CO-Ver | Fullstack & Senior Fullstack SWE | Remote US | $125k-$175k DOE + Equity | 1099 Contract-to-Hire | Self-funded

GCs routinely overbill 10-15% on change orders, and owners have no systematic way to catch it. CO-Ver is building software to help owners and developers review, validate, and challenge construction change orders before they pay them.

The product combines document ingestion, scope/cost comparison, estimate review workflows, and LLM-assisted analysis with human estimators in the loop. MVP is nearing completion. We're targeting production by mid-July, self-funded, intentionally small, and working directly with customers in a painful, expensive, and underserved market. You'll work with the founders and fractional CTO, have a real voice in product and architecture decisions, and receive early-stage equity.

Open roles: Fullstack SWE ($125k-$155k): 3+ years, strong TypeScript, React/Next.js, solid data modeling, interest in LLM-assisted workflows

Senior Fullstack SWE ($150k-$175k): 5+ years, deep TypeScript, production Next.js/multi-tenant SaaS/LLM features, comfortable owning architecture decisions

Nice to have: Convex, Clerk, Tailwind v4, PDF pipelines, construction domain knowledge

Stack: Next.js · React 19 · TypeScript · Convex · Clerk · Tailwind v4 · Anthropic API · Vercel · GitHub Actions

Full-Stack Engineer with 3+ years of experience building production-ready React/TypeScript systems for SaaS, fintech, AI workflow, and data-heavy products.

I’m strongest in frontend-focused full-stack work: polished React/Next.js product interfaces, dashboards, auth flows, protected routes, API integrations, database-backed features, Stripe billing, deployment, QA, and debugging the production issues behind the UI.

Recent projects include MindPad AI, Flowstate, AtlasBrief, GeoRisk, and EchoRoom. These are not basic portfolio clones — they include real auth, payments, persistence, AI-assisted workflows, dashboards, billing logic, team flows, and deployed production-style architecture.

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
