Devops Lead

Foundational DevOps / SRE Engineer – Telecom Security Startup

London / Hybrid

Numi are partnered with an exciting early-stage venture backed by leading global telecoms. They’re on a mission to restore trust in voice communication with next-generation network-native security and AI-powered services. This is a foundational hire – you’ll help build the platform, shape the engineering culture, and have real impact from day one.

The Role

This isn’t pipeline maintenance. You’ll take full ownership of platform reliability, performance, and security, powering mission-critical, low-latency products and AI-driven features.

What You’ll Own

• Build and manage cloud infrastructure from scratch with Terraform
• Lead Zero Trust security implementation: micro-segmentation, strict IAM, mTLS, immutable logs
• Design and maintain CI/CD pipelines for microservices
• Own observability and monitoring (Prometheus, Grafana, OpenTelemetry)
• Manage Kubernetes clusters (EKS), real-time data streams (Kafka), and high-performance APIs
• Embed compliance into infrastructure (GDPR, PIPA)
• Co-own incident response and alerting to maintain 99.9%+ uptime

What We’re Looking For

• Extensive experience in DevOps, SRE, or Platform Engineering
• Terraform / IaC expertise
• Strong AWS, Docker, Kubernetes experience
• CI/CD pipeline design experience
• Observability stack experience
• Scripting skills (Python, Go, or similar)

Nice-to-Haves

• Zero Trust / mTLS experience
• Low-latency / high-throughput systems experience
• Apache Kafka expertise
• Kubernetes automation tools (e.g., ArgoCD)

Who You Are

A proactive problem-solver who takes ownership end-to-end, thrives in fast-paced, high-impact environments, and handles sensitive data responsibly.
