Job description

Role

SellScale is building the first Agentic Sales Org, starting with Selix – an AI agent for outbound sales. Think of it as a virtual teammate that lives in your Slack, Salesforce, LinkedIn, and email – then works as your sales companion to get top‑of‑funnel leads. We’re hiring a Founding Business Operations to work directly with the founding team. You’ll be at the center of how SellScale runs—owning projects across go‑to‑market, internal operations, customer success, and product. If you’re looking for a place to future‑prove your career, this is it. You’ll be knee‑deep in AI Agents, learning about the latest from OpenAI, Anthropic, LLMs, and the future of work. The engineering‑to‑operations ratio at SellScale is 3:1, providing an unheard‑of learning experience for non‑technical folks. All this will happen not as an “associate”, but as an owner, where you will be owning and building key parts of the company.

Requirements

• Willing and able to work 5 days a week in–person at our San Francisco office minimum
• Prior experience in operations, consulting, banking, PE, sales, or a fast‑paced startup environment (2 years of work experience required)
• Self‑starter who can own projects end‑to‑end without step‑by‑step guidance
• Comfortable with long hours, steep learning curves, and wearing multiple hats
• Strong interest in agentic AI, outbound sales, or startup operations
• Familiarity with tools like Notion, Excalidraw, and Zapier is a plus
• Prior SQL or coding experience is an added premium

Skills

• Excellent communication and writing skills (you may interface with customers or partners)
• Knack for sales – you need to either quickly learn how to onboard onto sales (specifically outreach) or have done it before
• Can run through walls – there will be a lot of tough challenges, so we need someone who can do whatever is needed to get the job done, even if it isn’t scalable
• Analytical mindset: comfortable with metrics, dashboards, and operational KPIs. You may be managing customer KPIs and your own
• Can work cross‑functionally across customer success, product, growth, and operations – this role is not only product or only customer success
• Bias for action – you prefer to move fast and improve later

Reasons it may NOT be a fit

• You want a clearly defined ops playbook – this role requires figuring things out from scratch.
• You prefer remote or hybrid work – we work 5 days a week in‑person in San Francisco.
• You’re looking for a large‑company environment – this is an early‑stage startup where everyone wears multiple hats.

Positives

• You’ll get exposure to a wide range of business problems—from customer success to go‑to‑market to internal ops—and own real projects end‑to‑end.
• You’ll work closely with the founders and core team, with direct input on how the company operates and grows.
• You’ll learn what it actually takes to build and scale an early‑stage startup, especially one at the forefront of agentic AI and modern outbound sales.
