MailerCloud is a UK-headquartered, high-volume email marketing platform processing over 1 billion emails per month for businesses across the globe. Our engineering team builds and maintains the full stack â from customer-facing campaign tools to the bare-metal sending infrastructure â on a modern tech stack of Go microservices, PHP (legacy), Vue 3, ClickHouse analytics, MySQL, RabbitMQ, and Rocky Linux 9 on dedicated bare-metal servers.
We are a lean, high-impact team. Every engineer owns meaningful parts of the product, collaborates directly with leadership, and sees the results of their work at massive scale.
We are looking for a versatile Software Engineer with 3 â 4 years of hands-on experience to join our engineering team. This role is central to our product evolution: you will be a full participant in building, shipping, and scaling features across MailerCloud's entire stack â from RESTful APIs and backend services, to frontend components, developer tooling, and CI/CD pipelines.
You will work closely with the lead developer and the Product Manager, owning features end-to-end, contributing to our AI agent infrastructure (MCP-first architecture with Claude), and helping maintain the reliability of a platform that sends billions of emails.
