Senior Fullstack Software Engineer

This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Senior Fullstack Software Engineer based in Canada.

This Senior Fullstack Software Engineer role offers the opportunity to build and scale high-impact web applications that modernize how businesses manage complex operational workflows. You will work across the full stack to design and deliver performant, scalable, and intuitive product experiences, with a strong emphasis on frontend architecture and user experience quality. Operating in a fast-moving, product-driven environment, you will collaborate closely with Product, Design, and subject-matter experts to turn ambiguous requirements into well-structured, shippable solutions. The role blends hands-on engineering with architectural thinking, allowing you to influence both technical direction and product evolution. You will also leverage modern AI-assisted development workflows to accelerate delivery while maintaining strong engineering standards. This is a high-ownership role where your contributions directly shape platform scalability, usability, and long-term technical direction.

• Design, develop, and maintain fullstack features using React, Next.js, TypeScript, NestJS, and PostgreSQL.
• Build scalable, high-performance frontend systems with strong component architecture and reusable design systems.
• Own features end-to-end, from discovery and design collaboration through development, testing, and production deployment.
• Collaborate closely with Product, Design, and cross-functional stakeholders to define requirements and deliver high-impact solutions.
• Apply AI-assisted development tools (e.g., Cursor, Claude Code) to accelerate prototyping, debugging, and code optimization.
• Contribute to engineering standards, code reviews, RFCs, and system design discussions.
• Ensure high-quality software through strong testing practices (unit, integration, and end-to-end testing).
• Break down complex technical challenges into clear, iterative, and production-ready deliverables.

Requirements:

• 6–10+ years of software engineering experience building modern web applications.
• Strong expertise in React, TypeScript, and Next.js, with additional experience in backend development (NestJS preferred).
• Solid understanding of relational databases such as PostgreSQL and API-driven architectures.
• Proven ability to design and scale frontend systems, including state management and performance optimization.
• Experience delivering complex features end-to-end in fast-paced, ambiguous environments.
• Familiarity with AI-assisted development workflows and tools such as Cursor or Claude Code.
• Strong understanding of testing strategies, CI/CD pipelines, and software quality best practices.
• Excellent communication skills with a collaborative, ownership-driven mindset.
• Experience working with design systems, internal tools, or SaaS platforms is a plus.

Benefits:

• Competitive compensation aligned with experience and market benchmarks.
• Remote-first work environment with flexible working hours.
• Comprehensive health, dental, and vision coverage.
• Health and wellness spending account to support personal wellbeing.
• Extended parental leave and employee assistance programs.
• Unlimited flexible time off with a trust-based culture.
• Professional growth opportunities including mentorship and continuous learning support.
• Opportunity to work on high-impact, product-driven engineering challenges in a fast-growing environment.
