Senior Applied Scientist

Role Description

The Afresh Intelligence team is responsible for the development and performance of AI/ML models that power our core replenishment technology. Our models are directly responsible for ordering millions of dollars of fresh inventory across the world every day. Fresh food ordering is an extremely complex high-dimensional decision-making problem, and we face the complex challenges presented by:

• Decaying product
• Uncertain shelf lives
• Varying consumer demand
• Stochastic arrival times
• Extreme weather events
• Tight performance constraints

We tackle these problems with a mix of machine learning, large-scale simulation, and optimization technologies.

We are looking for a Senior Applied Scientist to drive R&D work at Afresh. You will take your existing knowledge of machine learning, forecasting, operations research, and stochastic optimization and apply it to the challenging and important problem of perishable inventory control. You will research, implement, and rigorously validate improvements to our core replenishment system. This will include modeling consumer demand, item-level perishability, and complex multi-echelon supply chains. Your work will be visible from day one, will make a substantial impact on decreasing food waste, and will lead to fresher, healthier produce for millions of people across the world.

Qualifications

• MS or PhD in Operations Research, Industrial Engineering, Computer Science, Electrical Engineering, or another quantitative field, or equivalent practical experience.
• For candidates with an MS, 4+ years of industry experience; for candidates with a PhD, some industry experience preferred.
• Experience researching and building systems that support large-scale decision making under uncertainty.
• Prior experience or academic knowledge in areas such as inventory optimization, supply chain management, network optimization, forecasting, game theory, decision analysis, stochastic optimization, approximate dynamic programming, or related fields is a plus.
• Excellent communication and presentation skills.
• Ability to independently deliver high quality software implementations of your solutions in the Python data stack (numpy/torch/pandas/etc).
• Nice to Have skills: understanding of ML Platform and a passion for mentorship.

Requirements

• Model complex problems such as inventory decay, promotions, price elasticity, and inventory uncertainty, and implement solutions to multi-stage and multi-echelon inventory optimization problems.
• Drive fundamental changes to our core system from research through production, writing rigorously tested and scalable code.
• Advance research and development for new product and business challenges.
• Raise the technical bar across the Intelligence team: mentor scientists and engineers, set standards for experimental rigor, and review designs and results.
• Push the boundaries of AI capabilities in both products and scientist workflows.

Benefits

• Comprehensive medical, dental, and vision coverage for you and your family, with the majority of premiums covered by Afresh.
• Dedicated mental health support and counseling services.
• Competitive base salary, meaningful equity (U.S. employees), and a 401(k) program with a generous company match.
• Home office stipend and "Coworking Wallets" for flexible workspace access.
• Annual professional development budget to master new skills and grow your career at Afresh.
• Monthly stipends for "Betterment" (wellness/lifestyle) and telecommunications.
• Flexible paid time off to recharge.
