Enterprise Information Systems Engineer

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 such as Stripe, Shopify, and Microsoft. Since then we have 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.

Charm is hiring an Enterprise Integration Systems (EIS) Engineer to own the technical infrastructure connecting our core operating systems, including Manufacturo (MFO), Net Suite, 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.

• 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

• Maintain and develop all integrations between systems including but not limited to Manufacturo (MFO), Net Suite, and Mangrove
• Own automation scripts running in Manufacturo’s Integrator module (C#)
• Ensure Net Suite 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.

• 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

• 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

• Administer Manufacturo, Net Suite, 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…
