Product development engineer Jobs in Pasadena, CA

The Role

ClickFlow is hiring a Full Stack Engineer (Product Builder) to own revenue-impacting product systems from idea to production.

This is not a ticket executor role.
This is a revenue-impact product builder mandate.

ClickFlow is at an inflection point where product must directly drive growth. We need someone who thinks like a product owner - someone who has built and shipped products independently, brought them to market, and iterated based on real user feedback.

This role exists to:

• Increase Free Trial → Paid conversion

• Drive product-led expansion revenue

• Accelerate engineering velocity through AI-native workflows

• Build measurable ARR growth systems

You will operate like a founder-level builder inside a startup, with full ownership across frontend, backend, and production environments.

If you are looking for detailed specs and assigned tickets, this is not the role.
If you want to own revenue levers and ship at elite velocity, read on.

We practice what we preach: our podcast has 150+ million downloads, and more than 193,000 marketers subscribe to our YouTube channel.

We move quickly, push hard, and expect a lot from ourselves and each other. AI isn’t just a tool we use, it’s core to how we operate, from creative to strategy to execution. Our long-term vision is to build a small but elite team that stays lean, scrappy, and relentlessly focused on tech-enabled innovation and measurable business impact.

We don’t micromanage. We don’t hire people who need their hands held. But we do collaborate deeply, give honest feedback, and leave space for mistakes, growth, and iteration. No egos, no fluff, just people who care about doing great work and supporting each other.

What You’ll Do

• Build and ship production code from Day 1

• Own features end-to-end: idea → code → production → iteration

• Improve Free Trial → Paid conversion through product experimentation

• Build in-product upsell and expansion triggers

• Design and run activation experiments

• Instrument analytics and event tracking to measure user behavior

• Improve funnel performance, activation rates, and LTV

• Maintain product reliability and performance while shipping fast

• Implement AI-native engineering workflows to multiply velocity

• Make product tradeoff decisions independently

Non-Negotiable Requirements

• Put “AI is cool” as the first line of your cover letter or subject line, or your application will not be reviewed.

• Has built and shipped a product independently

• Comfortable owning full-stack development (frontend + backend)

• Strong production environment experience

• Demonstrated AI-native engineering workflows

• Comfortable making product tradeoff decisions

• Thinks in funnels, activation, retention, and LTV

• AI experience is mandatory.

You must demonstrate real depth in using tools like ChatGPT, Claude, Cursor, or similar - not just prompting for snippets, but accelerating architecture, debugging, experimentation, and shipping velocity.

If you use AI casually but do not rely on it as a force multiplier, this role is not a fit.

Ideal Profile

You are:

• A product builder, not a feature implementer

• Comfortable operating with high autonomy

• Biased toward shipping

• Analytical about growth and conversion

• Founder-minded in ownership and decision-making

• Comfortable in early-stage startup environments

• Experienced in PLG (Product-Led Growth) systems

• Familiar with A/B testing and experimentation frameworks

What This Role Is NOT

• Not a junior engineer scaling up

• Not a pure backend specialist

• Not someone who waits for detailed product specs

• Not someone who “just builds tickets”

We want a product builder who thinks independently and prioritizes impact.

Interview Process

We will evaluate candidates on:

• What they’ve personally built and shipped

• Evidence of product thinking

• AI usage depth (must go beyond surface-level use)

• Ability to prioritize revenue-impact work

• Ownership mentality

Finalists will complete a working session designing a 90-day plan to improve product conversion.
