new and existing applications — you're expected to bring recommendations, not just implement others'
  • Identify opportunities to improve team process, tooling, and delivery practices, and help drive those changes
  • Write maintainable, well-tested code, applying SOLID principles and sound object-oriented/domain design
  • Participate in code reviews and mentor junior and mid-level engineers on both technique and judgment
  • Work within an Agile/Scrum process, including sprint planning, estimation, and — depending on the team — acting as a technical lead for the scrum team
  • Contribute to and maintain CI/CD pipelines in GitHub Actions
  • Design and build full-stack features end to end — from API and data model through to the Angular/React UI that consumes it

Education & Experience
Knowledge of:
  • Backend: C#, .NET (multiple versions/frameworks) advanced-level command, Microsoft SQL Server
  • Frontend: Angular and/or React
  • Infrastructure: Microsoft Azure, IIS, Azure function apps, Kubernetes microservices
  • Source Control / CI/CD: GitHub, GitHub Actions
  • Identity/Auth: Auth0
  • Tools: Visual Studio, Jira

Ability to:

  • Demonstrate advanced knowledge of technical concepts mentioned above
  • Use excellent written and oral communication skills
  • Demonstrate ability to cope with deadlines and pressure situations gracefully

Education and Training:

  • Bachelor’s Degree Preferred or equivalent practical experience
  • 4-6 years of professional software development experience, including full-stack work
  • Hands-on experience building production UIs in Angular and/or React
  • Solid experience with SQL Server as both a hosting platform and a development/query tool
  • Experience with Microsoft Azure and GitHub-based CI/CD pipelines
  • Demonstrated application of SOLID design principles and good coding craftsmanship
  • Comfort acting as a customer-facing technical point of contact
  • Demonstrate advanced knowledge of and experience with coding concepts mentioned above, ability to deliver high quality multi-tier application solutions
  • Experience leading scrum teams, mentoring other engineers, acting as customer point-of-contact and technical subject matter expert
  • Experience in payments, fintech, or another compliance-heavy domain preferred
  • Familiarity with Domain-Driven Design concepts preferred
  • Experience working across a distributed/global engineering team preferred
  • Experience with MongoDB preferred
