Platform Software Engineer

About Us

Conversion is building the AI-native marketing automation platform for modern software companies. Today, marketing is stitched together from outdated software, enrichment tools, and disconnected workflows. Funnels are broken. Messaging is misaligned. Most teams are flying blind.

We’re fixing that. Conversion lets growth teams build and automate their entire go-to-market motion in one place. From acquisition to activation to retention, it’s all managed in a single interface : fast, personalized, and powered by AI.

We’ve raised over $28 million from top firms such as Abstract Ventures, True Ventures, and HOF Capital. We’re at $5M+ ARR, growing quickly, and powering go-to-market for 4000+ customers.

We’re a lean, high-performing team in San Francisco. If you’re excited about building creative, modern, product-led marketing and doing your best work alongside world-class teammates; we’d love to meet you.

About the Role

Hey there! James here 👋, co‑founder and CTO at Conversion. Just wanted to share my thoughts on the perfect candidate we’re looking for to join our engineering team.

First off, I want to stress the technical difficulty and scale of what we’re building here at Conversion. The reason marketing automation platforms haven’t seen a new player in decades is because building one is hard. Our platform needs to handle gigabytes of data syncs per customer with the utmost reliability, coordinate complex workflows that automate mission critical "go‑to‑market" processes, handle form submissions that directly generate revenue for customers, and serve high delivering emails to millions of our customer’s recipients.

With that being said, here’s what we’re looking for in a platform software engineer to join our core team :

Engineer multiplier : You know how in Candy Crush you can hit a 2x multiplier? We believe it’s the same analogy for platform engineering : your customers are our product engineers, and the goal is to unlock and empower them to build features to serve our customers best.

Intellectually curious : Conversion engineers are a group of bright‑eyed and constantly curious individuals, who love debating database designs (or if we’d win in a fight against an ostrich) at lunchtime.

Pragmatic optimizer : Over‑optimizing is a real thing. As a startup, our goal is to grow and build an amazing product that delivers value, not to needlessly upgrade our tech stack for the sake of doing so. Your job is to strike the fine line between the cost of implementing infrastructural changes vs. the potential benefits. Everything’s a trade‑off, we want to take the worthwhile ones.

This role is in‑person 5 days / week in San Francisco .

You Might Be a Good Fit If You

Have experience building out cloud infrastructure, dev‑ops, and platform features at other fast‑growing companies

Have experience with our tech stack : Golang in the backend, a job queuing system with Kafka, PostgreSQL as our database and cloud hosting with GCP

You Might Be a Great Fit If You

Developer tooling fascinates you

Track record of side projects, apps, hackathons. Our engineers have built a live streaming security system for their parent's new house, a database from scratch, a better "Splitwise" app, and hosted our Minecraft server, all while at Conversion!
