About Tone Singleton
Tone Singleton is a technology company building software products across multiple domains, from CRM systems for healthcare clients to mobile learning applications for Mandarin Chinese learners. We operate as a lean engineering team that owns its infrastructure end-to-end, from AWS CDK stacks to end-user interfaces.
The Role
We’re looking for a versatile full-stack engineer to join our small team (currently 3 developers). You’ll work across the entire product lifecycle: designing data models, building backend services, crafting frontends, configuring CI/CD, managing infrastructure, and shipping features to production. This isn’t a role where you write React components all day — you’ll set up Docker containers one morning and design a Microsoft Graph API integration the next.
What You’ll Work On
CRM systems: Vendor and custom, with extensions (PHP/TypeScript).
Websites: Next.js + Tailwind CSS deployed on AWS Amplify. Payload CMS for content management. Storybook for component documentation. SEO and analytics.
Mobile applications: React Native apps. SQLite-based offline-first architecture with Drizzle ORM. iOS deployment via Fastlane.
Developer tooling: Projen-based project scaffolding library that generates standardised TypeScript packages, CDK constructs, Next.js apps, Payload CMS setups, and React Native projects.
Infrastructure: AWS CDK v2 stacks managing multi-account environments, Aurora Serverless PostgreSQL, CloudFront CDN, Route 53, SES email, and Amplify deployments. On-premise VM management with ESXi, Docker, NGINX (SWAG), and Portainer.
Day-to-Day Responsibilities
Design and implement features end-to-end (API → database → UI)
Set up and maintain CI/CD pipelines (GitHub Actions)
Configure production environments including Docker containers, DNS records, and SSL
Write and review pull requests in a trunk-based development workflow (feature branches → develop → main)
Manage dependency updates and security patches
Troubleshoot production issues (connection failures, container lifecycle, build performance)
Build reusable libraries and abstractions (ORM clients, type packages, CDK constructs)
Must-Have
Strong TypeScript proficiency across Node.js and browser/React environments
Experience with Next.js (App Router, server components, middleware)
Comfortable with Docker, Linux server administration, and networking fundamentals (DNS, reverse proxies, SSL)
AWS experience — at minimum: Amplify, S3, CloudFront, RDS/Aurora, SES. CDK knowledge is a strong plus.
GitHub Actions CI/CD pipeline authoring
Ability to work independently, create well-scoped issues, and drive features to completion without hand-holding
Conventional commits and clean PR hygiene
Nice-to-Have
React Native / mobile development experience
PHP experience
Microsoft Azure AD / Graph API / SCIM integration experience
Projen or jsii experience
Payload CMS or similar headless CMS experience
Familiarity with Storybook for component-driven development
AWS CDK v2 with multi-account, multi-environment patterns
SQLite / Drizzle ORM experience
VMware ESXi / on-premise infrastructure management
What We Value
Ownership — you create the issue, implement the feature, deploy it, and verify it works in production.
Perfectionism — we don’t consider it to be a flaw and prefer slower but better.
Breadth — the team is small. You’ll touch PHP, TypeScript, Python, Docker, AWS, NGINX, and more within any given month. Yes, unfortunately this means occasional context-switching that we’re trying to minimise as much as possible.
Clear communication — issues are well-described with context. PRs have descriptive titles. Questions get asked early, not after a week of going in the wrong direction.
How We Work
Small team (you + 3 engineers), flat hierarchy
GitHub-centric: issues with milestones, project boards, typed issues (Bug/Task), Dependabot for automated updates
Projen manages project configuration — no manual package.json edit
