About MotorPlatform

MotorPlatform is Australia’s fastest-growing B2B automotive marketplace and SaaS platform.

The core platform is built. The next phase is the hard, high-leverage work: scaling product, scaling engineering, and scaling operational excellence, while we shift to being AI-first in how we build and how the platform creates value.

The role

We’re hiring a Senior Full-Stack Engineer to act as Deputy Lead / 2IC in engineering. You’ll be a hands-on builder who can take ownership of major initiatives, lead projects end-to-end, and keep delivery moving with clarity and discipline.

Onsite in Sydney. We want fast feedback loops, high collaboration, and strong product-engineering alignment.

What you’ll be doing (this is a scale role, not a “greenfield” role)

You’ll work on the problems that show up when something is already working and growing fast:

• Scale system performance, reliability, and developer velocity as usage expands

• Harden security, privacy, observability, and operational runbooks

• Build new marketplace capabilities that unlock liquidity, speed, and better dealer outcomes

• Reduce friction in critical workflows and improve conversion through product-led engineering

• Lead projects that cut across web, mobile, backend, and infrastructure

• Improve delivery predictability through planning, coordination, and proactive risk management

• Mentor engineers and set the bar for pragmatic, high-quality execution

AI-first: what we expect from you

We’re becoming an AI-first business. That means AI isn’t an experiment on the side—it’s part of the operating system.

You’ll help embed AI into:

• Product: smarter workflows, better matching, better quality control, dealer-facing efficiency

• Operations: internal tools, automation, knowledge capture, faster support and triage

• Engineering: AI-assisted development, testing acceleration, improved reviews, quicker iteration

You’ll partner with our AI/BI team to embed intelligence into the platform and marketplace, including:

• Integrating valuation engines into core workflows (pricing, buying, selling, approvals)

• Shipping analytics and insights (vehicle acquisition and disposal performance, liquidity signals, margin drivers)

• Productionising data/AI services: API contracts, monitoring, quality checks, fallbacks, latency and cost controls

• Building internal tools for faster decisions (dashboards, alerts, workflow automation)

You don’t need an ML background. You do need to be comfortable shipping AI-enabled features responsibly and using AI to increase leverage.

Tech stack

• Web: React

• Mobile: React Native

• Backend: PHP (Laravel & Vapor) + Node/TypeScript where it fits

• Database: Postgres

• sCloud: AWS (EC2, RDS, S3, Lambda)

• Delivery: CI/CD, testing, modern development practices

What we’re looking for

Must-haves

• Min 6+ years full-stack engineering experience in production

• Strong PHP/Laravel (non-negotiable)

• Strong React; React Native strongly valued

• Strong Postgres fundamentals (schema, migrations, optimisation)

• AWS experience (EC2/RDS/S3/Lambda)

• Track record leading delivery end-to-end and operating as a senior owner

• Highly organised, proactive, and quick to absorb product + industry context

Wants to work onsite in Sydney (Lane Cove)

Nice-to-haves

• Marketplace / high-growth SaaS scaling experience

• AI-enabled feature delivery (LLM APIs, retrieval/search, automation)

• IaC (Terraform/CloudFormation)

• Testing frameworks (PHPUnit/Pest, Jest/Mocha)

Why this is a strong next step

• The platform is real and growing and your work immediately compounds

• You’ll have leadership scope without being removed from building

• You’ll help shape how we scale and how we embed AI into the business

• You’ll work closely with Product and influence what gets built and why
