Role Overview

We are looking for a Senior Software Engineer to join our platform team and take ownership of our container infrastructure and cloud-native networking stack. You will work across Kubernetes networking, policy enforcement, eBPF-based tooling, and service mesh technologies to deliver robust network segmentation and observability across diverse environments.

This is a hands-on engineering role with a high degree of autonomy. You will operate in a lean, fast-moving team where initiative and adaptability matter more than process. If you are energised by hard infrastructure problems and want to build platforms that are secure, observable, and scalable, this role is for you.

Roles and Responsibilities

• Design and maintain production-grade container orchestration platforms using Kubernetes, Docker, and related cloud-native tooling.
• Implement and operationalise network segmentation strategies across containerised environments, leveraging service mesh technologies, network policies, and CNI capabilities.
• Evaluate and integrate policy-as-code frameworks such as Open Policy Agent for admission control, runtime enforcement, and compliance.
• Apply eBPF-based tooling for networking, observability, and security use cases including traffic visibility, kernel-level filtering, and runtime monitoring.
• Build and maintain monitoring, logging, and alerting stacks purpose-built for containerised and distributed environments.
• Define and implement ingress/egress controls, network policy patterns, and zero-trust networking principles within and across clusters.
• Collaborate with development and security teams to ensure consistent, enforceable network boundaries across heterogeneous infrastructure.
• Troubleshoot complex distributed systems issues spanning networking layers, container runtimes, and orchestration control planes.
• Contribute to architecture decisions and build-vs-buy evaluations for platform and networking tooling.

Required Qualification

• 5+ years of hands-on experience with container technologies (Docker, containerd) and Kubernetes in production environments.
• Strong understanding of Kubernetes networking: CNI plugins, network policies, DNS, ingress controllers, and kube-proxy alternatives.
• Experience leveraging service mesh solutions to achieve network segmentation, traffic management, and mutual TLS across services.
• Working knowledge of eBPF and its practical applications in networking, observability, and security.
• Experience with policy enforcement tooling such as OPA/Rego for admission control and compliance-as-code.
• Solid understanding of distributed systems principles: fault tolerance, consensus, event-driven architectures, and eventual consistency.
• Proficiency in at least one systems-level language (Go, Rust, C) and one scripting language (Python, Bash).
• Experience with observability tooling: metrics, distributed tracing, and log aggregation in containerised environments.
• Strong foundation in networking fundamentals: TCP/IP, DNS, HTTP/gRPC, load balancing, firewalls, and VPNs.

Preferred Qualification

• Experience with cloud platforms (AWS, GCP, Azure) and their managed Kubernetes offerings.
• Familiarity with AI/ML infrastructure and workload orchestration on Kubernetes.
• Contributions to open-source projects in the cloud-native ecosystem.
• Experience with GitOps workflows and infrastructure-as-code tools (Terraform, Pulumi, or similar).
• Background in firewall technologies, network segmentation beyond containers, and security compliance frameworks.

What we look for

Beyond technical skills, we value the following traits and working style:

• Self-driven and autonomous: you take ownership from problem identification through to production delivery without needing to be directed.
• Comfortable with ambiguity and rapid context-switching in a fast-paced, startup-style environment.
• A builder mindset — you ship iteratively, learn quickly, and know when good enough is good enough.
• Collaborative with strong opinions loosely held; you challenge ideas constructively and welcome being challenged.
• Curious and adaptable, with a genuine interest in the evolving cloud-native landscape.
