Title: Linux Systems Engineer

Location: London (Remote)

Company Overview:

We are Europe’s largest commercial broadcast radio and digital audio company, leading the industry across nine markets, including the UK. Our innovative approach ensures we remain at the forefront of audio advertising, delivering high-quality content and pioneering solutions to millions of listeners. Our mission is to engage audiences with compelling audio experiences, driven by data and innovation.

Our Team:

SharpStream is part of Bauer Media Audio, Europe’s leading digital commercial radio broadcaster and audio operator. Our team focuses on providing a market-leading intelligent distribution network that enables our clients to stream live and on-demand audio content. We’re a future-oriented, fast-paced team using cutting-edge technology to deliver solutions, and we believe in fostering a collaborative culture with opportunities for learning, conferences, and supplier site visits.

The Role:

As we expand our team of 10, we’re looking for an 11th member to join us as a Linux Systems Specialist . You will play a critical role in ensuring the high availability and performance of Sharp-Stream’s audio streaming platform by designing, maintaining, and optimising our Linux-based infrastructure. This includes modernising systems into a container environment, automating processes to help maintain our 99.995% SLA, and managing high-visibility, production-critical systems. This role offers significant autonomy, with the freedom to innovate within a smaller, tightly knit team, and provides exposure to a wide variety of technologies and clients in the audio space

Key Responsibilities:

  • Design and implement scalable Linux systems using infrastructure as code (primarily Ansible), with a focus on modernising services into container environments (Docker, moving towards Kubernetes).
  • Troubleshoot and resolve service failures, focusing on network-related issues in the streaming environment.
  • Optimise TCP/IP stack performance and enhance system security.
  • Work on improving bandwidth and firewalls, especially for international points of presence in the EU.
  • Support the architecture and planning of our infrastructure and work closely with vendors.
  • Participate in a rotating on-call support system (every 4th week), ensuring 24/7 operational coverage for critical outages.
  • Collaborate with internal teams to continuously enhance the platform, supporting client visits and vendor relationships as necessary.

What We’re Looking For:

Non-Negotiable Skills:

  • Linux Systems Administration: Solid foundation in Linux (preferably Debian) administration.
  • Networking Expertise: Proficiency in TCP/IP, DNS management, and troubleshooting network issues. Experience with BGP/OSPF and Juniper technologies is highly desirable.
  • Infrastructure as Code: Expertise in Ansible and experience working in hybrid cloud environments (AWS, GCP, or similar).
  • Web Technologies: Experience with Nginx, Apache, and content caching.
  • Containerisation: Experience with Docker, and knowledge of Kubernetes is a plus.
  • Database Management: Familiarity with MySQL or Galera is advantageous.

Desirable Skills:

  • Familiarity with streaming technologies such as HLS, Shoutcast, and Icecast.
  • Experience with firewalling and multi-site network management.
  • Coding or scripting experience in Bash, PHP, or Python for automation and troubleshooting.
  • Willingness to travel to EU sites to support system architecture and vendor communications.

Key Personality Traits:

  • Naturally Curious: You thrive on exploring new technologies and finding creative solutions to complex problems.
  • Attention to Detail: A meticulous approach to troubleshooting and resolving issues.
  • Calm Under Pressure: You can manage high-visibility production systems with a calm, logical approach.
  • Excellent Communicator: You can explain technical details to both technical and non-technical stakeholders effectively.

Why SharpStream?

  • Exposure to cutting-edge technologies and the chance to modernize critical infrastructure.
  • Smaller team structure, giving you significant responsibility and freedom to innovate.
  • Collaborative, fast-paced environment where technical curiosity is valued.
  • Competitive salary and additional remuneration for on-call support.
  • Fully remote with opportunities for client visits and vendor site interactions.

Hiring Process:

  1. HR Screening Call: General overview and initial alignment.
  2. Technical Interview: Focus on crisis management and technical expertise
  3. Management Interview: Final stage interview to cover off final questions and assessment for culture fit
