About the role

Aplyr's Quick Take

This role is for a Senior or Expert Systems Engineer focused on developing core components for a search engine. You'll be designing and building systems that handle large-scale data processing and optimizing performance at a low level. It's an individual contributor position that requires deep technical expertise in systems programming and search technologies.

Good fit

Ideal candidates have 3+ years of experience in systems programming, particularly in languages like Rust or C++. You should be comfortable with full project lifecycles and have a strong grasp of algorithms, data structures, and multithreading.

Worth noting

The role emphasizes low-level optimizations and performance tuning, which may not be typical for all search engine development positions. The focus on high-load environments and hardware performance could be a red flag for those not comfortable with complex systems.

Perplexity is looking for a highly skilled Senior or Expert Systems Engineer to join our Search Core team. This role is critical to building next-generation search products and technologies. You will help drive key decisions around the architecture, design, and implementation of foundational components in our technical stack.

Responsibilities

Design and build core search engine components, including indexing pipelines, retrieval algorithms, and ranking systems that operate at the scale of billions of pages
Develop streaming and batch data processing systems for search index construction in a high-load environment
Push the limits of hardware performance through low-level optimizations and systems-level tuning
Tackle challenges in multithreading, concurrency, and system-level optimization

Qualifications

3+ years of hands-on experience in systems programming (Rust, C++, C, or similar)
Ownership of full project lifecycle — you don't just write a fast inner loop, you care about how the system is built, deployed, operated, and scaled in production
Knowledge of Python or other scripting languages
Passion for writing clean, efficient, and scalable systems-level code
Strong knowledge of algorithms and data structures, and the ability to apply them effectively
Deep understanding of multithreading, including various approaches, challenges, and trade-offs
Experience building high-load, distributed, and hardware-adjacent services
Solid understanding of Linux internals (syscalls, networking stack, memory model, kernel tuning)
Familiarity with low-level optimization techniques (memory management, cache efficiency, SIMD, profiling)

Preferred Qualifications

Experience developing core components of search engines, databases, or information retrieval systems
Understanding of search fundamentals: indexing, query parsing, ranking, and relevance
Experience with trading systems or other latency-sensitive real-time systems
Familiarity with cloud services, Kubernetes, and AWS infrastructure
