Job Description

We’re hiring a Go Core Client Engineer. This remote role is for an engineer who will design, implement, and operate the Go-based shared client code that powers our product. You’ll work on core client subsystems: connection management, NAT traversal, control connection, encrypted transport, client lifecycle, and cross-platform runtime. You will be expected to ship end-to-end features, and improve reliability, performance, and observability.

Key Responsibilities

• Design, implement, test, and maintain core client features in Go: connection orchestration, reconnection strategies, NAT traversal, encrypted transport lifecycle, and sync logic.


• Ship end-to-end client work: design, implementation, launch, and observability (metrics, logs, traces).


• Diagnose and reduce client performance and reliability issues.


• Collaborate closely with product, per-platform clients, and platform teams.


• Champion engineering excellence by driving code quality, architectural reviews, and design documentation.


• Provide technical leadership and mentorship to other engineers, fostering a culture of learning and knowledge sharing.

What We Are Looking For

The list below captures the skills and experiences we use to evaluate candidates. A strong candidate will typically demonstrate a subset of those items. You don’t need to meet every bullet to be a good fit, and we consider the overall combination of skills, growth potential, and impact.

• Strong production experience writing and shipping Go code (experience with Go is required).


• Experience operating large Go codebases and designing robust client or distributed systems.


• Startup mindset: flexibility to adjust to changing priorities and thrive in an async, remote environment.


• Strong written and verbal communication and the ability to collaborate across product and engineering stakeholders

Nice to Have

• Experience with concurrency, performance tuning, and debugging.


• Solid networking and systems fundamentals: IP, routing, NATs, TCP/UDP, and TLS.


• Experience with P2P, WireGuard or similar encrypted transports and NAT traversal techniques.

• Connect with other Tailscalars IRL. Attend our annual company retreat, participate in team off-sites, and collaborate in person with teammates across Canada, the United States, and the United Kingdom. We support intentional in-person connection through team travel and distributed collaboration.
