About Grain
Grain makes it possible to pay with stablecoins anywhere that accepts regular payments. Users pay from their own crypto wallets; merchants receive dollars through regulated banking partners. We never hold customer funds.
Under the hood, we coordinate wallet orchestration, transaction validation, compliance controls, and fiat settlement — bridging crypto-native value with real-world commerce.
We closed our seed round led by Polychain Capital and are focused on scaling infrastructure that meets the security and reliability standards payments demand.
The Role
You'll be our first dedicated DevOps hire. Our platform is processing real transactions today, and we need to harden our infrastructure for SOC 2 compliance, improve observability, and build the operational foundation for scale — all without killing the velocity of a small, focused team.
This is a build-it-right-from-the-start role, not a fix-the-legacy-mess role. You'll have real ownership over our infrastructure philosophy, security posture, and operational practices.
What you'll own:
Observability & reliability — Build comprehensive logging, metrics, tracing, and alerting. Make production systems resilient against outages, misconfigurations, and security threats.
Security & compliance — Establish SOC 2-compliant access controls, secrets management, and audit logging. Design and implement zero-trust architecture across services and APIs.
CI/CD & release management — Build pipelines with automated testing, staged rollouts, and rollback capabilities. Improve deployment velocity without sacrificing safety.
Infrastructure-as-code — Manage and evolve our AWS infrastructure through CDK, ensuring reproducibility and auditability.
Cost & performance — Drive cost optimization as we scale, without compromising reliability.
Developer experience — Partner with engineering to make deploying, debugging, and operating services as smooth as possible.
What We're Looking For
Required:
4+ years in DevOps or infrastructure engineering
Production experience with AWS CDK (or Terraform/Pulumi — but CDK is what we use)
Hands-on Kubernetes in production (EKS strongly preferred)
Built and maintained CI/CD pipelines serving real users
Implemented observability solutions end-to-end (not just installed Datadog)
Solid understanding of security best practices, particularly in financial or payments contexts
You've operated systems where downtime has real consequences — not just dashboards, but pagers
Strong Plus:
Experience with SOC 2, PCI-DSS, or similar compliance frameworks
Background in fintech, payments, or financial services infrastructure
Knowledge of zero-trust architecture and implementation
Experience with blockchain or crypto infrastructure
Technical Stack
Cloud: AWS (CDK for IaC)
Orchestration: Kubernetes (EKS)
Compute: ECS, Lambda, EC2
CI/CD: GitHub Actions (open to your recommendations)
Observability: Building this out — you'll have significant input here
About the Company
Grain is building the infrastructure that makes crypto payments usable in everyday commerce.
We enable merchants to accept digital assets directly at checkout while receiving fiat settlement, creating a unified experience for both sides of the transaction. Customers pay in crypto, merchants receive fiat, and the entire process happens within a single seamless, trusted payment flow.
Our mission is clear. Make payments simple. Make them universal. Make them work for everyone, everywhere.
