- Develop, qualify, and refine manufacturing processes and subsequent work instructions to meet all design and business requirements, including safety, quality, efficiency, and delivery
- Collaborate with other engineers, subject matter experts, and technicians to solve both internal and customer production challenges
- Work with product engineering team to evaluate designs for manufacturability and implementation in a rapidly evolving production environment
- Resolve product non-conformances and collaborate with the quality team to implement root cause corrective actions
- Identify, plan, and execute capital equipment, machine, and layout upgrades to meet our growing production demand
- Develop and refine floor layouts, capacity models, and product flow analysis to ensure on-time product delivery to our customers

Must-Haves

## About Critical Loop

## Core Business
- **Primary industry**: Energy infrastructure, distributed energy resources (DER), battery energy storage systems (BESS), microgrids.
- **Target customers**: B2B / enterprise – industrial manufacturing, data centers, utilities, critical infrastructure, and EV fleet operators.
- **Mission**: “We’re building a world where energy is abundant and accessible on demand.” The company also states it aims to “accelerate access to reliable power, even where it’s otherwise impossible.” [criticalloop.com](https://www.criticalloop.com/about)

## Products & Services
- **Modular Battery Storage Systems**: Relocatable, megawatt-scale batteries that can be deployed in weeks to provide fast, flexible capacity.
- **Microgrid Cabinet**: A smart, scalable cabinet that integrates different power sources (grid, battery, renewables) into a single controlled system.
- **Control Software**: Proprietary platform for orchestrating power sources, real-time monitoring, diagnostics, and optimization.
- **Full‑Spectrum Energy Solutions**: End‑to‑end project development including financing, design, permitting, deployment, and ongoing operations & maintenance.

## Market Standing
- **Valuation / Market Cap**: Not disclosed.
- **Key Metric**: 50 MWh deployed, scaling to 100+ MWh in 2026, with a stated path to 5–10 GWh within five years. The company operates 55+ active control nodes under actual utility contracts. [criticalloop.com](https://www.criticalloop.com/)
- **Notable Investors / Partners**: Not publicly disclosed. The team includes former leaders from SpaceX, Palantir, Tesla, and Rivian, and the company works with “blue‑chip customers” and utilities.
- **Growth Signals**: Rapid scaling of deployed capacity; 67 employees (as of mid‑2026); active hiring across hardware, software, and business development roles; operating in California with utility contracts.

## Competitive Advantages
- **Speed to power**: “Get megawatts in weeks, not years” – a key differentiator in a market where grid interconnection often takes 5+ years.
- **Configurable platform**: Combines grid power with a proprietary battery fleet, allowing the same hardware/software stack to serve multiple industries (manufacturing, data centers, utilities, etc.).
- **Aerospace‑level engineering**: Founding team from SpaceX, Palantir, and Tesla brings rigor in safety, reliability, and system integration.
- **Proven in the field**: Systems already deployed in extreme conditions with real utility contracts, not just prototypes.

## Strategic Focus
- **Current priorities**: Scale deployed capacity to 100+ MWh in 2026, expand industrial customer base, and deepen partnerships with utilities to close grid gaps. The company is solving the “time‑to‑power” problem that limits business growth in the U.S.

## Why Work Here
- **Culture**: “No endless meetings. No busywork. Just real problems, real ownership, and shipping things that matter.” Early‑stage, fast‑paced environment with a bias toward action. [criticalloop.com/careers](https://www.criticalloop.com/careers)
- **Location & work model**: Engineering roles (Senior Mechanical Engineer, Senior Electrical Engineer, Hardware Technical Program Manager) are listed as “Long Beach (On‑site).” Other roles may vary.
- **Notable perks**:
  - Equity ownership (stock options) for all team members.
  - 401(k) retirement savings plan.
  - Individual Coverage Health Reimbursement Arrangement (ICHRA) – a monthly allowance to choose health, dental, and vision plans.
  - Generous paid time off (unlimited for some roles, 15 days for others) and unlimited sick leave.
