Founding AI Systems Engineer (USA Only - 100% Remote)

Close is a bootstrapped and profitable CRM company that has been helping SMBs succeed since 2013. They are seeking a Founding AI Systems Engineer to rebuild their internal systems around AI, taking ownership of building AI-powered tools and automation to enhance their operations.

Responsibilities:

• Build AI-powered internal tools from scratch. Lead scoring models. Slack bots that answer business questions against live data. Agents that generate business reviews and surface insights without a human analyst pulling the report. Things we haven’t even thought of yet
• Ship automation that actually gets used. Sales and Marketing have workflows that are far slower than they should be. You’ll find the bottlenecks, scope the fix, and build it
• Work across our GTM stack (Segment, Customer.io, Close, the data warehouse) You’ll make connections clean and well-documented as you build on top of them
• Build experimentation and growth infrastructure so the team can run tests, measure impact, and scale acquisition without engineering bottlenecks
• Define what this function looks like at Close - there’s no playbook. You’ll figure out where engineering leverage is highest and turn that into a roadmap nobody handed you

Requirements:

• Located in the US (ET, CT, MT, PT)
• A builder who moves fast and thinks in systems
• Technically full-stack. Python backend, TypeScript or JS frontend
• You've used AI tools enough to have opinions and know what it takes to use AI to compound your leverage
• You're comfortable picking up new infrastructure and data tools when the problem calls for it
• Someone who gets how businesses run
• You understand what GTM teams are trying to do, why lead scoring matters, what good attribution looks like
• Able to build trust fast
• You'll work across the whole org - Marketing, Sales, Engineering, Leadership
• Low ego and genuine curiosity are how things get done at Close
• Build AI-powered internal tools from scratch
• Ship automation that actually gets used
• Work across our GTM stack (Segment, Customer.io, Close, the data warehouse)
• Build experimentation and growth infrastructure
• Define what this function looks like at Close
