Rust Jobs for Rustaceans

About Nono Network
We are an early‑stage, venture‑backed payments startup on a mission to make global money movement instantaneous, secure, and affordable. Built by alumni from leading fintechs and cloud‑native scale‑ups, we process card and account‑to‑account transactions for merchants in 30+ countries. Regulatory compliance, security‑by‑design, and a developer‑centric culture are the cornerstones of our product and platform.

Key Responsibilities
As a Senior Backend Engineer, you’ll play a critical role in building and scaling our high-performance, serverless infrastructure. Your work will directly power systems handling thousands of payment requests per second, with a strong focus on automation, security and observability.

• Backend Architecture & Development (35%)
  Design and build event-driven microservices using Rust (for high-throughput cores) and TypeScript (for edge and orchestration layers). Architect systems capable of handling thousands of concurrent payment requests per second.
• CI/CD & GitOps Ownership (15%)
  Implement and maintain GitOps workflows using GitHub Actions and Argo CD. Ensure code is deployed to production within 15 minutes of PR merge, with support for automated rollbacks.
• Security & Compliance (15%)
  Embed DevSecOps best practices into the development process. Implement and manage security controls aligned with PCI-DSS v4.0, GDPR, SOC 2, and ISO 27001.
• Infrastructure as Code (10%)
  Automate infrastructure using Terraform and CDK. Maintain repeatable, least-privilege environments across multiple AWS regions.
• Observability & Performance (10%)
  Champion structured logging, distributed tracing, and metrics collection. Benchmark performance to maintain P99 latencies under 100ms.
• API Documentation (10%)
  Generate and maintain OpenAPI 3.1 documentation. Integrate tools like Redocly and Spectral into the CI pipeline for automated API docs.
• Mentorship & Technical Leadership (5%)
  Review pull requests, mentor junior engineers, and contribute to the technical roadmap and coding standards.

Requirements

• 5+ years building cloud‑native back‑end systems in a strongly typed language (Rust, Go, Java, etc.) with at least 1 year production Rust experience.
• Deep knowledge of event‑driven architectures (idempotency, exactly‑once delivery, saga patterns).
• Proven delivery of Serverless or container‑based workloads at scale.
• Hands‑on GitOps & CI/CD mindset (Argo CD, Flux, GitHub Actions) with automated testing & progressive delivery.
• Solid experience with Infrastructure‑as‑Code (Terraform or CDK) and DevSecOps practices—security tests left of boom.
• Experience implementing or operating under PCI‑DSS, GDPR, SOC 2, or ISO 27001 controls.
• Comfortable working in a fast‑moving startup, collaborating asynchronously across time zones.

Bonus Points

• Payments industry background (card acquiring, issuing, open banking).
• Knowledge of Cloudflare Workers/Pages, Durable Objects, and Zero Trust policies.
• Familiarity with Zero‑knowledge or privacy‑enhancing cryptography.
• Community involvement (open‑source maintainer, conference speaker, tech blogger).

What We Offer

• Competitive salary and benefits package.
• Opportunity to work on cutting-edge technologies at the intersection of AI, payment solutions, and event-driven systems.
• Collaborative, fast-paced environment that values innovation and impact.
• Potential for significant influence on product direction and company success.

Hiring Process

• Intro call (30 min) – meet CTO, talk role & culture.
• Technical deep‑dive (90 min) – architecture discussion & code review (no take‑home).
• Pairing session (60 min) – solve a real but small problem together in Rust/TS.
• Founders chat (30 min) – product vision & values fit.
• Offer – references & background check (we’re a regulated entity).
