Jobs at NewsBreak

Build and maintain backend and data pipelines powering ads, personalization, and retention systems. Contribute to recommendation algorithms, feature pipelines, experimentation infrastructure, revenue operations tooling (commission/quota), and observability for large-scale user and engagement data. Collaborate with product, sales, and finance to ship reliable, low-latency production systems and monitoring.

Lead post-training for LLMs (CPT, SFT, RL) focusing on RL methods; design and curate training and reward data; run and debug distributed training on mid-to-large GPU clusters; build evaluation and verifier pipelines; partner with product and business teams to deliver targeted model improvements quickly.

Design and develop machine learning infrastructure, enhancing core components for model training, monitoring, and serving. Collaborate with ML engineers on robust pipelines.

Build and own an agentic creative pipeline that generates, vets, and optimizes thousands of image and video ad variants daily: extend LLM critic feedback to multimodal assets, build fast cost-efficient video pipelines, route generative models by cost/quality, train and deploy brand-style checkpoints, implement policy pre-flight checks, and ship event-triggered ad pipelines with A/B validation in production.

Own and scale streaming Kafka pipelines and large-scale Spark batch jobs processing billions of rows. Drive pipeline reliability, observability, data modeling, and cost/latency optimizations. Partner with data scientists and platform engineers, define SLOs, improve efficiency, contribute to shared infrastructure (Airflow, libraries, data catalog), and mentor junior engineers.

As a Growth Intelligence Engineer, you will develop data pipelines, recommendation algorithms, oversee revenue operations, and utilize data analysis to enhance user engagement and retention.

Design and build search-ranking, two-sided marketplace matching, retrieval/recall, and dispatch models. Own end-to-end learning-to-rank pipelines, run causal experiments (A/B, switchback), apply modern ML/LLM methods, and optimize relevance to improve marketplace conversion at production scale.

Build and scale NewsBreak's local knowledge graph: POI/places schema and ontology, entity resolution/linking, multi-source POI fusion, and data-quality systems. Ensure graph accuracy over time and partner with intent and matching teams to power search, discovery, and matching.

Own a local commerce/local services vertical end-to-end: define strategy, roadmap, launch, and growth with P&L ownership. Lead 0→1 category validation, MVP, and go-to-market (supply acquisition, demand, pricing, liquidity). Partner with engineering and data science to embed AI/LLM features and use marketplace metrics to prioritize and measure impact.

Design and build end-to-end signal-to-model pipelines: large-scale feature engineering, identity prediction and embeddings, integrate outputs into ads targeting/bidding, own model lifecycle, ensure low-latency online serving, improve signal quality, run A/B tests, and provide technical leadership across Ads, Data, and Infra teams.
