Senior Platform Engineer

Storm2; California; Remote; USD 190,000 - 230,000; Full time

Job summary

Storm2’s client, a payments infrastructure FinTech, seeks a Platform Engineer to own significant pieces of the platform, from Terraform migrations to CI/CD and observability. This lean team requires engineers who can implement production changes with independence and build tooling to accelerate others.

You will work across cloud providers (GCP/AWS/Azure), Kubernetes/ECS, and Go/Python/TypeScript, shaping secure, observable infrastructure with strong ownership.

Qualifications

• 5+ years across platform, infrastructure or backend engineering with production infra ownership.
• Experience with IaC tools: Terraform, Pulumi or CloudFormation.
• Production cloud experience with AWS/GCP/Azure (GCP preferred).
• Experience building CI/CD and internal tooling, not just using a platform.
• Backend language experience: Go, Python or TypeScript.
• Hands-on observability tooling: Datadog, Grafana, Prometheus or OpenTelemetry.
• Strong IAM, secrets management and secure-by-default infrastructure.

Responsibilities

• Own infrastructure-as-code across networking, IAM, VPCs and provisioning, including Terraform migrations.
• Hardening CI/CD, secrets management and self-service deployment tooling.
• Build internal abstractions and tooling for product engineers to ship faster.
• Expand observability across instrumentation, metrics, monitoring and alerts.
• Support production cloud infra and reliability across messaging systems.
• Develop tooling for compliance, access controls and remediation.
• Improve developer onboarding, local workflows and infra documentation.

Job description

Platform Engineer – Payments Infrastructure

United States, Remote-first

$190k–$230k base + equity

The Company

Storm2’s client is a payments infrastructure FinTech processing billions of dollars in annual transaction volume. Their APIs power real-time transfers, bank debits and card disbursements for FinTech, banking and marketplace businesses, so reliability and compliance are built into the infrastructure rather than bolted on later.

They’re growing a lean infrastructure team and need another engineer who can take meaningful ownership without relying on a mature platform organisation around them.

The Role

Platform engineering gets interesting when a bad infrastructure decision can affect real money moving in real time.

You’ll own significant pieces of the platform underneath the engineering team, from Terraform and environment provisioning through to CI/CD, observability and internal developer tooling. There’s a defined backlog to attack, but not layers of process telling you how to execute it.

This isn’t a role for someone who’s only operated inside a platform that was already mature. They need someone who’s built or materially improved infrastructure themselves, can safely make production changes with a high degree of independence, and likes creating tooling that makes every other engineer faster.

What you’ll be working on:

• Owning infrastructure-as-code across networking, IAM, VPCs and environment provisioning, including an ongoing Terraform migration
• Hardening CI/CD, secrets management and self-service deployment tooling
• Building internal abstractions and tooling that let product engineers ship without becoming infrastructure experts
• Expanding observability across service instrumentation, metrics collection, monitoring and alerting
• Supporting production cloud infrastructure and reliability across messaging systems
• Building tooling around compliance, access controls and infrastructure remediation
• Improving developer onboarding, local development workflows, cloud cost visibility and infrastructure documentation

What you’ll bring:

• 5+ years across platform, infrastructure or backend engineering, with substantial production infrastructure ownership
• Strong Terraform, Pulumi, CloudFormation or comparable infrastructure-as-code experience
• Production experience with GCP, AWS or Azure, with GCP particularly relevant
• Experience building CI/CD and internal developer tooling, rather than simply using an established platform
• Kubernetes, ECS or similar container orchestration experience
• Backend engineering ability in a language such as Go, Python or TypeScript
• Hands‑on knowledge of observability tooling such as Datadog, Grafana, Prometheus or OpenTelemetry
• A strong understanding of IAM, secrets management and secure‑by‑default infrastructure
• Comfort making production infrastructure changes independently in a small engineering team

Where you’ll stand out

Experience in payments, FinTech or another regulated environment will translate particularly well. The same goes for engineers who’ve built compliance‑focused platform tooling, worked across GCP and AWS, or supported infrastructure through rapid transaction or engineering‑team growth.

The important distinction is ownership. If your experience is mostly maintaining infrastructure someone else designed, this probably isn’t the right one. If you’ve been the engineer improving the platform while product teams are actively depending on it, it probably is.
