About The Position

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. 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? We're on a mission to simplify the everyday lives of consumers. Post-purchase is a critical phase of the customer journey. That's why we created Narvar - a platform focused on driving customer loyalty through seamless post-purchase experiences that allow retailers to retain, engage, and delight customers. If you've ever bought something online, there's a good chance you've used our platform! From the hottest new direct-to-consumer companies to retail’s most renowned brands, Narvar works with GameStop, Neiman Marcus, Sonos, Nike, and 1300+ + other brands. With hubs in San Francisco, Atlanta, London, and Bangalore, we've served over 125 million consumers worldwide across 10+ billion interactions, 38 countries, and 55 languages. Pioneering the post-purchase movement means navigating into the unknown. Our team thrives on this sense of adventure while nurturing a mindset of innovation. We're a home for big hearts and we leave our egos at the door. We work hard but we always make time to celebrate professional wins, baby showers, birthday parties, and everything in between. We are an equal-opportunity employer and value diversity at our company. We do not discriminate on the basis of race, religion, color, national origin, gender, sexual orientation, age, marital status, veteran status, or disability status.

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

Nice To Haves

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

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
