Doubling is building a new mobile product in the health and wellness space. Small founding team, mission-driven, 0-to-1 stage.
We're looking for a Design Engineer to own the mobile UX end-to-end: product design, motion / interaction design, and code contributions where it helps the team move faster. The core of the role is product and motion design; code contributions are valued but not the primary skill we're hiring for.
Stack / tools: Figma, React Native, plus at least one motion or prototyping tool (Rive, Lottie, After Effects, Principle, or Framer).
What we want: 2+ years combined in product design and motion / interaction design, at least one shipped mobile product, a portfolio that demonstrates both UI and motion work, and enough comfort in a frontend codebase to land small UI tweaks and animations (or genuine interest in growing into that).
Bonus: prior consumer health, wellness, fitness, or nutrition product experience; design system ownership; founding / first designer at a startup.
Must be authorized to work in the U.S. as an independent contractor. No visa sponsorship for this role.

We run a worker wellbeing and compliance platform used by global buyers and their supply chain sites across Asia. We're in the middle of a meaningful migration and platform buildout — you'd be joining at a point where architectural decisions matter and your fingerprints will be on the system for years.
*The work:* Our stack is Django + Python on the backend, dbt for data transformation, React/Next.js on web, and Expo/React Native for mobile. We run on AWS and Azure. Right now we're migrating legacy services while simultaneously shipping new features — so you'll need to be comfortable holding both in your head.
*What we're looking for:*
- Strong Python/Django chops — you've built and maintained production APIs, not just tutorials - Comfortable with React/Next.js; bonus if you've touched Expo or React Native - You understand what a data pipeline actually does (dbt experience a plus, but SQL fluency matters more) - Cloud experience on AWS or Azure — not ops, but enough to not be blocked - You care about code quality without being precious about it
*What this isn't:* This isn't a greenfield startup with infinite runway. It's a real product with real users, real technical debt, and a migration in progress. If that sounds like a problem, this role isn't for you. If that sounds like the most interesting kind of work, let's talk.
*Details:* - Fully remote, India-based - Senior Software Engineer title

I am six interviews deep into candidates reading me AWS product pages after being asked about their approach to enrichment. If you have ever debugged something in production and have an opinion about literally anything, please talk to me. If you're interested: resume to eng.hiring@sonarmd.com.
If you're really interested: send a cover letter in .md format (no AI, I will know) with answers to: - Last 3 things you personally shipped to prod, preferably ones that failed or had unexpected results - Most recent thing you learned but are too embarrassed to admit you didn't already know - Your 3 biggest pain points working with AI/LLMs/agents - Most recent thing you built that you're legitimately proud of - Preferred tech stack - How many full, 8-hour-day, 5-day-a-week production shipping years you got under your belt, for real
The .md skips the line. I'll read it before anything else in the inbox.
