Sr Systems Engineers (Blockchain)

Location: Remote from Latin America; collaboration with protocol, cryptography, and product teams in San Francisco.

Company

hirify.global develops a blockchain-based financial infrastructure that unifies global markets and decentralized trading on a single execution platform.

What you will do

• Design and implement high-performance components in Rust, C++, or Go for the DEX engine and protocol runtime.
• Build low-latency pipelines for order execution, event propagation, and state updates.
• Optimize concurrency, scheduling, memory layout, and I/O for deterministic throughput.
• Collaborate with protocol engineers on safety, composability, and consensus compatibility.
• Profile, trace, benchmark, and resolve performance bottlenecks.
• Senior candidates will lead architecture decisions and mentor engineers.

Requirements

• Strong experience with Rust, C++, Go, or another systems programming language.
• Understanding of high-performance or distributed systems, runtimes, databases, or OS-level concurrency.
• Ability to reason about execution flows, concurrency models, resource lifecycles, and system invariants.
• Practical experience profiling CPU, memory, and synchronization overhead.
• Business English proficiency in spoken and written communication.
• Hiring levels include Junior with 1–3 years of experience and Senior with 5+ years of experience.

Nice to have

• Experience with matching engines, databases, compilers, blockchain runtimes, or HPC systems.
• Knowledge of lock-free concurrency, zero-copy data structures, or cache-aware design.
• Exposure to protocol engineering, consensus systems, transaction ordering, formal verification, or static analysis.
• Open-source contributions to systems-level projects.

Culture & Benefits

• Remote contract work within Latin America.
• Work directly on the execution backbone of a Layer 1 blockchain and next-generation DEX engine.
• Opportunity to grow into system ownership or lead execution architecture.
• High-performance engineering environment focused on correctness, reliability, and deep technical work.
