Senior Platform Engineer

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.

We're looking for a Senior Platform Engineer to join our growing Platform Engineering team and play a critical role in shaping how we build, deploy, and operate software. You'll work alongside our Staff Platform Engineer and collaborate closely with the broader Engineering team. This role sits at the intersection of enablement and governance—you'll empower our engineering teams to move fast while ensuring everything we do meets the highest standards for security and compliance.

You'll own our GCP infrastructure, build out scalable environments, and establish the standards and tooling that make our engineers productive. At the same time, you'll be the guardian of our security posture and compliance commitments, ensuring we meet NIST and SOC-2 requirements without slowing down innovation.

• Build and maintain our GCP infrastructure, creating consistent, repeatable environments across development, staging, and production
• Design and implement CD pipeline standards that enable teams to deploy confidently and frequently
• Develop internal tooling, templates, and automation that reduce friction for software engineers
• Create and maintain infrastructure-as-code (Terraform) to ensure environments are reproducible and auditable
• Provide support and guidance to engineering teams on platform best practices
• Continuously improve developer experience by identifying and eliminating bottlenecks

• Implement and maintain security controls across our GCP environment (IAM, VPC configuration, secrets management, encryption)
• Maintain comprehensive documentation and evidence for internal and external audits
• Conduct security reviews and work with teams to remediate vulnerabilities
• Build observability and logging infrastructure that meets compliance retention and integrity requirements

• Work as part of the Platform Engineering and Engineering teams to understand needs and deliver solutions
• Partner with the Staff Platform Engineer on architecture decisions and platform strategy
• Participate in incident response, root cause analysis, and postmortems
• Contribute to architectural decisions and help establish engineering standards
• Mentor team members and share knowledge across the organization

Required:

• 5+ years of experience in platform engineering, DevOps, SRE, or infrastructure roles
• Strong hands-on experience with Google Cloud Platform (GCP) and Azure
• Proficiency with infrastructure-as-code tools, particularly Terraform
• Experience designing and implementing CI/CD pipelines (GitHub Actions, Cloud Build, or similar)
• Solid understanding of security principles and experience implementing security controls in cloud environments
• Familiarity with compliance frameworks (NIST, SOC-2) and implementing controls to meet audit requirements
• Strong scripting and automation skills (Python, Bash, or similar)
• Excellent communication skills and ability to work collaboratively with engineering teams

Nice to Have:

• Experience in Fintech or other regulated industries
• Knowledge of Kubernetes and container orchestration
• Experience with API management platforms (e.g., Apigee)
• Background in observability tools (Datadog, Prometheus, Grafana, or similar)
• Relevant certifications (GCP Professional, CISSP, etc.)
• Experience NIST compliance frameworks (CSF, 800-53) including access controls, continuous monitoring, and risk management
• Experience supporting SOC-2 compliance by implementing controls for security, availability, and confidentiality, along with auditable change management processes

• Ownership & Impact: Shape the future of AI-powered finance—building a category-defining product used by consumers and institutions around the world.
• Experienced Team: Join a team with leadership that has a track record of scaling companies from early stage to major exits.
• Principles-Driven Culture: Work in a culture that values speed, ownership, and impact—what most companies achieve in 90 days, we do in 45.
• Comprehensive Compensation Package: Competitive salary, equity, and robust benefits package, including paid health, vision, dental, and disability coverage.
