Fullstack Engineer (AI)

TL;DR

Fullstack Engineer (Backend/DevOps): Building, scaling, and operating core systems for a distributed energy platform with an accent on backend microservices, cloud infrastructure, and reliability. Focus on designing scalable systems, ensuring platform reliability, and improving observability in a Kotlin/AWS/Kubernetes environment.

Location: Must be based in the European timezone. hirify.global is a US-based company, so flexibility in working hours is appreciated for cross-timezone collaboration.

Company

hirify.global is a privately-held tech company with VC funding, focused on combating climate change by enabling a reliable electric grid through distributed energy resources.

What you will do

• Contribute to backend development within our Kotlin-based microservices platform, ensuring high performance and reliability.
• Work with product and design to understand user needs, shape product direction, and validate ideas.
• Partner with product teams to integrate new features with our event-driven architecture and domain services.
• Participate in on-call rotations, incident response, and root-cause analysis for continuous improvement.
• Design, build, and maintain cloud infrastructure on AWS using Infrastructure-as-Code (Terraform).
• Operate and improve Kubernetes-based production systems, ensuring availability, performance, and resilience.
• Build and maintain CI/CD pipelines (GitLab) to enable fast, safe, and repeatable deployments.
• Improve observability across the stack (metrics, logs, tracing, alerting, SLOs, dashboards) using Datadog and other tooling.
• Make small to medium frontend (React) changes to support new features or improve UX.
• Actively use and advocate for AI-powered development tools (e.g., Claude Code, GitHub Copilot) to improve development velocity and code quality.
