We are seeking a skilled Machine Learning Engineer with deep expertise in building and optimizing recommendation systems within the consumer marketing space. The ideal candidate will have hands-on experience designing, implementing, and scaling personalized recommendation and targeting models that drive customer engagement, conversion, and revenue growth. Experience translating consumer behavior and marketing data into actionable, personalized experiences is essential.
Key Responsibilities:
Design and develop machine learning models for recommendation and personalization systems (e.g., collaborative filtering, deep learning, hybrid approaches) tailored to consumer marketing use cases such as product recommendations, next-best-action, and audience targeting.
Optimize models for scalability, performance, and real-time predictions across large-scale consumer datasets.
Collaborate with business leaders, marketing partners, product and engineering teams to integrate models into production and campaign pipelines.
Analyze and improve recommendation quality using metrics like precision, recall, click-through rate, conversion, and customer lifetime value.
Leverage customer segmentation, behavioral, and first-party marketing data to enhance personalization and relevance.
Experiment with cutting-edge techniques (e.g., reinforcement learning, graph neural networks, contextual bandits) to enhance recommendations and marketing outcomes.
Requirements:
5 years of experience in machine learning, with a focus on recommendation systems, ideally within consumer marketing, retail, e-commerce, or a related consumer-facing domain.
Proven track record building personalization or recommendation models that measurably improved engagement or marketing performance.
Proficiency in Python, TensorFlow, PyTorch, or similar ML frameworks.
Strong understanding of algorithms like matrix factorization, neural networks, and ranking systems.
Strong understanding of LTMs and agentic AI frameworks that can be customized for recommender systems.
Experience working with consumer/marketing data, including behavioral, transactional, and campaign data (familiarity with CDPs, marketing analytics, or A/B testing is a plus).
Experience with Databricks and AWS.
Excellent problem-solving skills and a passion for delivering impactful, customer-centric solutions.

Which visas can work for this job
Occupation: Data Scientists (SOC 15-2051).
- Mentioned in the listing
H-1B
- H-1B cap-exempt employer
Regular cap-subject employer — a new H-1B needs to win the lottery in March (unless you already hold cap-counted H-1B status).
- TN (citizens of Canada and Mexico)
This kind of role may fit the USMCA profession “Mathematician / Statistician” — it depends on the actual duties. No lottery, no cap; you need the matching degree or license.
- E-3 (Australia) and H-1B1 (Chile, Singapore)
Same degree requirement as H-1B, but no lottery and a separate quota that is rarely filled.
- O-1 (extraordinary ability)
For candidates with awards, publications, press, a high salary or critical roles at distinguished organizations. No cap, no lottery; the employer files a petition.
- STEM OPT extension (F-1 students)
Requires an E-Verify employer. We didn't find this company in the E-Verify list — ask HR.
- Green card (EB-2 / EB-3 via PERM)
Filed 14 PERM labor certifications: they have a track record of sponsoring permanent residence.
Salary vs prevailing wage
Data Scientists · New York-Newark-Jersey City, NY-NJ. Annual prevailing wages set by the Department of Labor (OFLC).
| Level | Prevailing wage | H-1B lottery odds* |
|---|---|---|
| Level I | $87,256 | ~15% |
| Level II | $115,835 | ~31% |
| Level III | $144,414 | ~46% |
| Level IV | $172,994 | ~61% |
The listing has no salary, so we can't place it on a wage level. Ask the employer which wage level they'd file at: Level III–IV registrations get 3–4 entries in the H-1B lottery.
* Odds are DHS projections for the FY2027 wage-weighted lottery (actual results vary by year and employer). Since the FY2027 cap season the H-1B lottery is weighted by wage level: Level I = 1 entry, II = 2, III = 3, IV = 4. The level is set by the offered wage against the prevailing wage for the occupation and worksite. Separately, a $100,000 fee for new H-1B petitions for workers outside the US was announced in 2025; as of September 2026 a federal court ruling keeps it unenforceable while appeals continue — check the current status.
