Job description

VergeCloud is looking for a hands-on System Engineer to work on the core of our CDN and edge infrastructure platform. This role is ideal for an engineer who enjoys building high-performance, low-latency, secure systems close to the network, operating system, and runtime layer.

You will contribute directly to VergeCloud’s CDN core, including request processing, caching, reverse proxying, traffic routing, TLS handling, DNS integration, observability, WAF, rate limiting, bot mitigation, and DDoS protection capabilities.

The ideal candidate should be comfortable writing production-grade Rust code and working with distributed infrastructure that handles high-volume internet traffic across edge locations.

Key responsibilities include:

Develop and maintain CDN core services using Rust.

Build high-performance caching, proxying, routing, and traffic management components.

Work on HTTP, HTTPS, TLS, TCP/IP, UDP, DNS, and edge networking systems.

Improve CDN performance, reliability, scalability, and resource efficiency.

Contribute to WAF, rate limiting, bot mitigation, and DDoS protection features.

Debug production issues across CDN edge nodes, origin connectivity, cache behavior, DNS, TLS, and network paths.

Work closely with SRE, security, and platform teams to build reliable edge infrastructure.

Requirements

5+ years of experience in systems engineering, infrastructure engineering, platform engineering, or backend engineering.

Strong production-level programming experience in Rust.

Strong understanding of Linux systems, networking, processes, memory, filesystems, performance tuning, and troubleshooting.

Deep knowledge of TCP/IP, UDP, HTTP, HTTPS, TLS/SSL, and DNS.

Experience building high-performance, concurrent, asynchronous, or event-driven systems.

Understanding of caching, reverse proxying, load balancing, request routing, and traffic management.

Experience debugging complex production issues across application, network, operating system, and infrastructure layers.

Good understanding of distributed systems, high availability, fault tolerance, and scalable service design.

Experience with logs, metrics, tracing, monitoring, and production observability.

Preferred skills:

Experience with CDN, edge computing, WAF, API gateway, reverse proxy, load balancer, or DDoS protection platforms.

Familiarity with Tokio or other async Rust runtimes.

Knowledge of NGINX, Envoy, HAProxy, Varnish, OpenResty, or similar technologies.

Knowledge of BGP, Anycast, traffic engineering, and global routing.

Experience with eBPF, XDP, DPDK, or kernel-level networking.

Familiarity with Kafka, ClickHouse, Redis, object storage, and large-scale log pipelines.

Understanding of OWASP CRS, ModSecurity concepts, bot mitigation, rate limiting, and application security.

Exposure to WebAssembly, V8, or edge function runtimes.

Opportunity to work on the core technology of a deep-tech edge cloud platform.

Build CDN, DNS, WAF, DDoS protection, video delivery, and edge computing infrastructure from India for global customers.

High ownership role with direct impact on platform architecture, performance, reliability, and security.

Work on challenging systems engineering problems involving Rust, Linux, networking, distributed systems, and high-scale traffic.

Collaborate with a strong technical team across platform engineering, SRE, security, and product.

Exposure to production-scale internet infrastructure, edge networking, caching, traffic routing, and security systems.

Opportunity to grow into senior engineering, platform architecture, or infrastructure leadership roles.

Competitive compensation based on experience and expertise.

On-site collaboration in Bangalore with a fast-moving engineering team.
