Sift Stack, Inc.•El Segundo, CA

5d•$75,000 - $107,000•Hybrid

About The Position

We're looking for a sharp, proactive, and deeply organized Executive Assistant to support our CEO and CTO. This isn't a traditional EA role. It's a high-leverage operational position at the center of a fast-moving, mission-driven startup. You'll own the time and logistics of two founders, help drive outcomes across the company, and take on research and special projects that have real business impact. If you're the kind of person who notices what needs to happen before anyone asks and makes it so, this role is for you.

Requirements

2+ years of experience as an Executive Assistant or in a similar operational support role, ideally at a startup
Experience supporting multiple C-suite executives simultaneously
Exceptional organizational skills: you don't miss things, and you have systems to make sure of it
Strong written and verbal communication; comfortable corresponding with investors, customers, and partners on behalf of executives
Highly proficient in G Suite (Gmail, Calendar, Docs, Sheets) and Slack
Proactive and assertive: you anticipate, you follow up, and you get things done
Discreet and trustworthy with sensitive and confidential information
US Person Required: Must be a U.S. Citizen or Green Card Holder due to ITAR (International Traffic in Arms Regulations) / EAR (Export Administration Regulations) compliance requirements.

Nice To Haves

Experience at an aerospace, defense, deep tech, or engineering-heavy company
Familiarity with Notion, Ramp, or similar tools
Experience with investor relations, board logistics, or customer-facing event coordination
Comfort in ambiguous, fast-moving startup environments where the job evolves quickly
Interest in the future of hardware, autonomy, space, or defense technology

Responsibilities

Own and proactively manage complex, dynamic calendars for the CEO and CTO: scheduling, resolving conflicts, and protecting time for deep work
Coordinate all domestic and international travel: flights, accommodations, ground transport, and detailed itineraries
Serve as the communication hub between the CEO, CTO, and the broader team: tracking action items, driving follow-through, and ensuring nothing slips
Conduct research to inform executive decisions: vendors, markets, customers, events, and more
Prepare meeting agendas, briefing materials, and follow-up summaries
Manage vendor relationships, office operations, and ad hoc logistics (swag, catering, facilities, events)
Support investor relations, customer visit coordination, and external-facing events
Take on special projects that improve how Sift operates: no task is too big or too small
