Scale AI | Product Security Engineer | TypeScript, Node, Python, AWS | Full-time | Hybrid in San Francisco, CA or NYC or Remote

This is for a team that I'm working closely with and helping grow. We're hiring for somebody with a hybrid SWE and Security background to help scale up the team.

It's currently one engineer who's got a ton on his plate, so the ideal person for this role is somebody who's interested in learning, digging in deep to fix issues (especially shipping PRs), and helping shape the future roadmap of the team. It is not an analyst role.

The role is primarily targeted at mid-career folks with a few years of experience (2+ years minimum). Those that are Senior/Staff level folks, especially those with a strong SWE background that are curious about security, are encouraged to apply if this role resonates strongly. (I personally transitioned from SWE -> ProdSec, years ago, and several other folks on the broader Security team have non-Security backgrounds too.)

Here is the role: https://scale.com/careers/4602047005

Feel free to apply there, email me with you resume (on my profile), or add me on LinkedIn[0]. I'll try my best to answer questions and reply to everybody, but sometimes there is so much inbound that it isn't possible. Thanks!

Zed Industries | North America, South America, Europe REMOTE | https://zed.dev/ Zed is a company for developers, by developers. All 3 of our founders have spent years in the trenches writing software and still do it almost every single day. We know the only way to build the world's best code editor is by equipping every single member of the team to do the best work of their career. We've raised $42M to support our ultimate vision, a new way to collaborate on software, where conversations about code remain connected to the code itself, instead of being tied to aging snapshots or scattered across different tools. The first step was creating a high-quality editor to serve as the user interface. Now this new investment lets us expand to tackle the next phase of our plan. We're developing a new kind of operation-based version control that incrementally tracks the evolution of your code with edit-level granularity, and we're integrating it into Zed to make collaboration, both with agents and teammates, a first-class part of the coding experience.
