We've raised $87m from top-tier investors to pursue this vision. We're growing very quickly and have major, household-name financial institutions as clients and investors. We're working on hard, interesting problems and want to push the boundaries of what's possible for AI-driven products. We're hiring for many engineering roles in NYC and SF, including:
- Full Stack Engineer, Senior + Staff ($190k-270k)
- Design Engineer, Senior + Staff ($190k-270k)
- Staff Frontend Engineer ($235-270k)
- Applied AI Engineer ($200k-275k)
- Cloud Infrastructure Engineer ($175k-250k)
- Forward Deployed Engineer ($190k-250k)
- Quality Engineering Lead ($130k - 185k)
We're also hiring for many non-technical roles. The best way to apply is online on our website (we review every application!). Full list here: https://jobs.ashbyhq.com/norm-ai?utm_source=7ow8wN5o3g.
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!

We're an early-stage startup looking for someone passionate about detection engineering and generative AI.
If you know SIEM, threat intel, logs, detection modeling/strategy, purple teaming, and adversary emulation — and you've been wanting to explore how LLMs/agents can accelerate detection engineering workflows — we'd love to talk.

Enterprises are drowning in unstructured documents and outdated workflows; we see a massive opportunity to build the next big enterprise automation platform to transform how work gets done, starting with commercial construction.
Join now and be at the ground floor of a pre-seed startup with strong momentum already in place: signed design partners, a clear product north star, and product development underway. You’ll be building alongside a team of ex-Salesforce leaders/operators with prior exits and 0→1→Salesforce-scale experience.
What You’ll Do:
- Help architect, build, and ship our core platform.
- Collaborate directly with design partners to validate and iterate quickly.
- Influence product strategy, technical direction and architecture from day one.
Who You Are:
- We’re looking for someone who thrives in ambiguity, moves fast, and thinks boldly.
- You’ve shipped products for 3 years at least and yearn to continue learning everyday growing yourself, the product and the team.
Ideal background includes two or more of the following:
- Data, enterprise SaaS, or startup experience
- Full-stack engineering with equal comfort across both frontend + backend
- AI/ML expertise
Tech Stack:
- SvelteKit, Tailwind, DaisyUI, Postgres, and Supabase

We are an early-stage, well-funded startup making humans and computers work together more efficiently. Experienced team from Apple AIML and other great companies.
We're looking for a polyglot "startup engineer" at the Staff+ level can help with the end-to-end implementation of new features and capabilities and who can move between different components, be creative, be flexible, take ownership, and get things done. We have a complex, challenging product, but one that's amazing to work on and that will soon change how people think about working with each other and with AI.
You'll enjoy this role if:
- You like going 0 to 1 with high ownership: moving features and products from idea on a napkin, to prototype, to engineering UI, to shipped and polished product
- You are innovative, get satisfaction out of learning new things, and thrive in an environment of uncertainty and opportunity
To succeed, you should:
- Have the wisdom to know when to take the fast route vs when to step back and clean up your mess
- Be capable and excel on your own, but be humble and communicate well with others as projects require more collaboration
- Be versed across many programming languages (e.g. from C++/Java/Swift to Go to JavaScript or Python)
- Have worked on many types of projects and software -- have you built servers, written games, shipped native apps, and vibe-coded (kidding) web apps? If so, you're a fit.
- Be versatile and work both high level and low level, on old tech and new. Have you both prompt-engineered an LLM AND tweaked the code that decodes tokens in your own local LLM runner? If so, you're a fit.

* Safe tools that has processed $1B+ in seed funding in last 4 batches
* Fundraising CRM for founders manage their fundraise -- used by all founders
* Work at a Startup has 1M+ candidates on it, with 1000s of hires/year

Yet in reality, we're a team of 14 full-stack product engineers, the company is 85 people, and we intend to stay small and scrappy. I was the 7th engineer at salesforce and loved the early stage, and we get to be that way at YC... indefinitely.
YC is also knee-deep in applying AI tools and techniques across all of our product surface areas, and investor-focused work is no exception. We’re happy to share more when we chat in person.
We also want to work with people who love building full stack web apps. While our stack is Rails, React and Postgres, mostly we’re just a bunch of pragmatic builders who are excited about shipping and having impact.
