Position Overview:

We are seeking a Senior Scrum Master & Jira Admin to lead Agile delivery while owning and continuously improving our Jira ecosystem. This role requires strong system thinking, delivery discipline, and the ability to influence both teams and leadership.

Senior Staff Backend Engineer

Location: Manhattan, New York

Onsite | Full-time

We are hiring on behalf of our client who is the development powerhouse behind one of the largest and most high-traffic platforms in the digital asset space. Currently processing ~$1B in daily volume, their technology stack handles low-latency, high-throughput, and constant load at a scale few companies ever reach.

The Role

In this role, you will act as a technical anchor, overseeing the integrity and evolution of their core backend systems. You will balance high-level architectural governance with deep-tier execution, driving technical excellence from the front. Your primary focus will be the proactive mitigation of scaling risks and the design of durable, fault-tolerant systems capable of sustaining high-throughput workloads.

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.
