Lead Data Engineer | Azure Enterprise Data Platform

Most organisations talk about AI. This business is investing in the data foundations that actually make AI possible.

If you've ever wanted the opportunity to build an enterprise data platform the right way, rather than inherit years of technical debt, this is a rare chance to shape its future from the ground up.

I'm partnering with one of Australia's most respected organisations, with more than 50 years of success and a significant investment underway in Data, AI and modern engineering capabilities.

As Lead Data Engineer, you'll lead one of the organisation's most significant technology transformations. Today, critical business data lives across multiple legacy systems that don't seamlessly connect. Your role will be to bring these disparate data sources together into a modern, centralised enterprise data platform, creating a single source of truth that enables better business decisions, trusted reporting, and the data foundations required for AI and advanced analytics.

This is a genuine leadership opportunity for someone who enjoys remaining hands-on while influencing architecture, engineering standards and the long-term technology roadmap.

What you'll be doing

• Lead the transformation of multiple disconnected legacy systems into a modern, centralised enterprise data platform.
• Design and build a modern enterprise data platform using Microsoft Azure technologies.
• Develop scalable, production-grade data pipelines using Azure Data Factory and Azure Databricks.
• Define enterprise data architecture, modelling standards and engineering best practice.
• Establish DataOps processes, CI/CD pipelines and platform governance.
• Partner with architects, software engineers and business stakeholders to deliver data solutions that create real business value.

What you'll bring

You'll ideally have:

• Proven experience leading the design and delivery of enterprise-scale data platforms.
• Strong hands-on experience with Azure Data Factory and Azure Databricks.
• Experience designing and delivering enterprise-scale data platforms.
• Deep knowledge of ETL/ELT, SQL and modern data modelling.
• Experience implementing DataOps, CI/CD and modern engineering practices.
• Strong stakeholder engagement skills and the ability to influence technical direction.

Experience with Microsoft Fabric, Azure Synapse, Spark or other modern cloud data platforms would be highly regarded, but isn't essential.

Why this opportunity?

• Lead one of the organisation's most significant technology transformations.
• Build a centralised enterprise data platform that becomes the single source of truth for the business.
• Influence architecture, engineering standards and technology decisions from the ground up.
• Work alongside a growing AI & Innovation function shaping the organisation's future.
• Enjoy genuine ownership, autonomy and the opportunity to leave a lasting technical legacy.

If you're looking for the opportunity to solve complex engineering challenges, modernise legacy platforms and build the data foundations that will power AI across the business, we'd love to hear from you - apply now!

Finance & HRIS Platforms Lead — Melbourne — $170,000 + super

Platform leads carry the technical depth to run an entire organisation's systems. Most are still asking permission to make a routine call. Why?

Here, you'll earn $170,000 + super, plus an extra week of annual leave on top of standard entitlements, and free tickets to major sporting events throughout the year, if you're into that kind of thing. 

But it's not just the money or the perks. In this role, you're not the person who implements what's been decided elsewhere, you're the person deciding. 

Access controls, testing and release practices, what gets simplified, automated or replaced across the platform stack: that's yours to call, not yours to escalate. 

Your experience stops being something that executes someone else's roadmap and starts being what actually sets it.

This is a well-known national organisation pulling HR, Finance, CRM, Performance, and Cloud platforms out of silos. 

You'd own the Finance & HRIS side specifically: think Workday, TM1, Cognos, Concur, D365 or similar, plus the integrations that connect them.

If you stayed where you are, you'd likely still be running the same platforms under the same constraints in a few years' time, waiting on the same approvals. 

Move here, and you'd have spent that time rebuilding a fragmented five-platform environment into one coherent, modern stack, with your name on the decisions that got it there, and the results to point to.

That matters for where this goes next. This organisation is growing, and platform unification is only the start of it, the trajectory from here is toward a Head of Technology remit, for the person who actually owns this transformation rather than just maintains it. 

You're not applying for a support role with a ceiling. You're applying to be the one who builds the case for what comes after this job, because you'll be the one who can prove it worked.

You'd also have people actively wanting you to push. 

Senior leadership is driving AI-enabled ways of working and backing people who'll challenge a comfortable, long-tenured status quo. If you've spent years trying to modernise a legacy stack while everyone around you quietly defended it, that's not a battle you'll have here.

Good fit if you've got 8+ years across Finance/HRIS platforms and business process/data management, strong hands-on systems administration experience, and a track record of fixing the actual problem rather than the symptom.

Send your CV through, or me a message, happy to talk specifics before anything formal.

We need an Architect.

Not an assessor.

Someone who can shape architecture patterns, work through technical trade-offs with developers, and help engineering teams move faster while maintaining strong security guardrails.

This role sits at the intersection of Architecture, Engineering, Security and AI.

You'll help build platforms that support large-scale AI and agent-based workloads, while defining secure, repeatable patterns that simplify delivery rather than create friction.

You could come from a software engineering, platform engineering, cloud architecture, solution architecture, or security architecture background, but you'll need a strong understanding of how modern platforms are built and delivered.

Working closely with engineering teams, you'll design secure AI and cloud-native solutions, influence platform decisions, embed security into delivery pipelines, and establish architecture patterns that can scale.

We're looking for someone who can balance security, engineering, and business outcomes, and who understands that architecture is as much about enabling delivery as it is about managing risk.

If your experience has been primarily focused on governance, compliance, or architecture reviews, this probably isn't the right fit.

A high energy and outcomes focused consulting firm is bolstering their data engineering capability with a hands-on technical senior to drive platform delivery on a significant government sector engagement. You'll spend your time between the keyboard and the whiteboard: designing production data pipelines, mentoring 2–3 junior engineers, and helping drive technical direction for client deliverables across the Azure, Databricks, and Snowflake stack.

Day to day, you'll be designing and owning production data pipelines and platform components across Azure, Databricks and Snowflake, doing hands-on engineering rather than just oversight, while helping guide the technical direction for client engagements. That means making the calls on architecture, modelling approach and tooling trade-offs, and documenting them clearly enough that clients can run the platform without us. You'll apply and uphold our engineering standards around testing, CI/CD, security and maintainability, and mentor a team of two or three engineers by reviewing their designs and code and lifting the bar for what we ship. Alongside the technical work, you'll scope engagements with clients, manage delivery plans, translate business problems into technical solutions, and support business development through discovery, estimation and proposals.

You'll likely have five to seven years of hands-on data engineering behind you, with a track record of shipping production platforms rather than stalled migrations or prototypes. We're looking for deep expertise across Azure, Databricks and Snowflake.

Just as important is the way you work. You're someone who can guide delivery and people while staying hands-on, communicate clearly with non-technical stakeholders, and thrive in a consulting environment with shifting context, multiple clients and direct client contact. Australian citizenship is preferred, but no security clearance is required. Azure Data Engineer or Databricks certifications, streaming and real-time data experience, AI/ML enablement, or a consulting background would all be welcome bonuses.

A hybrid setup, with one or two days a week in the office or on client site and the rest from home, paid professional certifications, and a real opportunity to shape the engineering culture from within.

If you've shipped platforms on this stack and want to stay hands-on while mentoring a small team, apply or get in touch: ronny@theonset.com.au.

Staff Site Reliability Engineer - $300k (base + super + bonus), Sydney - 2 Days WFH

You join the team.

You learn the systems. You find the problems. You write the docs.

You give the talk, but nobody listens.

3am pages. Same alert. Different week.

You know the fix. It's just not prioritised.

You're a Staff SRE. You've got the answers. You've got the experience.

You're just not being asked to use them.

Most experienced SREs reach a point where keeping systems alive stops being the challenge.

What's exhausting is watching the same reliability problems repeat, because nobody prioritises the work that would prevent them.

As the foundational Staff SRE here, it would be different.

You're not here to own incidents. You're here to eliminate the reasons they happen.

The hiring manager's view is that reliability has no shortage of good ideas, they're just rarely prioritised.

This role exists to change that.

You'll have genuine influence over OKRs, engineering standards, and how reliability is measured across an organisation of 1,500 engineers.

That's not a common thing to be offered.

This is their first Staff SRE hire.

That means you'll define what the role means inside one of Australia's largest engineering organisations.

The impact you need to reach Principal is here.

You'll also shape their Agentic SRE strategy. AI applied to incident detection, diagnosis, and remediation. Not a pilot. In production.

For engineers who want to understand where the discipline is heading over the next decade, joining now means building that experience rather than reading about it in someone else's case study.

If you've been doing strong Staff-level work but feel like you're spending more time firefighting than fixing things, then send me a message.
