Systems Engineer

About the role

You’ll work on our Zig-based tools — flags.zig, tip, and new projects as they come up. The work is low-level: argument parsing, memory management, cryptographic primitives, and CLI interfaces. You’ll write code where correctness matters more than speed of delivery.

What you’ll do

• Extend and maintain flags.zig — comptime argument parsing, subcommands, error reporting
• Build new CLI tools in Zig for internal and public use
• Work on tip’s cryptographic layer — key derivation, memory zeroing, secure defaults
• Write tests that verify behavior at the byte level
• Review PRs from contributors with an eye for correctness and clarity

What we’re looking for

• Experience with systems programming — Zig, Rust, C, or C++
• Comfort with manual memory management and understanding of when it matters
• Familiarity with comptime/metaprogramming concepts
• Strong opinions about error handling, loosely held
• You’ve read code more than you’ve written it, and you think that’s a feature

Nice to have

• Contributions to open-source systems projects
• Experience with applied cryptography (not just theory)
• Familiarity with Zig’s standard library and build system
