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

We're looking for a senior software engineer who writes clean, well-tested TypeScript and is genuinely curious about functional programming. You'll 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 Apple's 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.

Description

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 - it's high impact work at the core of Apple's operations. You'll 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 you're not already writing Elixir, you'll grow into it - we'll 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 you'll regularly help translate complex operational workflows into clear, maintainable software rather than just executing specs.

Minimum Qualifications

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 API's 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 maintainability

Preferred Qualifications

Experience 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
