About the role

Senior Rust Software Developer II building high-correctness services in a polyglot environment for Narvar, a company focused on post-purchase customer experiences.

Responsibilities

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

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
