Backend Engineer (Golang)

About the team

You will join Equativ’s core engineering team in Berlin, where we design, build, and operate 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 that serve millions of viewers and requests per second on regular TV streaming and during high-profile live events, including the Soccer World Cup on Magenta TV.

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

What you will do

Software development is the central focus of this role. You will design and implement high-performance Golang services that operate under strict latency and throughput requirements. You will work on both functional product features and non-functional aspects such as performance optimization, scalability, and system stability.

You will regularly analyze production behavior, improve algorithms based on real traffic patterns, and apply best-of-breed technologies where they make sense. Because our systems operate at a scale that standard tooling does not always cover, you will also contribute to the development of custom debugging, monitoring, and observability tools tailored to our platform.

You are expected to communicate clearly and proactively, participate in architectural discussions, contribute thoughtfully to code and merge reviews, and maintain high standards for clean, maintainable code.

Responsibilities

As a backend engineer at Equativ, you will take responsibility for designing and delivering backend features end-to-end. You will write well-structured, readable, and testable code, and you will ensure that the services you build can be reliably operated in production. You will organize your work independently, communicate progress and challenges transparently, and continuously develop your technical skills with the goal of taking on increasing responsibility over time.

• You have at least two years of professional experience building backend systems in Golang
• You are comfortable working with key-value stores such as Aerospike or Redis and have experience using Kafka or similar data streaming platforms
• You understand the fundamentals of distributed systems and performance-critical backend architectures, and experience with high-throughput or real-time systems is a strong plus.
• Familiarity with video streaming technologies is welcome but not required
• You have operational experience with modern infrastructure and deployment tooling, including Docker, Kubernetes, GitLab CI/CD, and infrastructure-as-code tools such as Terraform and Helm

• Hybrid work model with the option to work remotely up to 50 percent of the time
• Urban Sports Club membership
• Fully paid Deutschlandticket for public transportation, and access to a modern office in the heart of Berlin
• The team regularly organizes social events and hackathons, and we have a budget for conferences, courses, and professional development
