Dex is an AI recruiter agent that helps you run your job search. Tell Dex your stack, seniority, and what you want to build. We will manage your applications and surface other opportunities that are a fit.
The Role
This company builds AI systems that automate how major financial institutions produce and validate client-ready work, turning complex, manual analysis into automated workflows for global banks, private equity, and credit firms. They're backed by leading investors, with significant Series A funding to scale their rapidly growing enterprise AI platform.
This isn't a maintenance role. You're the first platform leader, defining the entire cloud strategy and building the team from scratch. You'll own the architecture, scale their Azure/AKS environment, and implement the security and compliance measures (SOC 2, ISO 27001, GDPR) that enable a product handling sensitive financial data. This is a rare seat: full mandate, significant resources, and no inherited legacy.

What You Bring
- 10+ years in infrastructure or platform engineering, with deep experience architecting and operating production Kubernetes and Terraform at scale.
- Proven track record building, leading, and scaling high-performing platform teams in fast-growth startup environments.
- End-to-end ownership of critical infrastructure, from initial architecture and deployment through production support, observability, and on-call.
- Expertise implementing and navigating security and compliance frameworks (SOC 2, ISO 27001, GDPR) for regulated environments.
