Founding Engineer(UK Visa Sponsorship)

Job Description

About the Company

Our platform enables security teams to detect cloud intrusions rapidly and reliably using canary-based deception technology—deploying smart, lightweight decoys that alert teams the moment an attacker interacts with them.

We are at a pivotal moment in our growth journey:

• Backed by leading early-stage investors, including Accel and Tapestry.
• Experiencing rapid expansion (doubling ARR last quarter).
• Trusted by well-known organisations such as Riot Games, Docker, Synthesia, Coveo and Snyk, alongside several large confidential clients.
• Featured across multiple industry “top startup” lists, including those from Creandum, Sifted, AlbionVC, Notion, and Accel.
• Our research recently contributed to resolving a critical security vulnerability in Google’s Gemini CLI.
• The team has grown from 2 to 11 people within 18 months, and we expect headcount to triple again as we move into the next phase of scaling.

We operate a streamlined, powerful technical stack capable of processing billions of events per week, built on a mix of familiar industry technologies (AWS, IaC, CD) and some unconventional but highly effective design decisions.

Who We’re Looking For

We’re seeking someone who:

• Is passionate about producing high-quality engineering work and can balance speed with long-term code stability.
• Has experience shipping software at scale or in environments where reliability is critical.
• Ideally brings experience from a product-led company or working with a major cloud provider (AWS, Azure, GCP, etc.).
• Thrives in the fast-changing environment of an ambitious early-stage startup.
• Enjoys getting features into customers’ hands quickly while still having fun building with a small, smart team.
• If you don’t tick every box but believe you bring something unique—we still encourage you to apply.

The Role

You will report directly to Sam, our CTO and Co-Founder, and work closely with the rest of the engineering team (Michael, Niall, Rahul, Dancho and Ed).

What You’ll Do

Collaborate directly with both founders and customers to deliver a product that solves real, high-value security challenges.

Work across the full stack, including:

• C# / .NET 8
• Terraform
• HTMX for frontend development
• Contribute to a mature engineering culture built by technical founders who prioritise strong practices: CI/CD, Infrastructure as Code, simple and scalable architecture.
• Ship code daily, with minimal bureaucracy but high levels of ownership.
• Build features end-to-end, from shaping requirements to deployment.

Work Environment

• We operate from a Central London office next to Warren Street station.
• This is a 5-days-in-office role, designed around high-bandwidth collaboration and rapid iteration.
• Flexibility is offered for unavoidable commitments (family visits, deliveries, travel, etc.), but we aren’t a hybrid or remote-first organisation.
• Working Style & FAQs

How we work

• Daily standups
• Each engineer owns substantial, customer-impacting workstreams
• Collaborative discussions, deep dives, and regular planning cycles
• High autonomy with trust to prioritise effectively
• Hours
• We generally work 9am–6pm, with the expectation that founding engineers occasionally flex outside these hours.

Visa Sponsorship

We are able to sponsor multiple visa types, including:

• Skilled Worker Visa
• Graduate Visa transition
• Intra-Company Transfer (where applicable)
• Compensation
• £60,000 – £120,000, depending on experience.

Why Join Us?

• Work directly with founders on a cutting-edge security product
• Have significant influence on architecture, culture, and engineering standards
• Build in an environment that values simplicity, quality, and rapid iteration
• Join a company on the verge of major growth, backed by top investors
• Help shape one of the UK’s fastest-rising cybersecurity startups
