Software Engineer III

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.

• 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 Git Hub Actions

• 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:
  Git Hub, Git Hub Actions
• Identity/Auth:

• Tools:
  Visual Studio, Jira

• 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

• 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 Git Hub-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
