About Charm
Our mission is to return the atmosphere to 280 ppm CO₂. We convert excess inedible biomass into carbon-rich bio-oil and inject it into underground storage for permanent carbon removal. At scale, we can use bio-oil to make fossil-free iron.
Our carbon removal efforts began in 2020 with initial purchases from customers like Stripe, Shopify, and Microsoft. Since then, we’ve scaled to thousands of tons of carbon removal, grown to over a hundred employees, and established three locations in San Francisco, Colorado, and Louisiana.
We're expanding our team of ambitious, creative, and hands-on problem solvers. We value psychological safety, collaboration, and continuous learning. We take calculated risks and treat mistakes as opportunities to improve. If you're excited about tackling big challenges, we encourage you to explore our company values.
Come help us reverse climate change. Gigatons or bust!
About the Role
Charm is hiring an Enterprise Integration Systems (EIS) Engineer to own the technical infrastructure connecting our core operating systems, including Manufacturo (MFO), NetSuite, Mangrove, and other business-critical platforms.
Reporting to the Lead IT Systems Engineer within Charm’s IT organization, the EIS Engineer owns the integration layer that enables our systems to operate as a connected ecosystem. This includes designing and maintaining integrations, building automation scripts, administering key platforms, monitoring data flows, and resolving anomalies that emerge across system boundaries.
Charm operates under a federated ownership model. Engineering, Operations, MRV, and Finance own their respective data, processes, and business outcomes. The EIS Engineer owns the technical infrastructure that connects those functions and ensures information moves between systems accurately and reliably.
You will be the technical partner teams turn to when a new workflow needs to be integrated, a process requires automation, or an issue spans multiple systems. You will not own every business process, but you will own the infrastructure that enables those processes to work together.
This is a hybrid role with an expectation of working onsite three days per week.
Your Responsibilities (What You Will Own): : Digital Tool Assessment & Implementation
- When a new digital tool is needed, assess what's available in the existing ecosystem and make the final selection call in coordination with Engineering
- Configure new tools at the system level — modules, licensing, permissions, and integrations — so domain teams can build on top of them
- Own the technical infrastructure underneath what engineers build; if the plumbing is broken, you get the call
Integration & Automation Infrastructure
- Maintain and develop all integrations between systems including but not limited to Manufacturo (MFO), NetSuite, and Mangrove
- Own automation scripts running in Manufacturo's Integrator module (C#)
- Ensure NetSuite ↔ MFO integration flows are error-free and assembly builds are triggering correctly
- Manage the data pipeline from MES to MRV reporting tools (SQL queries, Google Sheets connection)
- Build new integrations as the business introduces new processes or systems
- Own UAT test plans for new integrations; coordinate domain owners to test their respective pieces
- Ensure data is protected and security best practices are followed
- Create diagrams, wikis and system records to clearly document your designs.
Cross-System Anomaly Resolution
- Intake, triage, and prioritize data anomaly tickets that cross system boundaries
- Investigate root cause, coordinate with the relevant domain owner, and own the fix at the integration or infrastructure layer
- Document root causes and resolutions to reduce repeat issues
Data & Reporting Infrastructure
- Write and maintain SQL queries that feed MRV and operational reporting
- Update queries and scripts when processes change
- Fulfill data requests from internal stakeholders — dashboards, CSVs, live data connections — in coordination with the relevant domain team
System Administration
- Administer Manufacturo, NetSuite, and Mangrove at the configuration level: items, products, user roles, licenses
- Maintain hardware peripherals connected to these systems — label printers, scanners, tablets, and the Bartender integration
- Own the master documentation library; ensure domain teams are documenting their own processes
NPI / Process Change Support
- When Engineering introduces a new process, configure the technical infrastructure to support it: data collection fields, automation scripts, and integration outputs
- Consult with Engineering and Ops Process Specialists during process builds to ensure the system can support what they're designing
- Support integration testing and go-live; Responsible Engineer owns approval
What You Won't Own
To set expectations clearly: this role does not own process design, work order construction, or data collection field definitions (Engineering Process Specialist); shop floor execution quality or operator training (Operations Process Specialist); MRV data requirements or Mangrove data quality (MRV team); or NetSuite financial data quality (Finance/Controller). Those teams own their domains. You are their systems infrastructure partner, not their data steward. When a process plan is wrong, they get the call. When the plumbing is broken, you do. You Bring: • 2+ years in a systems integration, MES/ERP administration, or manufacturing IT role
- Hands-on experience with an ERP system — NetSuite strongly preferred
- SQL proficiency: writing, maintaining, and quality-checking queries against relational data models
- Familiarity with API integrations and middleware concepts
- Basic scripting ability in C# or a comparable language; comfort using AI tools to accelerate development and debugging
- Strong communication skills — you'll be coordinating across Engineering, Operations, MRV, and Finance regularly
- Strong Understanding of Information Security best practices.
Other Preferred
- Experience with Manufacturo or a comparable MES platform
- Experience with Mangrove or similar environmental data / MRV platforms
- Familiarity with Ignition SCADA or industrial data systems
- Experience managing third-party integration vendors or consultants
- Background in manufacturing, biorefining, chemical processing, or a similarly data-intensive industrial environment
- Networking fundamentals helpful for hardware troubleshooting
Characteristics that matter
- You take ownership of the infrastructure, not just the tickets. When the plumbing is broken, you find it before someone else does.
- You're comfortable operating across team boundaries without formal authority — this role succeeds through relationships and trust, not control.
- You document as you go. Institutional knowledge that lives only in your head is a liability, and you know it.
- You understand that your job is to make domain owners successful, not to be the smartest person in the room on every topic.
- Love what you do, and be self driven to be great at it. Bonus, if you Bring: • Experience using Claude AI Coding Assistant
- Security certifications like Security+, ISC2
- Experience working with Google Cloud Platform Infrastructure
- Experience with GitHub and development pipeline practices
