We’re introducing Rust where correctness, performance, and reliability truly matter. 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. What You’ll Work On: - 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 s...
