Integration Engineer

Molecule Software | Poland (Office)

Molecule is a modern ETRM platform built for energy trading companies across power, natural gas, renewables, and financial commodities. We’re growing our integration capability and looking for an Integration Engineer to own the technical connectivity that sits at the heart of every client implementation.

The role

You’ll design, build, and maintain the integrations that connect Molecule to the systems our clients depend on — market data providers, exchange platforms, generation data sources, ERP and CRM systems, SCADA historians, and downstream analytics infrastructure. You’ll also build custom reports in SQL, turning client data into the insights they need.

This is an end-to-end ownership role: from integration design through to testing, documentation, and handover. Where your profile supports it, you’ll engage directly with client technical teams — representing Molecule in integration design discussions and supporting go-live.

What you’ll work on

• Building integrations with ISO and market data providers (Montel, Pharos, ZEMA), exchange platforms (ICE, CME, Nodal), ERP/CRM systems (SAP, Microsoft), and generation data sources

• API-based price extraction — forward curves, LMPs, ancillary service prices, settlement data

• Outbound data feeds and BigBang data lake integration for positions, P&L, and valuations

• REST APIs, SFTP/FTP, webhooks, and email-based automation

• SSO and MFA configuration

• Custom report development in Mode using SQL

What we’re looking for

• Background in energy, commodities, or financial services — familiarity with ETRM/CTRM workflows is strongly preferred

• Strong Python and TypeScript — both used daily

• Solid SQL for data transformation, validation, and reconciliation

• Hands-on experience with real-world integrations: market data vendors, exchanges, ERP/CRM, or SCADA systems

• Good understanding of REST APIs, OAuth 2.0, SAML, and common data formats (JSON, XML, CSV, FIX)
