Growth & Marketing 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 $5.1M Seed round backed by Companyon Ventures, Bessemer Venture Partners, UIF, and CEAS Investments. We're hiring to build the best infrastructure to replace multi-channel messaging stacks.
About the Role
We're hiring someone to take over and scale our growth engine - programmatic SEO, paid acquisition, conversion optimization, and the full product-led growth funnel. This system is already generating pipeline. Your job is to own it, improve it, and scale it so our CEO doesn't have to run it anymore.
You'll own everything from top-of-funnel acquisition to signup-to-activation conversion. That means managing paid campaigns, scaling the SEO and content engine, running experiments on landing pages and onboarding flows, building lifecycle email sequences, and obsessing over the data that tells you what's working and what isn't. You'll work closely with engineering, sales, and product to turn developer traffic into paying customers.
This isn't a brand marketing role and it isn't a management role. You'll be in the weeds every day shipping experiments, such as: launching programmatic content, building demand generation systems, automating lead qualification, etc. Ideal for someone highly technical who's early in their career but already knows how to run growth systems end to end.
What You'll Do
Acquisition & SEO
Take ownership of Sent's existing programmatic SEO and paid acquisition engine
Optimize and scale paid channels with tight CAC and ROAS targets
Maintain and expand the content and SEO strategy that currently drives organic pipeline
Build and test landing pages, CTAs, and conversion flows continuously
Product-Led Growth
Own the self-serve signup funnel from first touch to activated paying customer
Analyze signup-to-activation funnels, identify drop-off points, and ship fixes
Build automated onboarding, nurture, and re-engagement email sequences
Work with product and engineering to improve in-product conversion and activation triggers
Analytics & Experimentation
Run A/B tests across landing pages, email, ad creative, and onboarding flows
Build and maintain growth dashboards covering the full funnel — traffic, signups, activation, revenue
Report on CAC, ROAS, channel efficiency, and cohort-level activation metrics
Use data to prioritize experiments and allocate budget
Cross-Functional
Collaborate with GTM on product-led growth initiatives and technical content
Work with sales on lead scoring, MQL definitions, and handoff optimization
Partner with marketing on developer-focused campaigns, community, and content distribution
What You'll Bring
Required
0–2 years in growth marketing, demand generation, or engineering at a startup
Highly technical - comfortable with code, data, and building things yourself
Proficiency with marketing automation and email tools
Strong analytical skills - comfortable with SQL, Google Analytics, or BI tools
Experience running A/B tests and optimizing conversion funnels
Data-driven decision-making with a bias toward experimentation
In NYC or willing to relocate
Nice to Have
Experience marketing developer tools, APIs, or technical products
Familiarity with product-led growth motions and self-serve funnels
Front-end skills (HTML/CSS, React, landing page builders) for rapid experimentation
Experience with programmatic SEO or content-driven organic growth at scale
Experience with Clay, Clearbit, or similar enrichment tools for targeted outbound
What Makes This Role Special
Inherit a Working Engine: You're not starting from zero - you're taking over a growth system that's already generating pipeline and making it better.
Full-Stack Ownership: Own the entire funnel from awareness to activation to expansion. No siloed channel ownership, no waiting for approvals.
Developer Audience: Market to people who hate being marketed to - substance wins, gimmicks fail.
Direct Revenue Impact: Your work directly drives signups, activation, and revenue. You'll see the numbers move.
