Job Description :

We are looking for a Lead ML Engineer to take full ownership of the customer
next-generation search platform. You will bridge advanced information retrieval
(IR) modeling with high-throughput production systems — building, tuning, and
scaling hybrid search pipelines while owning the evaluation harness, performance
benchmarks, and master data integrations that guarantee extreme precision and
sub-second latency at scale.

This is a high-impact, end-to-end engineering role. You will shape the
architecture of a system that directly affects the experience of millions of
customers, while mentoring talented engineers and partnering closely with
product and data stakeholders.

WHAT YOU'LL DO

Search Core & Information Retrieval

* Design, build, and tune a hybrid search engine combining Vector Search
(semantic) and Lexical Search (BM25/keyword) to deliver best-in-class
relevance.

* Implement advanced ranking and blending strategies including BGE rerankers
and Reciprocal Rank Fusion (RRF).

* Own end-to-end search accuracy and relevance metrics (NDCG, MRR,



Recall) and
drive measurable, data-backed improvements over time.

Evaluation & Quality Assurance

* Build and maintain an automated accuracy evaluation harness for continuous,
regression-proof pipeline testing.

* Establish quality benchmarks and champion a metrics-first engineering culture
across the team.

Performance, Scalability & Infrastructure

* Conduct systematic load testing (Locust, k6) and stress-test retrieval
pipelines to surface and eliminate bottlenecks.

* Architect and optimize systems to guarantee a strict SLA of P95 latency <
500ms under peak production load.

* Partner with DevOps/MLOps to design scalable, resilient deployment patterns
for search and ranking models.

Data Engineering & Governance

* Manage ingestion pipelines for Master Data Management (MDM) feed integration,
ensuring clean and timely data synchronisation.

* Govern schema and operational configurations within t
