I’m currently partnered with one of Europe’s leading video streaming platforms, delivering a range of B2C & B2B solutions.
As they continue scaling, they’re looking for a Principal Engineer to shape the architecture behind both their streaming infrastructure and advanced advertising technology platform.
This role sits at the intersection of high-performance video delivery and revenue-generating ad technology, where milliseconds matter for viewer experience and architecture decisions directly impact monetisation.
The Opportunity
As a Principal Engineer, you’ll define the technical vision for systems operating at massive scale-building low-latency streaming pipelines, intelligent ad insertion platforms, and highly resilient distributed systems.
You’ll work across teams to design platforms that optimise viewer engagement, streaming performance, and advertiser ROI in real time, while mentoring senior engineers and driving technical excellence across the organisation.
The Role
-
Driving technical strategy and architectural direction across streaming and ad technology platforms
-
Designing and evolving large-scale distributed systems serving millions of concurrent viewers
-
Architecting streaming infrastructure including adaptive bitrate pipelines and CDN optimisation
-
Contributing to a sophisticated advertising technology platform, including dynamic ad insertion (DAI/SSAI)
-
Building low-latency streaming and ad delivery pipelines
-
Ensuring operational excellence, reliability, and performance at scale
-
Leading cross-functional collaboration between engineering, product, and platform teams
-
Mentoring senior engineers and helping shape engineering standards and technical culture
-
Promoting knowledge sharing and building strong engineering practices across teams
-
Translating business and monetisation goals into scalable technical solutions
Your Background
-
8+ years of experience building large-scale distributed backend systems
-
Expert programming skills in C++ and/or Go, particularly for high-performance backend services
-
Strong experience building systems that support massive concurrency and high-throughput streaming workloads
-
Deep understanding of video streaming technologies including:
-
HLS / DASH protocols
-
Content Delivery Networks (CDNs)
-
-
Strong experience with advertising technology platforms, including ad serving and dynamic ad insertion (DAI/SSAI)
- Strong understanding of global content delivery, edge computing, and CDN optimisation strategies
-
Proven experience mentoring senior engineers and influencing technical decisions across multiple teams
Why This Role Stands Out
-
Architect platforms powering millions of global viewers
-
Work at the intersection of video streaming and advertising technology
-
Solve complex distributed systems problems at scale
-
Join a company going through significant growth and backend investment
-
High-impact principal-level role with influence across multiple engineering teams
