Staff Engineer

About the Client:

Our client is reimagining how businesses build and scale customer communities in a way that transforms passive audiences into engaged advocates, turning community interaction into measurable retention and growth. Backed by Bessemer Venture Partners, they've achieved strong product-market fit and 50% year-over-year growth. Our client is a lean, high-growth environment where AI is core to the roadmap, the team operates with startup hustle, and individual contributors have the opportunity to have impact on both product direction and company trajectory.

The Opportunity:

We are hiring for three Staff Engineering roles: Frontend, Backend, and Fullstack, each requiring strong technical depth and product ownership in their respective domains.

• You will be the first-ever Staff Engineer at a fast growing B2B SaaS startup!
• You will own and build the next generation of products as a Staff Engineer, driving features from early prototype through to production at scale.
• You will lead complex frontend development in TypeScript and React (Next.js), building high-performance, real-time, and AI-powered user experiences.
• You will integrate AI/LLMs into production customer workflows, designing for reliability, trust, and real-world usability beyond demos.
• You will operate across the full stack when needed, making strong architectural decisions and choosing the right level of simplicity vs long-term scalability.
• You will raise the engineering bar through code quality, technical leadership, and mentorship, shaping how the team builds and ships software.
• You will work with high autonomy in a fast-moving environment, partnering closely with Product and Design to turn ambiguous problems into shipped, high-impact solutions.

The Skills/Requirement Needed to Succeed:

• You have 7+ years of software engineering experience, with deep expertise in TypeScript and modern web development across frontend and/or backend systems.
• You have strong experience with TypeScript, React, and Next.js (for frontend/full-stack roles), building scalable, production-grade applications with a focus on performance, maintainability, and UX quality.
• You have strong backend or full-stack experience with TypeScript and Node.js, including designing APIs, working with databases (SQL or NoSQL), and building scalable service architectures.
• You have experience working with distributed or multi-tenant SaaS systems, understanding architectural trade-offs around scalability, reliability, and system design.
• You are comfortable working across the stack when needed, using TypeScript end-to-end, integrating APIs, building features, and debugging complex production issues.
• You have operated at a Senior or Staff level, influencing technical direction, writing high-quality production code in TypeScript, and collaborating closely with Product and Design.
• You’re able to commute to a downtown Toronto office 2–3 days per week.
