Staff Software Engineer, Email Editing, Fullstack

The Email Editing team owns the creative heart of Mailchimp: the editors millions of customers use to design, personalize, and publish email campaigns that reach hundreds of millions of inboxes. Our work spans the full stack, and then some:

A modern, interactive email editor — a rich React + TypeScript editing experience where customers visually compose, style, and preview their campaigns.

Backend services that validate content, apply brand styling, generate previews, and render customer designs into HTML that displays correctly across notoriously inconsistent email clients.

A large-scale web application serving millions of users, where we modernize long-lived product surfaces while keeping them reliable for the customers who depend on them every day.

AI-powered editing — services that let customers edit their emails in natural language: 'make the header blue and add a Summer Sale banner.'

'Fullstack' is not a buzzword here. In a given quarter you might evolve how email content is structured and stored, optimize the rendering pipeline, ship a new editing interaction in the visual canvas, and improve how our AI features manipulate customer designs — all in service of one editing experience.

Responsibilities

Design, build, and operate features end-to-end across the stack : a rich frontend editing experience, backend content and rendering services, and AI-powered capabilities.

Help set technical direction for how customer email content is structured, validated, and versioned — and evolve those formats without breaking millions of customers' saved campaigns and templates.

Own rendering correctness : turn customer designs into email HTML that renders reliably across Gmail, Outlook, Apple Mail, and the long tail of email clients, while meeting performance and accessibility standards.

Shape our AI editing capabilities : design the interfaces between AI-driven edits and customer content, and hold AI-produced changes to the same quality bar as human-authored ones.

Lead workstreams that modernize legacy technology — migrating customers and their saved content safely to newer experiences, shipped incrementally with controlled rollouts.

Operate what you ship : instrument services with logging, metrics, and tracing; participate in on-call; and use observability data to keep quality high in production.

Build for scale, accessibility, and compliance : millions of users, WCAG accessibility standards, and awareness of email regulations such as GDPR and CAN-SPAM.

Multiply the team : mentor engineers, write clear design documents, raise the bar in code review, and collaborate closely with design, product management, and partner teams across Mailchimp and Intuit.

Champion responsible AI-assisted development — use modern AI tooling to move faster while establishing the practices that keep generated code reviewable and trustworthy.

Qualifications

Required

8+ years of professional software development experience (or equivalent demonstrated ability), including several years building and shipping production web applications at scale.

Hands-on experience building LLM-powered product features : working with agent frameworks, designing tools for AI systems, prompt design, or evaluation pipelines.

Deep expertise in TypeScript/JavaScript and React , including experience building complex, state-heavy user interfaces (editors, canvases, design tools, or comparably interactive products).

Strong server-side engineering experience in at least one of Node.js, PHP, or Python — and genuine willingness to work across more than one, since our stack spans several.

Experience designing, operating, and debugging production APIs and services , including instrumentation, monitoring, and incident response.

A track record of staff-level technical leadership : driving initiatives that span multiple engineers or teams, decomposing large or ambiguous problems, and mentoring others.

Strong testing discipline across unit, integration, and end-to-end levels, and habits that keep large, long-lived codebases healthy.

Excellent written and verbal communication , suited to a distributed team where design docs and async collaboration carry real weight.

Bachelor's degree in Computer Science or a related field, or equivalent practical experience — we care about what you can do, not the path you took to learn it.

Nice to have — none of these are required

Experience with HTML email rendering and its constraints (email client quirks, templating frameworks, deliverability considerations).

Experience building editors or document tooling : rich-text or visual editors, schema-driven UIs, undo/redo systems, or collaborative editing.

Experience leading legacy modernization — incrementally replacing older frameworks or architectures in a system that must stay reliable throughout.

Familiarity with high-scale data and infrastructure : large relational databases, caching, container orchestration, and CI/CD pipelines.

Depth in web accessibility (WCAG) beyond the basics.

Familiarity with email and privacy regulations (GDPR, CAN-SPAM).
