What You'll Do:- Design and build MaintainX's end-to-end search and retrieval platform - from indexing pipelines and ranking systems to AI-facing query layers.
- Partner with product and domain experts to model search across core entities like work orders, assets, and procedures, ensuring high-relevance results.
- Ship fast, iterate fast, launch early versions, gather feedback, and improve rapidly.
- Operate and optimize distributed systems, ensuring reliability, performance, and scalability under real-world load.
- Drive architectural decisions, balancing correctness, performance, and long-term maintainability.
- Own integrations between search systems and upstream data sources.
- Explore semantic search, vector retrieval, and AI-enhanced relevance using modern ML tooling.
- On-call duties (currently business hours)
About You:- Hands-on experience designing, building, and operating production-grade search systems end-to-end - including indexing, query execution, relevance tuning, and infrastructure - using technologies such as Elasticsearch, OpenSearch, Lucene, Solr, or similar.
- Understanding of embeddings, chunking, and retrieval strategies.
- Familiarity with search-specific tuning: analyzers, BM25, shard sizing, cluster health, and relevance optimization.
- Comfort taking systems from implementation to deployment and production operation, working across backend services, data pipelines, and integration points as needed.
- An expert level of English, both spoken and written, is required, as the individual will need to lead platform engineering managers across multiple teams, present technical priorities to executive stakeholders, and align with engineering leaders outside Québec on a daily basis.
Nice to Have:- Experience evaluating and improving search relevance using both qualitative analysis and quantitative metrics.
- Experience shipping AI-powered or LLM-integrated backend systems
- Comfortable using modern AI tools like GPT, Copilot, or Cursor to boost productivity and streamline development.
- Understanding of multi-tenancy and data security, including ACLs, field-level access controls, and secure index partitioning.
- Experience building observability and success metrics into systems to monitor performance, usage, and impact.
What's in it for you:- Competitive salary and meaningful equity opportunities.
- Healthcare, dental, and vision coverage.
- 401(k) / RRSP enrollment program.
- Take what you need PTO.
- A Work Culture where:
- You'll work alongside folks across the globe that reflect the MaintainX values: Smart Humble Optimists.
- We believe in meritocracy, where ideas and effort are publicly celebrated.
Our mission is to keep the physical world running. Factories, fleets, hospitals and campuses stay up because the people who maintain them have tools worth using. That is what we build.
