PI'm looking for a Senior Python Developer to join a next generation Cyber Security Research start up based in Barcelona b(You do not need Cyber Security experience to apply) /b, who are building mission critical systems that protect national security interests across Europe. There's a once a week on site requirement. /ppbr/ppThey'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. /ppbr/ppNo big data pipelines here, just a pure software engineering focus, the technical environment will be for example: /ppbr/ppbPython Software Engineering, Asyncio/non-blocking I/O, customer RESTful APIs development for polling/monitoring, PostgreSQL, Docker/Kubernetes deployment, and event driven architectures that scale reliably. /b /ppbr/ppIt'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 the international collab. /ppbr/ppWe can pay competitively with great career progression potential as the product takes off. /ppbr/ppWhat they're looking for: /ppbr/pulliSenior level Python engineering expertise (strong async, performance optimization, distributed systems, event driven programming preferred) /liliExperience building scalable backend agents/telemetry/monitoring tools a big advantage, but not essential /liliIf you have front end experience that is desirable, but not essential, also if you have any architectural experience that would also be highly desirable but not essential /li /ulpbr/ppIf this sparks your interest, shoot me an updated CV and I'll jump on a quick call to share more details ASAP. /p
