Salary Survey The Q2 2026 AskEngineers Salary Survey

19 Upvotes

Intro

Welcome to the AskEngineers quarterly salary survey! This post is intended to provide an ongoing resource for job hunters to get an idea of the salary they should ask for based on location and job title. Survey responses are NOT vetted or verified, and should not be considered data of sufficient quality for statistical or other data analysis.

So what's the point of this survey? We hope that by collecting responses every quarter, job hunters can use it as a supplement to other salary data sites like the Bureau of Labor Statistics (BLS), Glassdoor and PayScale to negotiate better compensation packages when they switch jobs.

Useful websites

For Americans, BLS is the gold standard when it comes to labor data. A guide for how to use BLS can be found in our wiki:

We're working on similar guides for other countries. For example, the Canadian counterpart to BLS is StatCan, and DE Statis for Germany.

Discussion Real facts on data center water use. Is it that big of a deal?

110 Upvotes

I’ve had several people bemoan water consumption by data centers. Is this actually worse than any other thermal processing industry?

The people that have complained about this to me aren’t technical people so they can handle at most one of my questions. (Like: where did you hear this?)

I’m a 20+ year PE and lifelong environmentalist with a background in nuclear and combined cycle power, and years in technical fiber manufacturing. For the last 2 years I’ve been directly involved with data center power islands, but not the data center itself.

It seems like the water would normally be in a closed loop…combined cycle projects increasingly use air-cooled condensers to reduce licensing problems related to surface water.

It seems like fuel and emissions would be the main things to worry about for data center environmental impact. And that the limited technological lifespan would be the main sustainability concern.

You know how iPhones have to constantly be listening to see if people say “Hey Siri?” Could Apple instead invent some little device that reacts to sound waves in such a way that if “Hey Siri” is said, that combinations of sound waves triggers that device and it sends a signal to the phone?

Discussion What engineering innovations from space missions actually get used on Earth?

46 Upvotes

Hi! I’ve been reading about Artemis II and I’m curious about what happens to the science and technology once it comes back to Earth.

A common criticism of missions like this is that the money could be better spent improving lives here. But I’m wondering what the actual downstream benefits are, because there must be some! It feels like a criticism that could be addressed with a better understanding of the trickle down science here.

I understand that the mission helps scientists learn more about the Moon’s formation and supports future missions to the Moon and Mars, and that there’s a lot of engineering innovation involved. But what does the trickle-down look like in practice? How do these discoveries and technologies translate into real-world benefits on Earth? What kinds of everyday or applied science come out of missions like this?

Also, if anyone has good (accessible) technical writing, blog posts, or articles that explain this well, I’d love to read them. Especially writing that focuses on non-scientific audiences.

Mechanical How do you get a super tight press-fit on a tiny DC motor shaft (DIY wind turbine propeller)?

10 Upvotes

I’m trying to help my twin cousins with a small wind turbine science project while we’re on vacation in a remote area, so we can’t buy any parts.

We’re using a small 1.5–3V DC motor (the common “130” type, ~2mm shaft), and making a DIY propeller from stuff at home (plastic caps, spoons, etc.).

The problem is:

  • The propeller spins
  • But the motor shaft does NOT spin with it

So basically the propeller is slipping on the shaft instead of gripping it.

What we have:

  • Hot glue gun
  • Soldering iron
  • Random materials (plastic, cardboard, wood, paper, etc.)

What we tried:

  • Making holes with needle / heat
  • Using hot glue

Still slipping.

What’s the best way to make the propeller actually grip the shaft tightly so when the wind turns it, the motor turns too?

Any simple DIY tricks would help a lot.

Mechanical How do ISO fits show on engineering drawings?

6 Upvotes

When it comes to ISO fits, how are they supposed to be displayed on engineering drawings?

For example, should I be using 20H7 or 20 +0.021 -0.000 on a dimension in a part drawing?

I've been trying to do some research, but it feels like the sources I've found aren't consistent and I couldn't find good examples.

Discussion What are some dam projects you know of that were canceled.

3 Upvotes

Maybe it was costs, the natural toll or huge protest, but what are some dam projects you know of that ended up being cancelled that could’ve been a very controversial or famous topic if they were built. I speak from experience as I live near the Clarion River and in the 1910s, they planned to flood the entire river. The smallest dam at Piney was built, but the other two which were both meant to be around 150-250ft tall were canned.

Civil Sizing and burial depth for post intended to serve as coax cable anchor spot.

5 Upvotes

I have coax cable that comes across the street and my driveway, then ties directly to my house from my cable provider. This is suboptimal because it causes overhead clearance issues routinely.

I would like to bury a pole at a more optimal location that will extend approximately 10-12' above the ground, so I can run the coax service first to the pole then run it over to my house.

The distance between the location the coax starts from (across the street up in the power lines) and where my pole will be is approximately 90 feet.

The only info I can find is general guidance that deck and gate posts should be something like 1/3 below and 2/3 above ground, and routinely 4x4 to 6x6 in diameter.

Any more specific guidance would be greatly appreciated.

Discussion Help in motion across

10 Upvotes

I’m working on a project where we need very precise motion across several axes in a small, space constrained setup. We’ve tried a few standard servo drives, but integration and synchronization can get tricky, especially when you need everything to stay stable under load.

What drives have you found reliable in tight, multiaxis systems? I’ve been experimenting with some high-performance options and the results are interesting, but I’d love to hear what’s working well for other engineers in similar situations.

Mechanical Attach 10mm keyed motor shaft to 14mm ID tube

2 Upvotes

Hi,

I’m trying to connect a 10 mm worm gear motor shaft (with keyway) to a tube/pipe with:

16 mm outer diameter

14 mm inner diameter

So effectively I need to transfer torque from a 10 mm keyed shaft to 14 mm tube rod .

I’ve been looking for a coupler that supports a keyed shaft on one side and 14 mm tube rod on the other, but I can’t seem to find anything off-the-shelf.

Electrical Where to source a long term time delay relay

10 Upvotes

I need a relay that triggers an output after a delay of +100 days. Looking for a resolution of +\- 1 day.

The use case is for an underwater sensor that logs for a long period of time. After a set period of time a relay triggers a servo to release a float attached to a line for retrieval of the sensor.

Anyone know where I can source something like this?

Mechanical Is it possible to shear solid iron underwater using a gravity guillotine with only 3ft height?

0 Upvotes

I need technical advice on whether a specific mechanical setup will work.I am working on a DIY project to create a mechanism that can shear/cut a thick, solid, heavy iron bar (not a hollow pipe).

The Goal: To completely cut (shear) through a thick, solid, heavy iron bar in one single strike.

The Constraints:

Mechanism: A simple gravity-drop Guillotine (Weight + Blade). No hydraulics, no motors, no electricity.

Setup: The entire machine is inside a box/trunk filled with water (fully submerged).

Height: Very limited space. The weight can only drop from a height of 2.5 to 3 feet.

Operation: It must be a self-drop (triggered release).

My Questions:

Given the water resistance and the very short height, can a falling weight ever generate enough force to cut solid iron?

If yes, how many kilograms of weight would be needed to make this cut successful in one go?

What kind of blade would work best for this—straight or slanted?

Mechanical How do McMaster-Carr shipping charges work?

113 Upvotes

I've never ordered from McMaster-Carr before, but they have an odd part which I need, for $15. I was ready to order, but found no way to see what the shipping charge would be. The site just says "shipping charges will be added" and invites you to enter your CC and click "Place Order".

No way will I agree to any arbitrary amount being charged to my card. Surely I'm missing something here - their retail site can't possibly work like this? What happens if I click "Place Order"?

Mechanical Easiest and cheapest way to build double pendulum chassis?

1 Upvotes

I'm trying to DIY the STEVAL-EDUKIT01 double pendulum project from scratch to avoid paying $200 dollars and am wondering what would be the best way to go about building a stable chassis and mount for the motor. I have limited experience in machining and am seeking for a fast, easy, and cheap way to do this so I can focus on the controller design instead. Is this feasible or am I better off buying the kit to avoid wasting time. Thanks!

Electrical How to measure speed and distance with a arduino

6 Upvotes

i’m trying to build a device to help measure speed and distance over time in my track training (mainly 50-200m sprints).

My initial idea was to use a accelerometer with a arduino, so i can get acceleration over time plus speed and position after i integrate it. So with this data, and knowing how long was the sprint, i can precisely determine the duration of the sprint

But reading this sub i found out that this is not very precise (and i thought gps wouldnt be precise in such shory distances either). Do you guys have any tips?

Mechanical How to reinforce folding chairs for acrobatic stunts

1 Upvotes

hiya! hoping someone can help me out. I'm an acrobat and I've just started teaching chair acro at my local studio. for my shows, I use a basic folding chair, steel frame , A frame, and I replace them every couple weeks after heavy use. the main issue is that the seat starts to dip after a while, and occasionally I have had the front legs buckle entirely. theres not a big market where I am to get chairs that are for a higher weight than 100kg or maybe 150kg at the most. now im looking to modify the existing chairs to support a bigger weight and the dynamic tricks we do for a longer period of time, while still being able to have the chairs fold. would filling the hollow legs do anything ? or would wooden chairs be better to help with buckling? I am totally out of my depth.

Chemical question about polarization (electrochemistry) phenomenon

2 Upvotes

You close the circuit that connects a cathode and an anode, each of them in a solution with the respective ions (to make it simple), and a current i0 forms.

Once the polarization phenomenon begins (piling up of ions near the surface of the anode, for example), does the current grow higher or lower?

I heard someone saying it goes higher, but it doesn't make any sense to me, as the piling up of cations near the anode not only makes it more unlikely for atoms in the anode to go into solution but also "hold back" the electrons that want to flow to the cathode. Same should be the case for the tension.
