- **Work type:** onsite
- **Posted:** 2026-08-10
- **Last confirmed live:** 2026-09-07

## Job description

## THE OPPORTUNITY

ModernFi is seeking a Platform Engineer to build the foundation that our platform runs on, alongside a talented and collaborative team. This is a founding Platform Engineering role, and from day one you will work on critical systems with meaningful ownership and a direct hand in shaping the direction of our products and infrastructure. As the technical owner of the platform, you will define how we operate our infrastructure, release software, and approach security across the company.

Your work will be instrumental in building the products that help banks and credit unions operate, improving financial health nationwide. This role offers the opportunity to deliver impactful solutions with real autonomy, work on mission-critical systems, grow your technical expertise, and influence ModernFi's broader trajectory as we grow from serving hundreds of institutions to thousands.

At ModernFi, your work will directly fuel our vision and mission to serve as systemically important financial infrastructure that drives the American economy and to empower our partner financial institutions to grow and better serve their communities.

## THE ROLE

## 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.

## TECH STACK

- AWS / Pulumi IaC
- PostgreSQL (RDS), ECS, Docker
- Temporal
- Python (FastAPI, SQLAlchemy)
- Datadog, PagerDuty, GitHub Actions
- Auth0, Vanta, Fern

## ABOUT YOU

- 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: you treat security as a first-class concern in everything you build, even if you don't come from a dedicated security background. Familiarity with frameworks such as SOC 2, compliance tooling such as Vanta, and concepts such as secrets management, key rotation, and least-privilege access is a plus.
- Hands-on experience with a modern observability stack (Datadog, Prometheus + Grafana, the Elastic stack, or equivalent), and a track record of setting observability and monitoring standards that translate into actionable insights for product teams downstream. You've also defined SLOs, run postmortems, and improved the on-call experiences you've personally experienced.
- Comfortable owning systems end-to-end, from the IaC that provisions them to the runbooks that recover them.
- Experience working in or alongside small, fast-moving engineering teams, with a track record of making them faster and more reliable rather than introducing process drag.
- Excellent communication skills. You can explain a network topology to a non-engineer and a production incident to a CEO with equal clarity.
- High level of empathy, integrity, and calmness under pressure.
- You're excited by the prospect of being the founding Platform Engineer at a fintech company where your work directly determines what we can safely ship. You’re the kind of IC who thrives on shipping infrastructure that other engineers love to build on.
