About us:

Clocknext is building the Pricing & Billing Infrastructure for AI-Native Apps.

AI products are moving from simple API calls to autonomous agents, creating a completely new challenge around usage tracking, pricing, monetization, and billing.

We help AI-native companies understand what their agents are doing, measure usage and costs, define the right pricing metrics, and build scalable billing infrastructure.

About the role

Our growth motion is product-led and inbound-heavy. People find us through content and search, sign up self-serve, and start metering usage before they ever talk to a human. That only scales if the funnel behind it is instrumented and automated properly — and that's this role.

As our GTM Engineer, you'll sit between marketing, product and sales, and own the systems that connect them. Half marketing operations, half growth engineering: you'll design lifecycle automation, build enrichment and scoring pipelines, wire product signals into the CRM, and use AI to do work that would otherwise need three more people. This is a builder role, not a reporting role.

What you'll do

Own the GTM stack end to end — CRM, marketing automation, enrichment, product analytics — and keep data clean, connected and trustworthy across all of it
Build lifecycle automation across the self-serve journey: signup, activation, first metered event, credit top-up, upgrade, expansion, and win-back
Design product-qualified lead (PQL) scoring using real usage signals — SDK key generated, first billable event, credits consumed, seats added — and route high-intent accounts for follow-up automatically
Enrich and segment every inbound signup automatically (firmographics, tech stack, funding, AI-product signals) so outreach is relevant on the first touch
Build AI-assisted outreach and personalization systems grounded in real research and product behaviour — quality at volume, not spray-and-pray sequences
Instrument the funnel: UTM hygiene, attribution, conversion dashboards from visitor to signup to activation to revenue, and clear reporting on what's actually working
Run demand-gen operations: landing pages, forms, A/B tests, content and SEO distribution workflows, newsletter and webinar ops
Ship internal automations and AI agents that remove manual work from marketing and sales

What we're looking for

2–3 years in marketing operations, growth, RevOps or GTM engineering at a B2B SaaS company — product-led growth experience strongly preferred
Hands-on ownership of a CRM and a marketing automation platform (HubSpot)
Fluency with workflow automation tools — n8n, Zapier, Make, Clay or equivalent — and a track record of automating processes people used to do by hand
Working knowledge of APIs, webhooks and JSON; you can read documentation and connect two tools without waiting on an engineer. SQL and light scripting (Python or JavaScript) is a strong plus
Genuinely strong with AI: you use LLMs daily, write good prompts, and have built something real with them — an enrichment pipeline, a research agent, a content system. Using ChatGPT to write email copy isn't what we mean
Comfortable with product analytics (PostHog) and confident working with funnel data
Clear writer — GTM engineering is half systems and half copy
Bias to ship. You'll be early, with no inherited playbook and a lot of room to build
