Senior Platform Security Engineer

About the role

We're looking for a Senior Platform Security Engineer to help build and secure the infrastructure that powers Monstro's AI platform. This is a hands-on engineering role focused on creating reliable, scalable, and secure systems while embedding security throughout the software development lifecycle. You'll sit at the intersection of platform engineering, cloud infrastructure, security operations, and compliance. Your mission is to build and maintain scalable, secure, and compliant infrastructure that enables engineering teams to move quickly with confidence. Alongside building and securing our platform, you'll help mature the controls, processes, and evidence required to support compliance initiatives such as SOC 2 and ISO 27001 as Monstro continues to scale. Working with financial institutions requires a high bar for security, governance, and operational resilience, and you'll play a critical role in ensuring our infrastructure meets those expectations without compromising engineering velocity. As we continue to scale our platform and expand our regulated AI infrastructure, you'll play a key role in designing deployment pipelines, automating infrastructure, strengthening security controls, and driving operational excellence across our cloud environments. You'll help build the technical foundations that allow Monstro to remain secure, compliant, and audit-ready while supporting the rapid development and deployment of AI-powered products. This is not a role where security operates separately from engineering. We believe the strongest security posture is built into the platform from day one. You'll work closely with software engineers, product teams, and leadership to establish DevSecOps practices that support both innovation and trust. Security is a strategic priority at Monstro. As a company building infrastructure for financial institutions, we operate in an environment where trust, resilience, and compliance are foundational to our success. This role will have meaningful visibility and influence across the organization, helping shape the systems, controls, and operational practices that protect both our platform and our customers while enabling engineering teams to move quickly and safely. No two days look the same. You may be improving Kubernetes deployment workflows in the morning, responding to a security alert in the afternoon, helping prepare evidence for a compliance review, and designing infrastructure improvements that reduce operational risk before the day is done.

Responsibilities

• Platform Engineering & Infrastructure
• Design, build, and maintain scalable cloud infrastructure across GCP and supporting cloud platforms
• Implement and manage infrastructure-as-code using Terraform. Experience with Terraform is preferred, though equivalent experience with infrastructure automation tools such as Pulumi, CloudFormation, Ansible, or similar technologies is also valued.
• Manage containerized environments and orchestration platforms including Docker and Kubernetes
• Drive reliability, performance, and scalability improvements across production systems
• Support disaster recovery, business continuity, and infrastructure resilience initiatives
• Partner with engineering teams to improve developer experience and deployment velocity
• Partner with AI and product engineering teams to build the infrastructure foundations for agentic systems, enabling secure, scalable, and reliable deployment of AI-powered workflows and services.
• DevOps & CI/CD
• Design, implement, and optimize CI/CD pipelines using GitHub Actions, GitLab CI, Jenkins, Azure DevOps, or similar technologies
• Automate build, testing, deployment, and operational workflows to reduce manual effort and improve consistency
• Champion GitOps and infrastructure automation practices across engineering teams
• Establish monitoring, observability, and alerting frameworks using tools such as Prometheus, Grafana, Datadog, and ELK
• Improve deployment reliability and operational metrics through continuous platform enhancements
• Security Operations & Governance
• Embed security controls throughout the software development lifecycle through a DevSecO

Additional Information

About Monstro Monstro is the operating system for governed financial intelligence. We build governance and intelligence infrastructure that enables artificial intelligence to operate safely, explainably, and at institutional scale. We exist because the level of financial guidance historically available to a small group should be accessible to many more people. By combining AI with deep institutional infrastructure, we help financial institutions deliver more personalized, responsible, and life-changing financial support to millions of individuals. We're building mission-critical systems in a highly regulated domain, and we care deeply about doing it right. If you're motivated by meaningful problems, high standards, and shaping infrastructure that improves financial outcomes, you'll feel at home here.
