Job Description

Castle Global is a holding company that launches and builds consumer mobile applications for global markets. We have launched Chatous, Kiwi Q&A and Plaza since inception, and we already have 80m+ users across the portfolio. It is still early days here at Castle, and we are looking for lead product manager to set the product direction for portfolio and also help build and lead our product team based in San Francisco and New Delhi.

You’ll be expected to own your space: work with all disciplines on your team to build, launch and iterate. This role is as much about doing individual work, as it is about building an organization where each product manager has complete ownership over products with millions of users. This is a very rare opportunity that will put you in the position of total ownership of the product organization, and launch multiple products without the risk of starting your own company. You will work with your team to drive product decisions, conduct user interviews and market research, and lead the direction of the technical team through your insights into company direction. You will also be able to lead the growth of the company through proven ability to lead it in the right direction and help us build dominant consumer franchises.

This role will expect you to use everything you have learned about building technical products, designing user experiences, and managing a team to drive the growth of a new company. Success in this role means building a product organization that can quickly launch and scale products that are used by millions where the product team is responsible for shaping the vision, direction, and process for making it happen. You will work very closely with senior technical leaders and our director of engineering to take advantage of the myriad of resources the Castle ecosystem provides to make the business successful.


You are a talented product manager with deep experience with consumer and mobile products. Your passion for consumer products is so strong that there is rarely an app that you haven’t tried and analyzed. You are classically trained in product, but you are constantly learning from the best products globally. You have a honed intuition that leads to simple and beautiful solutions, but you have the analytical horsepower to support your intuition with data.

You are an entrepreneurial self-starter that is seeking a bigger canvas to create delightful user experiences.
