Fast-paced and lots of exposure, but long hours and a sink-or-swim culture

Forward Deployed Software Engineer • Current Employee

Pros: A very agile and action-oriented environment. FDEs are encouraged to find a need in the project and develop their own slice of it. Resourcing responds to this by moving you to other projects that can best make use of the spike you've demonstrated in the process. You can quickly build on Foundry. Tackling technical problems at a high level means you get a huge amount of exposure to different problem spaces.

Cons: It can be a very sink or swim environment. It's also not as technical as your usual software engineering roles, as you're generally building on top of Foundry, which is already a well-built-out platform. Depending on your project, you can be frequently working long hours.
