I'm the founder of Version One Labs (look me up on LinkedIn) and I want you to work with me on an interesting new idea!

I was previously Director of Engineering at Crunchbase, led product and engineering at Oncue (venture-funded B2B SaaS) and have built products at multiple bay area startups. I run a product development studio, Version One Labs, that works with startups here in California. The website is a bit out of date but I’m currently working with a few exciting startups to help them with their product dev efforts.

This role is for a different mission though. I am currently in the early stages of building our first internal product and am looking for 2-3 scrappy, driven, and sharp developers who are interested in working on exciting ideas and build products from the ground up. 

You will learn a lot in the process.  If you have startup dreams of your own and are interested in some day doing your own thing, I strongly believe this experience + the wealth of knowledge I can share with you could be invaluable for you.

Here's what I'm looking for:

- you must be highly proficient with React (typescript, redux etc etc) or Rails (strong database design, clean code, and API building skills). I will check for your fluency with both.

- you enjoy the process of building something from scratch and don't require a ton of hand holding, i.e., you are self-driven

- you like the autonomy and freedom of working on early stage stuff and can manage your own time (I don't boss around and like working with people who I don't have to manage too much)

- you have utmost integrity (tell me what you don't know and deliver what you say you will, when you say you will)

- you are willing and open to new ideas and are a fast learner

If this is appealing to you, please apply. I respond quickly.
