Remote-first (UK) | £80,000-£100,000 + equity

We’re hiring for a UK cyber security startup building a platform that helps organisations detect malicious open-source code and secure their software supply chain in real time.

The product continuously scans dependencies, surfaces risk clearly, and helps teams prevent compromised packages from entering the codebase - without slowing engineering down.

If you’re a strong full stack engineer who enjoys building clean, scalable product and you’re curious about cyber security, this is a chance to build something genuinely important.

Why this is interesting (especially if you like cyber)

Open source and third-party dependencies are now one of the biggest attack paths for modern organisations.

This team is tackling that head-on with a platform designed for both engineering and security teams - offering malware detection, deep dependency visibility, and policy enforcement to stop bad code early.

They’re also part of a leading UK cyber security accelerator programme, supporting the next generation of high-growth security startups.

The role

You’ll join a small, high-output engineering team and build customer-facing features end-to-end - front to back to cloud.

You’ll ship frequently, own features, and have real influence over architecture and product direction.

This role includes LLM exposure, but the emphasis is practical integration via APIs (plugging LLM capabilities into workflows), not building research-heavy or RAG-first systems.

What you’ll do

Build and ship product features across the stack (UI → API → cloud)
Develop back-end services in Python, delivering reliable, well-tested APIs
Build responsive, intuitive front-ends in React
Work within an AWS serverless environment (event-driven services, APIs, scalable data patterns)
Integrate external services (including LLM APIs) to enhance workflows and automation
Collaborate closely with founders and product to shape requirements and deliver fast
Improve reliability, performance, monitoring, and developer experience as the product scalesWhat you’ll be building (product context)

The platform focuses on software supply chain security, including capabilities such as:
Detecting malicious or tampered open-source packages
Providing deep insight into dependency trees and hidden risk
Preventing compromised code from reaching production environments
Helping organisations enforce security policies early in the SDLCWho you are

You’re a capable Full Stack Developer who has:
Strong commercial experience building web applications with React and Python
Hands-on experience in an AWS Serverless setup (Lambda, API Gateway, DynamoDB, event-driven architectures)
Confidence integrating external APIs, including modern LLM/AI services
A product mindset: you care about usability, clarity, and shipping value
Comfort working in a startup environment - ownership, pace, and ambiguity
An interest in cyber security or secure software development (no need to be an AppSec specialist already)Tech stack (high level)

Frontend: React
Backend: Python (APIs/services)
Cloud: AWS Serverless
AI: LLMs via API integrations (workflow enhancement + automation) experience is beneficial
Package

£80,000-£100,000 base salary (depending on experience)
Equity opportunity
Remote-first across the UK with flexibility and autonomy
High impact: your work will directly shape the platform and customer experienceInterested?

If you’re excited by full stack engineering and want to build meaningful software in cyber security, get in touch with a CV / LinkedIn and a quick summary of what you’ve been working on recently (especially anything serverless or API integration heavy)
