About The Position

At Astra, we are builders. We want to be the gold standard for people in the Commercial Services trades. We are building a 100+ year business with an A+ team -- driven, excited about the future, and looking for people who want to build with us. We believe in hiring people with a growth mindset who are committed to building something bigger than themselves. Our culture is grounded in four core values: Coach, Compete, Collaborate, and Commit. We strive to be low ego, high performance, and deeply committed to our people, our Operating Companies, and our long-term vision. Astra Service Partners is a growing network of commercial services businesses across the United States, spanning HVAC, electrical, plumbing, building automation, and related trades. Our platform team is intentionally small -- about 40 people based in Colorado -- and we support a much larger network of Operating Companies and field employees across the country. Our Boulder office sees 5 to 8 platform team members on any given day, alongside a steady flow of remote colleagues coming in to collaborate, attend meetings, and participate in training. We run large, multi-day training and leadership events regularly, which makes the office an active and dynamic place. Astra is a roll-up-your-sleeves culture. At all levels, we expect people to prioritize, act quickly and effectively, demonstrate agility in their thinking, and get the job done every day. This is not a sit-back-and-direct environment -- we value doers, problem-solvers, and people who are hands-on and decisive. The Senior Executive Assistant & Office Manager is a critical operational role at Astra. This person ensures the executive team is supported seamlessly and that the HQ runs as a professional, welcoming, and well-functioning workplace every day. This is a role for someone who takes genuine pride in every detail -- who treats the office as their own, who notices what needs to be done before being asked, and who finds the work of supporting others intrinsically rewarding. We are looking for a seasoned professional who views executive assistance and office management as a craft and a career, not a stepping stone.

Requirements

Proactive and forward-thinking -- you scan your calendar and the office days and weeks ahead and act without being asked
Discretion, confidentiality, and values stewardship -- you sit at the center of the executive team and are trusted with sensitive information -- organizational, personnel, and strategic. You do not share, discuss, or speculate about confidential matters, and you do not engage in gossip of any kind. You actively model Astra’s core values in every interaction and understand that being a steward of the culture is as much a part of this role as any administrative function
Ownership mentality -- when something is not right, it becomes your problem to solve, even if you did not create it
Service orientation -- you derive genuine satisfaction from supporting others and take pride in their experience
Persistent and assertive -- you follow through until things get done. Booking a venue, confirming a vendor, or getting an answer from a third party may require multiple calls and follow-ups. You are comfortable pushing for a response and do not wait passively. Astra moves fast and this role must move with it
Resourceful and self-directed -- when you encounter an unfamiliar tool or task, you figure it out
High-volume triage and responsiveness -- you handle a high volume of requests across email, text, and in-person simultaneously. You have a system that works for you, you know what requires immediate attention versus what can wait, and you maintain responsive communication during business hours without being asked
Consistent and approachable -- you are warm, steady, and professional; people enjoy asking you for help
10+ years of experience in an executive assistant, office management, or executive operations role
Proficient in Microsoft Outlook on day one -- calendar management, scheduling, and inbox organization are core to this role. Comfortable across the full Microsoft Office suite including Excel, PowerPoint, Teams, and SharePoint, and brings strong file organization habits
