Job description

Starchild is building the interface for working with AI agents. Our product brings together chat, automation, tools, memory, workflows, and multimodal creation into one AI‑native workspace. We are exploring what happens when agents are not just assistants, but active collaborators that can help people research, build, monitor, create, and operate. We are looking for people who enjoy building from first principles, moving quickly, and turning messy, open‑ended problems into products that feel simple and useful.

About the opportunity

We are looking for an entrepreneurial Executive Assistant based in Florianópolis to work directly with the founder. You'll be the operational backbone of a fast‑moving AI startup — managing priorities, coordinating projects, and ensuring that ideas move from concept to execution with quality and speed. This is not a traditional EA role. You won't just manage calendars and inbox. You'll be a thought partner, project driver, and creative contributor who helps shape how things get done.

What you’ll be working on

• Manage the founder's schedule, communications, and priorities across multiple time zones and project areas.
• Coordinate and track projects from kickoff to delivery, ensuring deadlines and quality standards are met.
• Prepare briefings, decks, and visual materials — your design sense will directly shape how our work is presented internally and externally.
• Act as a liaison between the founder and internal teams, external partners, and stakeholders.
• Help research, organize, and synthesize information to support fast decision-making.
• Take ownership of ad‑hoc initiatives — from planning an offsite to sourcing a vendor to drafting a proposal.

Who will you be working with

• The founder — daily, as your primary partner.
• All internal teams: engineering, product, operations, and people.
• External partners, vendors, and stakeholders across multiple countries and time zones.
• A multilingual environment — Spanish, Portuguese, and English in regular use.

What challenges will you face

• Priorities shift fast and structure is often minimal — you'll need to decide what matters, not just what's next.
• Absorbing context quickly and triaging intelligently to protect the founder's time without becoming a bottleneck.
• Holding ambiguity and making judgment calls with incomplete information.
• Switching between wildly different types of work — from project roadmaps to sourcing a vendor in a country you've never worked in.
• Maintaining quality and consistency across all of it.

About you

• Fluent in Spanish, Portuguese, and English (all three required).
• Entrepreneurial mindset — you take ownership, move fast, and figure things out with limited structure.
• Strong aesthetic taste and design sensibility — you care about how things look and feel.
• Project management experience or background.
• Proactive, resourceful, and comfortable with ambiguity and evolving priorities.

Bonus

• Experience in a startup or high‑growth environment.
• Background in design, architecture, or related creative fields.
• Familiarity with AI tools and no‑code platforms.

Additional Info

• Full‑time, based in Florianópolis.
• Compensation commensurate with experience.

We are an equal opportunity employer. We welcome applicants from all backgrounds and are committed to building a respectful, inclusive hiring process.
