Senior Full Stack Tech Lead, Mill

• 6+ years of professional experience in software development with a focus on full-stack development
• Deep experience with modern frontend frameworks (e.g. React, Vue, Angular, or SvelteKit) — we use SvelteKit at Mill but recognize that strong React/Vue/Angular experience is highly transferable, especially with AI-assisted tooling, so prior SvelteKit experience is preferred but not required
• Strong backend experience with TypeScript/Node.js; comfort with serverless architectures (e.g. AWS Lambda) is a plus
• Solid understanding of SQL and NoSQL database systems
• Experience with cloud platforms (we run AWS) and modern deployment workflows
• Fluency with AI-assisted development workflows (e.g. Claude Code, Copilot) as a genuine part of your day-to-day practice — not occasional or exploratory use
• Strong software architecture fundamentals (e.g. microservices, serverless)
• Excellent problem-solving and debugging skills
• Strong communication and interpersonal skills — especially the ability to partner closely with product without owning the roadmap
• Comfortable holding technical ownership of a project over a sustained period, while staying energized by the opportunity to rotate onto new problems periodically
• Proactive, self-driven, and eager to take ownership of projects
• Passion for mentoring and developing engineering talent

Desirable

• We are seeking a highly skilled Senior Full Stack Tech Lead to join our engineering team
• This is an individual contributor technical leadership role reporting to the Director of Software Engineering
• You will drive the technical direction of your project area, write high-quality code across the stack, and act as the primary technical partner to product management, while mentoring engineers around you
• We've moved away from a frontend/backend split at Mill: every engineer here works full stack, typically leaning toward one side based on strength and interest, and teams are organized around projects rather than layers of the stack
• You'll likely anchor on a given project for a sustained stretch — enough to build real depth and avoid constant context-switching — with real opportunities to rotate onto new projects and parts of the codebase over time
• AI-assisted development is core to how we build software, not a peripheral tool
• We expect fluency with tools like Claude Code as part of your daily workflow, and as a senior level engineer, a role in raising the bar for how the team uses them
• Lead the technical design and execution of full-stack web applications, ensuring alignment with business objectives and technical standards
• Architect and implement scalable, secure, and efficient full-stack solutions
• Evaluate and select technologies, frameworks, and tools — including AI-assisted development tooling — to improve team productivity and code quality
• Own estimates and technical delivery plans for your project area, and surface risks early
• Craft elegant, documented, and sustainable code spanning our full web stack, remaining ready to provide support for our native mobile environment when required
• Develop and optimize APIs, databases, and user interfaces
• Use AI-assisted development tools fluently as a standard part of how you write, review, and ship code
• Mentor engineers, fostering a culture of continuous learning and improvement
• Conduct code reviews and provide constructive feedback to maintain high coding standards
• Act as the primary technical partner to product managers on your project — informing scope, sequencing, and tradeoffs — even though roadmap ownership sits with the PM
• Champion best practices in testing, CI/CD, and deployment
• Troubleshoot and resolve technical issues, ensuring minimal downtime and disruption
• Monitor and optimize application performance
