About The Role
We are hiring a Senior Backend Engineer to work on some of the most interesting problems in cybersecurity — building the platform that connects 150+ security tools, serves enterprise customers at scale, and now powers a new generation of AI capabilities. You will work in C#/.NET on AWS, report to the Head of Engineering, and be surrounded by people who care deeply about what they build. If you are an exceptional engineer who wants to do the best work of your career, this is the role.
Why ThreatAware?
ThreatAware gives security teams a single source of truth for every device and tool in their organisation. 150+ integrations, deploys in under 30 minutes, real-time visibility across entire IT estates. Finance, legal, energy, healthcare — they trust us to show them what is protected and what isn’t. Now we are building something bigger. Six years of accurate cyber asset data, and we are layering AI on top of it — new ways for security teams to interrogate their data, automate workflows, and act on risk before it becomes a problem. The platform you work on is the foundation everything else sits on.
What you will do
- Help design and evolve the core architecture: integration framework, APIs, data models, and the multi-tenant infrastructure that scales for enterprise.
- Build the backend services that power our AI capabilities — the APIs and data pipelines that feed LLMs with accurate, real-time asset data.
- Work across the integration platform that connects to 150+ security tools — designing patterns that make new integrations fast, reliable, and elegant.
- Tackle genuinely complex engineering challenges: event correlation across time, high-throughput data pipelines, and APIs that need to be both fast and secure.
- Security is at the heart of everything we do — and everything you will build.
- Mentor other engineers. Code reviews, design reviews, architectural thinking — help raise the standard for the whole team.
What we are looking for
- An excellent engineer. Deep C#/.NET expertise, strong system design instincts, and the kind of thinking that makes the people around you better.
- Experience working on multi-tenant SaaS platforms on AWS or equivalent cloud infrastructure.
- Strong API design and database architecture skills.
- You think about scale, reliability, and maintainability by default.
- Curiosity about AI and LLMs. You are excited about building the backend systems that make AI features possible.
- You have mentored engineers and raised technical standards across a team.
- Bonus: experience building integration platforms or connector frameworks.
