Job Description

Apex Systems is hiring two Senior .NET Engineers to support POS modernization and feature development initiatives within a large, distributed engineering environment. This role is primarily backend-focused, with a strong emphasis on business flow logic, system integrations, and end-to-end application ownership.

This position may include limited direct people management, however the primary expectation is hands-on technical contribution. Ideal candidates are actively coding today and comfortable debugging production issues, reviewing system flows, and partnering closely with engineering teams to drive execution.

• Provide technical guidance and mentoring to engineers as needed
• Influence how teams execute work and improve system quality
• Collaborate with QA, SRE, and DevOps partner teams
• Support applications across the full software development lifecycle, including build, deployment, and long-term maintenance
  
  

Technical Environment

• Predominantly web-based systems, integrated with Android mobile platforms
• Multiple onshore and offshore agile teams operating independently
• SRE and DevOps teams engaged as partners rather than direct reports
  
  

Required Qualifications

• 7 years of professional software development experience
• Strong hands-on experience with .NET Core in production environments
• Proven experience owning applications across the entire SDLC
• Ability to troubleshoot and maintain complex, distributed systems
• Background in environments where developers are responsible for both building and maintaining software
  
  

Required Technical Skills

• .NET Core (primary focus)
• Oracle PL/SQL scripting and database lifecycle management
• JavaScript and Vue.js (integration awareness)
• Strong computer science fundamentals
• Understanding of HTTP/HTTPS, TLS handshakes, authentication, and token validation
• General knowledge of networking and infrastructure concepts
• Experience with unit and integration testing
• Familiarity with web-to-mobile integrations, specifically Android
