Full-Stack
AI Engineer
Build AI-native websites and open-source infrastructure for mid-market companies leaving legacy SaaS. AI tooling isn't a bonus skill here. It's the baseline.
About Lynton
Lynton has been building for the web since 1999. We spent 16 years as a HubSpot partner, 2,000+ custom projects across 50+ industries, then left to build what comes next: AI-native websites and open-source infrastructure for companies taking back ownership of their digital operations.
We're a small team. Our website, our tools, our AI delivery pipeline are all built on the same stack we deploy for clients. If we sell it, we run it.
The role
You build production websites and open-source infrastructure for mid-market companies leaving legacy SaaS platforms. Full builds, architecture through deployment, on a modern open-source stack with AI tooling as the default workflow.
This isn't just marketing sites. Full-stack products, interactive web experiences, and applications shipped as our clients' new brand identity. Deterministic and autonomous AI agents woven into client infrastructure. Composable marketing & tech stacks pulling from the best open-source projects available: analytics, email, automation, CRM, vertical solutions.
The sites push what a brand's digital presence can be. They project authority in search, AI discoverability, and brand awareness. You make design and UX decisions within established brand systems, not implement someone else's Figma files. Strong front-end instincts matter here.
This is a "Full-Stack AI Engineer" role on purpose. AI tooling (Cursor, Claude Code, Aider) is not a bonus skill. It's the baseline of how we build. If you don't already work this way every day, this isn't the role for you.
The founder builds daily with AI agents and sets the technical and creative direction. You own execution end-to-end and help shape how the company delivers as we grow.
What you'll do
- ▸Build client websites on Astro, Next.js, and React, architecture through deployment
- ▸Deploy open-source infrastructure for clients: CRM, analytics, email, automation, connected through a shared data layer
- ▸Make front-end design decisions within brand systems: typography, layout, responsive behavior, interaction patterns
- ▸Work with AI coding agents daily (Cursor, Claude Code, Aider). This is how we build, not something we're evaluating
- ▸Build and extend AI agent workflows for internal tooling and client delivery
- ▸Migrate legacy CMS clients to modern frameworks without losing data, SEO rankings, or operational continuity
- ▸Scope and estimate projects alongside the consulting team
Who you are
- ●2–4 years full-stack experience in TypeScript / JavaScript
- ●Comfortable with React, Next.js, Astro, or similar modern frameworks
- ●Experience with Node.js APIs, REST integrations, and at least one database (Postgres, MongoDB, or equivalent)
- ●You build with AI coding tools every day. Cursor, Claude Code, Aider, or similar. Pick your favorite, but you're already living in one of them.
- ●Strong eye for front-end craft: whitespace, type hierarchy, visual rhythm. It shows in your work
- ●You can own a project end-to-end without waiting for a spec
- ●You've deployed to Docker-based hosting or managed platforms
- ●Comfortable with ambiguity. We're writing the playbook, not handing you one

Why this role
- Your work ships to real clients immediately. No six-month onboarding. No approval chains. Small team, direct impact.
- AI tooling is the core workflow. Not a pilot program. You ship faster than you thought possible and learn faster than anywhere else.
- You shape how the company works. Processes don't exist yet. The engineer who joins now defines how Lynton delivers for the next five years.
- Real credibility behind this. 27 years in business. 2,000+ client engagements. A legacy revenue base. Not a pre-revenue startup. A company on its third act.
- Full-stack means full-stack. AI agents, open-source infra, and client-facing design. Breadth and ownership.
No cover letter.
Just signal.
Four short questions designed to surface what resumes can't. How you actually work, what you've actually shipped, what you actually decide.
Applications are screened by an AI calibrated to the role criteria, then reviewed by a human. Specific answers beat polished ones. Generic AI-generated responses won't make it through.
