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 Sent, Inc. is an Equal Opportunity Employer committed to building a diverse and inclusive team.
