Senior Back - End Developer specializing in Backbase digital banking solutions at Aequilibrium, working collaboratively to deliver secure and modern banking experiences.
About the role
- Senior Software Engineer II, Rust developing high-performance services in a multi-language platform while collaborating with teams to ensure product quality at Narvar.
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
Requirements
- 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
