The Role

You will own the reliability, scalability, and performance of the infrastructure powering our trading strategies. This includes Kubernetes operations, CI/CD systems, observability stack, and networking for high-frequency trading and DeFi strategies. Your work directly impacts latency, uptime, and developer velocity.

What You’ll Do

• Design and evolve our Kubernetes platform: operators, workload orchestration, efficient deployments (blue/green, canary).
• Improve CI/CD pipelines:
  Git Hub Actions, Cloud Build, automated tests, secure image delivery.
• Build and maintain monitoring and incident response:
  Open Telemetry, Prometheus/Alert manager, Loki, Tempo, Thanos/Mimir.
• Maintain network & ingress: NGINX Ingress, Kong Gateway (auth, rate-limit, plugins).
• Manage infrastructure as code:
  Terraform/Ansible for GCP resources.
• Drive Fin Ops: optimize cost of compute, storage, and networking.
• Support development teams: debug performance issues, improve reliability, automate workflows.
• Lead incident response & post-mortems: ensure systems are observable and resilient.

Stack & Infra You’ll Touch

• Platform: GCP + Kubernetes (ArgoCD, Git Hub Actions, Cloud Build)
• Networking: NGINX Ingress, Kong Gateway
• Observability: Open Telemetry, Grafana Alloy, Prometheus, Alert manager, Loki, Tempo, Thanos, Mimir
• Data & Messaging: Kafka (event streams, schema evolution)
• Data stores: Postgres, GCS
• Tooling: Terraform, Ansible, Python/Rust for automation

What We’re Looking For

• 5+ years running production infrastructure at scale.
• Strong experience with Kubernetes (operators, controllers, upgrades).
• Solid background in CI/CD, Git Ops, infrastructure as code.
• Proven record of building reliable, observable systems.

• Strong in at least one systems language (Golang or Rust preferred).
• Cloud (GCP/AWS/Azure) networking and IAM.
• Terraform / Ansible or similar for infra automation.
• Monitoring and tracing (Prometheus, Open Telemetry).
• Incident management and on-call practices.

• Experience in low-latency trading or crypto infra.
• Security hardening (network policies, secrets management, Vault/KMS).
• Performance tuning of Kubernetes and containerized workloads.
• Cost optimization (Fin Ops) at scale.

Why Join Us

• Competitive comp with equity/token upside.
• Ownership of the platform core to trading.
• Remote (±4h CET), lean sharp team, offsites.

Mindset

• End-to-end ownership. Bias to ship with reliability and high standards.
• Calm under pressure, able to debug complex distributed systems.
• Fast learner, curious about infra and trading systems.
