ML Search Engineer
Search Engineer (Software Engineer III)
You must be eligible to work in the US without Visa Sponsorship.
ABOUT THE ROLE
We're building intelligent product search that understands intent, learns from behavior, and gets smarter over time. As a SeniorFull StackEngineer on the ML/AI Search team, you'll design and buildboththefrontend and backendsystems that power product discovery for millions of industrial buyers-from scalable retrieval pipelines,APIs, and Frontendinterfaces that make AI accessible.
This isn't a research role. You'll own the full lifecycle: prototyping ideas, shipping production-grade services on GCP, and iterating based on real user data. Strong Pythonand Reactengineeringisthe foundation-if you also bring experience in search systems, vector databases, or Elasticsearch, you'll hit the ground running from day one.
WHAT YOU'LL DO
Build & Ship Search and AI-Powered Systems
Design, develop, and deploy production Python services end-to-end-from retrieval and ranking pipelines through client-facing APIs.
Build and integrate ML inference pipelines: embedding models, transformer-based classifiers, LLM-powered query understanding, and reranking services.
Develop event-driven, real-time architectures using GCP services-Cloud Run, Pub/Sub, GKE, Cloud Functions.
Write clean, well-tested, observable Python backends; own your services through deployment, monitoring, andon-call
Drive frontend architecture decisions, establishing development standards, and creating reusable component libraries.
Contribute to Search Infrastructure
Work alongside the Search Architect and ML Architect to implement hybrid retrieval systems combining keyword search, dense vector similarity, and reranking.
Build and maintain Elasticsearch indexing pipelines, query services, and relevance tuning tooling.
Integrate vector databases (Pinecone,Weaviate, FAISS or similar) into retrieval workflows-even if this is new territory, you'll learn fast.
Instrument search pipelines with meaningful metrics: CTR, zero-result rate, latency-feeding the team's A/B experimentation loop.
Build clean, responsive, and production-ready interfaces from wireframes or Figma designs.
Own the Engineering Bar
Champion CI/CD, observability, testing, and infrastructure-as-code as non-negotiables, not afterthoughts.
Lead design sessions with Engineers and Architects; translate product requirements into clean, maintainable technical solutions.
Participate in code reviews and knowledge-sharing-actively raising the team's collective skill level.
WHAT YOU BRING
Must-Haves
Strong Pythonand Reactfoundation: 6+ years of professional backend or full-stack engineering experience with a deep Python/React (e.g.,Next.js, Vite.js, Remix.js, Gatsby.js)focus-async patterns, type annotations, testing, and production-grade service/componentdesign.
Cloud-native experience: Proven experience designing and deploying cloud-native applications (
GCP strongly preferred; AWS or Azure considered).
Hands-on experience building resilienthigh throughputmicroservices and RESTful/gRPCAPIs.
Solid understanding of containerization (Docker), orchestration (Kubernetes), and serverless paradigms.
Strong grounding in SOLID design principles and software craftsmanship.
Good communicator who thrives in cross-functional, agile teams alongside ML engineers, architects, and product owners.
Comfort using AI tools to accelerate development throughput.
Strong experience of using and managingMonorepos
Strong understanding of relational (e.g.,PostgreSQL, MySQL, Oracle) and non-relational databases (e.g., MongoDB, DynamoDB).
Mentorship: Provide guidance and technical knowledge sharing to mid-level and junior developers.
Strongly Preferred - Search & ML
You don't need all of these on day one-but the more you bring, the faster you'll contribute:
Search systems: Experience with search platforms:
Elasticsearch, OpenSearch,Solr, orAlgolia-index management, query DSL, relevance tuning.
Vector search: Familiarity with vector search concepts and tooling:
embeddings, approximate nearest neighbor (ANN), FAISS, Pinecone,Weaviate, or similar.
Exposure to ML/AI patterns: RAG pipelines, LLM integration, prompt engineering, or fine-tuning workflows.
Experience with AI orchestration frameworks such asLangChain,LangGraph, or Google ADK.
Infrastructure-as-code experience (Terraform,Pulumi,OpenTofu) and mature CI/CD pipeline ownership.
WHO YOU ARE
Fearless Builder
A working proof-of-concept beats a thousand slide decks. Speed and quality are both non-negotiable.
Relentless Learner
You pick up new technologies fast and have a genuine eagerness to master whatever comes next.
Architecture-Minded
You design scalable, fault-tolerant services as second nature and aren't afraid to challenge the status quo.
Ownership-Driven
Code isn't done until it's tested, documented, and monitored. Your name on a release means something.
Search-Curious
You may not have built a search system yet-but you're excited by the challenge and ready to go deep.
Team Multiplier
You give and welcome candid feedback and actively make the people around you better.
