About Harbinger

Harbinger is an American commercial electric vehicle (EV) company on a mission to transform an industry starving for innovation. Harbinger’s best-in-class team of EV, battery, and drivetrain experts have pooled their deep experience to bring a first-of-its-kind EV platform to support the growing demand for medium-duty EVs and Hybrids. Harbinger: Familiar Form, Revolutionary Foundation.

We are looking for a Senior Systems Engineer to serve as the primary infrastructure engineer across our cloud and on-premises environments. This role owns the architecture and operations of systems supporting both our corporate workforce and our manufacturing facilities, including the production floor, IoT-connected tooling, and the Manufacturing Execution System (MES). This is a hands-on, broad-scope role. You will design cloud architecture in AWS, manage physical infrastructure in our IDFs and server rooms, and connect our sites together with a secure, scalable
network. You should be comfortable moving between writing Terraform, racking hardware, and troubleshooting production issues that affect real vehicles being built.

What You'll Do

  • Own cloud and on-premises infrastructure architecture across corporate and manufacturing environments.
  • Architect and operate a multi-region, multi-account AWS environment using Terraform as the foundation for company-wide workloads.
  • Design and maintain a hub-and-spoke network across 4+ physical locations using AWS Transit Gateway and site-to-site VPN tunnels, with centralized routing and security controls.
  • Maintain a hierarchical IP addressing schema spanning cloud and on-prem to prevent routing conflicts and support third-party integrations.
  • Design and operate highly available infrastructure for the Manufacturing Execution System (MES) supporting 80+ workstations and 30+ IoT-connected tools across production, staging, and development.
  • Integrate EV charging infrastructure and build custom IoT monitoring for critical factory, facilities, and warehouse systems to reduce operational risk.
  • Manage physical infrastructure including bare-metal servers, Ubiquiti networking, Synology storage, and UPS-backed IDF/server room environments.
  • Partner with manufacturing, IT, security, and engineering teams to deliver infrastructure that meets uptime and security requirements for a 24/7 production environment.

What We're Looking For

  • 7+ years of systems, infrastructure, or DevOps engineering experience, including ownership of production environments.
  • Strong AWS experience: multi-account architecture, VPC design, Transit Gateway, IAM, and core services (EC2, RDS, S3, ECS, Lambda, CloudWatch).
  • Deep Terraform experience managing infrastructure as code across multiple environments.
  • Solid networking fundamentals: routing, subnetting, VPNs, firewalls, and IP schema design across hybrid environments.
  • Experience with on-premises infrastructure: bare-metal servers, enterprise networking (Ubiquiti, Cisco, or similar), storage, and IDF/server room operations.
  • Scripting and automation skills in Python, Go, or similar.
  • Comfort working in environments where infrastructure issues have direct operational impact (manufacturing, broadcast, trading, healthcare, etc.).

Nice to Have

  • Experience in a manufacturing, industrial, or OT/IoT environment.
  • Familiarity with Manufacturing Execution Systems (MES) or other production-floor software.
  • Experience with Ansible, Packer, and CI/CD tooling (Buildkite, CircleCI, GitHub Actions).
  • Virtualization experience (Proxmox, VMware ESXi).
  • Background supporting a fast-growing startup through scaling phases.
Key Benefits & Perks:
  • Comprehensive Health, Dental & Vision (HDV) – 100% employee covered
  • Early-stage Stock Options
  • Robust Retirement Savings (401k, HSA, FSA)
  • Generous Paid Time Off (PTO) & Parental Leave
  • Annual Vacation Bonus
  • Wellness & Fertility Benefits
  • Cell Phone Stipend
  • Complimentary Meals & Stocked Kitchens

California Pay Range

$120,000 - $150,000 USD

Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 04/30/2026

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
