Senior Platform Security Engineer

Monstro is the operating system for governed financial intelligence. We build governance and intelligence infrastructure that enables artificial intelligence to operate safely, explain ably, 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.

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, & 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 Dev Sec Ops  practices that support both innovation and trust.

Security is a strategic priority  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.
