About the role

About CreativeX

CreativeX is building the system of creative control for an AI-first marketing world. As AI changes how content is made, evaluated and distributed, the world's biggest brands need a trusted way to bring consistency, intelligence and governance to their creative at scale.

For more than a decade, we've helped brands including Google, PepsiCo, Heineken and P&G power every creative decision with data. Our platform combines machine learning with expert human review to turn ad creative into structured data, so marketers can see what works, prove its impact on sales and brand, and improve it across markets and platforms.

About the Role

Every CreativeX product runs on infrastructure our Platform Engineering team owns, from ingesting ad creative at scale to serving the creative scoring our customers rely on. As a Senior Software Engineer on that team, you'll own the reliability, performance and scalability of our production infrastructure. That means designing, operating and evolving the systems themselves, not only running code on top of them.

We're investing in our core architecture: evolving our data layer, scaling the infrastructure that runs our processing pipelines and automating more of how we operate. You'll lead the database migrations and rearchitecture work that make this possible, and build the tooling that lets other engineers deploy, test and debug on their own. You'll write production code, but most of your impact will come from how our systems are designed, run, observed and scaled.

We're looking for a change agent. You challenge the status quo, you look at a system that works and want to make it faster, more reliable and easier to run, and you bring other teams along with you. This is an opportunity to shape the platform that CreativeX's next stage of growth is built on.

You'll be responsible for the reliability and performance of our production systems, database migrations and rearchitecture, the scaling and observability of our infrastructure, and the self-service tooling our engineers use every day.

What you'll do

- Reliability and incident response

- Own, and be the go-to expert for, the reliability and performance of our production systems

- Set and meet reliability and performance targets for the platform

- Respond to production incidents and lead post-incident reviews that result in lasting fixes. We don't have a formal on-call rotation yet (it's coming), so we expect flexibility when incidents happen

- Database migrations and rearchitecture

- Lead database migrations and rearchitecture projects across teams, from planning and risk assessment through cutover and rollback, with minimal disruption to customers

- Infrastructure scaling and observability

- Scale the infrastructure that runs our data processing pipelines, keeping it reliable and performant as data volumes and throughput grow

- Improve observability, monitoring and alerting across our systems, using AI-assisted workflows to cut manual investigation and repetitive operational work
