Go Systems Engineer

Job Title: Go Systems Engineer

Location: Pittsburgh, PA

Job Description:

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).
