Growth Engineer
Job title: Growth Engineer
Location: London area (Hybrid)
Client: paid.ai
About the job
Paid is building the revenue engine behind the AI Agent economy, making it effortless for agentic startups to monetize, track costs, and scale with confidence.
As a Growth Engineer, you’ll join the team at a pivotal moment: right before we go fully public with our product, you’ll sit at the intersection of product, marketing, and engineering, helping us turn bold ideas into working growth experiments that bring in our next 100 customers.
About the Role
Our mission is to make it incredibly easy for AI startups to launch, price, and grow their business on top of Paid. That starts with the first click and ends with meaningful revenue.
As a Growth Engineer at Paid, you’ll own our website, analytics, and attribution, and build experiments that drive top-of-funnel growth. This means you won’t just be building landing pages, you’ll be testing hypotheses, measuring results, and helping define how we scale.
This is a rare opportunity to join an early-stage company where your work directly moves the metrics — from conversion to retention to expansion.
What You’ll Do
Own and evolve our main marketing site (Next.js, Tailwind, Vercel, Strapi).
Build out new high-converting landing pages, signup flows, and onboarding experiences.
Ship experiments: pricing selectors, waitlist incentives, AM/AMR calculators, referral loops.
Implement and maintain analytics (PostHog, GA4, HubSpot) and define clear attribution flows.
Help marketing and product measure what’s working — and kill what isn’t.
Create simple internal tools that become external growth loops (e.g. ROI calculators, embeddable widgets).
Collaborate with our founders, designers, and marketers to shape what we launch — not just how.
Skills & Experience You'll Need
3+ years of experience in a full-stack or frontend-focused role or design role.
Strong experience with modern frontend frameworks (we use Next.js, React, TypeScript).
Strong design capabilities - you’re comfortable in mostly Figma or Adobe Illustrator.
Comfortable spinning up backend endpoints (Node.js, serverless functions, Supabase, or Firebase, Strapi), with help from other engineers if necessary.
Familiar with tools like PostHog and Google Analytics for attribution.
Curious, fast-moving, and pragmatic: you know when to A/B test and when to just ship it.
Comfortable working independently with ownership and velocity, but also enjoy cross-functional collaboration.
Bonus: you’ve built or maintained a marketing site, worked on growth teams, or hacked together tools that got real traction.
Why This Role Is Special
You’ll own the growth surface which includes site, tools, tracking, and funnels
You’ll ship experiments with direct access to the founders
You’ll work at the heart of a fast-growing company defining a new category
You’ll turn your code into conversions, not Linear tickets
