Senior Backend Engineer - Node.js

About Yarrowcast Defense:

Most engagements start with a vulnerability scan and a tabletop exercise with the client's leadership.

About the role:

We are adding a Senior Backend Engineer - Node.js to our Payments team. You'll work mostly on server-side code: services, queues, databases and the glue between them. Little to no frontend work. The Payments team owns services that process several million requests a day. We need another engineer who is comfortable owning them in production.

What you'll work on:

• Add caching with Redis where it actually helps, and remove it where it doesn't
• Reduce cloud costs by right-sizing services and cleaning up unused resources
• Write integration and contract tests so API changes don't break consumers
• Containerize services with Docker and deploy them to Kubernetes or ECS
• Handle on-call for services the team owns and lead incident follow-ups
• Implement background jobs and event consumers using Kafka, SQS or RabbitMQ

You have:

• Working knowledge of message queues or streaming platforms
• Hands-on experience with AWS, GCP or Azure services
• Proficiency in at least one of Go, Java, Kotlin, Python, C# or Node.js
• Understanding of concurrency, transactions, idempotency and retries
• Strong SQL and relational data modeling skills

Desirable:

• Elasticsearch or OpenSearch
• Kubernetes, including Helm charts

Why work with us:

The base pay range for this position is $153,000 - $210,000 per year. Actual pay depends on experience, skills and location.

• Health, dental and vision coverage starting on day one
• 401(k) with 4% match
• Paid sick leave
• Employee discount
• Life insurance

Start: Flexible.
