WHY THIS ROLE EXISTS

You'll be the first engineer dedicated to owning those critical paths:
onboarding, activation flows, monetisation infrastructure, and the
experimentation systems that help us improve all of it. As JustCall expands how
it serves customers - from individual sales reps to small teams to mid-market
organisations running AI-powered call workflows - you'll play a central role in
building the growth engine that scales with them.

We're looking for a Senior Full-Stack Growth Engineer who is excited to build
those journeys end-to-end. You'll work at the intersection of engineering,
product, and data to create rapid, reliable growth systems that turn first-time
users into activated users, and activated users into expanding accounts.

WHAT YOU'LL ACTUALLY DO
Own and improve key product journeys from sign-up through onboarding, feature
discovery, and purchase
Build and refine onboarding experiences that help users - individual reps,
team admins, growing accounts - quickly understand and realise the value of
JustCall




Design and implement self-serve billing flows: subscriptions, plan gating,
trial logic, seat expansion, and upgrade paths that work without a
salesperson
Wire AI into the growth experience: personalised onboarding, intelligent
nudges, value demonstrations - built to production standard
Iterate quickly, delivering thoughtful, incremental improvements that
compound over time
Contribute to the evolution of our onboarding and discovery systems as the
product and customer base continue to grow.
Integrate third-party and AI tools that enrich the product experience.

WHAT WE'RE LOOKING FOR
5+ years of full-stack engineering experience, with meaningful time on
growth, self-serve, or PLG systems
Frontend depth - solid JavaScript, HTML, CSS. You care about what users
experience, not just whether the backend call succeeded
Robust Next.js fluency - you understand SSR, CSR, and ISR and choose
deliberately, not by default
