Life as an IT Technician at Lanrex: Enterprise IT from the Inside
Since October 2025, I've been working as a Technician at Lanrex, a managed services provider based in Macquarie Park, NSW. It's been one of the most practically educational roles I've had — and it has significantly shaped how I think about enterprise IT, cybersecurity, and client service.
Here's an honest look at what the role actually involves.
What Does a Technician at an MSP Actually Do?
The short answer: a lot of different things, often in the same day.
Lanrex provides IT infrastructure and support to enterprise clients, which means the scope of work is broad. On any given day I might be imaging and configuring devices in the morning, troubleshooting a remote client issue in the afternoon, and updating asset inventories in between.
The variety is one of the things I appreciate most about the role. It keeps problem-solving sharp and prevents the kind of tunnel vision that can develop when you're deep in a single technology stack.
Device Deployment at Scale
One of the core responsibilities has been orchestrating large-scale device deployments using the Microsoft Deployment Toolkit (MDT). This means setting up standardised images, configuring deployment shares, and pushing consistent builds across hundreds of machines for enterprise clients.
The challenge here isn't technical complexity in isolation — it's consistency and accuracy at scale. Every device needs to be correctly imaged, named, joined to the right domain, and configured with the right software before it reaches an end user. A systematic approach is non-negotiable.
Key things I've learned doing this at scale:
- The importance of building and testing images thoroughly before deployment
- How to handle exceptions and edge cases without derailing the broader rollout
- Documentation as a first-class part of the process, not an afterthought
Remote Management and Cybersecurity
Beyond physical deployments, a significant part of the role involves remote management of client environments using N-able. This includes monitoring device health, pushing software updates, applying security policies, and responding to alerts.
This is where the cyber security side of my education becomes directly applicable. Understanding endpoint security, patch management, and the risk profile of different configurations isn't theoretical — it directly informs how I manage client environments.
Some of the cybersecurity work involves:
- Ensuring client devices have appropriate protections in place
- Identifying and remediating security gaps in endpoint configurations
- Supporting clients through security-related issues with clear, calm communication
Being the Technical Point of Contact
One aspect of the role I didn't fully anticipate was how much of it involves direct client communication. When something breaks — and things break — clients need fast, clear answers. I've had to develop the ability to translate technical problems into language that makes sense to non-technical stakeholders, while simultaneously working on the fix.
This customer-first mindset is something Lanrex takes seriously, and it's something I've internalised: technical correctness means little if the person you're supporting doesn't feel heard and helped.
Asset Management and Documentation
IT asset management isn't glamorous, but it's foundational. Part of my role involves generating and maintaining comprehensive IT asset lists — tracking device lifecycles, recording configurations, and ensuring clients have accurate inventories.
Good documentation is the difference between a well-run IT environment and one where nobody knows what's deployed where. I've come to genuinely appreciate its importance.
Balancing Work and Study
Running this role alongside a full-time CS degree at UNSW has required deliberate time management. But the overlap between what I study and what I practise at work has made both more effective. University gives me the theoretical frameworks; Lanrex gives me the reality checks.
If you're a CS student wondering whether to work while studying — especially in a technical role — I'd strongly encourage it. The practical application accelerates understanding in ways that coursework alone can't replicate.
What's Next
I'm continuing to develop my skills in enterprise IT management, remote monitoring, and cybersecurity. The intersection of these disciplines — particularly as organisations increasingly face sophisticated threats — is where I see the most interesting work happening.
The role at Lanrex has given me a strong foundation in how enterprise IT actually operates. That context is shaping how I think about the problems I want to work on next.
