Description
At Gradient Labs, we’re building an AI agent to redefine customer experience and operational efficiency in the financial services sector.
Founded in 2023, we’ve quickly gone from an idea to a growing team with customers you know (and probably love). Our powerful AI agent is unique: it’s the only AI operations agent built specifically for financial services, handling even the trickiest, high-stakes customer queries safely and effectively. Crucially, it serves as one unified agent across the entirety of your customer operations, giving businesses the comprehensive visibility and control they need to trust all outcomes.
We’re a small but mighty team of builders from leading companies like Monzo, Pleo, and Google. If you’re excited to tackle some of the hardest problems in AI and help shape the future of customer operations and experience, we’d love to hear from you.
🎯 How You’ll Make An Impact
We're looking for our Founding Platform & Security Engineer – a highly skilled and passionate individual to join our growing team. In this critical, greenfield role, you'll have significant ownership in shaping and securing our cutting-edge AI agent platform and underlying infrastructure from the ground up.
Reporting directly to the CTO, you'll lead the technical vision for Platform & Security, collaborating closely with AI, engineering and product teams to scale and safely deploy our platform across our and others’ cloud environments. This is an exciting opportunity to apply deep security expertise, particularly in the realm of AI, and build enterprise-grade security systems in a rapidly evolving environment.
