Networks look like a puzzle to most people. To me, they're just a problem I know how to solve. What I deliver: Network audits & optimization Design & migration - new builds, office expansion, hybrid/cloud Security hardening - ACLs, segmentation, firewall policies, VPNs Troubleshooting escalations - when your team is stuck, I step in. Root causes, not symptoms. Mentoring / on-call - fractional architect for teams without a full-time role Technical depth: Areas and stack: Routing & switching - Multi-vendor. Security - PFSense, OPNSense, Fortinet, Palo Alto, Cisco ASA/FTD, VPNs, segmentation Linux - Any distro, bash scripting, performance tuning Virtualization - Proxmox, VMware, Hyper-V, KVM Automation - Ansible, Terraform Observability - Zabbix, Splunk, SNMP, syslog Background: 30+ years in the field, 7 as a Cisco Networking Academy Manager and Instructor. I've designed large-scale enterprise networks for government, healthcare, and finance — example a maternity center where downtime isn't an option, campus networks for universities, and an airport-wide wireless solution. I've delivered security projects following both international best practices and local regulatory standards. I've trained and worked alongside engineers across Australia, New Zealand, the US, and beyond, and I learn as much from them as they do from me. I work self-paced, lead or go solo, and I'm still adding tools: Proxmox and Splunk a few years ago, Ansible and Terraform last year. This year I'm diving into AI infrastructure — GPU clusters, distributed training, high-throughput data pipelines. I'm also building deeper into Python and scripting to support automation and development from the ground up. How I work: Clear communication, no jargon. English fluent. Documentation-driven: diagrams, runbooks, handoff notes. Available 20–40 hrs/week. Fixed-price or hourly — whatever fits. Ready to solve your network puzzle? Send me an invite.

Great products begin with a great design that includes considerations for realistic fabrication and assembly. My history of deep involvement with a variety of manufacturing methods allows me to incorporate a long-term vision of the product life cycle throughout the design process. This constant forward-thinking prevents major redesign during the manufacturing phase and ensures projects remain aligned with customer goals. I specialize in 3D mechanical design, analysis and prototyping including: - Design-for-manufacture using: 3D print, CNC machine, injection mold, die cast, sheet metal, laser cut, etc. - Electronics integration - Structural/thermal/vibration analysis - Prototype manufacturing & assembly - Mechanical drawing package creation - Production interfacing I have designed, built and tested successful (some patented) products in the following industries: - Mechanized medical devices - Medical research test equipment - PCB & housing assembly tooling - Aerospace test equipment - Aerospace showroom cabin interiors - SCUBA diving propulsion - Underwater electronics enclosures - Bicycle lights - Photography lights and straps - Mechanized sports training equipment - Small satellite structure & hardware - High-altitude passenger vessel

How to Hire Top Systems Engineers

SYSTEMS ENGINEERS

What is systems engineering? 

Systems engineering is a field of engineering that focuses on the design and management of complex systems. These systems could include anything from SaaS (software as a service) solutions to networks of IoT (Internet of Things) devices.

Here’s a quick overview of the skills you should look for in systems engineering professionals:

  • Systems engineering
  • Systems administration
  • Cloud infrastructure

Why do you want to hire systems engineers?

The trick to finding top systems engineers is to identify your needs. Is your goal to find someone to help you migrate your enterprise web app to a microservices architecture? Or do you require an embedded systems expert to design the PCB (printed circuit board) architecture of your consumer electronics product? The cost of your project will depend largely on your scope of work and the specific skills needed to bring your project to life.

HOW TO HIRE SYSTEMS ENGINEERS

Systems engineers can help you design, maintain, and improve your hardware and software systems.

So how do you hire systems engineers? What follows are some tips for finding top systems engineers on Upwork.

How to shortlist systems engineering professionals

As you’re browsing available systems engineering consultants, it can be helpful to develop a shortlist of the professionals you may want to interview. You can screen profiles on criteria such as:

  • Technology fit. You want a systems engineer who understands the technologies behind your systems engineering project.
  • Project experience. Screen candidate profiles for specific skills and experience (e.g., working with hypervisors such as VMware).
  • Feedback. Check reviews from past clients for glowing testimonials or red flags that can tell you what it’s like to work with a particular systems engineer.

How to write an effective systems engineering job post

With a clear picture of your ideal systems engineer in mind, it’s time to write that job post. Although you don’t need a full job description as you would when hiring an employee, aim to provide enough detail for a contractor to know if they’re the right fit for the project.

An effective systems engineering job post should include:

  • Scope of work: From cloud storage solutions to IoT networks, list all the deliverables you’ll need.
  • Project length: Your job post should indicate whether this is a smaller or larger project.
  • Background: If you prefer experience with certain industries, software, or technologies, mention this here.
  • Budget: Set a budget and note your preference for hourly rates vs. fixed-price contracts.

  1. Identify your project needs, whether it’s database management or network security.
  2. Define the scope of work and write a detailed job post. Be specific about deliverables (e.g., automating business processes with software solutions in an enterprise setting).
  3. Review proposals and shortlist potential systems engineers for unique skills needed to bring your project to life (e.g., Amazon Web Services).
  4. Interview systems engineering talent to gauge whether they’re the right fit for your project.

FAQS FOR HIRING SYSTEMS ENGINEERS

Frequently asked questions

How much does it cost to hire a systems engineer?

Rates can vary due to many factors, including expertise and experience, location, and market conditions.

  • An experienced systems engineer may command higher fees but also work faster, have more-specialized areas of expertise, and deliver higher-quality work.
  • A contractor who is still in the process of building a client base may price their systems engineering services more competitively.

Which one is right for you will depend on the specifics of your project.

How long should you contract a systems engineer to complete your project?

As difficult as it is to estimate how long you will need a systems engineer, budgeting time is very important to keeping your project on track.

Be prepared to budget more time for more-demanding systems engineering projects. For example, designing an architecture for a basic web app will typically take less time than designing a server-side solution for an enterprise web app.

What are the steps involved to hire systems engineers?

Here’s how to hire systems engineering consultants in four simple steps:
