https://www.privy.io/careers#open-positions

Hi, I'm Asta, CTO at the identity and wallet infra startup Privy. We build a wallet and digital asset API that over a thousand companies integrate in order to onboard (75M+) users onto products built with blockchain infra and distributed systems.

We solve hard product design and security problems in order to shift the status quo around digital ownership and protect the accounts and assets of millions of users. With our work, we stand to transform how users think about asset ownership and money movement online.

We're a small, high-ownership team building a product with incredibly scaled usage (>12M MAUs, massive transaction volume). We were recently acquired by Stripe — while we'll remain an autonomous team and stand alone product, joining Stripe will help significantly accelerate our growth and impact.

Roboflow | Solutions Architects, Implementation Engineer, Developer Advocate, Full Stack Engineers | Full-time (Remote, SF, NYC) |
https://roboflow.com/careers?ref=whoishiring0725

Roboflow is the fastest way to use computer vision in production. We help developers give their software the sense of sight. Our end-to-end platform [1] provides tooling for image collection, annotation, dataset exploration and curation, training, and deployment.

Over 1 million engineers (including engineers from 2/3 Fortune 100 companies) build with Roboflow. We now host the largest collection of open source computer vision datasets and pre-trained models [2]. We are pushing forward the CV ecosystem with open source projects like RF-DETR [3] and Supervision [4]. And we've built one of the most comprehensive resources for software engineers to learn to use computer vision with our popular blog [5] and YouTube channel [6].

We have several openings available but are primarily looking for strong technical generalists who want to help us democratize computer vision and like to wear many hats and have an outsized impact. Our engineering culture is built on a foundation of autonomy & we don't consider an engineer fully ramped until they can "choose their own loss function". At Roboflow, engineers aren't just responsible for building things but also for helping us figure out what we should build next. We're builders & problem solvers; not just coders. (For this reason we also especially love hiring past and future founders.)

We're currently hiring for full-stack engineers to help build our product, field engineers that work directly with our customers to solve their business needs with computer vision, and several technical roles on the sales team.

We raised our Series B round at the end of last year, led by GV. With this round, we will continue building the open source tools, platform, and community so developers and enterprises can deploy computer vision applications to production. [7]
