Senior Software Developer, Rust

We’re introducing Rust where correctness, performance, and reliability truly matter. Narvar is Growing! Narvar is a multi-language platform, and we’re intentional about where we apply Rust. We’re looking for senior engineers to help us bring Rust into the backbone of the system — the parts that must be fast, safe, and correct under real-world scale. This role is for engineers who want agency: people who enjoy identifying the right problems, choosing the right tools, and owning systems end-to-end. You won’t be handed a narrow ticket queue. You’ll help decide what gets built and how it should be built. For this role, you should be located in Canada and able to work within EST/EDT or PDT/PST hours. We are fully remote. Day-to-day • Design and build high-correctness Rust services that sit on critical platform paths • Introduce Rust into areas where safety, determinism, and performance are essential • Own systems from architecture → implementation → rollout → operations • Make real decisions around concurrency, async boundaries, data integrity, and failure modes • Work across service boundaries in a polyglot environment (Rust alongside other stacks) • Collaborate with product, design, and frontend engineers to build systems that are technically sound and product-aware • Improve reliability, observability, and system behavior through design, not just patching • Mentor other engineers and raise the bar on system quality and ownership What We’re Looking For We care more about judgment and ownership than credentials. You’re likely a strong fit if you: • Have built and operated distributed systems in production • Have deep hands-on Rust experience (not just experiments or side projects) • Understand where Rust shines — and where it doesn’t • Are comfortable reasoning about concurrency, async systems, and correctness guarantees • Have experience designing APIs and data contracts that evolve safely over time • Have worked with relational and/or NoSQL databases at scale • Have deployed and operated services in AWS or GCP (We are a GCP Shop though!) • Take initiative naturally and are comfortable operating with ambiguity • Communicate clearly and make tradeoffs explicit Bonus Points These aren’t hard requirements, but strong indicators: • You’ve worked in startup or high-ownership environments • You’ve owned systems in production, including on-call responsibility • You’re comfortable moving across the stack when needed (backend-first, full-stack aware) • You’ve influenced architecture by earning trust, not by mandate • You use modern tooling (including AI-assisted workflows) to increase leverage , not outsource thinking (Note: we care about outcome and judgment, not how flashy your tools are.) Why Rust at Narvar? Because some parts of the system deserve stronger guarantees. We use Rust where: • Bugs are expensive • Latency and throughput matter • Safety and correctness are non-negotiable You’ll help define where Rust belongs , not just write Rust in isolation. Why Narvar (From an Engineer’s Perspective)? • Real scale, real customers, real impacts • Startup-level ownership with platform-level impact • Teams that value thinking, judgment, and responsibility Low ego, high trust, and room to do your best work Why Narvar?
