Quantum Machines is a global leader in control systems for quantum computing, scaling from individual qubits to arrays of thousands.
We're looking for a hands-on Tech Lead to drive the technical direction of our core backend layer and lead the engineers building it. The systems you'll own handle bursty, high-throughput workloads: thousands of requests per second, strict latency requirements, distributed coordination, hard concurrency problems. You'll shape the architecture, review the designs, and still write the code.
What Makes This Role Different
Our backend team is the orchestration layer between:
Hardware control systems (C++)
Client-exposed SDK (Python)
Reporting and management system (Go)
Business logic (Java/Kotlin + Spring)
As Tech Lead, you're the technical anchor of that layer. When teams disagree on where a boundary belongs, you drive the decision. When a design has a flaw nobody's spotted, you catch it. When the hardest problem lands, you're close enough to the code to pick it up yourself.
דרישות
8+ years building backend systems in Java/Kotlin, including experience leading the technical work of a team
You still write code, and you're good at it - this is not a management-only role
Deep concurrency expertise: race conditions, lock ordering, async patterns - and you can teach others to reason about them
