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.
Applications go through our short form, not a CV drop: careers
The 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.
What we're building
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 ****: 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 actually work now.
Transactional sending, campaigns, automation flows, contacts, segmentation and deliverability, all of it drivable by prompt.
The dashboard is there when you want it, not because we force you through it.
Where we're up to
We came out of beta in June and we've been shipping hard since.
We won Vercel Day on Product Hunt this week, top prize for Agent Inboxes.
We're an official app in the ChatGPT App Store, and live in Claude, Codex, Cursor, Gemini, Windsurf, VS Code and Zed through MCP.
Backed by Eastend Ventures and Archangel Ventures, plus a group of Australian angels.
Who we are
George (CEO) and Ed (COO) 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 ****.




George and Ed also co-founded Bluethumb, Australia's largest online art marketplace, and ran Sendicate before that.
Our third rodeo.
What you'd do
Make the send path bulletproof.
When someone sends an email it either lands or it tells them exactly why not.
Build what customers ask for on calls, often the same week they ask for it.
Work on campaign building, contact imports, automation flows and deliverability tooling.
Build with AI in a way that scales as the team and users scale.
The stack
Rails 8.1, PostgreSQL, Redis, GoodJob, and 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.
Deployed with Kamal onto ARM instances on AWS, Vercel for the front ends.
Mailgun and SES for sending, Twilio for SMS, Stripe for billing.
Who we're looking for
One to three years with Ruby on Rails.
If you're a recent grad with good product instincts, apply anyway.
Product sense counts as much as the code.
Opinions about valuable software and good UX, and reasons behind them.
AI-native, you build with agents every day.
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.
Requirements
You must be based in Melbourne or Byron Bay.
That one is not negotiable.
Full time.
The rest of the team is spread across Australia and we get together regularly.
