In a nutshell: By helping develop beneficial technologies faster, and deploying existing technologies in new and important ways, engineers — by which we mean all kinds of engineers other than software engineers, which we cover separately — can help contribute substantially to solving some of the world’s most pressing problems.

How can engineers best make a difference?

Many potential solutions to the top problems we recommend working on include developing and deploying technology — and this often needs engineers.

Below is a list of pressing global problems and how engineers can help with each.

If you’re an engineer, you can read through to see if any of these issues appeal to you — and then aim to speak to some people in each area about how your skills could be applied and what the current opportunities are.

Preventing catastrophic pandemics

A future pandemic that is much worse than COVID-19 could pose a significant risk to society.

This is one of our top recommended areas, and has a clear need for engineers, as argued in Biosecurity needs engineers by Will Bradshaw.

While there is a key role for bioengineers and chemical engineers, physical engineers are also needed. Materials or civil engineers could:

  • Help design physical protection from pathogens, like more effective or more affordable PPE (personal protective equipment) such as gloves and masks, better pathogen containment systems for labs, and systems to reduce pathogen spread in buildings or vehicles.
  • Help improve technologies for monitoring pathogens, like systems for sampling environments and processes for managing and examining samples.

AI alignment

We expect AI hardware to be a crucial component of the development of AI. Given the importance of positively shaping the development of AI, experts in AI hardware could be in a position to have a substantive positive impact.

Improving civilisational resilience

One very neglected way to reduce existential threats is through generally increasing the resilience of our society to catastrophes.

Engineers can play a big role in this issue by developing alternative foods, refuges, and knowledge stores that will be able to survive a near-apocalypse.

For instance, David Denkenberger is an engineer developing alternative foods that could be rapidly scaled up in the event of a global famine, perhaps caused by nuclear winter or a major volcanic eruption. We have two podcasts with him:

To learn more about refuges, see this review by Open Philanthropy. Or learn about how to increase the chance of recovery from a catastrophic event in two of our podcast episodes:

Fight climate change

We think developing and rolling out green energy is one of the best ways to tackle climate change, and engineers have a major role to play in this.

You can further increase your impact by focusing on technology that’s not widely known (e.g. hot rock geothermal) or unsexy (e.g. decarbonising cement rather than developing electric cars).

We have more notes on how to most effectively tackle climate change. We’d also recommend What can a technologist do about climate change? by Bret Victor.

Other problem areas that need engineers

In addition to the top problems mentioned above, there are many other areas where engineers are needed. For example, you could:

Options outside engineering that can use engineering aptitude

Engineers often have a systems mindset that can make them a particularly good fit for operations management or entrepreneurship. If that work interests you, it’s worth considering whether to retrain and try to make a transition.

Some engineers may also excel at other options that require good quantitative ability, such as:
