• Work on low-level systems challenges involving memory management, concurrency, data structures, distributed processing, and high-throughput indexing.
• Analyze existing systems, identify bottlenecks, and implement improvements that make our engine faster and more efficient.
• Contribute to the architecture of new core indexing capabilities that support Coveo’s search and AI-powered experiences.
• Collaborate with engineering, data science, and product teams to transform complex search requirements into robust engine-level capabilities.

Here is what will qualify you for the role: 

• A minimum of about 5 years of experience in software development with C++, with familiarity with C++17 or newer as a strong asset.
• Strong experience building performant, reusable, scalable, and maintainable code in complex systems.
• A solid understanding of algorithms, data structures, concurrency, and systems-level performance considerations.
• Resourcefulness, a growth mindset, and a track record of solving complex technical problems.

What would make you stand out: 

• Experience building large-scale indexing, search, or information retrieval systems.
• Experience optimizing C++ applications for latency, throughput, or memory efficiency.
• Experience developing cloud-hosted distributed systems.
• Familiarity with vector search, AI-powered search, Elasticsearch, OpenSearch, Vespa, or similar technologies.
