Senior Software Engineer - Full Stack (Node.js/TypeScript/functional)

Were looking for a senior software engineer who writes clean, well-tested TypeScript and is genuinely curious about functional programming. Youll work across two production applications, one in Node.js and one in Elixir, building features used daily by the engineers and operations teams who design and manufacture Apples products.

You should be someone who gets energized by learning new paradigms. We work in a small, high-trust team where good judgment matters as much as technical depth, and where AI-assisted development is part of how we work. This position sits within the Manufacturing Design and Environmental Systems teams.

Our team builds the applications that enable Apple to manufacture every product we ship - its high impact work at the core of Apples operations. Youll be someone who anticipates problems without over-architecting solutions, and who can distill complex challenges into clear, simple outcomes. We care about code that works correctly, performs well, and is easy for the next person to understand. That means writing tests, giving substantive feedback in code review, and debugging production issues when they arise using monitoring and logging tools. If youre not already writing Elixir, youll grow into it - well support that learning, but genuine curiosity about functional programming is a prerequisite for enjoying the work here.

You'll be building and maintaining features in close collaboration with product designers, domain experts, and other engineers. We involve engineers early in the design process, so youll regularly help translate complex operational workflows into clear, maintainable software rather than just executing specs.6+ years in a senior software role working across the entire web stack with a skilled team. 5+ years writing production JavaScript or TypeScript single page apps using React or similar framework with comfort working across the stack: you can pick up a SQL query, an API endpoint, and a UI component in the same day. 4+ years building and maintaining robust HTTP APIs and backend services. 4+ years developing complex applications with SQL based database solutions (PostgreSQL, MySQL etc.) at medium scale Familiarity with functional programming concepts - whether through Elixir, Haskell, Clojure, Scala, or just a strong interest in learning them Discipline in writing tests and a genuine interest in code quality and maintainabilityExperience in manufacturing or environmental systems Experience in Elixir, Erlang/OTP or other functional programming languages Experience building or overseeing AI agent development Experience with observability tooling: Prometheus, Grafana, Sentry, or similar Experience with Docker and deploying to production environments Experience working with international teams or counterparts Manufacturing or supply chain domain exposure 10+ years of professional experience in technical environments
