Junior Ruby on Rails Developer.

Ship things immediately in a fast growing VC-backed AI start-up. Full time, hybrid in Melbourne or Byron Bay, working directly with our CTO.

Apply for this role

We're hiring our first junior developer. You'd work directly with Kam Low, our CTO, and everyone here has done this at least once already. You'd be the first person we bring in to learn it from the inside, on a fast-scaling, venture-backed team.

You can build an entire product by prompting Claude or Codex now. Then you get to email, and you're straight back into a dashboard from 2014: copying DNS records across by hand, dragging blocks around a template builder, clicking through six screens to schedule one send.

Nitrosend is email rebuilt for the way people work now. Transactional sending, campaigns, automation flows, contacts, segmentation and deliverability, all of it drivable by prompt. A customer connects Nitrosend to Claude, says "set up my sending domain, write a five email welcome series in our brand voice and send the first one to my list", and it happens in minutes.

We came out of beta in June. This week we won Vercel Day on Product Hunt for Agent Inboxes. We're an official app in the ChatGPT App Store, live in Claude, Codex, Cursor, Gemini, Windsurf, VS Code and Zed through MCP, and backed by Eastend Ventures and Archangel Ventures.

George and Ed co-founded SmartrMail, Kam joined as CTO, and together they grew it to 12,000 customers and 6 billion emails sent before selling it in 2022. George and Ed also co-founded Bluethumb, Australia's largest online art marketplace, and ran Sendicate before that. Our third rodeo. We move fast because we already know which parts of this are hard.

What you'd do

  • Make the send path bulletproof. An email either lands or it tells you exactly why not. That's the product, and it's the most valuable work here.
  • Build what customers ask for on calls, often the same week they ask.
  • Work on the parts people touch every day: campaign building, contact imports, automation flows, deliverability tooling.
  • Build with AI in a way that scales as the team and the user base scale. Everyone here uses Claude Code and Codex daily.

The stack

Rails 8.1, PostgreSQL, Redis and GoodJob, behind a REST API that everything else is built on. Vue 3 with Vite, Pinia and Tailwind on the front end. TypeScript packages for our MCP server, CLI and AI SDK. We deploy with Kamal onto ARM instances on AWS, with Vercel for the front ends. Sending runs through Mailgun and SES, SMS through Twilio, billing on Stripe.

You'd be hired to write Ruby. The rest is open if you want it.

Who we're looking for

  • One to three years with Rails. Recent grads with strong product instincts should apply too.
  • Product sense. You use the app, spot what's annoying, and fix it without being asked twice.
  • Opinions about good software and good UX, and reasons behind them.
  • You build with agents every day and you're getting better at it.
  • Video editing, design and content creation skills are a big bonus. We move quickly and regularly need to explain, demonstrate and launch what we're building.
  • You must be based in Melbourne or Byron Bay. That one is not negotiable. The rest of the team is spread across Australia and we get together regularly.

Nitrosend is the fastest email platform that works where you work. Prompt it from Claude. Trigger it from your code. Let it automate email marketing across the brands, products, and clients you manage in Codex.

It's full stack email automation inside your AI agent, not an email marketing tool with AI added.

We're obsessed with speed. Not because speed is trendy, but because speed is the thing that separates the people who ship things that change lives from the people who plan to ship. Every minute you spend configuring email automations is a minute you're not talking to customers, writing code, or selling.

We believe the best tools disappear into your workflow. You shouldn't have to learn our interface.

We're George, Ed and Kam, and we're building Nitrosend because the world has shifted and email hasn't caught up. Until now - welcome to faster email.
