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.

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

• Fully comped Wellhub Gold or Equinox membership
