Role overview
Computer and Network Security24 employees
Tracebit generates and maintains tailored canary resources in your cloud environments, closing gaps in stock protection without time and cost intensive detection engineering.
What you will do
- Build and scale a cloud-native security product using C# on .NET Core 10, Terraform, and HTMX within an AWS environment.
- Collaborate face-to-face with technical founders and high-profile customers to translate security research into robust, production-ready detection features.
- Take ownership of end-to-end delivery in a low-bureaucracy environment, shipping code daily and maintaining infrastructure as code for planetary-scale event processing.
Who this is a fit for
- Proven track record of shipping software at scale or in critical environments, ideally within a product-focused company or high-growth startup.
- Strong proficiency in any object-oriented language; while we use C#, we value architectural instinct and engineering quality over specific language syntax.
- A proactive builder who thrives in an on-site, collaborative culture and is excited by the pace of an early-stage company defining a new security category.
Why this role is remarkable
- Join one of the UK's most exciting startups, recently raising a $20M Series A led by FirstMark and featured on Sifted's 2025 "London Startups To Watch."
- Experience explosive growth with a company that doubled ARR last quarter and plans to triple its headcount over the next year.
- High-impact work environment where you will solve real-world problems, such as uncovering P1 security flaws in major AI platforms like Google Gemini.
