Job Description

You will fix the bridge between sales and delivery by owning technical scoping, architecture, and quality assurance. As a hands-on leader, you'll join pre-sale calls to define feasibility, run technical discovery with mid-market clients, and enforce QA gates to ensure every build meets rigorous acceptance criteria before client delivery.

Location

Remote (US/Canada)

Why this role is remarkable

• True Architectural Authority: You own the full technical delivery loop and have the power to resize or decline work that cannot be delivered as sold.
• High-Impact Bootstrapped Agency: Join a lean, $2.3M revenue team building cutting-edge voice AI and automation for a massive $5M-$100M home services market.
• No Bureaucracy: Work directly with the Founder/CIO to build the delivery function from the ground up without corporate filler or management bloat.

What you will do

• Produce feasibility memos for $25k+ deals, identifying client stack inventory, open unknowns, and delivery hour ranges with high-confidence bands.
• Lead technical discovery sessions with client operations teams to create signed scoping documents featuring explicit out-of-scope lists and acceptance criteria.
• Own the data warehouse and security layer while reviewing offshore developer commits weekly to ensure architectural integrity across all active engagements.

The ideal candidate

• Proven background in agency, consulting, or professional services delivery with deep experience writing client-signed scoping documents and technical specifications.
• Hands-on technical depth in API integrations (QuickBooks, NetSuite, HubSpot) and data engineering using Postgres, warehousing, and orchestration tools like n8n.
• The backbone to tell a client "no" on feasibility and the communication skills to navigate working sessions with non-technical business owners.

First 90 Days:
In your first 90 days, you will establish the four core artifacts of our delivery engine: a standardized feasibility memo, a rigorous scoping document, an enforced QA gate process, and a formal change request reconciliation workflow.
