Administrative Assistant

Be the Force Multiplier Behind a Mission That Matters.

At Tellos, we’re on a mission to transform autism care by empowering BCBAs to run independent practices and giving families the fastest path to high-quality ABA therapy.
We’re a fast-growing, high-trust company with zero bureaucracy - and an A-player culture built on ownership, clarity, and care.

We’re looking for someone rare: an Administrative Assistant who operates like a mini Chief of Staff. Someone who frees leadership from the noise, organizes chaos into clarity, and keeps the business moving at the speed we need.

If you’re the type of person who hears “wear many hats” and your eyes light up - we want to talk to you.

What You’ll Own

1. Executive & Operational Support

• Act as a direct extension of the leadership team

• Remove friction from the day-to-day so leaders can focus on growth

• Own calendars, task management, follow-ups, and information flow

• Turn verbal ideas into structured action plans, docs, or workflows

2. Customer & Provider Support Oversight

• Monitor support channels and ensure fast, clear, human responses

• Identify recurring issues → propose and implement solutions

• Maintain internal SOPs and improve them as systems evolve

• Ensure nothing falls through the cracks for families or providers

3. Systems, Process & Documentation

• Create and maintain SOPs, checklists, templates, and knowledge bases

• Build repeatable processes across admin, intake, ops, HR, and support

• Spot inefficiencies and independently fix them

• Bring order, clarity, and standardization to fast-moving teams

4. Research, Projects & “Figure It Out” Work

• Handle one-off research (vendors, tools, regulations, best practices)

• Stand up small projects from 0→1 and hand them off once working

• Liaise with external partners, vendors, payers, and stakeholders

• Be the “I’ll take this and get it done” person on cross-functional gaps

5. Communication & Coordination

• Draft clear internal/external communications (emails, updates, docs)

• Manage follow-ups with leadership, clinical, operations, and recruiting

• Keep teams aligned when priorities shift

• Make sure information flows cleanly, quickly, and accurately

What You Need to Succeed

• 2–5 years in a fast-paced admin, ops, project coordinator, or chief-of-staff style role
  (Healthcare or startup experience is required.)

• Extreme ownership mindset - you don’t wait for instruction; you anticipate.

• Exceptional written communication — clear, concise, human.

• High attention to detail - you catch things others miss.

• Strong systems thinker - you can build order from chaos.

• Tech-savvy - CRMs, Google Workspace, AI and modern tools.

• High discretion & trustworthiness - you’ll handle sensitive information daily.

• Energy & speed - you move fast without sacrificing quality.

• Problem-solver DNA - “There’s always a way” is your default setting.
