Sales Engineer
Phonely, Inc., San Francisco, CA, United States
Sales Engineer
At some point in the future, every business will answer their phone with voice AI. We are building the platform that makes it possible. Phonely builds conversational voice AI agents for high-volume phone workflows. Our customers use us to qualify leads, book appointments, route calls, and resolve real customer conversations in production. We're growing fast and our deals are getting more technical. We need someone who can bridge the gap between what we sell and how it actually works.
About the Role We're hiring a Sales Engineer to partner with our sales team on technical discovery, demos, and proof‑of‑concepts for prospective customers. You'll be the person in the room who can answer the hard questions, build out a demo that maps to the customer’s actual call workflows, and make the technology click for technical and non‑technical buyers alike.
This role sits at the intersection of sales and engineering. You’ll be on calls with prospects to understand their telephony setup, integration requirements, and compliance constraints, then work with our team to scope a solution that wins the deal. You’ll also build demo environments, run technical evaluations, and support POCs through to production.
If you like solving puzzles, talking to customers, and making complex technology feel simple, this is your role. There’s a natural overlap with our CS and Forward Deployed Engineering teams, so if you could land in any of those seats, even better.
What You’ll Do
Partner with AEs on technical discovery: understand the prospect’s call flows, integrations, data requirements, and compliance needs
Build and deliver tailored product demos that map to each customer’s specific use case
Scope and manage proof‑of‑concepts from setup through evaluation
Answer technical questions on APIs, webhooks, telephony (SIP, Twilio), integrations, and security
Translate customer requirements into implementation plans for engineering and CS
Create technical documentation, architecture diagrams, and RFP responses
Support procurement and security reviews during the sales process
Provide feedback to product and engineering on feature gaps and customer needs
Build reusable demo environments and technical sales collateral
Stay current on the voice AI landscape and competitive technology
What You’ll Bring
3+ years in sales engineering, solutions engineering, or a technical pre‑sales role
Strong understanding of APIs, webhooks, cloud infrastructure, and SaaS integrations
Ability to demo complex products and make them feel simple
Excellent communication skills, both with technical teams and business stakeholders
Comfortable working in a fast‑paced environment with multiple deals in flight
Experience in telecom, voice, contact center technology, or SaaS is strongly preferred
Hands‑on, you’re comfortable building things, not just talking about them
Nice to Have
Experience with telephony (SIP, Twilio, Five9, Genesys)
Familiarity with LLMs, voice AI, or conversational AI platforms
Background in customer success or forward‑deployed engineering
Programming experience (Python, JavaScript, or similar)
Why Join Phonely We are a team of ex‑athletes, founders, and builders with low egos and high standards. We take the work seriously without taking ourselves too seriously. On‑site in San Francisco, meals covered, quarterly off‑sites to interesting places (Rocky Mountains, Costa Rica, Indonesia), and meaningful equity in a company that is growing fast. You will work directly with the sales team and founders and have real ownership over how we win technical deals.
Interview Process
15‑min intro call to evaluate fit
Technical deep dive with a team member
Mock demo: present Phonely to a simulated enterprise prospect
Final conversation with leadership
