With Williams now expected to retain Valtteri Bottas and Felipe Massa for 2016, Alex Lynn says his plan is to join the F1 grid "within two years."
The Williams development driver has often spoken of his desire to not only step up to a full-time race-seat but also to do so with Williams.
However, with their line-up now expected to remain the same for next season, the 21-year-old says his progress to F1 racer is a two-year plan.
He told Motorsport.com: "At the moment I just need to concentrate, keep my head down. But if I deserve the chance, I'm sure it'll be graned.
"I'm working in the factory almost every day I'm back in England and I feel a real employee of the company. And they take a lot of interest in my career, my results, which is great."
And part of that plan included severing ties with Red Bull and their junior programme, which he did after his GP3 triumph in 2014.
"To be honest, [leaving] was the best option for many reason but mainly it was because I need to get my opportunity in Formula 1 within two years.
"And being with Red Bull wasn't going to allow me to do that.
"And I had a great opportunity coming up with Williams, so that made the decision even easier."
