About Rhythms

Rhythms is building the AI business execution system that enables enterprises to become AI-native-fundamentally rethinking how organizations operate, execute, and scale.

We're founded by entrepreneurs who built and sold Chronus (acquired by PE) and Ally.io (acquired by Microsoft). We've raised a $26M seed round from top investors including Green Oaks, Madrona, and Accel, alongside CXOs from global technology leaders-earning Geek Wire's 2024 Deal of the Year and named a 2025 AI Innovation of the Year finalist.

Rhythms transforms how enterprises become AI-native by connecting strategic planning and OKRs directly to day-to-day execution and real-time progress tracking. Built on multi-agent AI architecture, our platform connects with Slack, Teams, Jira, Linear, and other daily tools to automate operational workflows, surface predictive insights and risks, eliminate manual status updates, and build organizational memory that grows smarter over time. Enterprise customers choose us because we're making agentic AI reliable enough to run critical business operations.

The Role

We're hiring an Executive Assistant to work directly with our CEO and co-founder. You'll be the operational engine that keeps the CEO effective and the company running smoothly.

You'll own the CEO's calendar, communications, and operational rhythm while taking on strategic projects that directly impact the business-from hiring coordination to company operations to customer meeting prep. The best way to think about this role: you treat the CEO's time as the company's most valuable resource and you protect it accordingly.

This is a high-trust, high-autonomy role. You'll have visibility into every part of the business-product, strategy, customers, hiring-and you'll use that context to anticipate needs before they're asked.

What You'll Own

• CEO's time and calendar: Manage complex, high-stakes scheduling across investors, board members, customers, and the leadership team. Prioritize effectively-every meeting has context, an agenda, and clear outcomes.
• Company operations: Coordinate leadership offsites, all-hands, team events, and onboarding logistics for new hires. Help prepare materials for quarterly board meetings. Be the connective tissue across a distributed team (Seattle, SF, Hyderabad, Chennai).
• Hiring coordination: Partner with the People team to schedule interviews, manage candidate experience, and keep recruiting moving at startup speed.
• Communications: Draft emails, memos, and updates on behalf of the CEO-to customers, partners, and the team. You represent the CEO's voice with precision and professionalism.
• Strategic projects: Research, analyze, and execute on ad hoc priorities. This could range from vendor evaluation to event planning to competitive research to preparing customer meeting briefs.
• Travel and logistics: Plan domestic and international travel, process expenses, and handle logistics for conferences and customer visits.

Operator

• You don't wait for instructions-you see what needs to happen and do it

• Strong written and verbal communication-you'll draft executive emails, meeting briefs, and internal memos
• Detail-oriented: you sweat the small stuff because you know it matters
• You move at startup pace
