Backend Engineer (Golang)

About the Role

You will join Equativ’s core engineering team in Berlin, designing, building, and operating massively scalable real-time advertising systems. This is a pure backend engineering role with a strong focus on Golang. Your work will directly impact production systems serving millions of viewers and requests per second on regular TV streaming and high-profile live events, including the Soccer World Cup on Magenta TV.

The team specializes in server-side ad insertion for real-time video streaming, tackling complex problems around latency, scalability, and reliability at very large scale. Engineers are deeply involved in technical decisions and take full ownership of the systems they build.

What You Will Do

• Design and implement high-performance Golang services with strict latency and throughput requirements
• Work on functional product features as well as non-functional aspects such as performance optimization, scalability, and system stability
• Analyze production behavior and improve algorithms based on real traffic patterns
• Contribute to the development of custom debugging, monitoring, and observability tools for large-scale systems
• Participate in architectural discussions, code reviews, and maintain high standards for clean, maintainable code

Responsibilities

• Design and deliver backend features end-to-end
• Write well-structured, readable, and testable code
• Ensure services can be reliably operated in production
• Organize work independently, communicate progress and challenges transparently
• Continuously develop technical skills with a goal of increasing responsibility over time

About You

• At least 2 years of professional experience building backend systems in Golang
• Experience with key-value stores such as Aerospike or Redis, and streaming platforms like Kafka
• Strong understanding of distributed systems and performance-critical backend architectures; experience with high-throughput or real-time systems is a plus
• Familiarity with video streaming technologies is welcome but not required
• Operational experience with modern infrastructure and deployment tooling, including Docker, Kubernetes, GitLab CI/CD, Terraform, and Helm

Perks and Benefits

• Hybrid work model with up to 50% remote work
• Urban Sports Club membership
• Fully paid Deutschlandticket for public transportation
• Access to a modern office in the heart of Berlin
• Social events, hackathons, and a professional development budget for conferences and courses
