About the Opportunity We're seeking a
Staff Machine Learning Engineer
to lead the science and systems that power our paid search marketing. You’ll design the causal measurement stack, ship models that influence bidding and budgeting in real time, and partner with marketing, data, and platform teams to drive profitable, incremental growth.
Location: Hybrid (3 days in office/2 days remote) – New York, NY or Los Angeles, CA
What You’ll Do:
Own causal measurement for paid search : Stand up uplift and incrementality frameworks (e.g., doubly robust learners, causal forests, DML, IVs, synthetic control, DiD, BSTS) to quantify lift beyond correlation.
Ship production models : Build and serve models that inform bids, budgets, and query-level targeting using signals like incremental CPA, tROAS, LTV, and heterogeneous treatment effects.
Design experiments & guardrails : Architect geo/cell tests and online experiments; handle power analysis, pre-trend checks, SUTVA threats, SRM detection, and sequential monitoring.
Integrate with ad platforms : Translate science into APIs/feeds for Google Ads, Microsoft Advertising, and SA360; validate against auction dynamics and Quality Score mechanics.
Data & MLOps leadership : Partner with platform teams to instrument events, build reliable feature stores and ETL (batch/stream), and establish monitoring for drift, bias, leakage, and attribution sanity.
Mentor & influence : Provide technical leadership across science, engineering, and marketing; set standards for methodology, code quality, documentation, and reproducibility.
Tell the story : Communicate trade-offs and impact to executives and non-technical partners; make the complex understandable and actionable.
What You’ve Done:
8+ years in applied ML/causal inference (or equivalent) with direct paid search/auction experience.
Expert in causal methods (uplift modeling, DML, IV, DiD/synth control, BSTS/Bayesian time series) and experimental design.
Strong software engineering: Python (pandas, numpy, scikit-learn, LightGBM/XGBoost), SQL; experience with Spark and one of AWS/GCP/Azure.
Hands‑on with A/B frameworks, power analysis, and measurement diagnostics (SRM, balance, interference).
Proven track record integrating with Google Ads/Microsoft Ads/SA360 and moving the needle on tROAS, CPA, LTV.
Clear communicator who can mentor senior ICs and partner with product/marketing.
Nice to Have:
Recsys, bandits/RL for bidding/budget pacing, MMM and privacy‑aware attribution.
Scala/Java or microservices experience; Airflow/DBT; Kafka/PubSub; Feast or similar feature stores.
Domain knowledge of auction theory, query taxonomy, brand vs. non‑brand dynamics, and budget rebalancing.
Staff‑Level Capabilities
Technical leadership through influence
rather than formal management authority.
Strategic thinking
with the ability to balance long‑term technical vision with immediate organizational needs.
Cross‑functional collaboration
skills to work effectively with Data Science, Product, and Engineering teams.
Communication skills
to inject technical context into high‑level organizational discussions.
Problem‑solving approach
for ambiguous, high‑impact technical challenges.
Mentorship and sponsorship
experience growing junior and mid‑level engineers.
What We Offer:
Accelerated Growth Environment : Immerse yourself in an environment designed for swift skill and knowledge enhancement, where you have the autonomy to lead experiments and tests on a massive scale.
Top Tier Compensation Package : Enjoy a rewarding compensation package that includes enticing stock incentives, aligning with our commitment to recognizing and valuing your contributions.
Flexible Time Off : Embrace a healthy work‑life balance with unlimited Flex Time Off, providing you the flexibility to manage your schedule and recharge as needed.
Comprehensive Benefits Package : Prioritize your well‑being with 401k, and premium Health, Vision, and Dental Insurance options.
Salary Range: $300,000—$350,000 USD
We are an equal opportunity employer and value diversity on our team. We do not discriminate on the basis of race, color, religion, sex, gender identity, sexual orientation, national origin, age, veteran status, disability, or any other legally protected status.
