How it works
Engineers register a profile listing their discipline, software skills, certifications and project history. Clients, usually engineering firms, contractors and asset owners, post needs or ask Trees Engineering to staff a scope of work. Some projects are matched directly to individual freelancers. Others are run as packages, where Trees Engineering coordinates a team to deliver drawings, calculations or studies.
Work is often remote, such as design reviews, studies and documentation. Some roles may require site visits or local presence, so read each project’s location requirements.
The kind of work on offer
Typical tasks in these industries include electrical load studies, cable sizing, piping and instrumentation diagrams, equipment datasheets, 3D model checks and technical documentation. Renewables projects may involve solar or wind design support. Marine and offshore work often needs specific standards and certifications.
Pay
Trees Engineering doesn’t publish freelancer rates or fees. Engineering rates depend heavily on discipline, seniority and region. Agree your rate, payment terms and any platform margin in writing before you start.
Building a strong profile
List your engineering software, such as AutoCAD, ETAP, SmartPlant or similar tools, along with the codes and standards you’ve worked to. Name the project types you’ve delivered and your role on each. Clients in these industries hire on proven experience, so specifics matter more than general claims.
Common mistakes
Some engineers list broad skills without project evidence. Others accept packages without checking which standards apply. Confirm scope, deliverables and review cycles before starting.
Communication on engineering projects
Engineering clients expect clear technical communication. Confirm the codes, revision status and deliverable format at the start. Log assumptions in writing, and send drawings or calculations with a short note on what changed. Clear handovers make clients more likely to bring you back for the next package.
Is it worth it?
For experienced engineers who want freelance or remote work between contracts, it can be. The niche means fewer, larger projects rather than a steady stream of small gigs, so keep your profile current and your CV ready.
Keeping track
Note which projects came through Trees Engineering, your rate on each and how long payment took. That record helps when you negotiate your next rate.
Getting repeat work
Engineering firms prefer engineers they already trust. Deliver clean, checked work on the first package, and you’re more likely to be asked back when the next phase starts. A short close-out note listing what you delivered helps the client remember you.
Final tip
Add any professional registration, such as chartered status, to your profile. It’s a quick trust signal for clients in regulated industries.
Owen’s take
Trees Engineering is a rare niche option for industrial engineers who want freelance work. It won’t suit general freelancers, but for qualified engineers it’s worth a profile.
Who it suits
It suits experienced electrical, mechanical, process, instrumentation and civil engineers in energy and heavy industry. It suits less well junior engineers without project history, or freelancers outside engineering.
Getting started
Register as an engineer, complete your profile with disciplines, software and past projects, and upload your CV. Keep your availability current so the team can match you when projects come in.
