Job description

Base salary: $130,000–$160,000 · OTE: $175,000–$215,000

This is a remote role based in New York City. You should live in the New York City area. You'll spend much of your time meeting local businesses in person and work closely with our San Francisco team.

This role requires in-person, door-to-door sales. A large part of the job is visiting small businesses in person across NYC and getting them set up on an a1mobile business number.

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 Sales Engineer to be the technical partner for our New York sales team. You'll make a new kind of carrier easy to understand and easy to switch to: running demos, answering deep questions about numbers, porting, and AI call handling, and making sure every New York customer goes live smoothly.

• 3+ years as a Sales Engineer, Solutions Engineer, or Solutions Consultant in B2B SaaS, telecom, or VoIP.

What you'll do

• Run live demos that show the AI receptionist handling real calls, texts, bookings, and orders.
• Answer technical questions on number porting, eSIM and SIM activation, landline adapters, call flows, and integrations.
• Scope customer setups, from single-location shops to multi-location businesses, and design their call-handling workflows.
• Go door to door with our NYC sales team, visiting target businesses across New York City neighborhoods to demo the product live and sign them up on an a1mobile number.
• Partner with Sales Representatives and Account Executives through the full sales cycle, from discovery to technical close.
• Build demo environments, playbooks, and technical FAQs the whole sales team can use.
• Turn customer feedback into clear product input for engineering and product.

What we're looking for

• A solid understanding of telephony: phone numbers, porting, SIP/VoIP, call routing, and SMS.
• The ability to explain technical concepts in plain language to busy business owners.
• Comfort with APIs, webhooks, and SaaS integrations like calendars, POS, and booking tools.
• Excellent presentation skills, in person and on video.
• Comfort with door-to-door selling: walking into businesses, starting conversations with owners, and closing in person. Reliable transportation is needed.
• A strong sense of ownership and the ability to move work forward without waiting to be told.
• 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 with voice AI or LLM-based products.
• Experience at a carrier, MVNO, or UCaaS company.
• Knowledge of NYC neighborhoods and small business communities.
• Fluency in Spanish, Mandarin, or another language spoken by NYC business owners.
• Experience at an early-stage startup.

You'll sit at the intersection of telecom, voice AI, and sales, and help build our New York presence from the ground up. Your feedback will shape the product as much as the pipeline.
