Responsibilities\nDevice Services Architecture: Architect, refactor, and build robust backend system services,\nbackground workers, and Windows Services using .NET 8 / .NET Core and C# to manage complex\ndevice lifecycles.\nPeripheral & Hardware Integration: Integrate, maintain, and interface with vendor-specific SDKs,\nnative APIs, and drivers for physical hardware components (e.g., credit card processing terminals,\nthermal printers, scanners, and sensory peripherals).\nLow-Level System Communication: Author low-latency communication layers utilizing serial\nprotocols (RS-232/COM), USB, HID, TCP/IP sockets, and native system APIs (Win32/UWP APIs) to\ncommunicate with device firmware.\nFault Tolerance & Reliability: Engineer fault-tolerant state machines, hardware error handling,\nfallback logic, and automatic reconnection mechanisms to guarantee maximum operational uptime\nin production environments.\nSystem Refactoring & Modernization: Modularize and refactor monolithic device drivers and\nlegacy backend codebases into clean, decoupled, and testable service abstractions.\nPCI & Compliance Standards: Ensure peripheral transactions and peripheral data flows adhere\nstrictly to security standards, PCI compliance, and hardware-level encryption protocols.\nRequired Qualifications & Technical Skills\nExperience: 5+ years of professional backend software engineering experience with C# and\nthe .NET ecosystem (.NET Core / .NET 8 / .NET Framework).\nHardware Integration Expertise: Demonstrated experience building software that interfaces with\nphysical hardware devices, external peripherals, or IoT devices via vendor-specific SDKs and APIs.\nLow-Level & System Services: Deep technical background in authoring Windows Services,\nbackground workers, multithreaded systems, and asynchronous messaging architectures.\nI/O Protocols: Familiarity with hardware communication protocols and APIs (Serial/COM, USB,\nHID, TCP/IP, Win32 APIs).\nCode Quality & Testing: Proven track record of writing unit/integration tests for hardware\nabstraction layers, leveraging dependency injection, and using Git-based CI/CD workflows.\nCore Competencies & Cultural Fit\nSelf-Motivated Learner: Eager to dive deep into unfamiliar hardware SDKs, vendor documentation,\nand low-level system protocols to solve complex technical problems.\nStrong Individual Contributor: Able to take ownership of end-to-end device integration pipelines,\ntroubleshoot physical/hardware edge cases, and execute independently with minimal supervision.\nReliable Team Player: Values transparent communication and collaborates effectively with\nbackend architects, QA teams, and technical operations.\nRemote-Ready Communicator: Clear, prompt, and detailed technical communication across\nasynchronous tools (Slack, Teams) and task tracking platforms (Jira, Azure DevOps).\nPreferred / \"Nice-to-Have\" Qualifications\nExperience with POS (Point of Sale) systems, payment terminal integration (PCI-DSS compliance,\nEMV processing), or self-service terminal/kiosk architectures.\nFamiliarity with C/C++ interop (P/Invoke) or native C-DLL wrappers within .NET applications.\nUnderstanding of diagnostic logging, telemetry, and remote hardware monitoring frameworks.\nAI-Assisted Development: Proficiency in utilizing AI-driven tools (e.g., GitHub Copilot, Cursor,\nClaude Code) to analyze legacy drivers, mock peripheral interfaces for testing, and accelerate\ndevelopment.","description_format":"text","description_chars":3409,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-10-18T10:51:57Z"}],"visa":[],"liveness":{"score":13,"band":"cold","label":"Long
