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!

Charm is hiring an EIS (Enterprise Integration Systems) Engineer to own the technical infrastructure connecting our core operating systems:
Manufacturo (MFO), Net Suite, and Mangrove, among others. This role operates within the IT organization and is responsible for the plumbing — integrations, automation scripts, system administration, and cross‑system data anomaly resolution.

Charm operates a federated ownership model. Engineering, Operations, MRV, and Finance own their respective data and processes. The EIS Engineer owns the infrastructure underneath them. You are the person those teams rely on when data needs to flow between systems reliably, when a new process needs to be wired up technically, or when something breaks across a system boundary. You are not the owner of every problem — but you are the owner of the infrastructure that causes them.

• 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 the master documentation library; ensure domain teams are documenting their own processes.

• When Engineering introduces a new process, configure the technical infrastructure to support it: data collection fields, automation scripts, and integration outputs.
