After the Terry Colby hacking scandal, Wellick was appointed Interim Chief Technology Officer at Evil Corp. As CTO, Wellick relays the Evil Corps technology strategy to investors, supervises software development processes, and identifies platforms for delivering services. A visionary, he has also laid the foundations for new security protocols and measures. The Evil Corp job is a position he intends to make permanent, no matter who he has to impress or suppress to achieve this goal. His partner in social climbing and career mobility is his wife, Joanna, who goads him to more aggressive action and darker schemes. While Tyrell depends on their partnership, he also struggles to find his own path. When his interest in Elliot collides with his professional mission, Tyrell must choose whether to follow Joannas plan or take matters into his own hands.
