Product and RoleThey're launching a brand new product line, a critical software that powers real-time monitoring, telemetry collection, and remote execution across distributed servers. You\'ll be the technical anchor, taking this early stage product from prototype to production scale, owning architecture decisions, and building clean, highly optimized Python code that runs efficiently on servers while handling OS-level metrics, remote commands, and robust failure modes.
No big data pipelines here, just a pure software engineering focus, for example:
Asyncio/non-blocking I/O, RESTful APIs for polling/monitoring
PostgreSQL, Docker/Kubernetes deployment
Event-driven architectures that scale reliably
Team and EnvironmentIt's a small, high energy team with real autonomy, where every line of code drives tangible innovation and growth. English fluency is a must for international collaboration.
Qualifications
Senior level Python engineering expertise (strong async, performance optimization, distributed systems)
Experience building scalable backend agents/telemetry/monitoring tools is a big advantage but not essential
Full stack comfort (Python + JS/TS), solid fundamentals, and proactive teamwork
Benefits and How to ApplyIf this sparks your interest, please send an updated CV and I\'ll jump on a quick call to share more details ASAP. We can pay competitively with great career progression potential as the product takes off.
