Lead Infrastructure Engineer (Platform & Kubernetes)

The role

We are looking for a hands-on Lead Infrastructure Engineer to build and own the infrastructure for Rojo's new integration products. You will be our first infrastructure hire and will be responsible for the Kubernetes platform, infrastructure as code, messaging, identity, secrets, security and observability.

This is a greenfield build with no legacy systems to work around, so the decisions you make early on will shape the platform for years to come. In the first phase you will be closely involved in the day-to-day work, from writing Terraform and setting up clusters to troubleshooting Kafka. As the product grows, you will build and lead the infrastructure team.

What you need

Who we are looking for

Someone who has built infrastructure from the ground up and owned it in production, whether at a startup, a new product team within a larger organisation, or a venture of their own. You are comfortable making architecture decisions without a detailed roadmap, can explain the trade-offs behind them, and enjoy doing the hands-on work yourself.

This role suits someone who wants broad ownership more than someone looking for a narrowly defined scope within a large platform team.

Must-haves

Experience: 6+ years in infrastructure, platform or SRE roles, including at least one role where you built or rebuilt production infrastructure from the ground up and were responsible for running it.
Kubernetes (Managed & On-Prem): Strong production experience, including multi-tenant isolation (namespaces, NetworkPolicy, ResourceQuota/LimitRange, Pod Security Admission) and autoscaling. Experience with a managed service (EKS, GKE or AKS) as well as a self-hosted or on-prem distribution (e.g., K3s, Rancher, OpenShift).
Hybrid Networking & Connectivity: Experience setting up secure connectivity between cloud control planes and customer-hosted environments (e.g., mTLS, WireGuard/VPN, reverse proxies).
Infrastructure as Code: Modular design, remote state with locking, and state-splitting to limit blast radius. Terraform preferred; experience with OpenTofu, Pulumi or Crossplane is also relevant.
Distributed Messaging: Production experience running a messaging system, including sizing, replication, DLQ and retry handling. Kafka preferred (KRaft is a plus); strong experience with Pulsar, RabbitMQ or NATS is also relevant.
Security: A solid understanding of infrastructure and cloud security, including least-privilege IAM and RBAC, network segmentation, encryption in transit and at rest, container and image hardening, and secrets management (e.g., Vault) with OIDC-based identity (e.g., Keycloak). Familiarity with frameworks such as ISO 27001, SOC 2 or GDPR is a plus.
Leadership & Independence: Experience setting technical direction, documenting and defending architecture decisions, and prioritising work without a predefined roadmap.
