Go Systems Engineer

Key Responsibilities

Design and optimize low-level systems in Go, focusing on performance, concurrency, and
safety.
Author or contribute to compiler, runtime modules, or garbage collector in Go.
Build and maintain production-grade Raft or Paxos implementations.
Develop lock-free and wait-free algorithms for high-throughput systems.
Engineer custom RPC protocols or messaging buses beyond standard frameworks.
Deliver code that runs without OS dependencies, libc, or dynamic memory allocation.
Design and implement bytecode VMs, memory-safe networking stacks, or kernel
modules using Go and cgo.
Work in sandboxed, air-gapped, and no-stdlib environments.
Trace syscalls from Go code through hardware interrupts to ensure deterministic
behavior.

Required Qualifications
8 10 years of experience in low-level systems programming.
6 8 years of production experience with Go as the primary language.
Demonstrated experience with consensus protocols (Raft, Paxos).
Strong expertise in concurrency, memory models, and system safety guarantees.
Proven ability to work in constrained environments (no OS/no dynamic allocation).
Experience with syscalls, atomic operations, and advanced synchronization mechanisms.
Hands-on experience implementing a custom Go scheduler.
Expertise in memory-mapped IO, real-time kernel patches, and hardware-level profiling
tools (perf, BPF, VTune).
Maintainer or contributor to high-impact open-source projects (Kubernetes, Etcd,
container runtimes).
Deep familiarity with Go compiler internals (escape analysis, memory allocation
behavior).
