VitaUp operates in one of the most competitive and sophisticated categories on Amazon: Health & Wellness. 

Our brands compete alongside industry leaders such as NOW, Pure Encapsulations, and Nature Made. We already have proven products, strong unit economics, and a solid operational foundation — and we're now looking for the right person to take our affiliate channel to the next level.

Who We're Looking For

We're hiring an Affiliate Manager to find, build, and grow partnerships that drive traffic to VitaUp on Amazon and on our own website, with the ultimate goal of increasing sales. This role also owns the analytics side of the channel — tracking performance, testing hypotheses, and identifying the most effective paths to growth. Building brand awareness along the way is a welcome bonus, not the primary mandate.

This is a role for someone who thrives on ownership. You'll be expected to identify opportunities independently, negotiate partnerships, and communicate professionally with affiliates — without needing constant direction.

What You'll Do

• Identify, approach, and onboard new affiliate partners with proven sales potential
• Manage and grow relationships with existing partners to maximize channel performance
• Drive traffic and sales growth across Amazon and our own website through the affiliate channel
• Build and maintain a reporting system to track performance, budgets, and key metrics
• Design and run hypothesis-driven tests to find the most effective growth levers
• Manage allocated budgets efficiently to maximize return on investment
• Contribute to brand visibility and awareness as a secondary outcome of channel growth

What Success Looks Like

• Significant growth in channel sales volume within the first 12 months
• An expanded partner network, built through new affiliates with demonstrated sales potential
• High resource utilization and target attainment, starting from month 3
• A functioning reporting and testing system in place from month 2 onward

What We're Looking For

• A strong bias toward efficiency — the ability to drive significant results with minimal wasted effort
• Decisive, organized, and self-directed working style
• A fast learner, comfortable operating with a high degree of autonomy
• Willingness to put in the work needed to hit ambitious targets
• Strong negotiation and communication skills — you can build trust with partners quickly and professionally
• Prior experience in affiliate marketing, e-commerce, or Amazon growth roles (Health & Wellness category experience is a strong plus)
• Familiarity with FTC/FDA advertising guidelines for supplements is a plus, given the regulatory sensitivity of health claims in this category

What We Offer

• Direct impact on company growth and operations
• Close collaboration with founders from day one
• High autonomy and real ownership
• Remote-first, with flexibility and trust
• Competitive USD-based compensation with bonuses
• Room to grow as the business grows

At Fozzy Group, we are developing a next-generation Decision Support System that connects operational, commercial, and investment data to optimize financial effectiveness and drive guest experience. As a Data Scientist you will own the measurement layer to derive Initiative & Investment Performance Insights. The role 

is organized around three streams: 

• Effect Measurement & Causal Inference: quantify the true incremental impact of initiatives using A/B testing and quasi-experimental methods. Measure uplift in purchase frequency, guest spend, average check, and retention against properly designed control groups, and form clear conclusions on whether an initiative works and is worth its cost. 

• Driver & Heterogeneity Analysis: identify the most significant factors of project performance using ML: guest profile structure and dynamics, technology presence, assortment, distance to competitors – so the business can assess project potential per store, forecast effects, and scale more effectively. 

• Self-Service Validation & Monitoring: build reusable, automated frameworks for effect validation and monitoring that let Finance and business owners get verified answers on demand, with full source transparency and reproducibility.
You will join a cross-functional team to design and implement data-driven decision module that directly influence financial outcomes. 

Job Responsibilities 

• Design and run experiments (A/B tests) and quasi-experiments (difference-in-differences, synthetic control, propensity score matching), and apply causal ML to estimate the incremental and heterogeneous effects of operational, commercial, and investment initiatives. 

• Build uplift / heterogeneous-treatment-effect models to learn which guests, segments, and stores respond most, and quantify effects on key metrics – purchase frequency, share-of-wallet / guest spend, average check, CLV, and retention (via survival models) – for pilot versus control groups. 

• Develop interpretable driver models (gradient boosting with SHAP, causal forests) that explain project performance, and rank the factors with the highest impact on results. 

• Build store-level potential-scoring and effect-forecasting models – probabilistic and hierarchical forecasting, transfer learning and store embeddings to borrow signal across the network – to guide and prioritize scaling decisions. 

• Design adaptive early-stop logic using Bayesian sequential testing, multi-armed bandits, and change point detection, to reallocate or halt rollouts as soon as the economic signal turns marginal. 

• Translate financial and commercial questions into statistically rigorous measurement designs, and connect statistical results to economic value (incrementality, ROI, payback). 

• Build SQL and Python pipelines, reusable feature sets / a feature store, and a self-service experimentation framework. 

• Productionize and monitor models (MLOps) – drift detection, automated validation, reproducibility, and source transparency. 

• Partner with Finance, Investment, Commercial, and Operations teams to deliver verified, decision ready insights. 
 

Requirements 

• Bachelor’s Degree in Mathematics / Quantitative Economics / Econometrics / Statistics / Computer Sciences / Finance; 

• At least 2 years working experience on Data Science; 

• Strong foundation in Statistics, Causal Inference, and Experimental Design – A/B testing, Hypothesis Testing, Power Analysis; 

• Proven experience with SQL (Window functions, CTEs, joins) and Python; 

• Expertise in Machine Learning, Time Series Analysis; 

• Ability to work independently and decompose complex problems. 
 

Preferred 

• Experience with Airflow, Docker, or Kubernetes for Data Orchestration;
