The Opportunity:
As a Senior Developer, you’ll have significant autonomy to shape how some of the world’s largest telecom operators communicate with consumers and detect issues across their networks. You’ll help evolve the platform into a proactive, intelligent system built around Observe - Think - Act workflows, designing autonomous, AI‑driven operations that surface insights, trigger actions, and streamline complex network processes at scale.
You’ll work across the full stack, building intuitive interfaces in React and architecting resilient Python backend systems capable of handling massive volumes of time‑series telemetry. You’ll join a dynamic, experienced global product and engineering team, collaborating with specialists across mobile SDKs, cloud platforms, and large‑scale distributed systems, while working directly with global customers.
If you’re excited by the challenge of building intelligent systems, solving complex data problems, and driving meaningful impact at global scale, this role offers the scope and technical depth to do your best work.
Key Responsibilities:
- Full-Stack Development: Develop and maintain robust, scalable web applications using React, Redux, and modern backend frameworks.
- Automation & AI Features: Move the platform from reactive reporting to proactive operations by implementing "Observe-Think-Act" loops for network outage detection and communication.
- Maintain Technical Quality: Write clean, maintainable, and efficient code while conducting high-signal code reviews to elevate engineering standards.
- Collaborate Cross-Functionally: Work closely with Product teams to translate emerging AI capabilities into high-performance features for our global operator clients.
- Scale Data Processing: Help maintain and optimize backend services capable of handling high-volume network telemetry and time-series data.
