Platform Engineer, Infrastructure

About Helius

Helius is building the core infrastructure for Solana - empowering developers to create the next generation of crypto-powered applications. Our mission is to accelerate the development of internet capital markets by making it easier, faster, and more intuitive to build on-chain.

Thousands of teams - from early-stage startups to industry leaders like Coinbase, Phantom, and Jupiter - rely on Helius APIs, webhooks, and indexing tools to power their products. Backed by Haun Ventures, Founders Fund, and Foundation Capital, we’re a small, senior team obsessed with performance, simplicity, and scalability in decentralized systems.

About the Role

Helius runs its global edge network and high-performance services directly on bare metal. It's a deliberate choice for performance and cost, and it means the machines, the network, and the tooling that ties them together are ours to get right. This role joins our Platform team to make that fleet faster to provision, safer to access, cheaper to run, and boring to deploy to.

You'll work across the foundation everything else at Helius depends on: automating how servers get spun up and configured, standardizing how software gets built and shipped to machines, and executing on our engineering security roadmap. This is an intermediate role with a lot of room to grow. We care more about ownership, intensity, and learning speed than about a perfect match on today's stack.

No crypto background is needed. If you've run serious infrastructure anywhere, we'll teach you the blockchain parts.

- Remote-first flexibility: Work where you’re most effective with a flexible, fully distributed team
- Competitive comp & perks: Market-leading salary, meaningful equity, generous vacation, wellness budgets, and support for learning and travel
- Mission-driven team: Join ambitious builders who move fast, take ownership, and are building infrastructure for internet capital markets

Responsibilities

Automate the server lifecycle end to end: provisioning, OS installs, configuration, hardware validation, and decommissioning; Build and maintain the tooling engineers use to interact with the fleet, so nobody hand-configures a machine twice; Standardize how we build and deploy software to machines: CI pipelines, artifacts, deploy tooling, and rollbacks; Execute security roadmap items alongside our security lead: SSO-integrated access, jump hosts, secrets management, least-privilege access, and audit trails; Run cost analysis across the fleet, including cost per workload, provider comparisons, and hardware refresh decisions, and turn it into recommendations; Improve observability for the infrastructure you own, and take part in on-call and incident response; Write clear runbooks and docs so the rest of a remote team can operate what you build

Requirements

Extreme ownership: you treat the systems you touch as yours, see problems through to the fix, and automate yourself out of repetitive work rather than living with it. You work the way our Manifesto describes (fast, direct, low-ego, and accountable), and that matters to us more than any single item below.; 3+ years in infrastructure, DevOps, SRE, or platform engineering; Hands-on bare metal experience, such as provisioning and managing physical servers (PXE, IPMI/BMC, RAID, NICs), working with colo or dedicated-server providers, and debugging hardware versus software issues; Deep Linux fundamentals, including systemd, networking, storage, and performance tuning; Experience with configuration management and infrastructure-as-code (e.g. Ansible, Terraform, Salt, Nix); Solid scripting or programming ability in Python, Go, Bash, or similar; A security mindset: you think about access, blast radius, and secrets by default, not as an afterthought

Nice to have

Rust experience, or interest in reading and debugging Rust services; High-performance networking or low-latency systems experience; Familiarity with ClickHouse, Prometheus, or Grafana; Experience at a high-scale B2B infrastructure company
