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 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.
Role Overview
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.
Core Technology Stack
Go, PHP, Vue 3, MySQL, ClickHouse, RabbitMQ, HAProxy, Rocky Linux 9, Docker, Git/CI-CD
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
Own features end-to-end: requirements â implementation â testing â deployment â monitoring
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
Proactively identify technical debt and propose pragmatic refactoring approaches
Required Skills & Experience
Must-Have
3 â 4 years of professional software development experience in a product company environment
Strong proficiency in at least one backend language: Go (strongly preferred) or PHP
Solid frontend skills in Vue 2/3 or React; comfortable working with component libraries and REST/GraphQL APIs
Working knowledge of MySQL â schema design, query optimization, indexing strategies
Experience with Linux (CentOS / RHEL / Rocky Linux or similar) â comfortable on the command line
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
Nice-to-Have
Experience with ClickHouse, BigQuery, or other columnar databases for analytics at scale
Familiarity with message queues: RabbitMQ, Kafka, or similar
Exposure to HAProxy, Nginx, or load balancer configuration
Experience integrating with email-related protocols or APIs (SMTP, PowerMTA, SendGrid, etc.)
Understanding of email deliverability concepts (SPF, DKIM, DMARC, IP reputation)
Prior work with MCP (Model Context Protocol) or AI-assisted development workflows
Experience integrating with e-commerce, CRM, or marketing platforms where email is a major communication channel
Contributions to open-source projects
Who You Are
You take ownership â when you pick up a task, it gets done
You communicate proactively: blockers, progress, and decisions surface early
You are comfortable with ambiguity and can translate loose requirements into well-scoped technical work
You care about code quality but ship pragmatically â you know when to be perfect and when to be fast
You are curious about the systems you build on; you don't stop at the API boundary
You thrive in a lean team where your work has direct, measurable impact
You are genuinely excited about AI-augmented development and want to work at the frontier of how software gets built
