## Description

We're looking for a Senior Software Engineer to design, build, and scale the core systems that power VulnCheck's vulnerability intelligence platform. This is a high-impact, hands-on role where you'll own critical services and data pipelines end-to-end-from design through production.

You'll play a key role in shaping architecture, improving system performance and reliability, and delivering features that directly impact customers. While you'll help resolve production issues, your focus will be on building durable, scalable solutions that prevent them. This is a 100% remote role but we're primarily looking for candidates based in Cheltenham, United Kingdom.

What You'll Do

 * Design and build scalable backend systems, APIs, and data pipelines
 * Own services end-to-end, including architecture, development, deployment, and operation
 * Lead technical design discussions and contribute to system architecture decisions
 * Write high-quality, maintainable code and drive engineering best practices
 * Debug complex production issues and implement long-term, scalable solutions
 * Improve system performance, reliability, and observability across the platform
 * Partner closely with Product, Data, and other Engineering teams to deliver impactful features
 * Mentor junior engineers and contribute to a strong engineering culture
 * Participate in incident response and on-call rotations
