Job description

GTM Engineer · Hybrid, San Francisco Bay Area

This role is for builders who have taken GTM from 0 to 1 at a startup. You've owned real execution, not just the tooling: you've created an entire GTM strategy, taken the initiative to launch it, and built the systems that made it work.

This is a hybrid role based in our San Francisco office. You should live in the San Francisco Bay Area and be able to work from the office a few days a week.

About a1mobile

a1mobile is building the AI-native carrier for businesses.

We're rebuilding the carrier layer, bringing mobile, landline, and AI phone systems together. Every business number should answer, understand, take action, and follow up.

Our first product, a1mobile One, is one business line for $99/month: unlimited calls and texts, 5G data, and an AI receptionist built into the carrier itself. It answers every call and text 24/7, takes bookings and orders, sends quotes and follows up. Our customers are small service businesses: restaurants, cafes, salons, studios, contractors, and hotels.

We recently raised an $11.5M seed round led by General Catalyst, with backing from Menlo Ventures, SV Angel, Commerce Ventures, and other leading investors.

We're looking for a GTM Engineer to build and run the systems that power our sales and marketing. You'll combine engineering skills with real go-to-market execution: shape the strategy, build the machine behind it, and own the results.

• Real 0-to-1 GTM execution at a startup: you've taken a product, market, or channel from zero to real traction, and can show the results.
• 2+ years in GTM engineering, revenue operations, growth engineering, or a technical sales or marketing operations role.

What you'll do

• Create and own entire GTM strategies: who we target, which channels we use, what we say, and how we measure it.
• Take the initiative: spot the next growth lever, build it, launch it, and share what worked, without waiting for a plan.
• Build automated prospecting and enrichment workflows to find and prioritize small businesses.
• Own our CRM setup, data model, and integrations.
• Create AI-powered workflows for outreach, lead scoring, routing, and follow-up.
• Build dashboards that show pipeline, conversion, and channel performance.
• Connect product usage data with our sales and marketing tools.
• Partner with Sales, Marketing, and Customer Success to remove manual work.

What we’re looking for

• A track record of real execution: you've built something from 0 to 1 at a startup, not just maintained a mature process.
• The ability to create a full GTM strategy and turn it into shipped campaigns, systems, and results.
• Strong initiative: you spot what needs to happen and make it happen without waiting to be told.
• Hands-on experience with tools like Clay, HubSpot or Salesforce, and Zapier, Make, or n8n.
• Experience using LLMs in real production workflows.
• Solid SQL skills and a habit of keeping data clean.
• A team player who communicates openly, shares knowledge, and collaborates closely with others.
• The flexibility to adapt and keep pace with a fast-moving startup.

Nice to have

• Experience as one of the first GTM hires at a startup.
• Experience with data warehouses or reverse ETL.
• Experience in telecom or with SMB go-to-market.

You'll build the go-to-market machine from scratch, with the freedom to set the strategy, use the newest AI tools, and the data to prove what works.
