Job Description
Full-Stack Engineer
BOI
Role Description We're looking for a Full-Stack Engineer to design and build the products that put AI in front of real users. This is applied engineering work: building responsive front-ends, robust back-ends, and the data and integration layers that connect them to AI systems running in business-critical environments. You'll take products from idea to deployment, owning the full path including architecture, implementation, performance, and the operational concerns that determine whether a system survives contact with users. What You'll Do - Design, implement, and ship products that wrap AI capabilities into user-friendly applications. - Build responsive front-ends, scalable back-end services, and the database and pipeline plumbing in between. - Work closely with AI engineers to integrate models, agents, and retrieval systems into customer-facing applications. - Own product performance metrics, including testing, observability, and feedback loops for confident iteration. - Collaborate with engineers, designers, and strategists, participating in client conversations from early scoping through delivery. Qualifications - 3+ years of experience shipping production web applications. - Background in computer science, math, physics, engineering, or another technical or scientific field. - Strong across the stack: comfortable in Python on the back-end (FastAPI or similar). - Confident with React, TypeScript, and modern front-end tooling. - Familiar with relational databases and integration work connecting services. Requirements - Take engineering fundamentals seriously: CI/CD, testing, version control hygiene, and code quality matter. - Comfortable deploying on a major cloud provider (Azure preferred). - Understand how to balance performance, cost, and maintainability. - Experience debugging production systems. - Fluent in using AI-assisted coding tools like Claude Code, Codex, and MCP-based workflows. How You Work - Treat product engineering as a craft, caring about UX details, performance, and observability. - Comfortable in a consulting environment with varying domains and constraints. - Able to translate between business problems and technical solutions. - Enjoy a fast-paced field, actively pulling in useful new models, frameworks, and patterns. - Push back when something doesn't make sense and care about building sustainable products. Contract & Setup We are open to both permanent employment and long-term contractor arrangements. The final setup will depend on your location, work authorization status, and local compliance requirements. Interested? If this sounds like a fit, apply with your CV and a short note on a product you've built that you're proud of. Bonus points for something we can actually look at!

These include labor markets and in some instances may include education, work experience and certifications. In addition to your pay, Target cares about and invests in you as a team member, so that you can take care of yourself and your family. Target offers eligible team members and their dependents comprehensive health benefits and programs, which may include medical, vision, dental, life insurance and more, to help you and your family take care of your whole selves. Other benefits for eligible team members include 401(k), employee discount, short term disability, long term disability, paid sick leave, paid national holidays, and paid vacation. About us: Target Merchandising is evolving at an incredible pace. We are constantly reimagining how we get the right product to the right guest even better, faster and more cost effectively than before. We are becoming more intelligent, automated and algorithmic in our decision-making, so that no matter how guests shop—in stores or online—we deliver the convenience and immediate gratification they demand and deserve. We’re looking for exceptional people who are proactive, creative, independent, innovative, risk-savvy and comfortable working in varying degrees of ambiguity. Are you a critical thinker who seeks out root cause and can analyze both qualitatively and quantitatively? Are you a creative problem-solver who simplifies problems, quickly identifies solutions, commits to a plan and then positively influences others to execute it? If so, you will have success on one of our dynamic teams. A role in Planning and Inventory Management means applying your specialized and well-informed point of view to what we buy, from whom, how much and where it needs to go from there. You’ll use the right combination of data and expertise to achieve the best possible product availability through proper inventory positioning. You’ll also focus on the efficient transportation of product around the world, while ensuring compliance with U.S. Customs regulations and achieving the best possible product availability through proper inventory positioning. You’ll not only establish and develop great relationships with our vendors to encourage on-time shipment and delivery to stores and ultimately guests, but you’ll also analyze transportation supplier capabilities and contracts for maximum speed, reliability and cost effectiveness. As a Merchandise Planner in Apparel and Accessories, you’ll provide in-season decision support, collaborate on assortment planning, recommend localization and channel strategies including cluster types and profiles, and lead demand forecasting. You’ll support the divisional strategy through your category expertise and partnerships with cross-functional teams and vendors. You will head up the open-to-buy process and decide on category-level investment and the financial validity of assortments. You will conduct root cause analysis for variation between supply and demand forecasts to support “chase-cancel” decisions and communicate implications to vendors. You’ll conduct scenario planning, build unit plans, and lead initial set planning and operationalization to optimize assortments. A large part of your role will be to interpret forecast results and conduct “what if?” analysis to guide your go-forward recommendations. You will validate the unit promo planning forecast, drive maintenance, risk analysis and decision-making by the Pricing & Promotion Center of Excellence. And you’ll run event forecast creation and flow, analyzing item lifecycles and driving recommendations on end-of-season management. Core responsibilities are described within this job description. Job duties may change at any time due to business needs. About you: • Four-year degree or equivalent experience • 2-6 years of relevant experience • 1+ years of Merchandising experience • Strong strategic, financial, and analytical skills; can easily translate data from an array of sources into insights and recommendations • Strong collaboration skills to partner with cross-functional teams • Flexible, resilient, and comfortable working in “grey areas” that are constantly changing This position will operate as a Hybrid/Flex for Your Day work arrangement based on Target’s needs.
