👋 Thanks for stopping by and learning more about this role at Sitemate! ✨🏗️

We'd love to hear from you 😊 👩‍💻👩🏽‍💻🧑🏿‍💻👨🏻‍💻

The Full Stack Engineer is an ownership role responsible for product outcomes end-to-end: from shaping technical approaches and building features through to release, reliability, and production performance.

At Sitemate, engineers combine strong technical craft with product thinking and delivery ownership. You'll work in small, high-trust teams alongside Product Design Managers to define problems, shape solutions, implement clean and scalable systems, and take responsibility for what ships — including how it behaves once live.

Engineering, product, and delivery are not separate handoffs here; they operate as one integrated team. We believe the future of product development in an AI-accelerated world belongs to engineers who can think beyond tickets - they own outcomes and deliver at speed with AI.

• Full-time

• Based: Sydney, Australia or Melbourne, Australia

• Remuneration (Including Super): AUD $160,000 - $200,000 pending your experience

Sitemate builds best-in-class software and AI agents for the built world, helping construction, infrastructure and industrial companies work smarter and faster. Our mission is to multiply the engineering power of the built world.

Storm is the #1 data capture agent for the front line of the built world - converting audio, photos and videos into clean structured records.

With conversational support in-app and across SMS, Whatsapp and phone calls, Storm is shifting front line workers from paperwork and clunky digital forms, to natural language and multi-channel data capture.

Our core platforms are Dashpivot (safety, quality and field reporting), Gearbelt (fleet and asset management), Flowsite (no-code integrations), and the Sitemate mobile app for every worker on site.

We have strong product-market fit, generating thousands of new leads per month through word of mouth and organic channels. We are backed by Blackbird, with 200 people across 18+ countries and entities in Australia, the UK, the US and Canada.

Our core values dictate “how we work”. We believe that basic human values such as honesty, trust and integrity are required to simply ‘get in the door’. Our values are designed to help us determine if an already great person, will be a great fit at Sitemate.

You'll lead technical decisions within a team attached to a product. You'll help shape architecture, mentor engineers, and have direct input into how our products evolve to support our users.

You'll work across frontend, backend, and mobile: TypeScript, React, Node.js, Angular, MongoDB, and AWS. You don't need to be an expert in all of these, but you're skilled enough across part of the stack to lead with confidence.

• You'll operate as a product-minded engineer. This goes beyond having opinions about UX. You'll join customer calls, interpret usage data, and make strategic decisions about what to ship and what to defer. The best engineers here understand the customer problem as deeply as they understand the code.

• You'll lead the shift to agentic engineering. We're moving toward a model where senior engineers define and orchestrate AI agents to build features, rather than writing every line. You'll help establish how this works in practice — the patterns, the guardrails, and the quality bar — and help move other engineers towards this workflow.

• Contribute to architecture decisions and long-term technical vision across the platform.

• Build and ship impactful features, from architecting new capabilities to improving performance and code quality.

• Shape experiences around AI-powered developer tools and agentic engineering practices.

• Mentor engineers through code reviews, pairing sessions, and informal guidance.

• Contribute improvements to developer experience (tooling, CI/CD, monitoring).

• Collaborate directly with product, design, and leadership on what to build and why.

• High technical complexity beneath simple UIs — shared components across multiple products, backend services powering web and mobile clients.

• Pace: Fast-Tracked is a real operating value. You'll need to balance speed with quality and sustainable delivery.

• Organisational maturity: engineering leadership, frameworks, and career ladders are being established. You'll be building the plane while flying it.

• You've built and shipped at scale and want to own technical direction, not just execute.

• You're excited about agentic engineering and want to lead a team through that transition.

• You care about mentoring — helping others grow is as important to you as your own contributions.

• You're drawn to real-world impact — our users build wind farms, highways, and mines in 100+ countries.

• You want to shape how an engineering org works through our next phase of growth, not inherit someone else's playbook.

• You want a mature engineering org with a VP of Engineering, established technical ladders, and 50-person platform teams already in place. We're building that — which is the opportunity if you want to shape it, and a mismatch if you need it to already exist.

• You want to specialise in just design or just product management — senior engineers here own the full delivery cycle and operate as product-minded technologists.

• You see AI tooling as a nice-to-have. Agentic engineering is our direction and senior engineers are expected to lead the shift.

• Proven experience building and shipping production software at scale

• Ability to lead architecture decisions and technical direction

• Experience mentoring and uplifting other engineers

• Strong product mindset — thinks about customer outcomes, not just implementation

• Strong enthusiasm for agentic engineering and AI-first workflows

• Deep expertise in TypeScript, React, Node.js, Angular, MongoDB, or AWS

• Mobile development experience

• Experience in a scale-up or high-growth product environment

• MongoDB

• AWS

• React Native / mobile

PLEASE Note:

• We hire directly and don’t work with agencies

• TypeScript / JavaScript

• React or Angular

• Node.js
