Selr AI, AI Systems Developer
Location: Selr AI HQ, 2/40 Pacific Avenue, Miami QLD 4220 (Gold Coast)
Join Selr AI: build the systems businesses actually run on
Are you a sharp developer who would rather ship a working system than sit in another sprint ceremony?
Selr AI is an AI adoption partner. We help business owners adopt AI with confidence, from first step to business-wide transformation. We don't build AI businesses; we build AI-capable businesses.
That takes real engineering. We build the agents, skills and connectors that get installed across a client's entire team in a single day, and the client owns the code when we leave.
The Role
As an AI Systems Developer you build the infrastructure behind everything we deliver: the agent roster, the skill library, the connectors into client software, and the internal platform Selr AI runs on.
Every engagement is different. A gym franchise needs five systems wired up that have no public integration. A property group needs its reporting consolidated. You scope it, build it, test it, and hand it over.
What You'll Be Doing
- Building Claude Code skills, agents and MCP connectors against real client software, packaged so a non-technical team can actually run them.
- Writing production TypeScript/Node and Python: API integrations, custom MCP servers, data pipelines, internal tooling.
- Shipping and maintaining our own platform work on Next.js, Vercel, Supabase, and agents running on AWS.
- Automating internal operations in n8n and GoHighLevel where a workflow beats writing code.
- Pre-building a client's stack before an on-site install day, so the day itself is install and go rather than start from scratch.
- Working alongside Luke and Harvey on builds, and occasionally with clients over email during prep.
- Staying current. Tooling in this space changes monthly and we move with it.
Who We're Looking For
You're technically strong, quick to learn, and comfortable with a spec that starts as a conversation instead of a ticket.
- Fundamentals: solid JavaScript/TypeScript or Python. SQL is a bonus.
- Working knowledge of APIs, auth flows and webhooks. If you've built against a messy third-party API and survived, tell us about it.
- Problem-solver: creative and analytical, happy to be the first person to make something work.
- Learning agility: eager to go deep on Claude Code, the Anthropic SDK and MCP. Prior experience there is a bonus, not a requirement.
- Collaborative: high-performance team, low ego, quick to ask and quick to help.
- Culture fit: discipline, growth, "Think Different", "Never Stop Growing".
Why Join Selr AI?
- Real ownership: your builds go into client businesses and stay there. Nothing you write ends up as demo-ware.
- Frontier tooling as the day job, not a weekend side project.
- No corporate bureaucracy. Fast-moving team, no micromanagement, room to carve out your own lane.
- Variety: real estate, e-commerce, gyms and franchises, property, professional services. No two builds are the same.
- Exceptional culture: a supportive team focused on discipline, continuous learning, and celebrating wins. We prioritise people and a "Home First" mindset.
- Competitive compensation and progression: rapid progression and incentives for high performers. Additional hours are welcome if you're keen to work more.
- Trial period: all new team members begin with a paid 1-month crash course trial, followed by a 3-month paid probationary period.
- Modern workspace: brand new screens and your own desk provided. Bring your own laptop to plug into the setup.
