Company Description

$20M Series A cloud security startup backed by FirstMark and Accel

Job Description

Join a high‑calibre engineering team building the future of cloud intrusion detection. You will develop intelligent canary tripwires that protect massive clients like Riot Games and Docker. Working directly with the founders, you’ll ship daily to process billions of events using a powerful stack of C#, .NET Core, and AWS.

Location

London, UK

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.

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.

The ideal candidate

• 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.
