Voice acting career
Zieja's voice acting career spans video games, animation, and commercials. In 2012, he submitted a fan song called "Not The Taxi You Whistled For", a whistling cover of the song "Farm Boy" from Final Fantasy VII, winning the contest, which helped him get into voice acting.[4]
In 2013, while still in a government role, he began taking on small voiceover projects,[5] and by 2014 had transitioned to full-time voice acting, recording from his home studio before relocating to Los Angeles.[6] According to Zieja, he turned to voice acting after his military intelligence job burned him out, calling that work "a lot of PowerPoints." Within eight months, his client list had grown long enough that he needed to quit his day job and focus on voice acting full-time.[7] He has voiced Fox McCloud in the animated short Star Fox Zero: The Battle Begins (2016), Claude von Riegan in Fire Emblem: Three Houses (2019) and related titles such as Fire Emblem Warriors: Three Hopes (2022) and Fire Emblem Heroes, Bumblebee in the Netflix series Transformers: War for Cybertron trilogy (2020–2021), Achilles in the English dub of Fate/Apocrypha, and Wriothesley in the video game Genshin Impact (2023).[2][8] He plays the male version of the protagonist, Wolf, in Destiny: Rising (2025).[9]
Along with voice acting, Zieja's whistling has been dubbed in over 30 different pieces of media since 2025, including Fate/Apocrypha as Achilles idly whistles, and in the 2025 film Superman as Clark Kent whistles for his dog.[10]
