Profitable Freelance Niches for Engineers

The following 3 niches were the most profitable hidden niches for freelance engineers:

  • 3D printing
  • Robotics
  • Technical blogging

These three niches are great because the work is steady, and the pay is well above average. Fees can range from $200-$800 per job, depending on the difficulty and time required to complete it.

Tips to Become a Freelance Engineer

Upwork, where you can bid on projects and earn money for your skills. It's a great place for new freelancers to start earning money online.

  • Measure Twice, Cut Once: When you're new to freelance engineering, it can be difficult to know exactly how much work you should take on. Upwork has a minimum that you're required to reach per week in order to keep your account active, so it might seem like a good idea to accept as many jobs as you can once you get started.
  • Not Too Many Projects: It can be tempting when the jobs are rolling in to accept every single open project that comes along. Resist the urge! You will quickly burn out if you take on too much work at one time. There is no way that you'll be able to meet deadlines for all of those jobs if you take them on at once.
  • Be Flexible: If you have multiple clients who need their projects done at the same time — or even worse, overlapping — it can be difficult to figure out how they'll all fit into your schedule and still make enough money to pay the bills at the end of the month. Prepare yourself by being flexible with your schedule and always planning ahead

Freelance Engineer Profile Description Example

I'm a freelance engineer with over 6 years of experience. I've worked across many industries including health care, hospitality, and retail, and I've helped businesses of all sizes solve their most challenging problems.

I'm a self-starter who works best independently, but I can also collaborate well on teams. When working with my team members, I take the initiative to lead the design process and offer clear direction. I'm always open to feedback and receptive to new ideas.

What do you do?
I like to say that I build other people's dreams. My favorite thing is to come up with a crazy idea for some software or hardware system, then actually build it. It's incredible how much we can do these days with increasingly sophisticated technology!

Why should we hire you?
I'm a big picture thinker who loves to design the entire project from start to finish, from requirements gathering through development and testing and into deployment. I've been doing this for years, so you won't need to worry about me needing hand-holding or getting stuck on something minor if there's a bigger problem at hand.

How to Update a Engineering Project Status?

As a freelance engineer, you know that keeping your project status up to date is important. But if you're new to freelancing, it can be hard to figure out how to keep your project status updated.

First, check in with your client or employer. Ask them what they want the status of your project to be. For example, if you were working on a website redesign for a client and they wanted to see progress being made every week, you'd update their project status as "in progress," but after every week when you'd send over drafts of pages or designs, they would update their project status back down to "in progress."

If your client doesn't have any specific preferences about how often they need updates from you, then just make sure that at least once a week (or whatever interval makes sense for the type of work)

Freelance Engineer Narrative

I have been working as a freelancing engineer since 2016. Since then, I have worked with clients in the US, UK, and Canada.

I started working as a freelancer because I was not getting enough work as an employee at my previous job. I was looking for ways to get more experience in my field of expertise and better pay, so I decided to take the leap and start working as a freelancer.

I think the biggest challenge when starting out was finding clients who would be willing to work with me as a freelancer instead of an employee. Luckily, there are many websites where you can post your profile and start contacting potential clients (such as These sites usually have systems in place that help match up freelance engineers with potential employers, which makes it easier for both sides to find each other.

As far as advice for people thinking about becoming freelancers themselves, I would say it's important to be very clear about what kind of projects/tasks you can take on before agreeing on payment terms with clients. This way both parties know what they're getting into before they sign any contracts or agreements together!
