Software Engineer (Java Generalist)

Location: US - Open to Europe if happy to overlap with EST

Compensation: $160K - $200K

Our firm has been retained by a high-growth, mission-driven technology company to find a world-class Principal Java Systems Engineer. This is not a role for "glue" engineers who connect off-the-shelf components; this is for the engineer who sees performance ceilings as a personal challenge and prefers squeezing 30% more throughput out of clean Java over renting 30% more cloud compute.

Our client is building a high-performance, publicly visible immutable ledger. In an industry where people "move fast and break things," this team operates like NASA: moving fast while ensuring correctness, performance, and efficiency are 100% right the first time. You will join an elite team where you aren't a cog in the machine—you are the architect building it.
