Senior Software Engineer Newmarket

Principal Rust Engineer - Up to $280,000 Base Salary + Benefits (Remote in the U.S. - Pacific or Mountain Time Zones Required) A leading SaaS company is seeking a Principal Rust Engineer to shape the core architecture of a groundbreaking enterprise platform from its inception. This greenfield opportunity lies within a high-growth organization with over 6,500 employees and billions in annual revenue. The platform is in its early stages, and the company is assembling a small, elite team of Rust engineers to define its future. Starting with a core group of 8 engineers, the team is set to scale to 100, with the Principal Rust Engineer playing a central role in this expansion. Why This Role Stands Out: The engineer will be a foundational contributor, shaping the platform’s direction from the outset. They will leverage Rust, with a focus on Async Tokio, to build a robust, scalable technology stack. They will influence critical decisions on architecture, observability, testing, and reliability. The role offers the agility of a startup-like workplace within the stability of a well-funded enterprise. The engineer will mentor team members, conduct technical reviews, and drive the platform’s long-term vision. Qualifications Sought: Proven experience in building and scaling multi-tenant SaaS enterprise platforms. Deep expertise in Rust, particularly Async programming, combined with a robust systems background (experience in C, C++, or low-level Java is advantageous). A demonstrated history of guiding systems from initial design through production and ongoing maintenance. Comfort operating in ambiguous, fast-paced settings with evolving priorities. Ability to balance technical execution with strategic, product-focused thinking. Compensation & Perks: Base salary: $150,000 - $285,000 (based on experience and location). Bonus and/or equity potential. Comprehensive health benefits: medical, dental, vision, and life insurance. Generous PTO and company-paid holidays. Apply on Kit Job: kitjob.ca/job/2oj6za
