MaintainX is a leading mobile-first work execution platform for industrial and frontline teams, serving over 13,000 customers, including Duracell, McDonald's, Shell, DHL, and Volvo. It manages 13.9 million assets and 79.5 million completed work orders, helping reduce unplanned downtime and optimize operations.

In August 2026, MaintainX became part of Autodesk Operations Solutions, unifying Autodesk’s operations platform alongside Tandem, FlexSim, and Fusion Operations. Autodesk’s strategy focuses on converging design, manufacturing, and operations into a continuous lifecycle, with MaintainX leading the operate phase.

What You'll Do:

• Design and build MaintainX’s end-to-end search and retrieval platform, covering indexing pipelines, ranking systems, and AI-facing query layers.

• Collaborate with product and domain experts to model search across core entities like work orders, assets, and procedures, ensuring high-relevance results.

• Adopt an agile approach: ship fast, iterate quickly, launch early versions, gather feedback, and improve rapidly.

• Operate and optimize distributed systems for 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.

• Handle on-call duties (currently during 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 like Elasticsearch, OpenSearch, Lucene, or Solr.

• 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.

• Expert-level English for leading platform engineering managers, presenting technical priorities to executives, and aligning with engineering leaders globally.

Nice to Have:

• Experience evaluating and improving search relevance using qualitative and quantitative metrics.

• Experience shipping AI-powered or LLM-integrated backend systems.

• Familiarity with 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.

MaintainX’s mission is to keep the physical world running by providing tools for factories, fleets, hospitals, and campuses.
