Summer Software Engineering Intern

AES (associatedenvironmentalsystems.com) | Summer Software Engineering Intern | REMOTE (US, with occasional Boston-area days) | $30-40/hr | Full or part-time | June 15 – Aug 22, 2026
"The senior lead doesn't write code from scratch. Neither will you."
We're a tiny team building a field-service-management platform for AES, an environmental-test-chamber manufacturer. One senior lead, one part-time backend specialist, and we're hiring a summer intern. The product is pre-production with active user feedback driving the build — you'll ship features that real service coordinators and field technicians will use day-to-day.
The bar is NOT raw coding ability. We use Claude Code for all code generation. The bar is the ability to direct an AI at production engineering and catch it when it's wrong: schema literacy, diff-reading, end-to-end ownership.

Stack: Next.js 14 (App Router, RSC, Server Actions), TypeScript strict, Prisma + Postgres, Tailwind + shadcn/ui, NextAuth, Twilio, Anthropic SDK, Playwright. ~100K lines of TS with `any` banned by lint.
Must-haves: a track record building with AI tools (link your best AI-built work — a PR, a deployed project, or a repo, ideally with a CLAUDE.md), at least one shipped end-to-end project that runs somewhere a stranger can use, schema/data-flow literacy, clear written communication, strong academic record. TypeScript fluency NOT required from scratch.
Eligibility: US person, able to pass standard background check. We can't sponsor visas or hire F-1/OPT for this role.
Logistics: 20–40 hrs/wk flex, Mon–Fri, remote with occasional in-person days at AES Chelmsford MA or our coworking space in Waltham MA. W-2, paid hourly. Apps close June 8.
No leetcode. No whiteboard. Show us your best AI-built work — a PR, a deployed app, or a repo. Apply: https://tally.so/r/44pNxX
