Descripción del puesto
About Welle
Welle is a next-generation proactive health platform helping people live healthier, longer, and better. We combine advanced diagnostics, personalized therapeutics, and adaptive coaching to deliver whole-health programs for individuals and organizations.
We're a funded, mission-driven team building real products for real users. This is an opportunity to work on meaningful healthcare technology with a team that values ownership, speed, and high standards.
The Role
We're hiring an experienced Full-Stack Developer with strong production experience in Node.js/NestJS, React/Next.js, and JavaScript/TypeScript to help accelerate product delivery and raise the quality bar across our platform.
This is a high-ownership, hands-on engineering role for someone who has already built, shipped, and supported real systems in production. You'll own features end-to-end, contribute to technical decisions, and work closely with a distributed team to turn business needs into reliable, scalable software.
This role is also stakeholder-facing. You should be comfortable joining discovery calls, participating in sprint reviews and demos, and clearly explaining technical tradeoffs to non-technical audiences.
We are not looking for a junior developer, a task-taker, or someone still learning the fundamentals on the job. We're looking for someone who can ramp quickly, operate independently, and ship with confidence.
What You'll Do
- Build and maintain production backend services using Node.js/NestJS
- Own key parts of our React/Next.js application
- Make strong architectural and implementation decisions across frontend and backend
- Ship polished product experiences, including edge cases, loading states, error states, and performance improvements
- Debug issues across application, database, and infrastructure layers
- Collaborate across time zones with strong async communication and clear handoffs
- Participate in discovery, sprint reviews, and demos with internal and external stakeholders
- Own features from planning through launch and production support
We actively use tools like Cursor, GitHub Copilot, and similar AI-assisted workflows to improve speed and code quality. You should be comfortable using AI tools to accelerate development while applying strong engineering judgment, validating outputs, and taking full ownership of what ships.
Required Qualifications
- 5+ years of professional software engineering experience
- Strong hands-on experience building and maintaining production systems
- Strong proficiency in JavaScript and TypeScript
- Strong production experience with:
- React + Next.js
- Prisma + PostgreSQL or similar ORM/relational database stack
- Experience designing and maintaining REST and/or GraphQL APIs
- Strong understanding of:
- frontend architecture and state management
- debugging, reliability, and performance in production environments
- Experience owning systems or features end-to-end for real users
- Excellent written and spoken English
- Comfortable in stakeholder-facing conversations
- Able to overlap 6+ hours/day with Pacific Time
- Docker, Kubernetes, GCP, AWS, or Vercel
- CI/CD pipeline experience
- Monorepo experience
- Experience in agency, consultancy, or other client-facing environments
- Experience working with distributed/global teams
- Experience in healthcare, fintech, or other regulated environments
- Contract: Full-time, 40+ hours/week
- Location: Fully remote
- Timezone: Must overlap at least 6 hours/day with Pacific Time
- Team collaboration: You'll work closely with a distributed international team and should be comfortable with async communication and evening handoffs when needed
- Work on products that meaningfully improve health outcomes
- High ownership and autonomy with a fast-moving team
- Opportunity to shape real systems, not just execute tickets
- Async-first culture focused on clarity, accountability, and deep work
- Competitive compensation, with equity potential for the right candidate
