Hello, let us introduce ourselves!

watchTowr is the Preemptive Exposure Management capability trusted by Fortune 500 companies and critical infrastructure providers.

By combining proactive threat intelligence, real attacker telemetry, and automated red teaming, watchTowr continuously identifies and validates real exposure - so security teams can outrun real-world threats.

When exploitation happens in hours, watchTowr delivers what no one else can: time to respond.

We are a global team of operators, researchers, and engineers who have spent years thinking like attackers - and we are now building the technology to stop them. Our work is recognised across the industry, with original vulnerability research from watchTowr Labs and innovations like Instinct and Attacker Eye shaping the future of cybersecurity.

Backed by $29M in funding, recognised by Gartner, and scaling fast across the globe, we are in a high-growth phase of our journey. We are a young, high-energy, and research-driven team, obsessed with building world-class technology - and we want exceptional people to join us.

But what’s the role?

We’re looking for a Senior Backend Engineer with a strong foundation in backend architecture and data infrastructure to help us build and scale the core systems that power our offensive security platform.

You'll be part of a high-impact team working to help some of the world’s largest enterprises understand their real-time security exposure. Your work will directly shape how our platform ingests, processes, and serves critical vulnerability data at scale.

Sounds great – what will I do?

• Design, build, and maintain backend services and data pipelines that support our backend system which powers our cybersecurity platform - the platform we use to identify vulnerabilities in large enterprises
• Architect scalable microservices and APIs to handle large volumes of data relating to millions of assets belonging to our clients and how they can be compromised
• Work closely with frontend engineers and product teams to integrate backend systems with the user interface and reporting layers
• Continuously improve our systems, from deployment to monitoring, as we scale rapidly.

Sounds perfect to me, what specifics are you looking for?

Technologies

• Demonstrated ability to thrive in fast-paced startup environments, showing a strong sense of ownership and initiative
• A can-do attitude with the willingness to take on ambiguous challenges, wear multiple hats, and drive projects forward independently

Bonus Experience

It’ll also be awesome if you:

• Experience working with large-scale data processing or streaming systems, especially for security analysis
• Familiarity with data engineering tasks like building ETL pipelines and schema versioning
• Exposure to DevOps practices and CI/CD tooling for automated deployment and monitoring
• Familiarity in Cloud-based services & able to leverage Cloud-based services as part of service deployments
• Prior work in an Agile, DevOps-driven engineering culture.

What’s in it for me?
