Key Responsibilities
- Backend Service Development: Build, update, and maintain backend services, background tasks,
and Windows Services using .NET 8 / .NET Core and C#.
- Hardware & Peripheral Integration: Assist in integrating vendor-specific SDKs, native driver APIs,
and hardware libraries to communicate with physical peripherals.
- System Refactoring: Refactor legacy backend components into modular, maintainable, and
testable service abstractions.
- Error Handling & State Logic: Implement robust state management, exception handling, and
recovery routines for physical device operations.
- Code Quality & Testing: Write unit tests for hardware abstraction layers, participate in peer code
reviews, and support automated test pipelines.
- Agile Collaboration: Participate in daily standups, technical estimation sessions, and sprint
planning within a collaborative engineering environment.
Required Qualifications & Technical Skills
- Experience: 3+ years of professional backend development experience with C# and the .NET
ecosystem (.NET Core / .NET 8 / .NET Framework).
- Hardware Integration: Previous experience or strong interest in interfacing software with physical
devices, hardware peripherals, or external APIs/SDKs.
- Backend Fundamentals: Solid understanding of multithreading, asynchronous programming
(async/await), dependency injection, and RESTful API architecture.
- Database & Tooling: Working knowledge of SQL Server, version control with Git, and debugging
tools within Visual Studio.
Core Competencies & Cultural Fit
- Self-Motivated Learner: Eager to expand technical skills, adapt to hybrid tech stacks, and learn
from senior engineers.
- Strong Individual Contributor: Able to take assigned tasks, ask the right clarifying questions, and
execute independently with minimal oversight.
- Reliable Team Player: Values collaboration, open communication, and constructive feedback
during code reviews.
- Remote-Ready Communicator: Clear, prompt communication across chat tools (Slack, Teams)
and project tracking systems (Jira, Azure DevOps).
Preferred / "Nice-to-Have" Qualifications
- Practical experience working with Point-of-Sale (POS) hardware, payment processing peripherals,
or self-service terminal systems.
-
Exposure to serial communication (RS-232/COM), USB, or socket-based networking protocols.
-
Familiarity with PCI compliance principles or secure data handling standards.
-
AI-Driven Productivity: Experience leveraging AI-assisted development tools (e.g., GitHub Copilot,
Cursor, Claude Code) to write unit tests, generate mock peripheral interfaces, and debug backend
logic faster.
