When you apply through Sphere Rocket Jobs, you’re not applying for a job with us—we are not your employer or recruiter. Instead, you’re joining our talent pool so we can help connect you to remote opportunities submitted by U.S.-based business owners. These clients are looking for skilled Virtual Assistants, and we work to introduce talent that aligns with their needs. Sphere Rocket’s role is to guide, support, and introduce potential matches—but the hiring decision is always made by the client.

American influence depends on sea power and the industrial base to support it, a base that has become dangerously anemic. Valstad is building highly automated factories to produce ships for commercial & defense customers 5x faster and at globally competitive prices. We focus on 3 key areas: 1. Reinventing the shipbuilding process with modular designs & automated production lines. 2. Accelerating the shift to sustainable transport. 3. Achieving full autonomy to relieve critical labor shortages. Our first facility will manufacture ships that transport cargo via inland & coastal waters at a scale not seen since WWII.

Talent Scroll is a modern talent acquisition and recruitment company helping businesses find, attract, and hire the right talent faster. We connect ambitious companies with skilled professionals across a wide range of industries and experience levels. Our approach combines personalized recruitment, targeted talent sourcing, and a strong understanding of what both employers and candidates need to build successful, long-term careers. We solve one of the biggest challenges businesses face today: finding the right people at the right time. Instead of relying on a one-size-fits-all hiring process, we focus on understanding each company's requirements, culture, and goals before identifying candidates who are genuinely aligned with the opportunity.

We create companies from zero, grow the founders who run them, and compound every launch into venture intelligence. Six people in New York. Our founder was the founding design partner who helped build Partiful, Sentropy before Discord bought it, Goldcast before Cvent, and Make before Celonis. She builds here now instead of for other people. Everything sits on our own internal operating system and the products on top of it. We make reusable systems and tooling so the next build is faster than the last. React, TypeScript, Node, Cloudflare, and a lot of MCP servers. Build the ship as it sails. Perfection is the mastery of constant iteration and we thrive in organized chaos. Excellence always, because we have a reputation for the best and the best is just the starting point. Playful seriousness, serious playfulness: effervescent in the mornings, hungry in the afternoons, roguish at night. We make identity part of the craft. The front door is not the ceiling. People come in as a designer, engineer or operator and will grow into a Lead, a Partner, a Founder, or a Venture CEO. Design and engineering sit in the same room here, because bridging those two is the whole reason Sunspell exists. Looking for entrepreneurs, designers, engineers, dreamers, & if possible, a mix of them all. But at the end of the day, if you own your project and walk in and out each day with good vibes, you're going to be a great fit. :)
