Senior Software Engineer

Acheron is a market maker holding a CASP license issued by the AFM in the Netherlands under MiCAr and with passporting in all EU countries.

Acheron provides liquidity services to digital asset issuers from their most embryonic stages and throughout their adoption cycle. It is our belief that market inefficiency is one of the factors preventing digital assets from achieving mass adoption.

• Build High-Volume Financial Systems: Design, develop, and maintain our real-time trade ledger and financial reporting systems, ensuring absolute data accuracy and integrity while processing thousands of transactions per second.
• Automate Large-Scale Reconciliation: Build and enhance automated trade reconciliation systems to compare and match vast datasets from our internal records against exchanges and custodians.
• Enhance Security: Implement and uphold robust security measures across all financial systems, including access controls and data protection protocols.
• Develop Internal Tooling: Create and maintain internal dashboards and tools (using React/Angular and Node.js) for our finance, compliance, and trading operations teams.
• Collaborate and Own: Work closely with our finance and operations teams to translate their requirements into resilient technical solutions and take ownership of the full development lifecycle.
