Job Title
Senior Platform Engineer (DevSecOps)
Company Description
9fin.com – Series C AI platform for debt markets
Job Description
Join 9fin's high-seniority Platform team to lead the security function from the ground up. You will design and implement the automated guardrails, policy-as-code, and secure-by-default systems that allow engineers to move fast while protecting a platform used by 300+ blue-chip institutions across the $145 trillion global debt market.
Location
Remote, UK
Why this role is remarkable
- Opportunity to build a security function from a "cold start," defining the standards, tooling, and culture for a unicorn-stage fintech.
- 9fin just closed a $170M Series C at a $1.3B valuation, providing massive growth trajectory and stability with 300+ institutional clients.
- Work in a high-autonomy, low-ego environment within a senior Platform team that functions as an internal product group rather than a ticket-based service.
What you will do
- Design and implement automated security guardrails across a multi-account AWS environment using Terraform and policy-as-code.
- Build and maintain secure CI/CD pipelines in GitHub Actions, including secret scanning, dependency analysis, and build integrity checks.
- Partner with the Head of InfoSec to translate SOC 2 compliance requirements into pragmatic, engineering-led platform features and automated gates.
The ideal candidate
- Proven experience owning or significantly improving cloud security posture, ideally building security functions from scratch in a startup/scale-up environment.
- Expert-level proficiency with AWS, Infrastructure as Code (Terraform), and modern application security patterns like decentralized authentication.
- Strong communicator who can balance security requirements with developer experience to influence engineering teams across the entire organization.
