Senior Software Engineer (Golang) (Remote then Relocation to Stockholm)

We are currently partnering with an ambitious technology company that is building a next-generation prediction market platform designed as exchange infrastructure rather than a traditional betting product. The business is backed by financially strong shareholders who are investing heavily in both the product and the team, creating a rare opportunity to build without the typical funding constraints of a startup.

The platform is being developed from the ground up and will support:

• Central Limit Order Books (CLOB)

• Real-time market data streaming

• Internal and external market makers

• Institutional-grade APIs

• High-throughput event processing

• Financial settlement and ledger systems

• Operator integrations across multiple jurisdictions

This is a unique opportunity to join at an early stage and play a key role in designing and building the core trading, market, and platform infrastructure alongside a highly experienced engineering team.

The role will initially be remote for the first few weeks to allow for a smooth onboarding process. Following this period, candidates will be expected to relocate to Stockholm and work closely with the team on-site.
