About Elastics

Elastics is building an AI trading assistant for Hyperliquid and Polymarket. We raised a $2M pre-seed led by Frst, with angels from ElevenLabs, XBTO, RedStone and a16z Scout, among others. The product is live in private beta, and it runs on a platform that is already in production and defined entirely in code. Now we need a Head of Infrastructure and Security to make that platform ready for what comes next.

The role

You'll own the platform the trading system runs on, and the security of everything it touches: cloud, Kubernetes, streaming data, secrets and web3 wallets. The system runs live strategies, so an outage or a leaked key costs real money. You'll be accountable for both reliability and security, and you'll stay hands-on in Terraform and code.

The platform you'll own

Everything below is already running in production and defined in code.

Cloud: multi-account AWS Organization with separate production, development, security and shared-services accounts, all in Terraform.
Compute: EKS with Karpenter, running 40+ services deployed through Flux GitOps.
Data: Kafka (MSK), Postgres (RDS), ClickHouse Cloud and Valkey, carrying real-time market data, orders and portfolios.
Orchestration: self-hosted Temporal for workflow orchestration.
Observability: VictoriaMetrics, Grafana, Alertmanager and Better Stack.
Edge and access: Cloudflare at the edge, ingress moving to Gateway API, SSO and private networking for internal tools.
Web3: user wallets, on-chain data and bridging.
AI tooling: an MCP gateway that gives agents controlled access to internal systems.

What you'll do

Infrastructure: own the AWS and Kubernetes platform end to end, including architecture, roadmap, upgrades and capacity. Set reliability targets for market data and execution, and run on-call, incident response and post-mortems. Own backup, disaster recovery and failover for stateful systems. Improve Terraform workflows, GitOps, CI/CD and release safety, and keep cloud spend accountable as usage grows.
Security: build the security program from threat model to roadmap, and be accountable for it. Enforce least privilege across IAM, Kubernetes and service-to-service traffic. Build threat detection, audit logging and incident response across cloud, cluster and CI/CD. Harden the software supply chain with image and dependency scanning, signing and pipeline permissions. Define guardrails for AI agents: what they can access, what they can execute, and how every action is audited.
Building: support the team in feature building, pull request reviews and our AI software factory.
