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.

Requirements:
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
Architecture at system scale: throughput, distributed coordination, performance trade-offs
Design review leadership: you can take apart a design constructively and propose one that will hold
A track record of mentoring engineers who got better because of you
You treat code quality as a system property, building the standards and culture that sustain it
Strong Plus:
Spring experience
gRPC-based communication
Python programming
Experience in polyglot environments
AI coding agent experience, with opinions on how a team should use them well
Experience with real-time, low-latency, or hardware-adjacent systems
You'll Thrive Here If You:
Lead through reasoning, not title
Ask questions when requirements are unclear, rather than guessing
Know when to insist on "right" vs. "good enough to ship"
Give direct, kind feedback
Communicate clearly, including to non-backend audiences.
