We’re working with a pre-seed, Toronto-based AI SaaS company backed by top early-stage investors (they’ve raised ~$3M to date). The founding team are repeat operators with deep product and startup experience, and they’re building a platform that turns conversations, emails, and notes into structured workflows — helping advisors eliminate admin and deliver personalization at scale. The product is live with early traction, and they’re now hiring a Fullstack Software Engineer to join their small, fast-moving team.

- Build core product features across both the backend and frontend
- Work with React, TypeScript, and GraphQL to develop clean, performant UIs
- Contribute to backend infrastructure in Ruby on Rails, powering LLM workflows
- Integrate with tools like Zoom, Gmail, and Salesforce

- 4–6 years of experience building fullstack web apps
- Strong experience with React, TypeScript, and GraphQL

- Appreciation for clean UI, strong UX instincts, and component architecture
- Interest in building AI-native products and shipping early-stage software
- Someone collaborative, curious, and excited to move fast in a high-trust environment
- Nice to Have: GCP experience, LLM integration work, or prior SaaS product exposure
Why You’ll Want to Join:
- Founding team with deep product and startup experience
- High ownership: shape both product and codebase from day one
- Real-world AI use case, already gaining market traction
- Backed by respected early-stage investors
- Competitive compensation + equity
$150,000 - $200,000 a year
