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 MailerClouds 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.

• 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 MailerClouds 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 → implementation → testing → deployment → 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 teams coding standards, branching strategies, and deployment practices
• Proactively identify technical debt and propose pragmatic refactoring approaches

Required Skills & Experience

Must-Have

• 3 – 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 — schema design, query optimization, indexing strategies
• Experience with Linux (CentOS / RHEL / Rocky Linux or similar) — 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 — 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 — you know when to be perfect and when to be fast
• You are curious about the systems you build on; you dont 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
• What We Offer

• High-impact work at scale

Your code runs on 1B+ emails/month from day one

• AI-first engineering culture

Work with cutting-edge AI agent tooling and MCP architecture

• Direct ownership & growth

Clear career path from SE → Senior → Lead in a growing product company

• Global product, local team

UK-registered, Kozhikode-based team; work on a globally used product

• Competitive compensation

Market-aligned salary with performance reviews and growth-linked increments

• Modern, evolving stack

  Go migration, ClickHouse analytics, Vue 3, MCP agents — never stagnant

• How to Apply
• Send Your Resume And a Brief Note On a Project You Are Most Proud Of (what You Built, What The Scale Was, What You Learned) To
