Sr. Software Engineer II (Rust)

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.

• 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
  

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
  

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.)

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.

• 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
