Mid Level Golang Engineer

This is Go engineering where it counts. You will build the backend services that process runtime data from eBPF sensors and cloud APIs at serious scale, turning raw signals into clear, prioritised risk for some of the most demanding cloud environments in the world. You will own your services end to end, from design through deployment and monitoring, in a low-ego, engineering-led team where ideas win on merit. If you love Go, care about performance and want your code to stop real attacks, this is where you belong., * Design and build high-throughput backend services in Go

• Process runtime data from eBPF sensors and cloud provider APIs at scale
• Own services end to end, from design and deployment to monitoring and maintenance
• Build and run services on Kubernetes across AWS, GCP and Azure
• Reason about cost, scalability and trade-offs in every design
• Work with Redis, Elasticsearch, Neo4j, RabbitMQ and TimescaleDB
• Collaborate with Research and Security teams to turn new attack techniques into product
• Contribute to design and code reviews that raise the bar for the team

• 3+ years’ commercial backend engineering experience
• Strong production experience in Go
• Experience building distributed, event-driven or high-throughput systems
• Hands-on experience with Docker, Kubernetes and at least one major cloud platform (AWS, GCP or Azure)
• Solid Linux fundamentals
• Based in Northern Ireland with existing right to work in the UK (visa sponsorship is not available)

Desirable / Nice to Have:

• Experience with eBPF, Linux internals or low-level networking
• A background in or genuine interest in cybersecurity
• Side projects or technical interests beyond your day job

• Competitive salary, dependent on experience
• Stock options, giving you a real share in the company’s growth
• Hybrid working in Belfast City Centre, state of the art offices
• Write Go on one of the most technically ambitious platforms in cloud security
• Work with eBPF and runtime technology most engineers only read about
• Backed by more than $800 million in funding, giving you the runway to build boldly
• Join a fast-growing Belfast hub where mid-level engineers are mentored by strong senior talent

Every second, this company’s eBPF sensors are watching live cloud workloads and turning that runtime data into the risks that truly matter. Its platform covers everything from misconfigurations and API security to real-time threat and malware protection, and it is quickly becoming one of the most talked-about names in cloud security. Founded in 2022 by a team who had already built and sold a cloud infrastructure business, it closed a $400 million Series C in October 2026, just nine months after a $250 million Series B, taking total funding past $800 million at a reported valuation of $3.8 billion. It now has 600+ people, 400+ customers and a Belfast engineering hub that is growing so fast it keeps taking on more office space.
