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 professional 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 record of writing unit/integration tests for hardware

abstraction layers, leveraging dependency injection, and using Git-based CI/CD workflows.

Core Competencies Cultural Fit

Self-Motivated Learner: Eager to dive deep into unfamiliar hardware SDKs, vendor documentation,

and low-level system protocols to solve complex technical problems.

Strong Individual Contributor: Able to take ownership of end-to-end device integration pipelines,

troubleshoot physical/hardware edge cases, and execute independently with minimal supervision.

Reliable Team Player: Values transparent communication and collaborates effectively with

backend architects, QA teams, and technical operations.

Remote-Ready Communicator: Explicit, prompt, and detailed technical communication across

asynchronous tools (Slack, Teams) and task tracking platforms (Jira, Azure DevOps).

Preferred / "Nice-to-Have" Qualifications

Experience with POS (Point of Sale) systems, payment terminal integration (PCI-DSS compliance,

EMV processing), or self-service terminal/kiosk architectures.

Familiarity with C/C++ interop (P/Invoke) or native C-DLL wrappers within .NET applications.

Understanding of diagnostic logging, telemetry, and remote hardware monitoring frameworks.

AI-Assisted Development: Proficiency in utilizing AI-driven tools (e.g., GitHub Copilot, Cursor,

Claude Code) to analyze legacy drivers, mock peripheral interfaces for testing, and accelerate

development.
