Description
Join Cisco's Webex Media engineering site in Stockholm, where we craft the meeting experience that connects people and businesses around the world.
You will design, implement, and optimize VoIP audio algorithms,including adaptive jitter buffers, packet loss concealment, and codec pipelines,based on product requirements.
Key responsibilities:
- Perform peer code reviews and automate development workflows and quality gates.
- Participate in agile ceremonies including daily stand-ups, planning, releases, and retrospectives.
- Collaborate across teams to broaden technical and soft skills through training and mentoring.
Requirements:
- 7+ years of professional software development experience and a MSc (or equivalent) in Software Engineering or a related field.
- Hands-on experience developing VoIP or real-time audio algorithms (e.g., adaptive jitter buffer, packet loss concealment, codec integration) in production systems.
- Proficiency in C/C++ with strong knowledge of data structures, algorithms, and design patterns.
- Experience with media streaming and relevant protocols for real-time applications.
- Professional verbal and written communication skills in English.
Nice to have:
- Experience applying AI/ML to audio algorithm development or optimization in production voice systems.
- Experience evaluating and tuning audio algorithms using objective metrics (e.g., POLQA, PESQ) and subjective listening tests.
- Experience with close-to-real-time systems and performance-sensitive code paths.
- Comfort with incremental development, testing, and A/B testing in production.
