Staff Software Engineer (Rust)

Apollo Solutions; United States; Remote; USD 170,000 - 210,000; Full time

Job summary

Apollo Solutions is seeking a Staff Software Engineer to tackle hard systems problems at the intersection of Rust, compilers, performance engineering and LLM inference. This fully remote role involves building the performance-critical engine beneath a cutting-edge AI infrastructure.

You will own high-performance Rust systems, work on parsers, automata, grammars, indexes and data structures, and benchmark, debug and profile to keep systems blazing fast.

Qualifications

• Serious production Rust experience.
• Track record in high-performance, low-level or systems software.
• Excellent knowledge of data structures and algorithms.
• Experience with parsers, compilers, formal grammars, state machines, indexing/search or runtimes.
• Strong debugging, profiling and benchmarking skills.
• C/C++ or Python interoperability is a plus.
• AI experience is useful, but not essential.

Responsibilities

• Build and own high-performance Rust systems from design through production.
• Work on parsers, automata, grammars, indexes and sophisticated data structures.
• Profile and optimise code to be exceptionally fast.
• Integrate low-level systems into AI inference infrastructure.
• Rust engineering with opportunities to work near CUDA/GPU systems.
• Develop benchmarks and tooling to keep performance fast as technology evolves.
• Have genuine architectural influence in a small engineering team.

Job description

Staff Software Engineer, Rust | AI Infrastructure | Fully Remote

We're helping a rapidly growing AI infrastructure company hire a Staff Software Engineer to tackle some genuinely difficult systems problems at the intersection of Rust, compilers, performance engineering and LLM inference.

This is a small, highly technical team building critical infrastructure designed to make AI systems faster, more reliable and safe enough to operate in real-world production environments.

You'll work on the performance-critical engine underneath the product, where seemingly small improvements in algorithms, data structures and execution speed can have an enormous impact.

What you'll work on

• Build and own high-performance Rust systems from design through production
• Work on parsers, automata, grammars, indexes and sophisticated data structures
• Profile and optimise code that needs to be exceptionally fast
• Integrate low-level systems directly into modern AI inference infrastructure
• Rust engineering, with opportunities to get close to CUDA/GPU systems
• Develop benchmarks and tooling to make sure performance stays fast as the technology evolves
• Have genuine architectural influence in a small engineering team

We're interested in people with

• Serious production Rust experience
• A track record building high-performance, low-level or systems software
• Excellent knowledge of data structures and algorithms
• Experience with areas such as parsers, compilers, formal grammars, state machines, indexing/search or runtimes
• Strong debugging, profiling and benchmarking skills
• C/C++ or Python interoperability experience is a plus
• AI experience is useful, but absolutely not essential

Work on foundational AI infrastructure, not another application-layer AI wrapper

Deep Rust engineering, where performance and elegant computer science genuinely matter

Hard problems, spanning compilers, algorithms, inference and systems engineering

Early-stage impact, with substantial ownership over core technology

Fully remote, work from anywhere

If you're a strong systems engineer who's interested in applying low-level engineering skills to some of the hardest problems emerging in AI, I'd love to hear from you.
