Our company is scaling quickly, and we’re now looking for exceptional engineers particularly those currently based in the US who want to join a fast-growing, venture-backed startup at a pivotal moment in our trajectory.

Our core product enables security teams to detect intrusions inside their cloud infrastructure using decoy canaries lightweight, deceptive assets designed to expose attackers fast and accurately. Demand for this technology is accelerating, and we’re building the team who will define the next generation of cloud defence tools.

Why This Is an Incredible Time to Join

We are at a true inflection point:

  • Recent backing from leading investors, including Accel and Tapestry.
  • Rapid commercial growth ARR doubled last quarter.
  • Customers include globally recognised names like Riot Games, Snyk, Docker, Coveo, Synthesia, and several confidential partners.
  • Featured on multiple “top startups to watch” lists across Europe.
  • Our research recently helped resolve a P1 security vulnerability in Google’s Gemini CLI.
  • The team has grown from 2 to 11 people in just 18 months, with plans to triple again.
  • Our architecture is simple but powerful, enabling us to process billions of weekly events without losing speed or accuracy.
  • If you’re excited by fast iteration, meaningful ownership, and directly impacting customers, you’ll thrive here.

We offer full relocation support, including:

  • £5,000 tax-free relocation payment
  • Help finding accommodation
  • Support with UK setup and logistics (e.g., banking, healthcare registration, etc.)

Who We’re Looking For

We want someone who:

  • Holds high standards for quality but is pragmatic in balancing speed vs. precision.
  • Has several years of experience shipping software at scale, in production.
  • Has worked with at least one public cloud platform (AWS, Azure, GCP).
  • Thrives in a fast-moving environment where priorities evolve quickly.
  • Enjoys building and releasing products directly into the hands of customers.
  • If you don’t meet every requirement but believe you could add real value—we encourage you to apply.

What the Role Involves

  • You’ll report directly to Sam, our CTO and Co-founder, and work side-by-side with an exceptional engineering team.

Your work will include:

  • 1. Building a Product That Solves Real Security Problems
  • Work closely with the founders, engineers, and customers.
  • Shape features based on direct customer feedback and real-world usage.

  • Infrastructure built via Terraform
  • Frontend components developed using HTMX
  • 3. High-Quality Engineering Foundations

We already operate:

  • Continuous delivery
  • Infrastructure as code
  • Simple but scalable architectural patterns
  • Strong internal engineering culture with minimal bureaucracy
  • 4. Every Day Matters

We release frequently, avoid unnecessary process, and build with speed and focus. Expect a hands-on, energetic environment.

Office-First

We work together in our Central London office—right next to Warren Street Station.

Working Rhythm

  • Expect a steady 9am–6pm flow.
    There will be moments where you’ll need to dig in outside standard hours, but we also balance that with flexibility, autonomy, and respect for your time.
  • Visa Support

We sponsor:

  • Skilled Worker Visa
  • Intra-Company Transfer pathways
  • Graduate Visa transitions

What You’ll Gain

This is a rare opportunity to:

  • Join as an early engineer with meaningful ownership.
  • Directly shape one of the most exciting cybersecurity products emerging in the UK.
  • Work in a fast-moving, high-trust, low-bureaucracy environment.
  • Build sophisticated systems processing massive volumes of real-world data.
  • Be part of a startup at the very moment it begins to scale.

Compensation

  • £60,000 – £120,000, depending on seniority and experience.
