Senior Executive Assistant, AstraSuperior, Colorado Position Description: Senior Executive Assistant & Office ManagerAstra Service Partners Our Culture At AstraAt 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 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.
