Infrastructure Engineer

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
