Pareto.AI | Multiple Roles | INTL REMOTE, US REMOTE OR HYBRID (SF) | https://pareto.ai

Pareto.AI is in the premium data annotation space, focused on ethical, high-quality data annotation. We work with almost all of the frontier labs. We are a fully distributed, remote-first company with engineering teams spread around the world. Some of us work hybrid from our office in SF. There is essentially no restriction on where you're located as long as you're not from a sanctioned country and are willing to adjust to either a US or EMEA timezone.

We have a few full-time, fully-remote roles available. For those two below, we've recently restructured how we do engineering at Pareto and are looking to be very talent dense. I've hired successfully from HN multiple times in the past, so if you have expertise in those respective tech stacks I'd love to chat:

* Lead/Senior+ Backend Eng: https://jobs.ashbyhq.com/pareto-ai/569f4da0-801c-433a-978f-5...

* Lead/Senior+ Frontend Eng: https://jobs.ashbyhq.com/pareto-ai/47552c42-82c1-4bcd-a1f7-e...

We're also looking to hire some shorter term contractors. We have a couple of projects around refactoring and migrating to a new design system, as well as some shorter term projects around compliance, so if you're only available for a short time we'd likely have room for you too:

* Short term/Contract -> Mid-Staff level Front/Backend/Full stack Eng: https://pareto.ai/careers?ashby_jid=4cbdb231-c7c5-40cd-ad9d-...

Backend code-writing roles require a really strong command of Python. Equally for the frontend roles you really need to understand your TypeScript and React. You're expected to have a lot of responsibility.

No recruiting agencies or similar.

You can reach me directly at steven@[domain] if you have any questions that aren't covered by this post or the job listings, but any applications would need to go directly through the link above. After you have applied, feel free to drop me a one-liner email with the subject "Via HN: Applied" letting me know so I can make sure you don't get caught up in the screening flow.

Leadership Development – Strategic Partnership (Remote)

Are you an established consultant or a retired executive with a network you're not ready to stop using?

This isn't a job; it's a strategic partnership. We are Relationship Media, LLC, a leadership education company founded by a 20-year law enforcement veteran and former S.W.A.T. commander. We have a proven, "sticky" training program that solves the single biggest problem in organizations today: The Relationship Gap.

We’re not selling abstract theory. We sell a practical, example-driven blueprint for leadership (using our proprietary "Be Like Tony & Don't Be Like Chad" framework) that helps organizations in public service, manufacturing, and healthcare solve their $223 billion crisis of cultural disconnection.

We have the product. We're looking for partners who have the relationships.

The Opportunity: Two Ways to Earn We are recruiting a small team of commission-based partners to bring this vital training to their networks.

1. The Certified Partner (White-Label): This is for independent consultants, coaches, and trainers. We will white-label our entire online course with your brand, logo, and welcome video. It becomes your product. You sell it to your clients and keep a significant portion of the revenue. Stop trading your time for money and add a scalable, recurring income stream to your practice.

2. The Affiliate Partner (Referral-Based): This is for retired executives and well-connected professionals. You make high-level introductions to your network (City Managers, Police/Fire Chiefs, Plant Managers, HR VPs). When we close a deal for in-person or online training, you earn a generous referral commission. You leverage your credibility; we do the rest.

Who We Are Looking For: • Profile 1: The Independent Consultant. You are an HR, OD, or leadership consultant, etc., looking for a proven, high-quality curriculum to sell to your existing clients. • Profile 2: The "Encore Career" Executive. You are a retired/semi-retired leader (e.g., City Manager, Police/Fire Chief, HR Director, Operations VP, etc.) who wants to leverage your network for a flexible, lucrative, and meaningful opportunity.

This is a 100% commission-based partnership for established professionals who understand that their relationships are their most valuable asset.

If you are a high-level connector ready to monetize your network by solving a real-world problem, we want to talk to you.
