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.
