Go developer (with NATS Experience Preferred) - Part-time - NA/LATAM/EU

About the Project

We're working with Phil Harley on a client-server proof of concept project that requires a skilled Go developer, ideally with experience using NATS for communication between distributed systems. The goal is to build a secure system where a client application - running behind a firewall on Windows or Linux - executes SQL queries locally and communicates results to a cloud-based server via NATS.

This role is ideal for a mid-level backend developer who enjoys working in a focused, low-meeting, high-autonomy environment with modern, performant technologies.

Key Responsibilities

• Build and maintain a Go-based client-server communication system
• Implement NATS (or similar messaging middleware) for secure, real-time messaging
• Develop the client component to run SQL queries on a local database
• Develop the server component to receive, store, or process data sent from client
• Ensure compatibility with both Windows and Linux client environments
• Collaborate with the project lead asynchronously and report progress weekly

Requirements

• 4–5 years of experience with Go (Golang) in production environments
• Experience with NATS (highly preferred), or similar messaging technologies (e.g., MQTT, RabbitMQ)
• Comfortable building binaries for deployment across Windows and Linux systems
• Strong understanding of client-server architecture and distributed systems
• Experience with SQL databases and query execution
• Fluent English communication—written and spoken
• Available to work ~20 hours/week with flexible scheduling

Nice-to-Haves

• Prior experience with secure messaging across firewalls
• Familiarity with cloud-based infrastructure (AWS, GCP, etc.)
• Experience working with early-stage or proof-of-concept projects
• Previous work on real-time data systems or distributed applications
