Senior Software Engineer

About Us

Bauer Media reaches millions of people across Europe through audio, digital, and out of home advertising. Within Bauer Media Outdoor we operate thousands of digital screens and poster sites in high impact locations.

We are modernising the platforms that power how brands buy, manage, and measure outdoor advertising. Our teams are building scalable advertising and data platforms that support programmatic buying, self service tools, and data driven campaign optimisation.

Our mission is simple.

Create tech that makes a difference. Empower teams. Delight customers. Shape the media world of tomorrow.

The Role

We are looking for a Senior Software Engineer with a strong focus on the foundational qualities of high-performing systems: reliability, scalability, performance, and engineering excellence.

This is not a support or operational role. It is a hands-on senior engineering position focused on shaping how systems are designed, built, and operated at scale.

You will work on revenue-critical platforms that power campaign planning, audience targeting, real-time bidding, inventory management, and campaign performance analytics across Europe. Your work will directly influence how reliably and efficiently these systems operate under real production load.

You will act as a technical reference point for non-functional excellence, helping teams design systems that scale confidently as our traffic, markets, and data volumes grow.

What You Will Work On

• Distributed services supporting real-time bidding and campaign execution
• High-throughput APIs and data pipelines
• Platform-level reliability, performance, and observability
• Architectural improvements that reduce operational risk and increase resilience
• Engineering standards that enable teams to move fast without compromising quality

What You Will Do

Engineer Systems for Scale and Resilience

• Design and evolve services that are resilient, observable, and capable of operating at significant scale
• Embed reliability, performance, security, and cost efficiency into architectural decisions from the outset
• Define and evolve service-level objectives (SLOs) and reliability standards
• Lead capacity planning, performance testing, and scalability initiatives
• Improve fault tolerance through better system design and failure modelling

Improve Performance and Operational Excellence

• Identify performance bottlenecks across services, APIs, and data pipelines
• Optimise application code, queries, and service interactions to improve latency and throughput
• Strengthen observability through improved monitoring, logging, and instrumentation
• Reduce production incidents by improving resilience and early detection mechanisms

Raise Engineering Standards

• Promote high-quality engineering practices including clean code, automated testing, and CI/CD
• Drive consistency in reliability and performance practices across multiple teams
• Contribute to design reviews with a strong focus on long-term maintainability and system health
• Introduce measurable quality and reliability metrics and help teams use them effectively

Influence Technical Direction

• Collaborate with engineers, architects, and product teams to ensure systems are designed for scale and reliability
• Provide technical guidance on complex engineering trade-offs
• Mentor engineers and contribute to a culture of engineering excellence
• Help shape the long-term technical direction of our advertising platforms

What You Will Bring

• Strong experience building and operating production-grade software systems
• Experience designing distributed systems and cloud-based architectures
• Demonstrated ability to improve system performance, scalability, and reliability
• Deep understanding of non-functional requirements and how they influence architecture
• Experience working with observability, monitoring, and performance analysis tools
• Experience contributing to or establishing engineering standards across teams
• Strong coding ability and a pragmatic approach to improving existing systems
• Clear communication skills and the ability to influence across teams

Experience with high-throughput systems, event-driven architectures, or real-time platforms is highly valued.

How Success Is Measured

Success in this role is reflected through measurable improvements in the reliability, performance, and quality of our platforms, including:

• Platform services operating reliably under increasing production load
• Clear service-level objectives defined and adopted across teams
• Measurable improvements in system performance and efficiency
• Reduction in production incidents and improved fault tolerance
• Reduced time to detect and resolve production issues
• Higher-quality, more maintainable codebases
• Systems that scale effectively as traffic, data volumes, and markets grow

Why This Role Is Impactful

• You will shape the reliability and scalability of platforms used across multiple European markets
• Your work will directly influence revenue-critical systems
• You will solve complex distributed systems challenges at real-world scale
• You will help engineering teams move faster by strengthening the foundations they build on
• You will play a key role in defining what engineering excellence looks like within Bauer Media Outdoor
