Sales Engineer
About Sent
Sent is an infrastructure for sending A2P messages across SMS, WhatsApp, and RCS through a single unified API. Our intelligent routing model automates channel selection based on deliverability and cost, ensuring lower cost and global reach without any channel-specific integrations.
We recently closed a $12M Series A backed by Companyon Ventures, Bessemer Venture Partners, UIF, and others. We're hiring to build the best infrastructure to replace multi-channel messaging stacks.
About the Role
We're looking for our first Sales Engineer - someone who comes from the messaging or communications infrastructure industry and has an engineering or CS background but lights up in conversations with people. You might be a software engineer who keeps getting pulled into customer calls, a solutions engineer ready for something more entrepreneurial, or a technical support engineer who's ready for something more strategic. Whatever the path, you're someone who genuinely enjoys translating how things work into why they matter.
This is a ground-floor hire. You'll work directly alongside our VP of Sales to run the technical side of every deal - demos, proof-of-concept builds, integration architecture, and objection handling. You'll shape how technical buyers experience Sent for the first time.
What You'll Do
Run live product demos and technical deep-dives for developer and product audiences
Build proof-of-concept integrations during or between prospect calls - you're comfortable spinning up a working example to unblock a deal
Translate Sent's API capabilities into concrete solutions for prospect-specific messaging workflows (transactional SMS, WhatsApp conversational flows, OTP delivery, marketing campaigns)
Create and maintain demo environments, sample apps, and integration guides that make the sales cycle faster
Write technical content that supports the deal cycle: solution briefs, architecture diagrams, competitive comparisons, integration playbooks
Partner with engineering and product to relay what you're hearing from prospects - feature gaps, DX friction, competitive intel
Support RFP/RFI responses and security questionnaires as they come up
Help define the SE function from scratch: build the playbook, tooling, and processes that will scale as we grow
What We're Looking For
5+ years of experience, with a foundation in software engineering, computer science, or a related technical field - you've written real code, not just talked about it
Comfort working with APIs, webhooks, and at least one language (Python, Node.js, etc.) - you can read docs and build a working integration without hand-holding
A natural pull toward people: you're the engineer who volunteers for the customer call, writes the clearest Slack explanation, or ends up demoing at the all-hands
High agency: you don't wait for a playbook to exist before you start moving. You figure things out, ask good questions, and close loops without being managed
Strong written and verbal communication: you can write a technical doc as easily as you can walk a prospect through an architecture decision
Genuine curiosity about how messaging infrastructure works
A bias toward action and learning: you'd rather ship something imperfect and iterate than wait for perfect information
Lives in NYC or willing to relocate
Nice to Have
Contributions to open-source projects, developer communities, or technical content (blogs, tutorials, videos)
Experience in customer-facing technical roles: support engineering, developer advocacy, technical consulting, or solutions architecture
Our Commitment to You
Meaningful equity with high growth potential
Top-tier medical, dental, vision fully covered
401(k) with 100% match up to 4%
Unlimited PTO
Beautiful NYC workspace with daily meals and unlimited snacks
New MacBook Pro + Apple Studio Display
Wellhub Gold or Equinox stipend
