About Mixer

Mixer is not your traditional venture builder. We build and scale digital ventures, in partnership with forward-thinking global enterprises. We work with a handful of strategic partners to access their 'unfair' advantages to de-risk the ideas and businesses we back. These include banks such as Barclays, and technology firms such as Amazon.

About the Role

We're looking for a full-stack Developer who wants to join a new start-up for a new exciting project: Saathi. Saathi is a new fintech venture being incubated by Mixer (Incohare Ventures Limited), a startup venture development platform.

1 month fully paid starter internship to get settled and prove experience. Post-internship, job offer with 3 months probationary period.

About the company

Saathi means ‘Partner’ and we want to be a financial partner to employees, 50% of whom are living paycheck to paycheck and just help them make the step up from survival to a more balanced financial health. Sorting out financial issues does result in taking away stress, improving focus and showing that a company cares about it’s workforce in every way. We hope you will partner with us to bring this vision to others.
