About Bastion

Bastion builds regulated financial infrastructure for modern businesses. Bastion's full stack product suite covers stablecoin issuance, custodial wallet infrastructure, and global asset conversion rails, with the flexibility to deploy individual capabilities or combine them end-to-end.

Bastion's regulated foundation underpins a compliance-first approach to risk management, ensuring the integrity and security of all financial activity within its systems. Bastion holds the appropriate licenses for its own operations, but can also act as a service provider, offering compliance and financial operations support under our customers’ licenses.

Work to Be Done

Instead of a list of requirements, we want to give you a directional look into the first 30, 90, and 180 days on the job.

We are a startup, so the pace is fast and the specific work will change. You need to be okay with that.

If you think this is something you can handle, we will be excited to speak with you.

We are open to US remote and have an office in New York City.

First 30 days: Learn the infrastructure, ship confidently

• Ramp on AWS architecture, Terraform patterns, Kubernetes setup, CI/CD pipelines, and observability stack
• Ship a small infrastructure improvement: Terraform module refactor, monitoring enhancement, or CI/CD optimization
• Add runbooks, alerts, or documentation for the infrastructure areas you touch
• Outcomes
• Multiple safe infrastructure changes deployed with verification
• You understand our core infrastructure patterns and can navigate Terraform, K8s, and AWS resources
• Updated documentation and/or infrastructure-as-code improvements that help the team
  

By 90 days: Own an infrastructure domain and raise the bar

• Take ownership of an infrastructure area: CI/CD pipelines, observability stack, Kubernetes platform, or AWS security/networking
• Lead a medium-scope project: implementing a reusable Terraform module, right-sizing service resources, or improving deployment reliability
• Strengthen system reliability with better metrics, alerts, autoscaling policies, and failure recovery mechanisms
• Outcomes
• A delivered infrastructure improvement that enhances reliability, reduces cost, or improves developer velocity
• You're a go-to person for your infrastructure domain
  

By 180 days: Drive platform-wide impact

• Lead a platform-wide initiative: single immutable image pipeline, infrastructure standardization, database performance optimization, or security hardening
• Shape infrastructure direction with design docs, RFC proposals, and mentoring engineering teams
• Partner with engineering, security, and compliance teams to make pragmatic tradeoffs on reliability, cost, and regulatory requirements
• Outcomes
• A multi-sprint infrastructure delivery that improves system-wide reliability, security, or developer experience
• Clear before/after improvements in deployment speed, cost efficiency, or operational stability
• Patterns and tooling that enable engineers to ship faster and safer
  

Some problems you might work on

• Building reusable Terraform modules that standardize service deployment patterns across dev, sandbox, and prod
• Implementing single immutable image pipelines with built-in security scanning and promotion workflows
• Right-sizing Kubernetes workloads and autoscaling policies to reduce cost while maintaining reliability
• Designing and implementing database monitoring and performance optimization strategies
• Hardening AWS infrastructure with security best practices: IAM policies, network segmentation, secrets management, and audit logging
• Building observability infrastructure that gives engineers fast feedback on system health and performance
• Improving CI/CD reliability and speed through better caching, parallelization, and failure handling
  
  

Our typical stack

• Languages: Go and TypeScript/Node.js; some services in Rust as needed
• Infrastructure-as-Code: Terraform
• Cloud & Compute: AWS (ECS, EKS, Lambda, EC2), Kubernetes, Docker
• CI/CD: GitHub Actions, container registries, automated testing and deployment pipelines
• Data: Postgres (RDS), Redis, Kafka, Snowflake
• Workflow Management: Temporal
• Security: AWS Nitro Enclaves for hardware-backed key isolation, IAM policies, secrets management
• Observability: Datadog, Grafana, Sentry, CloudWatch
• Incident Management: Incident.io
