About Mailercloud

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 — from customer-facing campaign tools to the bare-metal sending infrastructure — 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.

Role Overview

We are looking for a versatile Software Engineer with 3 – 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 — 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.

Key Responsibilities

Product Development

Design, build, and ship backend APIs and microservices in Go and PHP for MailerCloud's campaign, automation, and analytics modules

Develop and maintain Vue 3 frontend components and SPAs, working from Figma designs to pixel‑perfect, performant UIs

Contribute to integrations with e‑commerce, CRM, and other platforms where email is a major communication channel (GraphQL APIs, webhook pipelines, data sync)

Infrastructure & DevOps

Work with dedicated bare‑metal servers (Rocky Linux 9) for deployment, configuration, and troubleshooting

Manage and extend CI/CD pipelines; write safety gates, linting, and automated test hooks

Contribute to ClickHouse schema design, query optimisation, and partitioning strategies for analytics at billion‑row scale

Support MySQL database operations including schema migrations, query tuning, and partition management

Assist in RabbitMQ queue infrastructure management and HAProxy configuration as required

AI Agents & Tooling

Build and maintain AI agent infrastructure (QA Agent, Code Review Agent, SRE Agent) using MCP‑first architecture with Claude via the Anthropic API

Write and maintain CLAUDE.md constitutions, sprint SOPs, and developer scaffolding tooling

Contribute to the MailerCloud MCP connector and associated developer documentation

Code Quality & Collaboration

Participate actively in code reviews, sprint planning, and retrospectives

Write clean, well‑tested, well‑documented code with an emphasis on maintainability at scale

Follow and improve the team's coding standards, branching strategies, and deployment practices

Must‑Have

3 – 4 years of professional software development experience in a product company environment

Familiarity with CI/CD practices (GitHub Actions, GitLab CI, or equivalent)

Strong fundamentals in data structures, algorithms, and system design

Ability to read and understand infrastructure‑as‑code and deployment scripts

Good written English for documentation, PRDs, and async communication
