Windows Specialist in London

Hello. We’re Teya. Teya was founded on a simple belief: local businesses deserve better. They are the cafés, restaurants, salons, shops and entrepreneurs that bring character to our high streets, create jobs and keep communities moving. Yet for too long, financial services has made life harder for them - with clunky tools, poor support and complexity that gets in the way of running a business. Teya exists to change that. We’re building a financial platform for local businesses across Europe - one built around simple tools, thoughtful design and real human support. Our Members rely on us to help them run their business with confidence, and that responsibility shapes the way we work. We move fast. We care about quality. We stay close to the detail. And we believe great performance and genuine hospitality should go hand in hand. If you want to build meaningful products, solve real problems and make a genuine difference for local businesses, we’d love to hear from you.

Your Mission

As a SecOps Specialist, you protect Teya by detecting, investigating, and responding to security incidents while ensuring our security operations are reliable, scalable, and continuously improving. You will lead complex SOC investigations, provide L3 support, maintain and improve core security tooling, and build automations and integrations that increase speed, consistency, and quality across security operations. You will work closely with Security Engineering, IT, Infrastructure, Platform, Cloud, and Product teams to reduce risk and embed security effectively across the organisation. You operate across incident response, detection engineering, security tooling, vulnerability management, threat intelligence, telemetry, and automation - turning operational insight into stronger controls and better engineering outcomes.
