Job description

Hybrid Roles 2-3 days in the Belfast office | Cloud Security | Northern Ireland

Ocho is proud to be working in partnership with a high-growth cloud security company that established its Northern Ireland engineering hub just over two years ago. Since launching locally, the team has grown to 40 engineers and is now entering a major scale-up phase following a $250 million investment earlier in the year.

As part of ambitious growth plans through 2026 and beyond, we're hiring multiple Tech Leads (Golang / Java) to join their expanding backend engineering group.

The Opportunity

In this role, you'll work on technically complex, real-world problems every day building new, innovative capabilities while continuously improving and scaling existing systems.

You'll operate in a modern, cloud-native environment and have genuine ownership over what you deliver, from early architectural design through to deployment, monitoring, and long-term optimisation in production.

The platform integrates deeply with AWS, GCP, and Azure, and makes heavy use of technologies

such as:

• Golang
• Java
• Docker
• eBPF
• Distributed systems at scale

This is not a "ticket factory" role it's an engineering-first environment where you'll solve meaningful problems that directly impact global customers.

The Role

As a Backend Software Engineer, you'll:

• Own services end to end: design, build, deploy, monitor, and iterate
• Contribute to technical and architectural decisions
• Perform reliability and performance analysis on Golang / Java-based systems
• Conduct high-quality design and code reviews
• Work closely with Product, Frontend, and DevOps teams to deliver best-in-class features
• Contribute to capacity planning and SLO definition
• Continuously improve scalability, performance, and reliability

You'll be building and enhancing data-intensive systems that operate in highly dynamic production environments.

About the Company

This is a modern cloud security startup operating at runtime to protect customer infrastructure using deep system visibility and contextual data.

Unlike traditional tools, the platform leverages runtime insights and eBPF-powered sensors to identify and prioritise real risks enabling customers to detect threats, reduce risk exposure, and respond automatically at scale.

Despite being under three years old locally, the business is already:

• Well-funded
• Commercially proven
• Scaling globally
• Backed by serious investment

It's a rare opportunity to join early - but with strong financial backing and clear product-market fit.

You'll work with a genuinely modern stack, including:

Core: Golang, Java

What We're Looking For

• Degree in Computer Science, Software Engineering, or similar

• Experience building data-intensive or distributed systems
• Experience with CI/CD pipelines
• Familiarity with microservices architectures
• Strong analytical thinking and ownership mindset

What It's Like to Work Here

This is a high-trust, collaborative engineering culture. The Site Lead describes the team "like a band - everyone plays their part."

You'll work alongside some of the strongest engineers in the local market, in an environment where:

• Engineers own problems, not just tasks
• Technical excellence is valued
• People genuinely enjoy what they do
• There's ambition - but also balance

Salary & Package

• Base salary up to £135k,Equity,Private healthcare,Flexible / hybrid working

This is a chance to make a real impact during a period of record growth, while working on meaningful, technically challenging problems in one of the most exciting areas of modern software engineering.
