About Us

Conversion is the AI-native marketing automation platform for modern software companies. Our platform lets growth teams run their entire go-to-market motion in one place, from acquisition through retention, with AI agents doing the work that legacy tools like Marketo, HubSpot, and Pardot can't.

We've raised $28M+ from Abstract Ventures, True Ventures, and HOF Capital. The team is based in San Francisco and includes engineers, designers, and operators from Airbnb, Palantir, Pinterest, IMC, Shopify, LinkedIn, and Microsoft.

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 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 terabytes 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.

Here's what we're looking for in an infrastructure engineer to join our core team:

Engineer multiplier: Your customers are our product engineers. The goal is to unlock and empower them to ship features faster and more reliably for our customers. The best infra work here is measured in how much leverage you give the rest of the team.
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 it. Your job is to strike the line between the cost of infrastructure changes and the potential benefits. Everything's a tradeoff and we want to take the worthwhile ones.
Intellectually curious: Conversion engineers are the kind of people who get excited about a weird edge case and end up sending five Slack messages about it before lunch.

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

You Might Be a Good Fit If You

Have 4+ years of experience building cloud infrastructure, dev tooling, and platform systems at fast-growing companies
Have shipped and operated systems that other engineers depend on, including CI/CD, observability, deploy tooling, or internal platforms
Have a startup mindset and want early ownership in a fast-paced environment
Have experience with our tech stack:
- Go for backend services
- Kafka for large-scale data streaming
- Temporal for durable job execution
- PostgreSQL and ClickHouse as our databases
- GCP for cloud hosting

You Might Be a Great Fit If You

Have built internal developer tools or platforms that meaningfully changed how a team shipped
Have worked at a Series A to C startup that scaled quickly
Have a strong track record of side projects, apps, or hackathons. Our engineers have built a live-streaming security system for their parents' new house, a database from scratch, a better Splitwise app, and hosted our Minecraft server, all while at Conversion
