About Maincode

Maincode makes Matilda, an Australian-made AI stack we run end to end, from tin to token. We operate our own infrastructure here in Australia, train and maintain our own frontier models, and run multiple surfaces on top of them, including chat, coding, and APIs. Everything we ship is built on capability we control ourselves. We are hiring a true believer and a relentless operator to tell Matilda's story. We need a compelling storyteller with a fierce, authentic commitment to seeing Australian-made AI take on the world. You must be a creative pragmatist, someone who crafts highly resonant narratives but executes with the technical precision, speed, and discipline of an engineer.

The Role

We value high agency, bold execution, and building from the ground up. We do not farm our voice out to agencies; true conviction requires being inside the firewall, working directly alongside the team that builds the product. To succeed here, you need to dive deeply into our technical footprint, review what we have built, and figure out how to scale our narrative globally. Everything you need to win is built in-house, and we expect you to leverage every channel and tool at your disposal to drive outcomes. Focus Areas & Capabilities

Technical Execution: You understand the technology deeply and operate as a self-sufficient builder. You use every available platform to ship fast and drive measurable results without relying on outside help.
Authentic Storytelling: Throw out the standard B2B rulebook. Translate complex technical milestones into clear, high-impact narratives that command attention.
In-House Evangelism: Take complete ownership of the brand. Champion the mission with the grassroots authenticity and conviction that only comes from being deeply embedded in the core team.

Details

Location: Melbourne, VIC
Type: Full-time, permanent
Remuneration: Competitive salary (commensurate with experience) + super + equity

Why work at Maincode

Culture: “Small team doing hard things.” High ownership, move fast, ship without permission. Values: ownership, gradient (fast learning), range, speed, taste, humility. No ego, mission‑first.
Work environment: On‑site in Melbourne, Australia (some hybrid/remote possible with visits). Emphasis on craft and shipping.
Research perks: For researchers – paid residency, ability to publish at top venues (NeurIPS, etc.), access to dedicated GPU cluster, direct line to production.
Engineering focus: Modern tech stack (Python, PyTorch, CUDA, Kubernetes, Terraform, GCP); engineers work on inference infrastructure, model training, safety evals, and product features.
Growth opportunity: From 17 people to planned expansion; early employees can shape the direction of the product and research agenda.

About Maincode

Company Overview

One-liner: Maincode is an Australian AI research and product company building Matilda, an intelligent assistant that understands context, learns your workflow, and helps you move faster and more safely.
Entity Type: Private (Bootstrapped – no external funding rounds disclosed)
Headquarters: Melbourne, Australia
Founded: Not publicly disclosed (recent high-growth signals suggest founding around 2024–2025)
Founders: Not publicly disclosed (Dave L. is listed as Chief Coder; founder status unclear)

Core Business

Primary industries: AI research, applied intelligence, product development for enterprise and knowledge workers.
Target customers: B2B (teams and individuals needing a nuanced, safe AI assistant), researchers, and developers.
Mission: “AI that earns trust in the real world, to move humans forward.” Focus on safe, transparent, and helpful AI systems.

Products & Services

Matilda (flagship product, private beta 2026): AI assistant with deep contextual understanding across long conversations, multi-step reasoning (inspectable steps), proactive but permission-asking behavior, learning of user workflows over time. Built and hosted in Australia, aligned with Australian privacy standards.
Maincoder (open-source 1B parameter model, released Dec 2025): Code generation and transformation model optimized for low latency and cost.
AI Research Residency (3–6 month paid program): For late-stage PhD students and early-career researchers. Provides access to Maincode’s GPU cluster, infrastructure, and direct collaboration with the core team; aims to publish at top-tier venues.
Inference infrastructure (MC-2 cluster): High‑availability, sub-200ms global latency inference using custom batching, model sharding, dynamic routing (CUDA, Kubernetes, Terraform, GCP, vLLM, AMD Instinct GPUs).
Context Engine & Action Layer: Proprietary frameworks for long-context reasoning and agentic tool-use/sandboxed execution (turning Matilda from chatbot to agent).
Eval Suite: Internal evaluation framework for model capability, safety alignment, task completion (10K+ scenarios, automated regression).

Market Standing

Valuation / Market Cap: Not disclosed.
Key Metric: Total funding not disclosed (appears bootstrapped). Headcount: 17 employees (+360% YoY). Monthly website visits: ~14,071 (+116.3% monthly, +56,184% yearly).
Notable Investors/Partners:
- Demonstrating first agentic payment transaction in Australia with Mastercard at the Australian Open 2026.
- Benchmarking study with Heidi Health (cloud vs on‑premise inference).
Growth Signals:
- 10 active job postings (quarterly increase +42.9%, yearly +150%).
- LinkedIn followers: 4,468 (+315.6% yearly).
- Traffic growth (56,184% yearly) and strong inbound interest from US (72%) and Australia (28%).
- Partnership with Mastercard for a live agentic payment demo signals enterprise traction.

Competitive Advantages

Australian privacy by design: Infrastructure and model behaviour aligned with Australian standards; transparency and user control emphasized.
Research‑to‑production pipeline: Tight integration between frontier research and a shipped product (Matilda). The research residency directly feeds into product improvements.
Agentic safety: Multi-step reasoning with visible steps, permission‑asking before action, and sandboxed execution – differentiating from black‑box chatbots.
Own GPU hardware: MC-2 cluster (AMD Instinct) allows full control over inference latency and cost.
Talent magnet: Small, high‑agency team attracts PhD‑level researchers with promise of publications and access to SOTA compute.

Strategic Focus

Scale Matilda’s user base (currently private beta) and move toward general availability.
Deepen research in safety & alignment, long‑context reasoning, multimodal perception, agent orchestration, and model efficiency.
Expand enterprise partnerships (evidenced by Mastercard, Heidi Health).
Continue growing the team across engineering and research (10 open roles across infrastructure, product, and research).
