Job description

MaintainX is the world leading mobile-first workflow management platform for industrial and frontline workers. We are a modern IoT enabled cloud based tool for maintenance, safety, and operations on equipment and facilities. MaintainX powers operational excellence for 10,000+ businesses including Duracell, Univar Solutions Inc., Titan America, McDonalds, Brenntag, Cintas, Michaels, and Shell.

We've raised $104 million in venture capital following a recent Series C funding round led by Bain Capital Ventures, Bessemer Ventures, August Capital, Amity Ventures, Ridge Ventures as well as CEO’s from GE, Twilio, Toast and PagerDuty.

We want MaintainX to be the go-to work execution platform for manufacturers across Maintenance, Operations, and Safety. To do that, we’re forming a new Search Engineering Team to build world-class indexing and retrieval systems that power discovery across the platform.

About the Role

We’re starting a brand-new Search team to make it easier for users find exactly what they need across MaintainX. As one of the first engineers on this team, you’ll play a critical role in designing, building, and scaling search infrastructure that reflects the unique shape of the MaintainX domain.

This is a zero-to-one role. You’ll be scoping ambiguity, shipping usable search early, and evolving it with fast feedback loops. If you enjoy building systems from scratch, obsess over performance and relevance, and want your work to power daily decisions across industries, we’d love to talk.

What you’ll do:

• Design and implement search infrastructure from the ground up, indexing pipelines, query layers, ranking systems, and more.
• Collaborate with product and domain experts to model search around core MaintainX entities like work orders, assets, and procedures.
• 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.
• (Optional but valued) Explore semantic search, vector retrieval, and AI-enhanced relevance using modern ML tooling.

About you:

• Experience building and owning backend infrastructure, ideally in Node.js, C#, or similar.
• Proven ability to take ambiguous problems from 0 → 1, including designing new systems and iterating without much prior art.
• Strong understanding of distributed systems (microservices, pipelines, indexing jobs, etc.).
• Experience with search engines such as Elasticsearch, OpenSearch, Lucene, Solr, Typesense, or other.
• Familiarity with search-specific tuning: analyzers, BM25, shard sizing, cluster health, and relevance optimization.
• Comfort managing infrastructure using tools like Kubernetes, Terraform, and Atmos.

Nice to have:

• Familiarity with semantic search, embeddings, and tools like Faiss, Weaviate, Cohere, or sentence-transformers.
• 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.
• 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.

About us:

Our mission is to make the life of blue-collar workers easier worldwide by creating software that meets their needs and realities. Our product is truly life-changing for that 80% of the workforce who doesn’t work behind a desk and needs enterprise-grade software at their fingertips.

MaintainX is committed to creating a diverse environment. All qualified applicants will receive consideration for employment without regard to race, color, religion, gender, gender identity or expression, sexual orientation, national origin, genetics, disability, age, or veteran status.
