About SentSent 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 RoleWe'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 DoRun live product demos and technical deep-dives for developer and product audiencesBuild proof-of-concept integrations during or between prospect calls - you're comfortable spinning up a working example to unblock a dealTranslate 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 fasterWrite technical content that supports the deal cycle: solution briefs, architecture diagrams, competitive comparisons, integration playbooksPartner with engineering and product to relay what you're hearing from prospects - feature gaps, DX friction, competitive intelSupport RFP/RFI responses and security questionnaires as they come upHelp define the SE function from scratch: build the playbook, tooling, and processes that will scale as we grow What We're Looking For5+ 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 itComfort working with APIs, webhooks, and at least one language (Python, Node.js, etc.) — you can read docs and build a working integration without hand-holdingA 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-handsHigh 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 managedStrong written and verbal communication: you can write a technical doc as easily as you can walk a prospect through an architecture decisionGenuine curiosity about how messaging infrastructure worksA bias toward action and learning: you'd rather ship something imperfect and iterate than wait for perfect informationLives in NYC or willing to relocate Nice to HaveContributions 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 YouMeaningful equity with high growth potentialTop-tier medical, dental, vision fully covered401(k) with 100% match up to 4%Unlimited PTOBeautiful NYC workspace with daily meals and unlimited snacksNew MacBook Pro + Apple Studio DisplayWellhub Gold or Equinox stipend Sent, Inc. is an Equal Opportunity Employer committed to building a diverse and inclusive team.
