Key Responsibilities

Device Services Architecture: Architect, refactor, and build robust backend system services,

background workers, and Windows Services using .NET 8 / .NET Core and C# to manage complex

device lifecycles.

Peripheral & Hardware Integration: Integrate, maintain, and interface with vendor-specific SDKs,

native APIs, and drivers for physical hardware components (e.g., credit card processing terminals,

thermal printers, scanners, and sensory peripherals).

Low-Level System Communication: Author low-latency communication layers utilizing serial

protocols (RS-232/COM), USB, HID, TCP/IP sockets, and native system APIs (Win32/UWP APIs) to

communicate with device firmware.

Fault Tolerance & Reliability: Engineer fault-tolerant state machines, hardware error handling,

fallback logic, and automatic reconnection mechanisms to guarantee maximum operational uptime

in production environments.

System Refactoring & Modernization: Modularize and refactor monolithic device drivers and

legacy backend codebases into clean, decoupled, and testable service abstractions.





PCI & Compliance Standards: Ensure peripheral transactions and peripheral data flows adhere

strictly to security standards, PCI compliance, and hardware-level encryption protocols.

Required Qualifications & Technical Skills

Experience: 5+ years of qualified backend software engineering experience with C# and

the .NET ecosystem (.NET Core / .NET 8 / .NET Framework).

Hardware Integration Expertise: Demonstrated experience building software that interfaces with

physical hardware devices, external peripherals, or IoT devices via vendor-specific SDKs and APIs.

Low-Level & System Services: Deep technical background in authoring Windows Services,

background workers, multithreaded systems, and asynchronous messaging architectures.

I/O Protocols: Familiarity with hardware communication protocols and APIs (Serial/COM, USB,

HID, TCP/IP, Win32 APIs).

Code Quality & Testing: Proven track re
