Senior Backend Engineer

About the Role Join a small, fast-moving engineering team building the backbone of an AI-powered supply chain platform for Consumer Packaged Goods companies. As a Senior Backend Engineer, you'll own backend systems end-to-end — turning messy, real-world logistics data into programmable, reliable infrastructure that scales globally. What You'll Do Design and implement backend systems that power AI-driven supply chain planning and execution decisions. Architect data models and pipelines to ingest and organise complex, real-world supply chain data. Ensure user requests and supply plans are processed in real time with high reliability. Build scalable, high-performance SQL queries and data access patterns over large datasets. Ship production-grade services using modern backend frameworks and rigorous testing practices. Collaborate closely with product and engineering to translate logistics workflows into software. Operate and improve deployment and runbook processes to maintain 24/7 system availability. What We're Looking For 5+ years of hands-on backend engineering experience with a track record of shipping real products. Strong Python expertise and experience with modern backend frameworks such as FastAPI and testing tools like pytest. Proficiency with AI-assisted code generation and management tools (e.g., Claude Code, Codex), including experience parallelising instances for continuous operation. Proven ability to design scalable data architectures and own backend systems end-to-end, including real-time request processing. Strong SQL skills and experience writing high-performance queries across millions of records. Experience ingesting and organising unstructured, messy real-world data. Familiarity with DevOps practices and cloud infrastructure (AWS preferred). Bonus: experience with frontend frameworks and their testing. Comfortable working with minimal supervision in a small, fast-paced startup environment. Compensation & Benefits Salary range: $110,000 – $200,000 USD annually . Visa sponsorship is available.
