We recently completed a $150 million Series D round, at a valuation of $2.5 billion. We’re hiring a Senior AI Platform Engineer (Knowledge & Data) to build and own the LLM knowledge and retrieval layer that powers AI features across MaintainX. You’ll build backend services and pipelines that transform raw documents, APIs, and semi‑structured data into production‑grade knowledge systems, with clear patterns for ingestion, retrieval, ranking, and caching. Your work enables product teams to ship AI features quickly without re‑solving knowledge preparation, retrieval quality, or reliability problems.

The focus is on LLM‑facing knowledge systems, retrieval quality, and platform services that power AI products. What you’ll do Build scalable backend services and internal APIs for the AI platform. Integrate LLMs and retrieval into reliable, production‑ready workflows. Build knowledge ingestion pipelines for LLMs (documents, APIs, semi‑structured data). Design chunking and embedding approaches together with vector DB data models and indexing strategies. Implement retrieval pipelines (semantic, keyword, hybrid) and caching. Contribute to shared infrastructure: CI/CD, observability, deployments. You’re a good fit if you have 5+ years of experience in Python backend engineering and systems design experience. Experience shipping AI‑powered or LLM‑integrated backend systems. Experience with vector DBs (Qdrant/Pinecone/Chroma/etc.). Understanding of embeddings, chunking, and retrieval strategies. Experience building search or retrieval systems over unstructured data. Comfort working across multiple layers (services, data, infra, AI tooling). What’s in it for you Competitive salary and meaningful equity opportunities. Healthcare, dental, and vision coverage.

Voluntary Self‑Identification of Disability Form CC-305 Page 1 of 1 OMB Control Number 1250-0005 Expires 04/30/2026 Why are you being asked to complete this form? We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years. How do you know if you have a disability? A disability is a condition that substantially limits one or more of your “major life activities.” If you have or have ever had such a condition, you are a person with a disability. Disabilities include, but are not limited to: Alcohol or other substance use disorder (not currently using drugs illegally) Autoimmune disorder, for example, lupus, fibromyalgia, rheumatoid arthritis, HIV/AIDS Blind or low vision Cancer (past or present) Cardiovascular or heart disease Celiac disease Cerebral palsy Deaf or serious difficulty hearing Diabetes Disfigurement, for example, disfigurement caused by burns, wounds, accidents, or congenital disorders Epilepsy or other seizure disorder Gastrointestinal disorders, for example, Crohn's Disease, irritable bowel syndrome Intellectual or developmental disability Mental health conditions, for example, depression, bipolar disorder, anxiety disorder, schizophrenia, PTSD Missing limbs or partially missing limbs Mobility impairment, benefiting from the use of a wheelchair, scooter, walker, leg brace(s) and/or other supports Nervous system condition, for example, migraine headaches, Parkinson’s disease, multiple sclerosis (MS) Neurodivergence, for example, attention-deficit/hyperactivity disorder (ADHD), autism spectrum disorder, dyslexia, dyspraxia, other learning disabilities Partial or complete paralysis (any cause) Pulmonary or respiratory conditions, for example, tuberculosis, asthma, emphysema Short stature (dwarfism) Traumatic brain injury PUBLIC BURDEN STATEMENT: According to the Paperwork Reduction Act of 1995 no persons are required to respond to a collection of information unless such collection displays a valid OMB control number. This survey should take about 5 minutes to complete. #J-18808-Ljbffr
