Senior Platform Security Engineer

About Monstro

Monstro is a governed AI platform for regulated financial institutions. We give banks and wealth managers a way to deliver trusted advice digitally — to every client, not just the top tier.

Institutions already have the relationships, data, and context to understand each client. Monstro turns that understanding into advice. It gives every client the experience of a personal advisor: bringing together their full financial picture, identifying what matters, and delivering personalized guidance across investments, tax, retirement, insurance, legal, and more.

For clients, that means clearer decisions, proactive support when life changes, and a better view of their financial lives. For institutions, it means deeper relationships, more clients served consistently, and more of each client's financial life managed in one place.

What makes this possible is how the system is built. Every recommendation reflects the institution's own views, policies, and permissions. Every output is auditable, traceable, and reversible, and client data stays under the institution's control. Generative AI shapes how advice is designed; at runtime, execution is deterministic — so every output can be explained and stood behind, not just trusted.

The work

We are building for a high-stakes industry where the work has real consequences. The challenge is to make advice more personal and more available without making it less trusted — to build AI that institutions can audit, explain, and reverse, in a domain where being wrong carries real cost. That is a hard problem, and it is the reason to be here.

You will work on technology that brings real financial advice to people who have rarely had access to it. You will be expected to think clearly, move with urgency, hold a high bar, and take responsibility for work that matters. We are an early team building something ambitious, and what you do here will shape both the product and the company.

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.

What You'll Own

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
