Senior Full-Stack Engineer (Ruby on Rails + React)

Remote | ⚙️ Full-Time (40+ hrs / week) | Fast-Growth Startup | Contract or Contract-to-Hire

We are a fast-growing, VC-backed retail audit & execution platform that helps brands diagnose planogram compliance and optimize merchandising and category management workflows. Our tools connect real-world retail execution with an intelligent analytics backend powered by data, video workflows, and CVAI.

We’re a small, highly collaborative, and fast-moving team. You’ll work directly with founders, technical leadership, and product teams — influencing architecture decisions, shaping internal tools, and contributing to high-impact product areas.

• Build and maintain data-driven dashboards using Ruby on Rails + React
• Develop backend logic, algorithms, and data pipelines in Rails
• Improve and expand internal Admin tooling for operations, analytics, and sales
• Work on backend components powering the mobile app used by field shoppers; ensure consistency between mobile data flows and dashboard experiences.

• Work closely with the CTO to ensure backend data is translated into clean, functional UX
• Communicate timelines, tradeoffs, and constraints to non-technical founders
• Provide thoughtful code reviews for junior developers
• Mentor junior developers on architecture and best practices (not people management)

• Build and integrate APIs between internal systems and external services
• Work with third-party tools (marketing automation, payments, workflow systems)
• Improve performance, maintainability, and reliability across the codebase
• Identify and fix bugs across frontend, backend, web, and mobile
• Write unit tests and elevate testing best practices over time
• Maintain clean, well-structured, well-documented code

• Must Have 5–8+ years of full-stack engineering experience
• Strong proficiency with Ruby on Rails (backend, APIs, logic, data flows)
• Strong proficiency with React (frontend features, UI state, components)
• Experience working across the stack: backend services, APIs, frontend, and internal tools
• Ability to work with both new systems and existing / legacy code
• Experience with data handling, scaling, and performance optimization

• Adaptable, fast, independent, detail-oriented
• Strong communication skills, especially with non-technical stakeholders
