Summary

Hands-on founding engineer who builds and automates low-level infrastructure: hardened nftables/Ansible firewall setups, containers, local LLM agent runtimes on bare-metal GPU clusters, PostgreSQL audit ledgers, and WireGuard mesh networking. Pure IC role with no management overhead.

Compensation: $100k – $150k • 0.01% – 1.0%

The Role We are looking for a Founding Engineer—a pure, hands-on individual contributor who loves working low in the stack. You will build and automate the core software, firewall, container, and AI agent runtimes that run on our bare-metal GPU clusters and secure laptop terminals. There are no management meetings or slide decks in this role: you write code, deploy Ansible playbooks, and ship production systems. What You’ll Do Automate Firewall & System Hardening: Build declarative Ansible/Cloud-Init playbooks to purge ufw and deploy native nftables rulesets across bare-metal nodes and laptops. Deploy Local AI & Agent Workspaces: Package and containerize local LLM stacks (AnythingLLM, Qwen2.5), optical processing engines (OCRMyPDF), and NVIDIA OpenShell / NemoClaw sandboxes. Hands-on experience deploying and tuning GPU-accelerated workloads (CUDA, vLLM, TensorRT) and automated NVIDIA/ROCm container driver configurations. Build Audit Ledgers: Implement PostgreSQL database schemas and automated logging daemons that capture chronological system events for GxP compliance. Network Mesh Integration: Write automation scripts to enroll host nodes into Headscale/Tailscale WireGuard overlay networks with strict loopback and mesh whitelisting. Remote Provisioning Execution: Drive bare-metal OS provisioning workflows via BMC/IPMI virtual media, PXE boot, and remote TPM unseal scripts. What We’re Looking For Linux Systems Mastery: Extensive experience with Linux administration, shell scripting, systemd, and nftables kernel packet filtering. Container & Automation Proficiency: Strong experience writing Ansible roles, Cloud-Init scripts, Docker Compose files, and PostgreSQL database queries. Low-Level Security Mindset: Familiarity with TPM 2.0 PCR binding, LUKS drive encryption, and sandboxing untrusted Python execution environments. Independent Execution: Ability to take direct technical specifications, build working prototypes, and ship reliable code without hand-holding. Tech Stack Linux, Ansible, nftables, Docker / Docker Compose, Headscale / Tailscale, PostgreSQL, Python, Bash, NVIDIA OpenShell, IPMI / Redfish. CUDA, MXL, ROCm, vLLM, TensorRT.
