Currently Opened Roles

Ads Auctions| Sr. Data Scientist I (L5)

The Ads Auctions team is responsible for innovating and enhancing auction mechanisms to create a competitive and transparent marketplace that benefits both advertisers and consumers. In this role, you’ll own analytical frameworks and simulations that shape the evolution of our CPC pricing, bid optimization, and auction selection processes—running rigorous experiments to evaluate mechanism changes such as bid shading and dynamic pricing. You’ll partner closely with Engineering, ML, and Product to translate business needs into well-specified model requirements, and apply expertise in auction theory, mechanism design, and econometrics to ensure our systems are fair, efficient, and aligned with marketplace goals.

AI for Analytics | Sr. Data Scientist II (L6)

Instacart is developing AI-powered systems to accelerate analytical work and enable self-serve analytics at scale, with a goal of 2x-ing the number of features launched by end of 2026. As a Senior Data Scientist II, you’ll own product strategy and AI expertise—identifying high-impact opportunity areas and deploying AI and ML systems in production settings. This is a senior cross-functional leadership role: you’ll shape the product roadmap, ruthlessly prioritize across competing stakeholders, and set the analytical direction for how Instacart’s data experts and AI systems work together.

Order Experiences (Search) | Sr. Data Scientist I (L5)

The Order Experiences (Search) team is focused on making it fast and effortless for customers to find the right items and complete their order with confidence. As a Senior Data Scientist, you’ll own the analytics and experimentation strategy that powers how we interpret customer intent and surface the most relevant results—driving search conversion, order rate, and GTV. You’ll partner closely with Product, Engineering, and ML to shape the roadmap for search relevance and ranking quality, running experiments across retrieval, ranking, and search UX while connecting offline model evaluation to real-world business outcomes.

Ecosystems | Sr. Data Scientist II (L6)

The Ecosystems team tackles some of Instacart’s most strategic macro-level analytical challenges, including quantifying the impact of economic trends, competitive dynamics, and seasonality on core business metrics. As a Senior Data Scientist II, you’ll own time-series forecasting for key business outcomes, develop measurement frameworks for evaluating competing growth initiatives, and build AI tooling to scale analytics workflows across the team. This role also carries a technical leadership dimension—you’ll set the methodological bar, mentor peers, and review analyses to drive rigor across the organization.

Delivery | Sr. Data Scientist II (L6)

The Delivery team is dedicated to ensuring customers receive their complete orders seamlessly, spanning the full flow from capturing customer information to coordinating the shopper experience. As a Senior Data Scientist II, you’ll identify strategic opportunities to enhance the delivery experience, design and execute rigorous experiments to evaluate new product features, and leverage geospatial data and advanced analytical techniques to optimize logistics. You’ll also proactively identify high-risk delivery scenarios and develop solutions to the underlying systemic issues that drive them.

Marketing | Sr. Data Scientist I (L5)

The Marketing Data Science team is responsible for measurement and optimization across Instacart’s paid digital channels, including search, shopping, display, social, and video. As a Senior Data Scientist, you’ll build and maintain sophisticated attribution models—including multi-touch and incrementality-based approaches—and develop scalable data pipelines to turn raw marketing data into clean, analysis-ready datasets. You’ll apply causal inference methods such as geo holdouts and difference-in-differences to evaluate campaign effectiveness, partnering closely with marketing, data engineering, and business teams to define measurement frameworks and drive data-informed decisions. You'll also model user lifetime value (LTV) across acquisition cohorts, quantifying how marketing spend and channel mix influence long-term retention and monetization to inform budget allocation and growth strategy
