I first started as a standard Design Engineer working to create new products determined by market needs or feedback from the sales team. While in this role I was able to work on NNN NNN NNN that was released.
After N months working there I switched over from assisting with custom projects part time to being a full time member of the customs team. The role involved creating custom solutions which can involve coordinating and sourcing custom components, creating instructions for production to manufacture the custom product, creating technical documentation for the products, and occasionally assisting shipping with safely packaging the product. I found it very fun to get to dive into a product that would get used for one customer because it allowed for a much more focused product. These solutions were very project specific which meant I could focus on the customer specific problem without having to worry about possible general market customers.
