Job Description

Hi, I’m Stephen, Director of Engineering at Customer.io. I’m looking for a Senior Backend Engineer to join our growing Engineering team!

Some things you’ll do

  • Architect and build highly scalable, distributed systems in Go that handle mission-critical workloads.
  • Lead design discussions and set best practices for fault tolerance, system reliability, and performance optimization.
  • Influence the technical roadmap by identifying key opportunities for innovation and improvement.
  • Drive large-scale architectural decisions, ensuring the platform is built for growth and operational excellence.
  • Enhance inter-service communication by improving RPC frameworks, event-driven architectures, and data pipelines.
  • Develop infrastructure automation to streamline deployments, monitoring, and scaling using Kubernetes, Terraform, and CI/CD tooling.
  • Implement and refine observability strategies, leveraging tools like OpenTelemetry, Prometheus, and distributed tracing.
  • Mentor and support engineers, fostering a culture of technical excellence and continuous learning.
  • Collaborate across teams, influencing product, security, and infrastructure decisions to align with long-term company goals.

About you

  • Expertise in distributed systems architecture, including consensus algorithms, CAP theorem, eventual consistency, and leader election.
  • Strong proficiency in Go (or another strongly typed language like Java, Rust, or Kotlin) with experience building high-performance services.
  • Deep knowledge of cloud infrastructure (AWS, GCP, or Azure) and best practices for scalability, networking, and security.
  • Hands-on experience with Kubernetes, Docker, and container orchestration tools.
  • Proficiency in infrastructure as code (Terraform, Pulumi, or CloudFormation) to automate cloud-based deployments.
  • Experience working with event-driven architectures, messaging systems (Kafka, NATS, RabbitMQ), and real-time data processing.
  • Passion for automation, with experience designing and implementing CI/CD pipelines (GitHub Actions, ArgoCD, Jenkins).
  • Strong understanding of observability and debugging techniques, including monitoring, logging, and distributed tracing.
  • Excellent problem-solving skills, with the ability to diagnose and resolve complex system issues efficiently.
  • Proven track record of leadership, mentoring engineers, driving best practices, and influencing engineering culture.

What we’re looking for

  • 10+ years of experience in software engineering, with a focus on distributed systems, backend infrastructure, or platform engineering.
  • 5+ years of experience designing and deploying large-scale distributed architectures in cloud environments.
  • Demonstrated ability to lead and influence technical decisions across multiple teams.
  • Proven experience designing and optimizing APIs and service-to-service communication patterns (gRPC, REST, GraphQL).
  • Deep experience with databases (PostgreSQL, MySQL, DynamoDB, or BigTable) and performance tuning strategies.
  • A security-first mindset, ensuring best practices for authentication, authorization, and data protection.
  • Strong communication skills, with the ability to present complex technical concepts to diverse audiences.
  • A DevOps mindset, embracing automation, testing, and continuous delivery.
  • An AI-forward mindset, leading by example in integrating AI tools into engineering workflows to help the organization prototype, iterate, and ship more effectively.
  • Passion for mentoring and growing engineers, fostering an environment of collaboration and knowledge sharing.
