Senior Full-Stack Engineer (Remote – Canada)

About Proof

Proof is a rapidly growing legal tech startup modernizing how law firms operate. Our platform is trusted by thousands of firms across the U.S. and is experiencing rapid month-over-month growth. As we scale, we’re looking for a Senior Full-Stack Engineer to help us build robust, scalable systems and deliver impactful product experiences.

This is an opportunity to join a product-driven, engineering-led team where your work will directly shape the trajectory of a category-defining platform.

What You’ll Do

• Build full-stack features across our platform—from backend services to frontend interfaces—driving initiatives from design to deployment.

• Architect and maintain backend systems in Go (Golang), optimizing for performance, scalability, and operational resilience.

• Develop modern, responsive UIs in React and TypeScript that meet high standards for usability, accessibility, and polish.

• Design clean, intuitive APIs, primarily using GraphQL, and contribute to best practices in API versioning, error handling, and schema design.

• Identify and resolve performance bottlenecks, data issues, and system reliability gaps across the stack.

• Lead design discussions and technical planning, contributing to architectural decisions and long-term platform strategy.

• Mentor engineers, provide thoughtful code reviews, and raise the bar for technical excellence across the team.

• Partner with DevOps to ensure smooth CI/CD pipelines, observability, and operational readiness for production systems.

What We’re Looking For

• 6+ years of hands-on full-stack experience, ideally building high-impact features in fast-paced product environments.

• Proficiency in Go (or equivalent backend experience) and eagerness to work in a strongly-typed, compiled language.

• Deep experience with React and TypeScript, including component architecture, state management, and performance optimization.

• Solid understanding of GraphQL or REST API design, with practical experience building and consuming APIs in production.

• Familiarity with cloud-native systems, preferably on AWS, and a pragmatic approach to scalability and infrastructure.

• Strong database skills, including schema design, performance tuning, and transactional thinking (SQL or NoSQL).

• Commitment to quality, with a track record of writing well-tested, maintainable code and improving system observability.

• Excellent communication skills, especially in distributed, remote-first teams. You can lead conversations and drive clarity.

• A product mindset—you care about the “why” behind your work and are comfortable collaborating cross-functionally.

Nice to Have

• Experience contributing to or maintaining design systems or frontend infrastructure.

• Familiarity with tools like Docker, Terraform, Datadog, Sentry, or similar.

• Prior work in a high-growth startup or SaaS environment.

What We Offer

• Full-time, permanent role

• Remote-first (Canada-based)

• Flexible paid time off, including national holidays

• Competitive salary: $140,000–$180,000 CAD, commensurate with experience 

• Comprehensive benefits: health, dental, vision, and disability insurance

• Company-provided equipment and a home office setup allowance

At Proof, we move quickly, solve real problems, and value engineers who take ownership and bring craft to their work. If you’re looking to join a high-caliber team and help shape the future of legal tech, we’d love to hear from you.
