You will take end-to-end ownership of critical infrastructure systems, from technical design and development through deployment, operation, and continuous improvement. The position combines cloud architecture, distributed systems, reliability engineering, observability, performance optimization, and developer tooling. You will partner closely with product engineering, security, and DevOps teams to build secure, resilient, scalable, and cost-efficient systems. As a senior technical contributor, you will also influence engineering practices, mentor colleagues, and help resolve complex infrastructure challenges. This is a strong opportunity for a systems-minded engineer who thrives with significant autonomy in a globally distributed, fully remote environment. Accountabilities: * Take full ownership of a core infrastructure product or subsystem end to end, including design, development, deployment, operation, and production performance. * Define project goals and success metrics, align technical work with organizational objectives, and proactively identify and mitigate risks. * Translate product requirements and technical specifications into practical designs that address critical edge cases without unnecessary complexity. * Build secure, reliable, resilient, high-performing, and cost-efficient infrastructure for diverse applications and workloads. * Design, develop, and deploy production software and developer-facing tools that improve engineering workflows and reduce operational toil. * Manage infrastructure through code and configuration, primarily using Terraform and established architectural patterns. * Partner with product engineering teams to design services for scale and resolve ambiguous technical requirements with stakeholders. * Participate in incident response and apply systematic debugging techniques to diagnose infrastructure and service issues. * Develop and improve monitoring and observability practices, using operational data to identify stability, performance, and reliability improvements. * Apply a security-focused mindset across infrastructure development, implementation, and peer reviews by proactively identifying potential vulnerabilities. * Serve as a technical resource for complex infrastructure challenges and mentor engineers through code reviews, pairing, and design feedback. * Drive collaboration across engineering and other stakeholder groups, facilitating discussions around technical decisions, processes, and infrastructure strategy. ## Related Videos - [Reducing LLM Calls with Vector Search Patterns - Raphael De Lio (Redis)](https://www.wearedevelopers.com/videos/1714-reducing-llm-calls-with-vector-search-patterns-raphael-de-lio-redis) - [Shifting Stress to Progress— Understanding DevOps to do DevOps Better](https://www.wearedevelopers.com/videos/268-shifting-stress-to-progress-understanding-devops-to-do-devops-better) - [Monitoring as Code - Managing your dashboards at scale](https://www.wearedevelopers.com/videos/753-monitoring-as-code-managing-your-dashboards-at-scale) - [Reducing Cognitive Overload Through Platform Engineering](https://www.wearedevelopers.com/videos/679-reducing-cognitive-overload-through-platform-engineering) - [Accelerating Authentication Architecture: Taking Passwordless to the Next Level](https://www.wearedevelopers.com/videos/733-accelerating-authentication-architecture-taking-passwordless-to-the-next-level) - [Shipping Faster with Less: Render on Cloud Hosting, AI Workloads, and the Future of DevOps](https://www.wearedevelopers.com/videos/1894-shipping-faster-with-less-render-on-cloud-hosting-ai-workloads-and-the-future-of-devops) ## Related Articles - [Top-Paying Tech Jobs (with Salaries)](https://www.wearedevelopers.com/magazine/372-top-paying-tech-jobs-with-salaries) - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [The Most Popular IT Jobs on the Market](https://www.wearedevelopers.com/magazine/376-the-most-popular-it-jobs-on-the-market) - [What Are The Top Skills Required For Azure Developers?](https://www.wearedevelopers.com/magazine/77-what-are-the-top-skills-required-for-azure-developers) - [The 12 Best Jobs for Software Engineers](https://www.wearedevelopers.com/magazine/401-the-12-best-jobs-for-software-engineers) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs)
