About the role

Platform Engineer at ModernFi responsible for building and owning the platform infrastructure, release pipelines, security and compliance, observability, and reliability as a founding Platform Engineer in a fintech environment.

Responsibilities

  • Own and evolve the reliability posture of the ModernFi network (observability, incident response, SLOs, and on-call practices) so we can keep shipping fast without ever compromising correctness.
  • Lead the buildout of a more advanced release pipeline with merge queues, feature-flag tooling, and per-domain release gates for our highest-stakes services across multiple environments.
  • Take ownership of our cloud platform, Pulumi modules, AWS account structure, identity, networking, and the tooling product engineers build on, and make the right call between extending what we have today and replacing it for what's next.
  • Drive our security and compliance posture: Vanta remediation, SOC 1/2 readiness, vulnerability scanning, secrets and key management, and hardening across the stack — partnering closely with our CCO, external advisors, and the rest of engineering.
  • Upgrade how ModernFi does on-call: the tooling around it, the runbooks behind it, the rotations that staff it, and the postmortems that close it out while participating in the infrastructure on-call rotation yourself.
  • Partner closely with our product engineering pods to understand where the platform creates drag, and ship the abstractions that let them move faster and more safely.
  • Cultivate a culture of operational excellence through code reviews, design discussions, mentorship, and the steady raising of our collective bar for what production-grade looks like.

Qualifications

  • 5+ years of software engineering experience, with significant time spent on infrastructure, platform, or reliability-focused work in a production environment.
  • Deep fluency with cloud infrastructure (ideally AWS), infrastructure-as-code (Pulumi, Terraform, or similar), and modern CI/CD pipelines.
  • A security mindset: familiarity with SOC 2, compliance tooling such as Vanta, secrets management, key rotation, and least-privilege access is a plus.
  • Hands-on experience with a modern observability stack (Datadog, Prometheus + Grafana, Elastic stack, or equivalent), and a track record of setting observability and monitoring standards that translate into actionable insights for product teams downstream. Defined SLOs, run postmortems, and improved on-call experiences.
  • Comfortable owning systems end-to-end, from the IaC that provisions them to the runbooks that recover them.
  • Experience in small, fast-moving engineering teams, with a track record of making them faster and more reliable.
  • Excellent communication skills capable of explaining complex network topology to non-engineers and production incidents to leadership.
  • High empathy, integrity, and calmness under pressure.
  • Excitement about being the founding Platform Engineer at a fintech company and shipping infrastructure that other engineers love to build on.
