Golang Software Engineer

Position: Golang Software Engineer

Location: Apex, NC (Hybrid)

Pay: $100,000 to $120,000 annually

Type: Full-time; Contract

Schedule: Monday - Friday

Greene Resources is seeking a Golang Software Engineer to join a growing and dynamic team! Our team builds the connected control platform at the

heart of Pentair’s pool automation ecosystem, orchestrating pumps, heaters, lights, valves, and salt chlorine generators through a modern Go-based middleware and gRPC API layer. You will work directly across several core codebases – a device orchestration middleware, a set of shared gRPC/protobuf API contracts, an embedded middleware application that runs on the controller hardware, and a protocol-bridging service that connects legacy clients to our newer API – helping us evolve a heterogeneous hardware control platform into a clean, well-tested, well-documented service architecture. We need someone who can move quickly in existing Go codebases, reason carefully about protocol and API design, and communicate clearly with a small, senior engineering team.

Job Description

• Design, build, and maintain Go services and libraries for device orchestration, binary encoding/decoding, and hardware transport abstraction (IP and serial-based communication).
• Contribute to an embedded middleware application that runs on the platform controller and coordinates hardware communication in real time.
• Extend and version a set of shared gRPC API contracts using Protocol Buffers and modern schema-management tooling, keeping multiple language consumers in sync.
• Work on a protocol-bridging service that connects a legacy JSON-based client protocol to a newer gRPC API, including protocol translation and conformance testing.
• Follow Google AIP-aligned API design conventions when adding or modifying gRPC services and messages.
• Write automated unit, integration, and conformance tests, and use GitHub Workflows for automated build, lint, and test pipelines.
• Participate in code and design reviews with the existing platform team, and help evolve device abstraction patterns for pumps, heaters, lights, and valves.
• Debug and resolve issues across the communication stack, from serial transport up through the gRPC API layer.
• Document architecture decisions, API changes, and operational runbooks to support cross-team collaboration.
  
  

Position Requirements

• 3 years of professional experience writing Go (Golang) in production systems; comfortable working in large, multi-package codebases.
• Practical experience with gRPC and Protocol Buffers, including schema design, versioning, and code generation (Buf or protoc).
• Familiarity with API design guidelines such as Google’s AIP standards, or a strong instinct for consistent, well-structured API contracts.
• Experience with device communication protocols and transport abstractions (e.g., serial/RS485, TCP/IP, or similar embedded I/O).
• Comfortable working in Linux/embedded Linux environments and Docker-based build systems.
• Solid testing discipline – unit tests, integration tests, and mock-driven or conformance-style test suites.
• Proficient with Git-based workflows and CI/CD pipelines (GitHub Actions or similar), including multi-repo coordination.
• Understanding of concurrent and networked systems design in Go (goroutines, channels, context cancellation).
• Communicates clearly in writing – PR descriptions, design docs, and code comments that a distributed team can follow.
• Comfortable working closely with a senior architect and firmware/hardware-adjacent teammates on cross-component issues.
• Values clean, modular architecture and is willing to refactor toward it, not just add new code on top of existing patterns.
• Reliable and self-directed – comfortable owning tickets end-to-end and reporting progress proactively.
  
  

Nice To Have

• Experience with WebSocket protocols or building protocol translation/bridging services between legacy and modern APIs.
• Background in IoT device management, home automation, or connected hardware products.
• Exposure to hardware communication protocols such as 802.15.4, Bluetooth, or other embedded RF/serial standards.
• Experience with workflow orchestration or event-driven architectures.
• Familiarity with firmware/bootloader concepts and OTA update strategies for embedded Linux devices.
• Prior experience in pool, HVAC, or other residential equipment automation is a plus, but not required.
