Golang Software Engineer

This contract role offers an opportunity for a mid-expert level Golang Software Engineer to join a platform engineering team responsible for the connected control platform at the core of a pool automation ecosystem. You will help orchestrate pumps, heaters, lights, valves, and salt chlorine generators through a modern Go-based middleware and gRPC services. The position focuses on evolving a heterogeneous hardware control platform into a clean, well-tested, and well-documented service architecture while collaborating closely with a small, experienced engineering team., * Develop, maintain, and enhance Go (Golang) services within large, multi-package codebases that power the pool automation control platform.

• Work directly across multiple core codebases, including a device orchestration middleware, shared gRPC/protobuf API contracts, an embedded middleware application running on controller hardware, and a protocol-bridging service connecting legacy clients to a newer API.
• Design, extend, and version shared gRPC and Protocol Buffers API contracts, ensuring compatibility, clarity, and long-term maintainability.
• Implement and refine protocol-bridging solutions that translate legacy interfaces into modern APIs, ensuring reliable communication between old and new systems.
• Collaborate with hardware and embedded teams to integrate serial/RS485, TCP/IP, and other embedded I/O transport abstractions into the platform.
• Work within embedded Linux environments and Docker-based build systems to build, deploy, and troubleshoot platform components.
• Write robust unit, integration, and conformance tests to ensure reliability, performance, and correctness of services and protocols.
• Leverage GitHub and CI/CD pipelines (such as GitHub Actions) to automate builds, tests, and deployments, maintaining a high standard of code quality.
• Reason carefully about protocol and API design, including schema evolution, versioning strategies, and backward compatibility.
• Collaborate closely with a small, experienced engineering team, communicating clearly about technical decisions, trade-offs, and implementation details.
• Contribute to improving documentation, coding standards, and best practices for the service architecture and platform components.
• Participate in troubleshooting and debugging efforts across the stack, including middleware, embedded applications, and protocol-bridging services., You will work as part of a focused platform engineering team that operates a modern Go-based middleware and gRPC ecosystem for pool automation control. The environment centers on embedded Linux systems, Docker-based build pipelines, and GitHub-driven workflows with CI/CD automation. You will collaborate closely with experienced engineers in a setting that values clear communication, careful API and protocol design, and strong testing practices. The role involves working with hardware-adjacent technologies such as serial/RS485, TCP/IP, and embedded I/O, providing exposure to connected devices and automation systems

• 3+ years of production experience with Go (Golang) in large, multi-package codebases, including hands-on use of goroutines, channels, and context cancellation.
• Practical, hands-on experience with gRPC and Protocol Buffers, including schema design, versioning, and code generation using tools such as Buf or protoc.
• Direct experience with hardware and serial communication protocols, such as serial/RS485 and TCP/IP, or similar embedded I/O transport abstractions.
• Comfort working in Linux and embedded Linux environments, including experience with Docker-based build systems.
• Strong testing discipline with proven experience writing unit, integration, and conformance tests.
• Proficiency with GitHub and CI/CD pipelines, such as GitHub Actions or similar tools, to support automated build, test, and deployment workflows.
• Ability to move quickly and confidently within existing Go codebases while maintaining code quality and reliability.
• Strong communication skills and the ability to collaborate effectively within a small, experienced engineering team.

Additional Skills & Qualifications

• Experience with WebSocket protocols or legacy-to-modern API protocol bridging.
• IoT device management, home automation, or connected hardware products.
• Familiarity with embedded RF and serial standards such as 802.15.4, Bluetooth, or similar technologies.
• Exposure to workflow orchestration or event-driven architecture patterns.
• Understanding of firmware and bootloader concepts, including over-the-air (OTA) update strategies for embedded Linux devices., Individual compensation offered for this position within this range will depend on many factors, including qualifications, skills, relevant experience, job knowledge, geographic location, internal equity, and other pertinent job-related factors.
