Senior Platform Engineer

This is a consumer fintech startup, and you will be working with serial entrepreneurs who have built strong consumer brands and innovative products. We value extreme ownership, clear communication, a strong sense of craftsmanship, and the desire to create lasting work and work relationships. Yes, you can build an exciting business AND have real-life real-customer impact.

You'll be one of our first platform engineers building the foundation for our fintech engineering organization as we scale from startup to enterprise-grade operations.

This is not a "keep the lights on" operations role. You'll build internal products - self-service tools and automated workflows that make secure, compliant infrastructure invisible to product teams. Your customers are engineers; your metrics are their velocity and our security posture.

Build & Automate

• Design self-service infrastructure using AWS (ECS, RDS, S3, Lambda, IAM) and Pulumi/TypeScript

• Create automation that eliminates manual work

• Build and optimize CI/CD pipelines for fast, safe deployments

Enable & Scale

• Establish monitoring, alerting, and observability systems

• Build documentation and runbooks that empower teams to self-serve

• Work with product teams to understand friction points

Improve & Secure

• Balance fintech compliance requirements with developer experience

• Participate in incident response and postmortems

• Optimize system performance, scalability, and cost

• Implement security controls that satisfy regulatory requirements

Collaborate

• Treat platform as product: gather feedback, measure adoption, drive improvements

• Partner with engineers and stakeholders to set technical strategy

• Explain technical decisions clearly to non-technical audiences

• 5+ years infrastructure, platform, or DevOps engineering

• Production AWS (EC2, ECS/Fargate, RDS, S3, Lambda, VPC, IAM)

• Infrastructure-as-code (Pulumi or Terraform- we use Pulumi/TypeScript)

• CI/CD pipelines (GitHub Actions, GitLab CI, Jenkins, or similar)

• Containers (Docker, ECS, or Kubernetes)

• Monitoring tools (Datadog, Prometheus, CloudWatch, or similar)

• Strong coding skills in Ruby, Python, Go, TypeScript, or similar

• Track record building platforms that teams actually adopted

• Fintech or regulated industry experience (SOC 2, PCI-DSS)

• Security automation or compliance tooling

• 0→1 infrastructure building experience

• Data and ML infrastructure or MLOps background

During interviews, we'll discuss your focus area. All roles are 70% specialty, 30% general platform work.

Security & Compliance: Secure architectures, IAM systems, security automation, SOC 2/PCI-DSS frameworks, audit preparation

Site Reliability: Observability platforms, intelligent alerting, SLOs/error budgets, disaster recovery, performance optimization

Developer Experience: Self-service provisioning, CI/CD optimization, internal platforms, reusable infrastructure patterns
