We anticipate the project to be long-term — while the initial scope is planned for 6–12 months, we estimate the overall collaboration may extend up to 2 years or more.The recruitment process consists of two stages - a 45 minutes intro call with HR and the technical interview, which takes around 1 hour.That said – we’re looking for someone who’s totally not just into quick MVPs but rather enjoys taking technical ownership and continuously improving a complex product.
