Senior C++ Developer - Indexing Engine

Could your next optimization improve how millions of pieces of content become searchable? As a Senior C++ Developer on our indexing team, you'll help evolve the core technology powering Coveo’s indexing and search engine.

You'll work on large-scale systems where performance, scalability, and reliability matter every day, helping shape the technologies behind our AI-powered search experiences.

As one of our Senior C++ Developers, you will: .

• Design, develop, and optimize modern C++ code for Coveo’s indexing and search engine technologies.
• Improve the performance, scalability, and reliability of core indexing algorithms and infrastructure.
• 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.
