modernfi - Senior/Staff Software Engineer - Platform & Infrastructure

• 1. 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. • 2. 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. • 3. 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. • 4. 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. • 5. 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. • 6. 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. • 7. 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.
